Mobile cranes shall comply with California Code of Regulations (CCR) Title 8, General Industry Safety Orders, Article 93. Construction crane operations including assembly and disassembly shall comply with 29 Code of Federal Relations (CFR) 1926 Subpart CC. Unless approved by the LBNL Rigging Supervisor, rigging equipment and devices shall comply with American Society of Mechanical Engineers (ASME) B 30.26, have legible load rating markings that are traceable back to the manufacturer, and be made in the USA.
A Crane Lift Plan shall be submitted by the crane subcontractor to the Construction Manager and shall be approved prior to any crane operation. Crane Lift Plans shall include the following:
All crane operators shall have a valid license from an approved agency or union and meet the requirements of 29 CFR 1926 Subpart CC.
All crane signal personnel must meet the signal-person requirements of 29 CFR Subpart CC. Training certificates must be issued by a third-party qualified evaluator, or the CURRENT employer’s qualified evaluator.
All rigging personnel must meet the rigging Competent Person requirements of 29 CFR Subpart CC. All cranes shall be equipped with the following items: rated load capacities, wind load ratings, and special hazard warnings.
All rigging equipment shall be inspected prior to each use, as well as weekly, with a copy of the weekly inspection report submitted to the LBNL Construction Manager.
Wedge sockets and fittings shall be the proper size to match the wire rope and shall move to wedge and hold the wire rope under load construction. The dead end shall be terminated according to ASME B30.5 and shall not be attached in any manner to the live side of the load line.
An anti two-block device or warning device is required on all cranes except pile-driving equipment.
Unless approved by the LBNL Rigging Supervisor and project Construction Manager, multiple-piece lifts (Christmas treeing) are NOT permitted.
A.1.3 ALL CRANES Used on LBNL Projects Must Meet the Following Minimum Criteria
A daily and monthly inspection shall be performed while the cranes are in use on the project. These daily and monthly forms are to be maintained on file by the subcontractor, and made available to the LBNL Construction Manager or LBNL Construction Safety Engineer upon request for review and verification.
If the crane manufacturer's rated load chart for the specific crane configuration is not available on the crane, the crane shall be immediately taken out of service.
When two cranes are working in the same area, a procedure shall be submitted to the LBNL Construction Manager explaining method of coordination to be used between cranes to prevent the possibility of a collision.
Mobile cranes shall only be used with outriggers fully extended and tires off the ground unless the manufacturer allows otherwise.
If supporting ground for the crane is soft, the lift shall not be made until firm bearing is provided, including crane mats if necessary. No lift shall be made if the crane is not level.
If the full range of motion of the lift is not visible to the operator or signal person, radio communication shall be provided.
For multiple-crane lifts, the cranes’ rated capacity shall be reduced by not less than 25%.
A.1.4 Critical Lift Requirements at LBNL
High-consequence/high-value lifts are parts, components, assemblies, or lifting operations designated as such by the customer or program organizations because the effect of dropping, upset, or collision of items could:
In addition, any lift/move that requires the simultaneous use of both the main and auxiliary hoists of a given crane or the simultaneous use of two cranes, lifts within 50 feet of energized overhead power lines, lifts that meet or exceeds 85% of the configured crane capacity . shall be considered a high-consequence/high-value lift/move.
A.1.5 High-Consequence/High-Value Lifts at LBNL
A detailed, step-by-step procedure in the form of an Engineering Note must be prepared for each high-consequence/high-value lift/move. A sample Engineering Note format may be obtained from the Engineering Division.
While high-consequence/high-value lift procedures are customarily prepared for one-time use, general high-consequence/high-value lift procedures may be employed to accomplish routine recurrent high-consequence/high-value lift operations. For example, a general high-consequence/high-value lift procedure may be used to lift shielding blocks or to lift a frequently lifted item in a shop.
Responsibility for preparing the high-consequence/high-value lift Engineering Note rests with the customer, typically the Project Engineer. The customer can discharge this responsibility by indicating on the Facilities Work Request that the scope of work should include preparation of the Engineering Safety Note and management of the move. It is the responsibility of the customer to notify all personnel whose approval is required early in the process. See Approval of High-Consequence/High-Value Lift Procedures, below. Approvers have special expertise and are available to provide guidance during the design of the lifting procedure. Please allow sufficient time for the review and approval process. There is no charge for the review and approval process.
The procedure must contain the following:
A rigging sketch or sketches must include the following:
When particular types of lifts are to be repeated many times (for example, lifts of items with special lifting features that do not allow variation of the parameters listed above, such as center of gravity, lift point, sling angle, and maximum weight) and set procedures are established for them, no new procedures are required. A new checklist must be completed for each separate lift. However, when the items to be lifted are different (for example, if they are unbalanced and do not have the same center of gravity), separate procedures must be written to specify the type of item to be lifted and the specific lifting equipment used. Where the design of the facility permits no significant variation in the travel path, the path does not have to be specified. The procedure must, however, clearly define the limits of the procedure. Also, when there is limited access to the crane operational view and control, the PIC’s responsibility may be delegated to a specified operator.
A.1.6 Approval of High-Consequence/High-Value Lift Procedures
The procedure must be reviewed and approved by:
Any change to the procedure must be reviewed and approved as if it were an original procedure. All reviewers should be consulted early in the process to assure that their concerns are addressed, avoiding the need for later revisions to the procedure.
Each person involved in a high-consequence/high-value lift must be familiar with the procedure before beginning work. A pre-lift meeting with all participating personnel must be held before the lift. All participating personnel must initial the procedure sign-off sheet to verify that they are familiar with the procedure.
The project Construction Manager shall arrange for all reviewers/approvers to be available by phone, e-mail, or fax during the operation should the lift plan need to be modified and reapproved.
LBNL will monitor and review the safety procedures during demolition processes to ensure the safety of all subcontractors. It is the sole responsibility of the subcontractor who conducts these processes to utilize and enforce the following procedures and meet all current DOE, federal, state, and/or local relevant to the operation(s).
The LBNL Project Manager is responsible for developing detailed Utility Isolation Plans on all demolition projects to include drawings of all electrical and mechanical work.
The subcontractor shall be responsible for submitting a Job Hazard Analysis and all other work procedures to the LBNL Project Manager for review and approval a minimum of seven days prior to the start of demolition for each phase.
Prior to permitting employees to start demolition operations, an engineering survey will be made by a qualified person designated by the subcontractor. This survey shall determine the condition of the framing, floors, and walls, and will also determine the possibility of an unplanned collapse of any part of this structure. Adjacent structures will be checked for structural integrity. Written evidence of the results of this survey is to be given to the LBNL Project Manager.
Demolition work shall at all time be under the immediate supervision of a qualified person with the authority to secure maximum safety for employees engaged in demolition work.
The subcontractors will be required to wear durable gloves, eye protection, steel-toe boots with steel shanks, and long sleeved shirts in addition to their standard personal protective equipment when performing selective demolition operations. The subcontractors are solely responsible for this and any other required personal protective equipment.
Prior to beginning demolition operations, the LBNL Project Manager will obtain a site survey identifying the locations of asbestos- and lead-containing materials. The subcontractor shall employ a testing agency that can identify and/or verify areas suspected of containing these materials prior to their disturbance during the demolition operation at the subcontractor’s own cost. The LBNL Project Manager shall be responsible for developing and documenting a detailed utility isolation plan.
All electric, gas, water, steam, sewer, and other service lines shall be shut off, capped, or otherwise controlled outside the building line before demolition work is started.
If electric, gas, water, steam, sewer, or other utilities are necessary during demolition; their lines shall be temporarily relocated and protected.
Before demolition begins, the building will be checked by LBNL management to determine whether any hazardous chemicals, gases, explosives, flammable materials, or similarly dangerous substances have been used in pipes, tanks, or other equipment on the property, if found, such substances will be decontaminated or eliminated before demolition is started. Any hazardous glass fragments shall be removed.
All floor and wall openings, which pose a fall exposure, shall be protected by guardrails and/or covers.
If debris is dropped through holes in the floor without the use of chutes, the area onto which the material is dropped will be completely enclosed with barricades not less than 42 inches high, and not less than 6 feet back from the project openings. Signs shall be posted at each level, warning of the hazard of falling materials. Removal of the debris from the lower area shall not be permitted until debris handling from above has ended.
Floor openings not used as material drops will be covered with material that can withstand the weight of any potential load. The floor-opening cover will be secured to prevent it from being incidentally moved.
Demolition of exterior wall construction and floor construction will begin at the top of the structure and proceed downward, except for the cutting of holes in floors or walls for chutes and material drops, preparation of storage space, and similar preparatory work. Each story of exterior wall and
floor construction will be removed and dropped into the storage space prior to removing exterior walls and floor construction in the story below.
Entrances to multistory structures being demolished shall be completely protected by sidewalk sheds, canopies, or both. Protection shall be provided from the face of the building for a minimum of 8 feet. Canopies shall be at least 2 feet wider (1 foot each side) than the opening or entrance being protected, and will be capable of sustaining a load of 150 pounds per square foot.
Materials, chutes, or sections at an angle of more than 45 degrees from the horizontal will be entirely enclosed, except for openings equipped with closures at or about floor level where materials are inserted. The openings will not exceed 48 inches in height as measured along the wall of the chute. At all stories below the top floor, openings not being used will be kept closed or covered.
Each chute shall have a substantial gate at or near the discharge end. The subcontractors designated Competent Person shall control the operation of the gate and the backing and loading of trucks.
When operations are not in progress, the area surrounding the discharge end of a chute shall be securely closed off.
A standard guardrail will protect any chute opening into which debris is dumped. Any space between the chute and the openings in the floor through which the chute passes will be covered.
Where material is dumped from mechanical equipment or wheelbarrows, a securely attached toe board or bumper not less than 4 inches thick and 6 inches in height will be provided at each chute opening.
There is to be no removal of materials through floor openings unless approved by the LBNL Construction Manager.
Openings cut in floors will extend the full span of the arch between supports. Before demolishing a floor arch, debris and other material will be removed from the arch and other adjacent floor areas. Planks not less than 2 inches by 10 inches in cross section, full-size undressed, will be used to stand on while breaking down floor arches between beams. The planks will be placed so that a safe support is provided for the workers if the arch between the beams collapses. The open space between planks shall not exceed 16 inches.
Safe walkways meeting Federal OSHA standards, not less than 18 inches wide, formed of planks, not less than 2 inches thick, if wood, and of equivalent strength, if metal, will be provided so that workers can reach any point without walking on exposed beams.
Planks will be laid together over solid bearings with the ends overlapping at least 1 foot.
Demolition of floor arches will not be started until the arches and surrounding floor area for a distance of 20 feet have been cleared of debris and any other unnecessary materials.
Mechanical equipment will not be used on floors or working surfaces unless the floor or surface is strong enough to support the imposed load.
No demolition materials are to be stored inside the building without the permission of the LBNL Construction Manager and meeting Cal/OSHA standards.
Steel construction shall be dismantled column length by column length and tier by tier. If cutting and burning is to be done on steel, then the steel must be checked for lead-based paint. If lead is found in the paint, then the proper precautions must be taken to prevent worker exposure. In addition, a fire permit along with a fire watch must be maintained for a minimum of 30 minutes after all cutting and burning has been completed.
When demolition balls and clam buckets are used for demolition, no craft personnel will be allowed to enter an area where they can be adversely affected by this operation. Only those employees necessary for the performance of the operations will be permitted in this area at any other time.
The weight of the demolition ball shall not exceed 50 percent of the crane's rated load, or it will not exceed 25 percent of the nominal breaking strength of the line by which it is suspended, or whichever is less. This is based on the length of the boom and the maximum angle of operation at which the ball will be used.
The ball will be attached to the load line with a swivel-type connection to prevent twisting of the load line, and attached so that the weight cannot become incidentally disconnected.
During demolition, continuing daily inspections by the subcontractor assigned Competent Person shall be made as the work progresses so that hazards that could result from weakened or deteriorated floors, walls, or loosened material are detected. No subcontractor employee will be allowed to work where such hazards exist until these hazards are corrected by shoring, bracing, or other effective means.
Subcontractors are responsible for training their employees in all applicable demolition operations and all applicable DOE, federal, state, and local laws, codes, and standards.
Use of electricity on construction job sites poses serious hazards, such as electrocution, burns, fires, explosions and arc flash/blast. All construction work performed by LBNL employees as well as subcontractors shall comply with applicable local codes/regulations, federal and California state OSHA standards, and other codes/regulations such as, but not limited to, NFPA codes (i.e. National Electrical Code (NFPA 70), NFPA 70E, Standard for Electrical Safety in the Workplace, NFPA 79, Electrical Standard for Industrial Machinery), and the National Electrical Safety Code (ANSI C2). The most current versions and stringent requirements shall always apply. In addition, compliance with all elements of this section and PUB-3000 is required. Requirements specific to electrical are found in PUB-3000, Chapter 8. Electricians and apprentices shall be certified in accordance with California law, and shall carry certification cards.
All 120-volt, single-phase, 15-, 20-, and 30-ampere receptacle outlets that are in use by employees shall be protected by approved GFCIs. Receptacles other than 120-volt, single-phase, 15-, 20-, and 30-ampere receptacles shall be protected by approved GFCIs, or a written assured equipment grounding conductor program shall be continuously enforced at the site by one or more designated persons to ensure that equipment grounding conductors for all cord sets, receptacles that are not a part of the permanent wiring of the building or structure, and equipment connected by cord and plug are installed and maintained properly. The program should conform to the requirements of OSHA Standard 29CFR 1926.404(b)(iii). Workers shall test GFCI receptacles according to the manufacturer’s instructions before each use.
All subcontractors shall have a system in place for routine testing and maintaining of electrical tools, equipment, extension cords, and other electrical equipment. The program shall be in writing, with a copy provided to LBNL Construction Safety Engineer for review.

All electrical equipment (such as saws, hammers, drills, vibrators, and float machines) shall bear the label of a Nationally Recognized Testing Laboratory (NRTL), such as Underwriters Laboratories (UL), CSA, ETL, or the like.
All tools shall be of the grounding type. Cord-connected tools shall be grounded through an approved grounding attachment plug.
Exception: Tools identified as “Double Insulated” are not required to be grounded.
Stationary electric equipment with exposed metal parts like housings, boxes, and hoist frames shall be grounded.
Only heavy-duty cords identified as hard or extra-hard usage (see NEC Table 400.4) (such as types S, ST, SO, STO) are acceptable. Cords shall be maintained in their original designed configuration. Any cord that is damaged or has a grounding pin removed shall be removed from service.
The subcontractor shall remove cords that have been spliced or repaired from project site. There will be no repair or taping of cords in any manner. The gauge of wire of the cord shall be sized for the designated use, but in no case less than 14 gauge. For an overall length over 100 feet, one size larger than required for the connected load shall be used. All extension cords shall be plugged into job-site power that has proper overcurrent and ground-fault protection.
All extension cords shall be kept out of walkways and out of wet conditions on the floor.
Upon installation, repair, or modification of job-site receptacles, the installing subcontractor shall test each receptacle for proper polarity and GFCI operation.
Temporary wiring shall be cable assemblies or multiconductor cords or cables identified for hard usage or extra-hard usage (See NEC Table 400.4). All wiring methods shall suit the conditions and environment where installed. No single conductor cable will be permitted. Temporary wiring shall be removed immediately upon completion of construction or purpose for which the wiring was installed.
Temporary lighting shall not be put on the same circuit as temporary receptacles. A separate lighting circuit for stairways and exit areas is required. The subcontractor(s) installing all wiring and lighting shall be responsible for the maintenance of such materials.
It shall be the responsibility of the subcontractor performing the work to have adjacent overhead electrical lines de-energized, blanketed, or by other means protected from contact by equipment or personnel.
An unqualified worker and the longest conductive object that he or she may contact shall not come closer
to an energized overhead line than the following distances:
50 kV and below….. 10 feet
Over 50kV…………..10 feet plus 4 inches per each 10kV over 50kV
Any qualified electrical worker working within the above clearances shall have a work plan approved by EH&S.
The frame of a portable welding machine operating from an electric power circuit shall be grounded. Switching equipment for shutting down the welding machine shall be provided on or near the welding machine.
The electrode holder and connecting cable shall be fully insulated. Light holders shall not be used for heavy work, and welders shall avoid standing on damp or wet surfaces while welding. All equipment shall be checked regularly to make certain that electrical connections and insulation on the holders and cable are in good order. Cables shall be kept dry and free from oil and grease. They shall be arranged in such a manner that they do not lie in water, oil, or ditches, or on bottoms of tanks. Electrical repairs and maintenance work on welding machines shall be done by a certified electrician. Electric stubs shall be placed in containers provided by the subcontractor for this purpose.
Welders shall be taught to keep welding cables in an orderly fashion and away from places where it could cause a stumbling hazard or become damaged. Where possible, it shall be strung overhead, high enough to permit free passage of vehicles and persons.
PPE requirements are specifically defined by PUB-3000, Chapter 8 and NFPA 70E. Qualified workers who are potentially exposed to electrical hazards that cannot be controlled through some engineering means must be provided with and use personal protective equipment that is appropriate for the specific work to be performed and the associated hazard level. This includes testing, troubleshooting and zero energy verification tasks.
Flame Resistant (FR) apparel used for protection from electrical hazards shall be inspected before each use. Clothing that is contaminated, or damaged to the extent their protective qualities are impaired, shall not be used. Protective items that become contaminated with grease, oil, or flammable liquids or combustible materials shall not be used. The garment manufacturer's instructions for care and maintenance of FR apparel shall be followed.
Rubber-insulating gloves shall be used with leather protectors. The rubber portion of Class 0 and 00 gloves shall extend ½-inch beyond the leather protectors, 1-inch beyond the leather protectors for Class 1 and an additional inch for each higher class. Rubber-insulating gloves shall be dielectrically tested every six months and stamped with the date tested or the date to be tested. Gloves shall be stored in a proper storage bag, as flat as possible (not folded), and shall not be stored with other materials. The qualified person shall inspect and inflate gloves before each use.
Qualified employees shall use insulated tools when working inside the Limited Approach Boundary of exposed live parts where tools or handling equipment might make accidental contact. Workers who are using insulated tools shall inspect them for damage before each use. Insulated tools shall be protected from damage to the insulating material. Insulated tools shall be rated for the voltages on which they are used, shall meet ASTM F1505 requirements, and shall be labeled with the ASTM approval mark. Insulated tools shall be designed and constructed for the environment to which they are exposed and the manner in which they are used.
Test instruments, equipment, and their accessories shall be rated for circuits and equipment to which they will be connected. All test equipment shall be NRTL listed and labeled and shall be Category III or IV rated. Test instruments and equipment and all associated test leads, cables, power cords, probes, and connectors shall be visually inspected for external defects and damage before the equipment is used on any shift. If there is a defect or evidence of damage that might expose an employee to injury, the defective or damaged item shall be removed from service, and not used it until repairs and tests necessary to render the equipment safe have been made.
Any subcontractor performing testing or troubleshooting on exposed live parts greater than 50 volts is required to supplement their safety plan with a Subcontractor Electrical Safety Workbook (PUB-3000, Chapter 8, Appendix B), and an Energized Electrical Work Permit (EEWP) (PUB-3000, Chapter 8, Appendix A).
It is Laboratory policy to prevent the unintended or unexpected startup or release of hazardous energy during servicing, maintenance, or modification activities. No person shall install, service, remove, or perform maintenance on any equipment or machinery that may involve an energy hazard, until that equipment has been de-energized, locked, tagged and verified to be in a zero energy state in accordance with this document.
Subcontractors who work on equipment with hazardous energy source(s) (Electrical, Mechanical, Pneumatic, Chemical, Hydraulic, Water, Steam, Gas) shall have a Lockout/Tagout (LOTO) plan approved by EH&S. The LOTO plan shall comply with 29CFR 1910.147, 29CFR 1910.333 and PUB- 3000, Chapter 18 (Lockout/Tagout and Verification), as a minimum.
This section provides requirements to ensure the safety of all workers who are required to work in and around excavations, and to provide guidelines for obtaining the LBNL Penetration Permit.
The subcontractor shall be responsible for submitting a Job Hazard Analysis and work procedures to the LBNL Project Manager for review and approval a minimum of seven days prior to the start of excavation.
All work that will require excavation or drilling requires an LBNL permit. Permits are required when excavating or drilling will penetrate 1-1/2 inches or deeper from a surface. Subcontractors must obtain the permit through the LBNL Construction Manager a minimum of 10 days prior to the start of work. Work may not proceed unless there is an approved, signed permit at the job or project site. Permits must also be posted in a conspicuous place at the job or project site.
For excavation over 20 feet or deeper, a Registered Professional Engineer hired by the subcontractor shall design all shoring, sloping, or benching. All designs shall be submitted to LBNL Project Manager and filed at the subcontractor's field office prior to the start of work.
Emergency rescue equipment shall be on site and readily available by the subcontractor.
A Competent Person must be identified and assigned by the subcontractor. The Competent Person is responsible for the excavation and shall be on site during all operations relating to the open excavation.
The Competent Person must be capable of identifying existing and predictable hazards in the surroundings, or working conditions that are unsanitary, hazardous, or dangerous to subcontractors. The Competent Person has the authorization to take prompt corrective measures. The Competent Person in charge of the excavation work ensures that:
The Competent Person is responsible for:
The Competent Person responsible for the crew working in the excavation shall inspect the excavation throughout the work period, and stop operations when unsafe conditions exist. The Competent Person shall inspect all excavation before entry:
The Competent Person must be able to identify conditions where hazardous material may exist. The atmosphere in the excavation shall be tested prior to entry and periodically throughout the operation. When conditions change, such as with atmospheric conditions, the Competent Person must immediately remove any persons in harm’s way, and must immediately notify the LBNL Project Manager.
The subcontractor shall evaluate the stability of adjacent structures before starting an excavation, and document and monitor their stability daily thereafter.
Removal of rock or concrete by blasting and pile driving causes vibrations that may be sufficient to damage structures nearby, as may the removal of earth that results in the movement of bracing systems and underpinning, or soil consolidation resulting from the lowering of a water table, etc.
A review of the subsurface conditions (determined from on-site borings) and the plans of existing wildings (where available) are necessary to evaluate lateral and vertical integrity. An inspection to evaluate the condition of adjoining/existing property shall be completed by the subcontractor prior to (and possibly after ceasing) operations.
The following shall influence the degree of inspection:
Where job operations such as pile driving and blasting may cause vibrations affecting the nearby structures, it is required that vibration measurements be made by the subcontractor, making data available to the LBNL Project Manager. This will enable the job to monitor and set up procedures to keep the energy ratio of the vibrations at a safe level.
Where settlement of the nearby street, utilities, and structures may occur because of excavation and foundation work, the streets, utilities, and structures shall be regularly checked for vertical and horizontal movement, and a log maintained by the subcontractor. Any movement shall be investigated immediately.
All inspection reports shall be copied to the LBNL Construction Manager.
Soil classification is a method of categorizing soils and/or rock into categories. Soil classification must be made by the Competent Person or soils engineer. All unclassified soil shall be treated as Type C Soil.
Type C Soil means:
All surface encumbrances that are located so as to create a hazard to subcontractors shall be removed or supported, as necessary, to safeguard workers in the excavation.
This section provides requirements for developing and implementing work controls required for fall protection.
This section is applicable to all fall protection activities covered by PUB-3000 Chapter 30 (Fall Protection Program).
It is the responsibility of the worker to utilize and enforce the following procedures and meet all current DOE, federal, state, and/or Lab policies relevant to the operation(s).
Any work task on a walking/working surface with an unprotected side or edge which is 6 feet or more above a lower level requires fall protection hazard controls. These hazard controls may include: guardrail systems; safety net systems; personal fall arrest systems; or other fall protection measures.
Exception: Work on a flat or low sloped roof (slope less than 4 in 12), where all work is conducted at least 15 feet from any unprotected edge, is permitted to be performed without additional fall protection hazard controls.
Access to roofs and other areas requiring fall protection hazard controls will be identified with a sign that states: “Warning – Fall Protection Required For Work On This Roof – Contact Your Division Safety Coordinator”. The term “Fall Protection” refers to any form of fall protection hazard controls that may include: guardrail systems; safety net systems; personal fall arrest systems; or other fall protection measures.
Any work task on an aerial lift (boom, scissor or one-man lifts) requires fall protection hazard controls when working above the protection system at floor openings, unprotected perimeters greater then 6 feet, and whenever a fall of more than 6 feet could occur.
Exception: Use of a personal fall arrest system is only required on scissor lifts when an engineered anchor point is provided by the manufacturer.
Steel erectors and sheet metal installers are required to utilize 100% positive fall protection above 6 feet at all times
The work control procedure(s) for fall protection for construction and non-construction subcontractors shall be documented on the subcontractor’s approved Job Hazard Analysis. The work control procedure(s) for employee (and subcontractors and guests using LBNL procedures) shall be documented on the LBNL Written Fall Protection Plan (Fall Protection Planning Matrix), provided by the EH&S Division. The LBNL Fall Protection Planning Matrix is a supplement to any existing individual or task specific job hazard analysi
Regardless of the work control procedure(s) used to define the fall protection hazard controls, procedures for rescue shall be detailed on the work control document.
Work tasks excepted from additional fall protection hazard controls:
Horizontal distance (without fall protection) from unprotected edge = 15 ft. minimum, except for roofers.
Free fall distance shall not exceed 6 feet.
Guardrails and parapets must be 39 to 45 inches high, and must withstand 200 lbs at top. Guardrails must have mid-rails and toe-boards, if tools or materials may fall to others below. Cable must be a minimum ¼-in. diameter, and flagged at 6-foot intervals, with no sag under pressure below 39 inches. Pipe must be 1-1/2-inch diameter minimum, and wood must be 2x4 at minimum.
Skylights must be covered with a minimum 200 lb force covers, guardrails, or fall restraint/fall arrest, within a 15-foot distance.
Warning line system (low slope roofs only):
Construction—“Non-Conforming Guardrail,” a minimum of 15 feet from unprotected edge.
Systems requirements — Uprights withstand 16 lb force at 30 inches; line to be rope, wire, chain of 500 lb strength; flagged at 6 ft intervals; height 34–39 inches; line attached to uprights; no slide through.
Fall Restraint — Worker’s center of gravity cannot fall over the unprotected edge in any direction.
Vertical Lifelines shall be a minimum of ¾-inch manila rope or equivalent, secured above the point of operation to anchorage or structural member capable of supporting a minimum of 5,000 lbs. (Only one worker per lifeline.)
Horizontal Lifeline shall be secured above the point of operation to anchorage or structural member capable of supporting a minimum of 5,000 pounds.
Lanyards shall be a minimum of 5/8-inch nylon rope or equivalent with a 900 lb shock-absorbing system and a maximum length to provide for a fall of no longer than 6 feet plus deployed shock absorber. The rope shall have a nominal breaking strength of 5,000 lbs.
Confined spaces are work locations that meet regulatory definitions, and require rigorous additional analysis and work authorization in addition to the usual safe work practices and procedures required by LBNL Integrated Safety Management Systems.
Work control for subcontractors who enter sewers, vaults, pits, excavations, trenches, and other confined spaces will be under the subcontractor’s LBNL approved Permit-required Confined Spaces program as managed by LBNL’s Construction Safety program.
Confined space: a space that
Non-permit Confined Space: a confined space that does not contain or, with respect to atmospheric hazards, have the potential to contain any hazard capable of causing death or serious physical harm.
Permit-required Confined Space: a confined space that has one or more of the following characteristics:
This section applies to all spaces at LBNL which exhibit the characteristics of a confined space, including those classified or not classified as:
Subcontractor entry into confined spaces will be managed under the requirements of Cal/OSHA Title 8, General Industry Safety Orders Article 108, “Confined Spaces” Section 5157 which is authorized for application to the construction industry under the Cal/OSHA Construction Safety Orders. Article 108 is the functional equivalent to 29CFR 1910.146.
PUB-3000, Chapter 34 (Confined Spaces), describes the LBNL Confined Spaces program as implemented by LBNL Construction Safety.
In order to reduce the possibility of fire damage and associated losses incurred during construction, alteration, or demolition, a Fire Safety plan shall be developed to assure that the listed requirements in NFPA 241 (2004 edition), Article 87 of the California Fire Code and the California Code of Regulations (CCR), Title 8, Section 36, Fire Protection and Prevention are addressed. The Fire Safety plan must be submitted to the LBNL Fire Marshal for review and approval. These requirements apply to all projects, subcontractors, and visitors. LBNL employees and their visitors must support the subcontractor’s safety plan, or in the event the work is being done by LBNL, they must support the LBNL safety plan for the construction, alteration, or demolition project.
Prior to commencing work, the following requirements are to be reviewed, and the appropriate measures put in place to assure their compliance.
Each subcontractor is responsible for making sure that their employees are trained in the proper use of fire extinguishers. The subcontractor is responsible for the proper selection, maintenance, and provision of fire extinguishers that provide protection in the area affected by their work. Subcontractors may not rely on the use of LBNL extinguishers in their plan. In no event shall an LBNL extinguisher be moved as part of a plan to protect an area. Extinguisher placement shall follow NFPA 10, latest edition.
In the event of a fire, alert people nearby, activate an alarm, extinguish the fire if safe to do so (avoiding smoke or fumes), and notify management. Listed below is a more detailed list.
Most construction sites have gasoline-powered equipment and thus introduce the hazard of potential fire and dangerous fumes. All welding equipment, generators, and equipment that must be used inside the confines of an enclosed space must be propane or electrical powered unless otherwise approved by LBNL in writing.
Gas engines exhaust carbon dioxide and carbon monoxide. Carbon dioxide is heavier than air; carbon monoxide is slightly lighter. A mixture of the gases usually is heavier than air, although heat may cause it to rise. Both are without color, taste, or smell. Low concentrations cause headache and nausea. Death is swift in high concentrations. A few minutes may be too long. Don't discount this hazard. If anyone exhibits symptoms, do not attempt rescue without proper personal protection equipment.
Do not run gas engines in pits, manholes, or confined spaces without positive ventilation. Always pipe gas engine exhausts to outside air when engine is located in enclosed space. Start blower before engine. If engine stops, be sure space is well blown out before sending anyone in to restart. Always check for CO gas with CO Tester at least once per shift.
Danger spots are deep excavations, pits, manholes, hoist engineers, shanties, pipe or crawl spaces under basement floors, and where gas heaters are used. Treat these spaces as confined spaces.
When drums are used for storage of flammable or combustible liquids, use drum pumps that are designed specifically for flammable or combustible liquids and are listed by a Nationally Recognized Testing Laboratory (NRTL).

Subcontractor employees who are issued hearing protective equipment shall receive training, which includes informing employees of the effects of noise on hearing and the purpose, use and care of hearing protection. This training is the responsibility of the subcontractor.
Warning signs stating "High Noise Area — Hearing Protection required" will be posted by the subcontractor on the periphery of all work areas where subcontractor employees may be exposed to excessive noise levels.
During the course of construction, alteration, or repairs, form and scrap lumber with protruding nails and other debris, shall be kept cleared from work areas, passageways, and stairs in and around buildings or other structures by the subcontractor completing the work on a continuous daily basis.
Combustible scrap and debris shall be removed at regular intervals during the course of construction. Safe means shall be provided to facilitate such removal.
Containers shall be provided for the collection and separation of waste, trash, oily and used rags, and other refuse. Any dumpster in use shall use an "open door" policy or have a proper step platform built up to its side. Containers used for garbage and other oily, flammable, or hazardous wastes, such as caustics, acids, or harmful dusts shall be equipped with covers. Garbage and other waste shall be disposed of daily.
The storage of material shall not create hazards. Bags, bundles, and other containers or materials must be stacked, blocked, interlocked, and limited in height so that they do not slide or collapse. Subcontractor storage areas must be kept free from the accumulation of materials that may cause tripping, fire, or harboring of rats and other pests. Masonry blocks shall not be stacked above 2 pallets, and blocks must be wrapped while stacked.
Subcontractors are solely responsible for the cleanup of their immediate work areas on a daily basis Subcontractors are required to participate in a general cleanup effort on a weekly basis. If a subcontractor fails to complete housekeeping tasks, LBNL management may assign those duties to another subcontractor, and back charge the failing subcontractor for all expenses incurred.
This site will be kept clean at all times!
Ladders shall be inspected daily by the subcontractor's Competent Person. The use of ladders with broken or missing rungs or steps, broken or split rails, or other faulty or defective construction is prohibited. When ladders with such defects are discovered, they shall immediately be withdrawn from service and tagged to prevent use, or destroyed.
Portable ladders shall be used at such a pitch that the horizontal distance from the top support to the foot of the ladder is about one-quarter of the working length of the ladder (the length along the ladder between the foot and the top support). Ladders shall not be used in a horizontal position as platforms, runways or scaffolds.
Extension ladders and side rails shall extend to least 36 inches above the landing. When this is not practical, grab rails, which provide a secure grip for an employee moving to or from the point of access, shall be installed.
Ladders shall not be placed in passageways, doorways, driveways, or any location where they may be displaced by activities being conducted on any other work, unless protected by barricades or guards.
When ascending or descending a ladder, the user shall face the ladder using at least one hand to grasp the ladder. An employee shall not carry an object that could cause the employee to lose balance and fall.

All subcontractors working in certain operations (chemical work, etc.) shall be provided and wear the specialized protection equipment designed for that particular operation. (Wood-soled shoes, non-sparking tools, chemical goggles, etc.) The MSDS shall be consulted regarding protective equipment required.
Falls of workers from, and workers struck by materials falling from, floors and decks of structures during construction are not frequent, but are usually severe. The object of this section is to present the common methods of worker protection in these two loss areas.
Frequently, railings and covers are moved in order for material to be hoisted or to perform other work and then replaced. In either case, procedures and designs to facilitate swift and safe removal and replacement shall be developed during pre-job or pre-operational planning and strict enforcement of those procedures required.
100% positive fall protection is required and must be maintained during the installation and removal of these devices.
The use of metal banding or chains (except when furnished by the manufacturer of the equipment) is prohibited as perimeter or other fall protection.
Floor and roof openings shall be protected by a standard railing or cover. All "skylights" shall be protected in the same manner.
Covers shall support without failure at least twice the weight of the subcontractors, equipment, and materials that may be imposed on the cover at any one time.
All covers shall be secured so as to prevent displacement.
All covers shall be color coded or marked with the words "hole" or "cover.”
Railings shall be constructed of wood, as follows, or in an equally substantial manner from other materials, and shall consist of a top rail not less than 42 inches or more than 45 inches in height measured from the upper surface of the top rail to the floor, platform, runway or ramp level and a mid-rail.
The mid-rail shall be halfway between the top rail and the floor, platform, runway or ramp. "Selected lumber,” free from damage that affects its strength, shall be used for railings constructed of wood.
A standard toe board shall be 4 inches (nominal) minimum in vertical height from its top edge to the level of the floor, platform, runway, or ramp. It shall be securely fastened in place and have not more than ¼-inch clearance above floor level. It may be made of any substantial material, either solid, or with openings not over one inch in greatest dimension. Toe boards shall be provided on all open sides and ends of railed scaffolds at locations where persons are required to work or pass under the scaffold and at all interior floor, roof, and shaft openings.
Toe boards shall be capable of withstanding, without failure, a force of at least 50 pounds applied in any downward or outward direction at any point along the toe board.
For wood railings, the posts shall be at least 2" x 4” stock spaced not more than 8 feet apart. The top rail shall be of 2" x 4" stock, and the intermediate rail shall be at least a one by six-inch board. No double-headed nails are to be used in the construction of these railings.
When wire rope is used for guardrails, the cables shall be 3/8-inch minimum diameter wire rope of 13,500 pounds minimum breaking strength.
Posts shall not be more than 6 feet on center. For cable safety railings, cables shall be looped and triple clamped at the connecting points. Single cables running past each other with one clamp are not acceptable.
AT NO TIME WILL ANY GUARDRAIL BE USED AS A HORIZONTAL ANCHORAGE FOR PERSONAL FALL ARREST EQUIPMENT UNLESS SPECIFICALLY DESIGNED BY AN ENGINEER AND APPROVED BY AN LBNL STRUCTUAL ENGINEER.
During the construction of reinforced concrete buildings, subcontractors erect forms or perform other duties over exposed vertical or upturned reinforcing bars, bolts, or other protrusions (i.e., conduits/pipes). Serious injuries and deaths have resulted from falls on these protrusions. Also, floor slab reinforcing that extends beyond a section of slab in place can be an Incident.
Subcontractors are not permitted to work above vertical protruding reinforcing steel unless it has been protected to eliminate the hazard of impalement.
Several approved methods to protect against this hazard are:
Wire mesh or reinforcing bars extending beyond a section of slab in place shall be bent down and secured to eliminate a tripping hazard. Otherwise, subcontractors shall be prohibited from walking over the area.
Warning, Danger, No Trespassing and other signs, correctly posted, help to protect the public and subcontractor employees from incidents.
Proper signs shall be posted and maintained in good condition wherever hazardous conditions exist by the subcontractor. A sufficient supply of the necessary signs shall be kept on hand for replacement and to cover new hazards as they develop. Additional posting requirements to be completed by the subcontractors are found in the Federal Occupational Safety and Health Act, Construction Standards. Such requirements include but are not limited to posting for lasers, powdered actuated tools, and overhead hazards. (Reference: OSHA 1926.200).
The following rules are required during the erection and use of scaffolds by all subcontractors:
Spray-on Fireproofing Operations can create a number of safety, health, and environmental hazards if not carefully managed.
The hazards from over spray and fallout of spray-on fireproofing may be further aggravated by blowing wind.
The following shall be required to keep potential hazards to a minimum:
When fireproofing is completed in an area or on a floor, the material shall be completely removed from the floor before the over spray protection is removed.
All fireproofing material that has collected on or in the over spray protection shall be completely removed as the protection is removed. No material shall be allowed to fall outside of the building or left on the floor.
Dust created by dumping dried bagged material into the mixer shall be controlled.
Empty bags shall be neatly stacked and tied. No dried material shall be allowed to contaminate the area.
To contain over spray, exteriors shall be enclosed. To avoid disturbing fireproofing on exterior columns and spandrel beams, considerable care shall be taken when removing protection. It is recommended that plastic tarpaulins be used, as the spray fireproofing will not stick to this material.
Special care shall be taken to minimize over spray from the cementations spray-on fireproofing on floors and platforms to avoid causing exceedingly slippery conditions. The subcontractor is solely responsible to keep the spray on fireproofing work area cleaned up on a continuous daily basis.
When operations are such that signs, signals, and barricades do not provide the necessary protection on or adjacent to a highway or street, flagmen, or other appropriate traffic controls shall be provided by the subcontractor completing the operation.
Signaling directions by flagmen shall conform to American National Institute D6.1-I971.
Hand signaling by flagmen shall be by use of red flags at least 18 inches square or sign paddles, and in periods of darkness, red lights. Flagmen shall be provided with and shall wear a red or
orange warning garment while flagging. Warning garments worn at night shall be reflective material.
All subcontractors receiving materials are solely responsible for the traffic control during the unloading processes and shall provide the necessary personnel to complete such tasks. All efforts shall be made to ensure trucks with materials are unloaded on site.
Permits are required for the activities listed below and must be obtained prior to start of work. Permits must be posted conspicuously at the work site.
All hot work requiring the use of open flames, heat-producing, or spark-producing equipment requires a Fire Safety Permit from the LBNL Fire Department. Upon request for a Fire Safety Permit, the Fire Department's representative will meet the requester at the work location and discuss precautions to be taken, including the placement of fire extinguishers or a fire watch.
Construction subcontractors may request a Fire Safety Permit directly from the Fire Department or through the Project Manager.
All work that will require excavating, drilling, or driving stakes or poles 1 5/8 inches or deeper into a surface requires a permit. A permit is also required to penetrate any depth into existing concrete surfaces such as floor slabs, walls, beams, or columns.
The permit is issued by the LBNL Utilities Engineer. Subcontractors may obtain the permit through the Project Manager.
Users must familiarize themselves with and comply with OSHA Standard 29 CFR 1910.178 and 1926 Subpart O. This standard is summarized as follows:
A.26.2 Fire Safety
