In case of fire, explosion, medical emergency, gas leak, or chemical or radioactive emergency, call immediately for help. On the main Laboratory site, know as "the Hill," call extension 7911.

For "off-Hill" emergency phone numbers, see this reference list. Give all information requested by the dispatcher.

An injured person should not be moved by personnel unskilled in first-aid treatment unless such action is necessary to save the victim from other serious injury such as a chemical exposure. Stop any serious bleeding and, if you are trained and it is appropriate, administer CPR immediately, before the arrival of emergency personnel.

Evacuate personnel and notify your supervisor or line management immediately.
