Have them check on each other and their immediate area and report any injuries or building damage. ECs tell trained people to give any needed first aid. Do not call 911 for injuries that do not really need their response. It is usually safer to remain inside if the building appears sound, the weather is bad, and the fire alarm is not sounding. Evacuate with special care when a fire alarm starts during a quake.
Earthquakes can set off fire alarms.
Assure that the route is safe for evacuation. If the alarm is not sounding, report to the SEC the condition of your area. SEC and ECs then quickly concur on whether evacuation is needed. When in doubt, evacuate. Do not re-enter until facilities personnel or the SEC and ECs verify that there is no evidence of structural damage.
