I work in a Hospital, and we use the following, in varying situations:
In the event of a fire, R-A-C-E
Rescue - anyone in immediate danger
Alarm - pull the alarm box
Contain - close windows and doors
Evacuate - to the next "smoke zone"
To operate a fire extinguisher, P-A-S-S
Pull - the pin
Aim - at the base of the fire
Squeeze - the trigger handle
Sway - the stream back and forth
And a new one I'm really not happy with,
In the event of a hazardous spill, C-L-E-A-N
Contain - the spill
Leave - the area
Emergency - medical treatment
Access - the MSDS (Material Safety Data Sheet)
Notify - contact the operator
Happy Diving,
