Emergencies and Panic
“Do not panic!” That’s easy to say but hard to do during an emergency. A good policy to prepare for emergencies is to simulate the event and practice what should be done. If you have never used a hand-held fire extinguisher in an emergency, is the time to learn when a fire erupts? Certainly not! Practice and planning will help eliminate panic.
