COURSE TITLE:FIRE EXTINGUISHER SAFETY AWARENESS (Cont.)

Fire training ground – Duration- 2 hours After asking permission from U&O to utilize the fire training

ground, the Fire Technician will: Connect the 1.5”x100 ft hose line with nozzle from the fire

hydrants as stand by. Fill drip pan size 1.5 sq/m by 6” high with 1/3 water &1/3 fuel

(gasoline). Ignite the fuel using 8 ft long torch. The instructor will demonstrate how to properly operate and

safely use the fire extinguisher (ABC cartridge type) in extinguishing the fire.

Each participant will practically demonstrate, suppressing the fire using the fire extinguisher.

Brief discussion about the used of fire extinguisher( inside classroom).

Fill up course evaluation form ( attached). Training completed / keep record of attendance.

Firefighting Decision Criteria• KnowKnow department emergency procedures

and evacuation routes.• KnowKnow locations of extinguishers in your

area and how to use them.• AlwaysAlways sound the alarm regardlessregardless of

fire size.• AvoidAvoid smoky conditions.• EnsureEnsure area is evacuated.• Don’tDon’t attempt to fight unless:

- Alarm is sounded. - Fire is small and contained. - You have safe egress route (can be reached without exposure to fire). - Available extinguishers are rated for size and type of fire.

• If in doubt, evacuate!evacuate!
