Disaster Fire Suppression 3

Module 2 - Fire Suppression, Utility Control and Safety Fire suppression is the topic in Class 2. Fire chemistry, fire extinguisher use,

utility control, ventilation, creative fire fighting techniques, and hazardous materials placarding systems are reviewed and/or practiced.

Module 2 - Points for the Instructor Disaster fire suppression stresses safety

considerations, such as working in the buddy system, and back-up teams are introduced.

It is imperative to stress safety by setting the proper example during tabletop demonstrations, and most importantly during the actual fire extinguishing portion of the class.

Module 2 -Methodology

The lesson uses a PowerPoint slide presentation and overhead transparencies, as well as a classroom tabletop demonstration of fire characteristics.

Participants will also apply what they learned about portable fire extinguishers by extinguishing a flammable liquid fire.

Hazardous Materials Recognition Before Beginning to

fight fires, CERT members must understand how the abundance of hazardous materials will effect the post disaster environment.

Disaster Fire Suppression 22

Safe Home Storage Procedures

L.I.E.S.– Limit the amount of

hazardous material– Isolate hazardous

products– Eliminate products– Separate

incompatible materials

HAZARD

Disaster Fire Suppression 23

Hazards at Home

Natural gas hazards– Non-toxic but may

displace oxygen causing asphyxiation

– Explosive– Lighter than air

GASOLINE

GA

Disaster Fire Suppression 24

Hazards at Home

Propane gas hazards– BBQ grills, Hot tubs,

and heating– Heavier than air and

will seek out a source of ignition

– Will displace oxygen in an enclosed room causing asphyxiation

Warning Placards NFPA 704 Placard System

– 0 - No special hazard– 1 - Nuisance hazard– 2 - Can be fought with standard firefighting

procedures– 3 - Extremely hazardous situation

– 4 - Too dangerous to approach
