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.

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
