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 Disaster
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.

Safe Home Storage Procedures

L.I.E.S.
– Limit the amount of
hazardous material
– Isolate hazardous
products
– Eliminate products
– Separate
incompatible
materials

HAZARD
22
Hazards at Home

Natural gas hazards
– Non-toxic but may
displace oxygen
causing asphyxiation
– Explosive
– Lighter than air
GASOLINE
GA
Disaster Fire Suppression
23
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
