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.

4
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.

5
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.

Modules 2,3,4, and 5

• Teaches the greatest good for the greatest number
  of people.
• Necessary goal of disaster recovery.
• Teaches problem-solving skills based on lifelong
  learning.
• Teaches citizens how to be resourceful.

CERT Size-Up
10
Size-up

• Starts before the incident.
• Fact gathering mission.
• Assess situation.
• Use the Acronym A.P.I.E.

11
A.P.I.E.

• Analyze the situation.
• Plan the action.
• Implement the plan.
• Evaluate your progress.

12
Fire Chemistry

• How do fires start and what keeps them burning?

13
Fire Chemistry

• Fuel
• Heat
• Oxygen

Hazardous Materials Recognition

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

22
Safe Home Storage Procedures

• L.I.E.S.
• Limit the amount of hazardous material
• Isolate hazardous products
• Eliminate products
• Separate incompatible materials

23
Hazards at Home

• Natural gas hazards
• Non-toxic but may displace oxygen causing
  asphyxiation
• Explosive
• Lighter than air

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

25
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
