1 Visual 2.1 Introduction and Unit Overview The role of CERTs in fire safety:  Put out small fires.  Prevent additional fires.  Shutoff utilities  Assist with evacuations where necessary.

2 Visual 2.2 Unit Objectives  Explain the role of CERTs in fire safety.  Identify and reduce potential fire risks in the home and workplace.  Conduct a basic sizeup for a fire emergency.  Understand basic safety precautions.  Identify hazardous materials in the home and community.  Extinguish small fires using a fire extinguisher.

3 Visual 2.3 The Fire Triangle  Heat  Fuel  Oxygen

4 Visual 2.4 Fire Chemistry Classes of fire:  A: Ordinary combustibles  B: Flammable and combustible liquids  C: Energized electrical equipment  D: Combustible metals

5 Visual 2.5 Reducing Fire Hazards in Home and Workplace  Avoid the “electrical octopus.”  Don’t run cords under carpets.  Replace broken or frayed cords.  Maintain appliances.

6 Visual 2.6 Reducing Fire Hazards in Home and Workplace  Install a natural gas detector.  Locate and label gas shutoffs.

7 Visual 2.7 Reducing Fire Hazards in Home and Workplace  Read labels.  Use L.I.E.S. storage procedures (Limit, Isolate, Eliminate, Separate).

8 Visual 2.8 CERT sizeup Answer these questions:  Can my buddy and I fight the fire safely?  Do we have the right equipment?  Are there other hazards?  Is the building structurally damaged?  Can we escape?

9 Visual 2.9 CERT Sizeup 1.Gather Facts. 2.Assess Damage. 3.Consider Probabilities. 4.Assess Your Situation. 5.Establish Priorities. 6.Make Decisions. 7.Develop Plans of Action. 8.Take Action. 9.Evaluate Progress.

10 Visual 2.10 Firefighting Resources Resources available:  Portable fire extinguishers  Wet standpipes  Confinement  “Creative” resources

11 Visual 2.11 Types of Fire Extinguishers  Water  Dry chemical  Carbon dioxide  Specialized fire extinguisher

12 Visual 2.12 Hose Gage Label & Directions Pull Pin Trigger Cylinder ABC Carrying Handle

13 Visual 2.13 Types A B C D Fire Type Extinguishing AGENTMETHOD Water Foam Dry Chem. FOAM/CO2 Dry Chem./ Halon Special Agents Removes air & heat Breaks Chain Reaction Removes air Breaks Chain Reaction Usually removes air

14 Visual 2.14 Deciding to use a Fire Extinguisher Ask these Questions  Can I escape quickly and safely from the area if I attempt to extinguish the fire? (The first priority for you and your buddy is safety.)  Do I have the right type of extinguisher?  Is the extinguisher large enough for the fire?  Is the area free from other dangers, such as hazardous materials and falling debris?

15 Visual 2.15 P.A.S.S Test the extinguisher before approaching any fire. P.A.S.S. PULL AIM SQUEEZE SWEEP

16 Visual 2.16 Fire Suppression Safety Do:  Use safety equipment.  Work in a buddy system.  Have a backup team.  Have two ways to exit.  Maintain a safe distance.  Overhaul the fire.

17 Visual 2.17 Fire Suppression Safety DON’T  Try to suppress large fires.  Get too close.  Fight it alone.  Enter smoke-filled areas.

18 Visual 2.18

19 Visual 2.19 Hazardous Materials...  Corrode other materials  Explode or are easily ignited  React strongly with water  Are unstable when exposed to heat or shock  Are toxic to humans, animals, or the environment

20 Visual 2.20 Identifying Stored Hazardous Materials

21 Visual 2.21 Identifying Stored Hazardous Materials NFPA 704 Diamond-White Quadrant: W Shows unusual reactivity with water OX Possesses oxidizing properties Avoid use of water WHITE REACTIVE 4 May detonate -- Vacate area if materials are ex- posed to fire 3 Strong shock or heat may detonate--Use monitors from behind explosion resistant barriers 2 Violent chemical change possible-- Use hose streams from distance 1 Unstable if heated -- Use normal precautions 0 Normally stable FLAMMABLE 2 Ignites when moder- ately heated 1 Must be preheat- ed to burn 0 Will not burn 4 Extremely flammable 3 Ignites at normal temper- atures HEALTH 4 Too dangerous to enter vapor or liquid 3 Extremely dangerous-- Use full protective clothing 2 Hazardous--Use breathing apparatus 1 Slightly hazardous 0 Like ordinary material W
