1 Contra Costa County CERT Program Unit 2 Fire Safety Released: 15 September 2016 Community Emergency Response Team Personal safety is ALWAYS the number one priority Work as a team Wear personal protective equipment gloves, helmet, goggles, N95 mask and boots The CERT goal is to do the Greatest Good for the Greatest Number Hope for the best but plan for the worst Visual 2.1 Unit Objectives Explain the role of CERTs in fire safety Identify and reduce potential fire risks in the home and workplace Understand gas and electric utilities Identify hazardous materials in the home and community Understand basic safety precautions Describe CERT fire size-up process Conduct a basic size-up for a fire emergency Extinguish small fires using a fire extinguisher Visual 2.2 Rev. 15 September

2 Role of CERTs CERTs play very important role in fire safety by: Extinguishing small fires Preventing additional fires by removing fuel sources Shutting off utilities Assisting with evacuations when necessary Visual 2.3 Basic Fire Chemistry Fire safety, at its most basic, is based upon the principle of keeping fuel sources and ignition sources separate Visual 2.4 Three things must be present at the same time to produce fire: 1. Oxygen to sustain combustion 2. Heat to reach ignition temperature 3. Fuel or combustible material Together, they produce the chemical reaction that is fire. Take away any of these things and the fire will be extinguished. The Fire Triangle Visual 2.5 Rev. 15 September

Stay away from it. Don t poke it, look at it the wrong way or insult it. Report your finding and let professionals handle the rest. Visual 2.26 Rev. 15 September

16 CERT Fire Size-up Helps responders decide: Whether to attempt to suppress a fire A plan of action Answers these questions: Do my buddy and I have the right equipment? Are there other hazards? Is the building structurally damaged? Can my buddy and I escape? Can my buddy and I fight the fire safely? Remember: The safety of individual CERT members is always the top priority Visual 2.45 CERT Fire Size-up Checklist Step 1: Gather Facts Does the time of day or week impact fire suppression? Will weather conditions impact your safety? Will weather conditions affect the fire situation? What type of structure is involved? What type of construction is involved? Is the structure occupied? Are there special considerations? Are there hazardous materials involved? Are any other hazards likely to be involved? Visual 2.46 CERT Fire Size-up Checklist Step 2: Assess and Communicate the Damage Do a 360 o Are normal communication channels functioning? Step 3: Consider Probabilities Are there potential life-threatening hazards? Does the fire s path jeopardize other areas? Is there a high potential for more disaster activity that will impact personal safety? Visual 2.47 Rev. 15 September

17 CERT Fire Size-up Checklist Step 4: Assess Your Own Situation What resources are available with which you can suppress the fire? What equipment is available? Step 5: Establish Priorities Can fire suppression be safely attempted by CERT? Are there other, more pressing needs at the moment? Visual 2.48 CERT Fire Size-up Checklist Step 6: Make Decisions Where will deployment of available resources do the most good while maintaining an adaquate margin of safety?
