|

|
Introduce Unit
|
|
Introduce this unit by welcoming the participants to Unit 2 of the CERT
training program.
Introduce any new instructors who will be assisting with this session.
Introduce fire safety by telling the participants that during and
immediately following a severe emergency, the first priorities of
professional fire services are life safety and extinguishing major
fires. They may be hampered by impassable roads, inadequate water supply,
weather conditions, burning material, and inadequate resources.

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.
Visual 2.1 |
|
|
|
|
|
Emphasize that CERTs play a very important role in fire safety by:
§
Extinguishing small fires before they become major fires. This unit will provide
training on how to use an extinguisher to put out small fires—and how to
recognize when a fire is too big to handle.
§
Preventing additional fires by removing fuel sources.
This unit will also describe how to ensure that a fire, once extinguished,
is completely extinguished and stays extinguished.
|
| |
|
|
|
|
|
|
|
Introduction and Unit
Overview (Continued)
|
|
|
§
Shutting off utilities, when necessary and safe to do so.
§
Assisting with evacuations where necessary. When a fire is beyond the ability of
CERTs to extinguish, CERT members need to protect life safety by evacuating
the area, when necessary, and establishing a perimeter.
|
Instructor’s Note
|
|
|
Although CERTs assist with evacuations, the
procedures for conducting evacuations are not covered in this course. It is
recommended that evacuation be covered in supplemental training. |
|
|
|
Stress the important role that CERTs play in neighborhood and workplace fire
safety. CERT members help in fire-related emergencies when professional
responders (paid and volunteer) are delayed. When responding, CERT members
should keep in mind the following CERT standards:
§
Rescuer safety is always the number one priority. Therefore,
CERT members always:
·
Work with a buddy.
·
Wear safety equipment (gloves, helmet, goggles, mask, and boots).
§
The CERT goal is to do the greatest good for the greatest number.

Fuel
§
Oxygen
Visual 2.3 |
|
|
|
|
If not
mentioned by the participants, explain that fire requires three elements to
exist:
§
Heat: Heat is required to elevate the
temperature of a material to its ignition point.
§
Fuel: The fuel for a fire may be a solid,
liquid, or gas. The type and quantity of the fuel will determine which
method should be used to extinguish the fire.
§
Oxygen: Most fires will burn vigorously in any
atmosphere of at least 20 percent oxygen. Without oxygen, most fuels could
be heated until entirely vaporized, yet would not burn.
|
| |
|
|
|
|
|
|
|
|
|
|
Fire Chemistry
(Continued)
|
|
|
|
Explain that working together, these three elements, called the fire
triangle, create a chemical exothermic reaction, which is fire.
|

|
PM, P. 2-3
|
|
Refer the participants to the Fire Triangle figure in the Participant
Manual.
Stress that if any of these elements is missing or if any is taken
away, fire will not occur or will extinguish.
|
|
|
|
Tell the
group that you will now demonstrate the concept of the fire triangle by
removing the oxygen from burning cotton.
|
|

|
Instructor’s Note
|
|
|
Use the following steps to demonstrate the concept:
1.
Ignite a
rolled-up piece of cotton, place it inside a Pyrex® jar, and
cover it tightly.
2.
Wait
until the flame goes out.
3.
Remove
the material from the jar and blow on it to demonstrate that, unless the
fire is completely out and overhauled, adding oxygen may complete the fire
triangle and rekindle the fire.
Emphasize the need to ensure that every piece of
burning material is completely extinguished. Tell the participants to think
of Smokey the Bear and campfires to remember this point. |

|
Fire Chemistry
(Continued)
|
|
|
|
Tell
the participants that, to aid in extinguishing fires, fires are categorized
into classes based on the type of fuel that is burning:
§
Class A Fires: Ordinary combustibles such as paper,
cloth, wood, rubber, and many plastics.
|
|

|
Instructor’s Note
|
|
|
Reemphasize the need to overhaul Class A fires (i.e.,
ensure that every piece of burning material is completely
extinguished). |
|
|
|
|
|
|
|
|
§
Class B Fires: Flammable liquids (e.g., oils,
gasoline) and combustible liquids (e.g., charcoal lighter fluid, kerosene).
These fuels burn only at the surface because oxygen cannot penetrate the
depth of the fluid. Only the vapor burns when ignited.
§
Class C Fires: Energized electrical equipment (e.g.,
wiring, motors). (When the electricity is turned off, the fire becomes a
class A fire.)
§
Class D Fires: Combustible metals (e.g., aluminum,
magnesium, titanium).
Stress
that it is extremely important to identify the type of fuel feeding
the fire to select the correct method and agent for extinguishing the fire.
|
|

|
Instructor’s Note
|
|
|
Ask the group if anyone has any questions about fire
chemistry. |
|
|
|

|
|
Reducing Fire Hazards
in the Home and Workplace
|

|
Introduce Topic
|
|
Explain that this section will deal with identifying and preventing fire
hazards in the home and workplace.
Introduce
this topic by asking the following question:
|
|

|
Ask Question
|
|
|
What are potential fire hazards in homes or workplaces? |
|
|
|
|
Allow the
group time to respond. Provide suggestions of additional potential fire
hazards.
|
|
|
|
Emphasize that part of CERT planning is to identify hazards in the area that
would affect them in an emergency. This information is important to
professional responders when they arrive on scene.
|
|

|
Ask Question
|
|
|
What measures have you taken to mitigate or prevent the hazards? |
|
|
|
|
Use the participants’
responses to make the following points:
§
Each of us has some type of fire hazard in our home or workplace.
Most of these hazards fall into three categories:
·
Electrical hazards
·
Natural gas hazards
·
Flammable or combustible liquids
|
|
|
|
Point out that homes and workplaces can and do have other hazards, including
incompatible materials stored in close proximity to each other.
|
|
|
|
§
Simple fire prevention measures will go far in reducing the
likelihood of fires:
·
First, locate potential sources of ignition.
 |
Then, do what you can to reduce or eliminate the hazards. |

|
|
|
|
|
|
|
|
Reducing Fire Hazards
in the Home and Workplace (Continued)
|
|
|
|
Point out that emergencies sometimes occur despite our best efforts. In the
event of an electrical emergency:
§
Know where the power shutoffs for electrical appliances are.
§
Know where the power shutoff for circuit breakers or fuses is and how
to shut off the power.
§
Unscrew individual fuses or switch off smaller breakers first, then
pull the main switch or breaker.
§
When turning the power back on, turn on the main switch or breaker
first, then screw in the fuses or switch on the smaller breakers.
|
|
|
|
Stress that the participants should not enter a flooded basement to
shut off the electrical supply because water conducts electricity.
|

|
PM, P. 2-6
|
|
Refer the participants to the figures, Circuit Box and Fuse Box in
the Participant Manual.
|
|

|
Instructor’s Note
|
|
|
Check with a representative from the local utility company regarding
local utility protocols, and convey these to the participants. If possible,
develop training models of fuse and breaker boxes to allow demonstrations
and hands-on practice. Depending on your location, you may also choose to
cover propane gas shutoffs. |

Reducing Fire Hazards
in the Home and Workplace (Continued)
|
|
|
|
|
Stress that in a disaster, if they smell gas, see the indicator on the meter
showing gas is flowing, or if there is a fire, the participants should turn
off the meter from outside the building. After service is turned off,
however, it can be restored only by a trained technician.
|
|

|
Instructor’s Note
|
|
|
Again, consult with a local utility representative to determine
protocols and, if possible, create a model gas meter to demonstrate and
allow practice with the procedure for shutting off the gas. |

of one during the training. |
|
|
|
|
Point out
that there are also other firefighting resources available that are less
common:
§
In interior spaces, it is possible to confine a fire and
restrict the spread of smoke and heat by closing doors to rooms and
hallways.
§
Other creative resources may also be available:
·
Swimming pool or spa water and buckets
·
Sand or dirt and shovels
·
A garden hose
Emphasize that the type
of fuel that is burning will determine which resources to select to fight a
fire.
Add
that, because portable fire extinguishers are most common, this section will
focus on them.

|
Extinguisher Rating
and Labeling
|
|
|
|
|
Tell
the group that portable fire extinguishers must be rated and approved by the
State Fire Marshal and Underwriters Laboratories. They are rated according
to their effectiveness on the different classes of fire. Their strength and
capability must also be labeled by the manufacturer.
Explain that the label contains vital information about the type(s) of fire
for which the extinguisher is appropriate.

Tell the
participants that there are a series of questions that they should ask
themselves before attempting to fight a fire with a fire extinguisher.
Stress
that if the participants answer “NO” to any of these questions, they
should:
§
Leave the building immediately.
§
Shut all doors as they leave to slow the spread of
the fire.
Tell
the participants that if they answer “YES” to all of these questions,
they may attempt to extinguish the fire. Emphasize that even if they answer
“YES” to all of the questions, but feel unable to extinguish the fire, they
should leave immediately.

Refer the
group to the chart, titled Deciding to Use a Fire Extinguisher, in
the Participant Manual, and review the decisions with the group:
§
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?

Can I escape
quickly and safely if I attempt to extinguish the fire?
§
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 fallen debris?
If
the answer to all questions are “yes,” CERT members should attempt to
extinguish the fire. If the answer to any questions are “no,” CERT
members should leave.

Fire Suppression
Safety
|
|

|
Introduce Topic
|
|
Introduce this topic by reminding the participants that, as CERT members,
fire suppression will be one of their roles. Emphasize however, that—even
following a disaster—their personal safety must be their number one
concern. Stress that they will be unable to help anyone if they are injured
through careless sizeup or unsafe acts.
|

|
PM, P. 2-22 & 2-23
|
|
Refer the group to the list of Fire Suppression Safety Rules in the
Participant Manual.
|

|
PM, PP. 2-22 & 2-23
|
Fire Suppression Safety
Rules |
|
Fire
suppression safety rules include:
§
Use safety equipment at all times. Wear your helmet, goggles, dust mask,
leather gloves, and heavy shoes. If you are not equipped to protect your
personal safety, leave the building.
§
Work with a buddy. Buddies serve an important purpose. They protect your
safety. Don’t ever try to fight a fire alone.
§
Have a backup team, whenever possible.
A backup team just makes good sense. A backup team can support your fire
suppression efforts and can provide help if you need it.
|
|
§
Always have two ways to exit the fire area.
Fires spread much faster than you might think. Always have a backup escape
plan in case your main escape route becomes blocked.
§
Feel closed doors with the back of the hand,
working from the bottom of the door up. Do not touch the door handle
before feeling the door. If the door is hot, there is fire behind it. Do
not enter! Opening the door will feed additional oxygen to the fire.
§
Confine the fire, whenever possible, by keeping doors closed.
§
Stay low to the ground. Smoke will naturally rise. Keeping low to the ground
will provide you with fresher air to breathe.
|
|
§
Maintain a safe distance. Remember the effective range of your fire
extinguisher. Don’t get closer than necessary to extinguish the fire.
§
Overhaul the fire to be sure that it is extinguished—and stays
extinguished.
|
|
What
CERTs don’t do when suppressing fires is as important as what they
should do. DON’T:
§
Get too close. Stay near the outer range of your extinguisher. If you feel the
heat, you are too close.
§
Try to fight a fire alone. Remember that your first priority is your personal
safety. Don’t put yourself at risk.
§
Try to suppress large fires. Learn the capability of your equipment, and do not try
to suppress a fire that is clearly too large for the equipment at hand
(i.e., a fire that is larger than the combined ratings of available fire
extinguishers).
§
Enter smoke-filled areas. Fire suppression in smoke-filled areas requires
equipment that CERTs don’t have. |

§
Enter smoke-filled areas. Suppressing fires in smoke-filled areas requires
equipment that CERTs don’t have.
Explain that portable
extinguishers are rated for the size of fire that they can handle. This
rating is expressed as a number from 1 to 40 for Class A extinguishers and
from 1 to 640 for Class B extinguishers. This rating will appear on the
label–2A:10B:C, for example. The larger the numbers, the larger the fire of
a specific class on which the extinguisher can be used. (Note that
higher-rated models are often heavier. Make sure you can hold and operate
an extinguisher before you buy it.)
No number accompanies an
extinguisher rated Class C. The C on the label indicates only that the
extinguisher is safe to use on electrical fires.
Extinguishers for Class D
fires must match the type of metal that is burning. These extinguishers
also do not use numerical ratings. Extinguishers for Class D fires are
labeled with a list detailing the metals that match the unit’s extinguishing
agent.

|

|
Instructor’s Notes
|
|

explain that a small fire:
§
Is about
the size of a wastepaper can.
§
Can be
