A fire is the most common type of emergency for which
small businesses must plan. A critical decision when
planning is whether or not employees should fight a small
fire with a portable fire extinguisher or simply evacuate.
Small fires can often be put out quickly by a well-trained
employee with a portable fire extinguisher. However, to do
this safely, the employee must understand the use and
limitation of a portable fire extinguisher and the hazards
associated with fighting fires. Evacuation plans that
designate or require some or all of the employees to fight
fires with portable fire extinguishers increase the level
of complexity of the plan and the level of training that
must be provided employees. |

Should
employees evacuate or be prepared to
fight a small fire? |
Choosing to evacuate the workplace
rather than providing fire extinguishers for employee
use in fighting fires will most effectively minimize
the potential for fire-related injuries to employees.
In addition, training employees to use
fire extinguishers and maintaining them requires
considerable resources. However, other factors,
such as the availability of a public fire department
or the vulnerability of
egress routes, will enter into this decision.

Risk
assessment |
Portable
fire extinguishers have two functions: to control
or extinguish small or incipient stage fires and
to protect evacuation routes that a fire may block
directly or indirectly with smoke or burning/smoldering
materials.
To extinguish a fire with a portable extinguisher,
a person must have immediate access to the extinguisher,
know how to actuate the unit, and know how to apply
the agent effectively. Attempting to extinguish
even a small fire carries some risk. Fires can increase
in size and intensity in seconds, blocking the exit
path of the fire fighter and creating a hazardous
atmosphere. In addition, portable fire extinguishers
contain a limited amount of extinguishing agent
and can be discharged in a matter of seconds. Therefore,
individuals should attempt to fight only very small
or incipient stage fires.
Prior to fighting any fire with a portable fire
extinguisher you must perform a risk assessment
that evaluates the fire size, the fire fighters
evacuation path, and the atmosphere in the vicinity
of the fire.
Risk
Assessment Question |
Characteristics
of incipient stage fires or fires that can
be extinguished with portable fire extinguishers |
Characteristics
of fires that SHOULD NOT be fought with a
portable fire extinguisher (beyond incipient
stage) - evacuate immediately |
Is
the fire too big? |
The
fire is limited to the original material ignited,
it is contained (such as in a waste basket)
and has not spread to other materials. The
flames are no higher than the firefighter's
head. |
The
fire involves flammable solvents, has spread
over more than 60 square feet, is partially
hidden behind a wall or ceiling, or can not
be reached from a standing position. |
Is
the air safe to breathe? |
The
fire has not depleted the oxygen in the room
and is producing only small quantities of
toxic gases. No respiratory protection equipment
is required. |
Due
to smoke and products of combustion, the fire
can not be fought without respiratory protection. |
Is
the environment too hot or smoky? |
Heat
is being generated, but the room temperature
is only slightly increased. Smoke may be accumulating
on the ceiling, but visibility is good. No
special personal protective equipment is required. |
The
radiated heat is easily felt on exposed skin
making it difficult to approach within 10-15
feet of the fire (or the effective range of
the extinguisher). One must crawl on the floor
due to heat or smoke. Smoke is quickly filling
the room, decreasing visibility. |
Is
there a safe evacuation path? |
There
is a clear evacuation path that is behind
you as you fight the fire. |
The
fire is not contained, and fire, heat, or
smoke may block the evacuation path. |
