engine. When an automobile engine has a gas/air mixture that is below
the LFL, the engine will not start because the mixture is too lean. When
the same engine has a gas/air mixture that is above the UFL, it will
not start because the mixture is too rich (engine is flooded). When the
gas/air mixture is between the LFL and UFL levels, the engine should
start.
Fire experts advise that the best way to reduce the possibility of
fire in the workplace is through prevention. The plant safety person
has an important responsibility in fire prevention. In the first place,
the plant safety person must ensure that workers are trained in fire
prevention practices. Second, workplace housekeeping practices must
be monitored and strongly enforced. If workers allow debris or flam-
mable material to accumulate and supervisors do not correct this prac-
tice, the risk of fire increases. The plant safety person and work center
supervisors must ensure that all workers understand that fire preven-
tion is everyone's job. Because of the deadly nature of fire, it is to all
workers' benefit to know how to size up a fire and how to respond in a
fire emergency.
1.13.8.1 Fire Prevention and Control
Fire prevention and control measures are taken
before
fires start.
Fire prevention and control are best accomplished by:
•
Eliminating heat and ignition sources
•
Separating incompatible materials
•
Having available adequate means of fire fighting (e.g., sprinklers,
extinguishers, hoses)
•
Proper construction and choices of storage containers
•
Proper ventilation systems for venting and reducing vapor buildup
In the event of a fire emergency, unobstructed means of egress for work-
ers must be provided. Additionally, adequate aisle and fire-lane clear-
ance for firefighters and equipment must be maintained.
All workers need to know what to do in the case of a fire emergency;
they need a plan. The fire emergency plan normally is the protocol to fol-
low for fire emergency response and evacuation. The plant safety person
is usually charged with the responsibility for developing fire prevention
and emergency response plans that spell out everyone's role. Make your
fire plan as easy as possible. Along with an easily understood fire plan,
the workers need to know what actions they are expected to take in the
event of a fire.
Keep in mind that in addition to some type of fire emergency
response action plan, each plant needs to have a well thought out fire
emergency evacuation plan.
