Fire Safety
OSHA
requirements for workplace fire safety include exits, emergency
escape routes, fire extinguishers, and emergency plans.
In
September 1991, 25 people died as a result of a fire in the Imperial
Food Products, Inc., plant in Hamlet, North Carolina.
The
cause of the fire was the ignition of hydraulic oil from a ruptured
line only a few feet from a natural-gas-fired cooker. The cooker
was used to cook chicken pieces for distribution to restaurants.
Out
of 90 employees on the shift, 25 died and an additional 54 were
injured.
Many
OSHA violations were uncovered after the fire. The basic OSHA
exit and fire safety violations that contributed to the deaths
and injuries were: [View

- Locked
doors,
- No
marking of exits or non-exits,
- Excessive
travel distances to exits,
- No
fire alarms,
- Obstructed
doors,
- No
emergency action plan or fire prevention plan, and
- No
automatic fire suppression plan.
The
tragic Hamlet fire received a lot of publicity. In spite of this
publicity, blocked exits continue to be found in poultry processing
facilities. OSHA cited a plant in Hudson,
Missouri, for blocking fire and emergency exits in July 1997.
OSHA
standards require:
- Proper
fire exits and training of employees to prevent fire deaths and
injuries in the workplace.
- If
employers want employees to fight small fires, appropriate fire
extinguishers must be available and employees must be trained
to use them.
- If
employees are to evacuate instead of fighting small fires, an employer
must have a written emergency plan and train employees for evacuation.
During a 1997 survey, OSHA found that many facilities had written
emergency plans. However, workers had not received adequate training
or drills in what to do in an emergency.
The basic OSHA requirements for fire exits are:
- There must be at least 2 doors or other means of escape for fire emergencies;
they may not be close to each other.
- Fire doors must not be locked or blocked from the inside when employees
are in the building.
- Routes to the fire exits must be free of obstructions and properly
marked with exit signs.
If an employer wants employees to fight small fires, the proper
types of fire extinguishers must be available. Extinguishers must
be:
- Approved for the types of fire hazards in the plant,
- Maintained, and
- Inspected.
Employees who will use fire extinguishers must be trained:
- About the hazards of fighting fire,
- How to operate the fire extinguishers, and
- How to alert other employees to the fire emergency.
If employees are to evacuate instead of fighting small fires,
an employer must have a written emergency plan.
Emergency action plans:
- Designate evacuation routes and procedures to account for all evacuated
employees;
- Assign responsibilities for procedures to shut down critical operations
and perform rescue and medical duties;
- Establish a way to alert employees to the fire emergency; this may be
voice communication, bells, whistles, or horns; and
- Identify persons who can provide more information.
Employees
must be trained so they know the evacuation signal and what
to do in an emergency.
A
fire prevention plan will minimize the number of times an evacuation
is needed.
Provisions of a fire prevention plan include:
- Housekeeping
procedures for storage and clean-up of flammable materials
and flammable waste;
- Procedures
for controlling ignition sources such as smoking, welding,
and burning;
- Procedures
for maintenance and cleaning of heat-producing equipment,
such as burners, ovens, stoves, and fryers; and
- Training
of employees in the potential fire hazards and the control
procedures in the fire prevention plan.
Automatic
fire suppression systems such as automatic sprinkler systems improve
fire safety in the workplace.
Automatic systems:
- Detect
the fire,
- Sound
an alarm, and
- Put
water or other suppression agent where heat and fire are located.
Automatic systems must be properly maintained.
If
a system is taken out of service during work hours a fire watch
must be substituted.
Special
requirements exist for automatic systems that use chemicals that
present a serious health hazard.
The
use of automatic systems must be covered by the emergency action
plan and fire prevention plan.
Specific OSHA Requirements
OSHA Requirements for workplace fire safety are contained in 29
CFR 1910 Subparts E and L.
1910 Subpart
E, Exit routes, emergency action plans, and fire prevention
plans. Contains the following sections: [Overheads]
- Definitions;
- General requirements;
- Means of egress, general; and
- Employee emergency plans and fire prevention plan.
1910 Subpart
L, Fire protection. Contains the following sections: [Overheads]
- Scope,
application and definitions applicable to this subpart;
- Fire brigades;
- Portable
fire extinguishers;
- Standpipe
and hose systems;

- Fire
detection systems; and
- Employee
alarm systems.
NOTE:
Employers in states with state-run safety and health plans should
check with their
state
agency. Their state may enforce standards that, while "as effective
as federal standards," may not be identical to the federal requirements.
