Fire Safety
A
fire safety plan is an essential part of any workplace safety program. In fact,
the Occupational Safety and Health Administration (OSHA) mandates it for
industry under 29 Code of Federal Regulations (CFR), Part 1910, Subparts E, L
and Q. These standards require that a written plan be prepared and communicated
to all employees. OSHA standards can be
readily accessed at www.osha.gov.
Remember
that the OSHA standards are the MINIMUM requirements for protection. If you
relied on these in a written test you would receive a grade of D. Standards
published by the National Fire Protection Association (NFPA) are much more
detailed. Best business practice is to exceed minimum requirements as much as
possible in order to ensure maximum protection of life and property.
A
good fire safety plan has three main elements. The first is prevention. The old
saying ‘An ounce of prevention is worth a pound of cure’ is very true in this
case. A fire that doesn't happen means savings in both property and, most
importantly, possible human suffering.
Evaluating the workplace for fire hazards and taking steps to reduce or
eliminate those hazards benefits everyone in the long run. One immediate and
positive effect for a business with a good fire safety plan is control of
insurance premiums.
The
second element of the plan is evacuation. Fires can spread with incredible speed.
The ability for all occupants of any structure to quickly leave the danger
zone is the best means of ensuring their safety in case a fire does break out.
The third element is fire fighting. This is the final element because, although
individuals can fight very small fires, the limited capacity of portable fire
extinguishers means that emphasis must always be placed on alerting and
evacuating the workforce as the first priority in any fire emergency. It
requires a substantial investment in equipment and training time for a private
company to create an effective fire brigade and this is usually done only
within large organizations. Most employers have to rely on the local fire
department to tackle any serious fire.
Fire
Prevention
The
OSHA standard for fire prevention plans is found under part 1910.38 (b). The
NFPA standard number is 1. These two standards require a written fire
prevention plan. The plan must contain a list of the major workplace fire
hazards together with proper handling and storage procedures for them. It must
contain a list of potential ignition sources and control procedures for them.
Also, the plan must identify the fire protection equipment to control these
hazards. Include the job titles of employees who are responsible for maintaining
fire detection and protection equipment, as well as those who are responsible
for control of fuel source hazards. In practical terms, the employer begins by
conducting an initial evaluation of the workplace to determine the hazards.
This is usually done in the planning stage of any new construction and is based
on the building and fire codes of the state and locality. In the case of
industries that handle flammable substances there will frequently be additional
Federal standards that must be met. The expertise of architects and process
design engineers is utilized in this instance. If an existing structure is
being leased or purchased, such an evaluation may not always be within the
ability of many employers. It is a good idea to call upon the resources of the
organization’s insurance carrier and request risk management services prior to
starting business operations. If the business expands, or processes are
modified, it will be necessary to re-evaluate the possible hazards and update
the prevention plan as changes take place.
When
a company adopts a fire protection plan, it is necessary to explain the plan to
each employee upon initial assignment of job duties. The employee must receive
all information needed for their safety. The employer must keep the written
plan on the premises and available to employees for review. When any change in
the plan occurs, notify employees prior to the change or at least prior to the
beginning of the next shift after a change takes place. Schedule annual
refresher training in the plan as well as a number of five-minute safety talks
throughout the year. Design these talks for the specific needs of work areas.
Businesses with fewer than ten employees may communicate the plan orally to
their staff but it must be maintained in written form to comply with the
standard.
Proper
safe storage of flammable or combustible liquids is covered in part
1910.106. This standard outlines the
types of permitted containers and their capacities for all classes of these
liquids. Flammables storage cabinets are very useful for businesses that use
small to moderate amounts of solvents or flammable paints. Boldly label
containers of substances that are fire hazards. Choose the hazard label system
that is best suited to your operation. Employers can choose between three
warning label systems, the NFPA diamond, the National Paint and Coatings
Association’s Hazardous Materials Information System (HMIS), or the American
National Standards Institute’s (ANSI) system.
Carefully examine storage of combustible solids, like paper supplies.
Never store them in electrical service rooms.
Housekeeping
is an important part of the plan. The standard states that the employer must
control accumulation of flammable or combustible wastes so they do not contribute
to a fire emergency. This is not necessarily limited to waste from
manufacturing processes. It also includes office, shipping or mailroom paper
and pasteboard waste. Remove combustible
waste from the workplace or store the waste in containers such as safety cans.
Empty these containers on a daily basis. The housekeeping procedures must be
included in the written plan. Conduct periodic inspections of hazard areas.
These inspections should be based on a written form that lists each hazard,
provides a means of recording and fixing problems, and is required to be signed
by the inspector. Make a sign-off form that verifies completion of any repairs
or corrections that are needed and maintain a file of completed forms.
Sources
of ignition include electric wiring and equipment. Power cords are often a
source of problems if they become damaged. If a plug is found to be missing its
grounding prong or the cord is worn or cut, tag it immediately and remove it
from service. Do not wrap cut or worn areas with tape because the internal
insulation between the current and ground wires might be damaged and a short
could occur. Never overload electrical outlets by using multiplex plugs to
connect more than two appliances or tools.
Do not use extension cords in place of permanent wiring. Do not staple
extension or appliance cords to walls or to doorframes, route them through
openings in walls, or wrap them around metal furniture. Periodically inspect fixed electrical
equipment and controls for wear or lack of lubrication that could lead to
overheating. Clean accumulations of grease and dust on air filter elements or
fans in electric-powered machinery on a regular schedule. One more possible
ignition source is static electricity.
When flammable or combustible liquids are transferred from one container
to another, use bonding wires to connect both containers and a grounding lead.
Cutting,
welding, and grinding operations must be controlled as well. Fire protection
standards for these operations are found in part 1910.252 (a). The basic
precautions for welding and cutting are based on the premise that the object to
be cut or welded cannot be moved. In these cases remove all fire hazards from
the immediate area. If they cannot be moved, place fireproof guards to confine
the heat, sparks, and slag. Trained firewatchers must be in place for
operations in areas where other than a minor fire might develop. Develop a
system of hot work permits to control all facets of these operations. Contractors performing hot work in the facility
are subject to the same hot work rules as regular employees.
Designate
smoking and non-smoking areas for each workplace and provide metal containers
to hold cigarette butts in the smoking area. Clearly mark any fire hazard areas
with signage forbidding any kind of smoking or open flame, even if the entire
structure is already a no-smoking zone. Although it is not required, include a
system of rules as part of the plan. Records and enforcement of infractions,
such as smoking in forbidden areas or blocking exits, should be in written form
with a graduated, fair system of penalties assessed for repeated violations. As
part of the prevention plan, maintain records of infractions.
Create
a written maintenance plan for fire suppression systems, as well as for systems
installed on heat-producing equipment to prevent accidental ignition of
combustibles.
Evacuation
Employers
must prepare a written emergency action plan and procedures for reporting fires
must be written into the plan. Emergency escape procedures and routes must be a
part of the action plan. Post floor plans of these routes in all rooms and work
areas of the business. Show main and alternate routes on these plans whenever
possible and define them by different colors. Some requirements in the OSHA
standard 1910.37 include minimum width of the exit routes, access to exits,
occupant load egress capacity, design of exit doors and walking surfaces. Clear
marking of exits, as well as doors that are not exits, is mandated. The size of
exit signs and sources of illumination for them must conform to this
standard. Nothing must be allowed to
obscure the view of any signage or exit doors. The NFPA’s Life Safety Code
101-2000 contains extensive standards for exit routes from every type of public
structure. This publication serves as the basis for many municipal codes in
the United States
and can be purchased from NFPA. They may be contacted at www.nfpa.org/.
Compliance with the exit route provisions in 101-2000 makes you compliant with
OSHA’s exit route requirements. OSHA requires an alarm system to alert
employees to a fire emergency. Standards for these systems may be found in part
1910.165. Audible alarms must be distinctive and must be loud enough to be
perceived above the ambient noise level in the workplace. If any employees have
vision or hearing impairments, alarms must be designed to alert them. Otherwise
a variety of alarms is acceptable. Test alarm systems every two months.
Teach
each employee the action plan so that they know what actions they must take in
each type of emergency. The written plan must contain the job titles of persons
who can be contacted by the employee for further explanation of duties under
the plan. Teach all employees the correct sequence of actions in a fire
emergency. When a fire is discovered, the first thing to do is sound the alarm.
The second action is to call the fire department or company fire brigade if
there is time to do so. The employee should identify her/himself, the location
and type of fire. The third thing to do, and only after completing the first
two, is to try to fight a small fire. It must be emphasized that the employee
should do this only if they have been trained in the use of the extinguisher
and if the situation allows the following three conditions; the employee has
their back to the exit route, another person is present to help out, and the
room is not full of smoke.
In
case of an emergency some employees may be required to perform shutdown of
critical operations or systems prior to evacuating the premises. Include these
duties in the written plan with the job titles of these people. If any
employees are assigned rescue or medical duties, such duties must be in writing.
Appoint fire wardens and train them to aid in evacuations. The recommended ratio
of employees to wardens is 20 to 1. In multi- story buildings, assign a warden
to each floor at a minimum. For businesses that schedule work by shifts,
wardens have to be present on all shifts. Wardens and employees should be aware
of and ready to assist any fellow employees who may be mobility impaired and
might require assistance in an evacuation. The designated shutdown employees
and wardens must be trained prior to implementation of the action plan.
Set
up a safe area or refuge where all employees are to gather after the
evacuation. It is important that the area be sufficiently far from the
structure to be secure from possible further hazards that may occur after the
evacuation and to allow emergency response personnel and vehicles free access.
Develop a procedure to account for all persons who were in the structure prior
to the evacuation. This should include any visitors, customers, delivery, or
contractor personnel who might be on the premises. This accounting is normally
an assignment for supervisors and/or fire wardens.
Schedule
fire escape drills at the startup of business operations and at least twice a
year thereafter. Drills are important for checking the effectiveness of the
escape plan and improving it. Even more important, if duties and necessary
actions are effectively conveyed to people, they will revert to their training
in times of stress. This will combat panic. Panic is a major cause of injury
and death in fire emergencies. As a key part of the training, make each
employee simulate, in a safe manner, conditions of limited visibility on their
route of egress. Some examples of this
are to have employees memorize the number of footsteps and direction changes
needed to reach safety or (for those who are able) practice moving to the exits
in a position near the floor. For buildings where multiple businesses are
located, all of the tenant companies should coordinate their evacuation plans
and conduct joint drills.
Fire
Fighting
Federal,
state, and local codes may require portable fire extinguishers to be available
in an enclosed workplace. The OSHA standard for these is part 1910.157. Some
exemptions to the standard are also found here. The NFPA standard is number
10. Employers are required to provide,
mount, and identify fire extinguishers so that they are readily available to
employees. These extinguishers must be approved types and be selected on the
basis of the types of fires that are expected to occur in the workplace. It is
best to purchase multi-rated extinguishers for general protection. The most
widely produced type of extinguisher is the dry chemical type rated for class
A, B, and C fires.
- Class A fires are those
caused by burning of ordinary combustibles such as wood, paper, cloth or
plastics.
- Class B fires are those
involving flammable or combustible liquids.
- Class C fires are fires
in energized electrical equipment.
- Class D fires are those
of combustible metals such as magnesium.
The
initial evaluation of fire hazards will reveal the need for any specialized
extinguishers. The employer is required to maintain the extinguishers in a
state of readiness in their designated places at all times.
- Extinguishers for class
B fires must be located so that they are no more than 50 feet from the
hazard area.
- Those for class A and C
fires can be no more than 75 feet of travel distance from any employee.
Do
not mount extinguishers in any location that requires a portable device such as
a ladder to access them. All extinguishers must be visually inspected on a
monthly basis. They must undergo a maintenance inspection annually and records
of the inspection dates must be retained for one year. Rechargeable dry
chemical extinguishers must be emptied and examined internally every six years
and hydrostatically tested every twelve years. Carbon dioxide and nitrogen
extinguishers and pressure bottles must be hydrostatically tested every five
years. When extinguishers are removed for maintenance, they must be replaced
while maintenance is in progress. If the employer does hydrostatic testing, all
items under standard 1910.158 (f) apply. When an employer provides portable
extinguishers for use by employees, training must be given in the use of the
extinguishers and information provided on the hazards of fire fighting.
Training in these hazards is of the utmost importance. Once again, give this
training upon initial assignment of job duties and on an annual basis
thereafter.
If
a workplace only contains hazards for class A fires, the employer may choose to
install a standpipe and hose system instead of portable fire extinguishers.
That system will have to conform to standard 1910.158. The standpipes and hoses
must be protected from damage so that they will be available in an emergency.
Cabinets or hose covers must be used to protect the hoses from weather, dirt,
and possible damage. Access to the hoses must be unobstructed. Inspect all
hoses on an annual basis and discard them when they deteriorate. Hose is
considered deteriorated when it can no longer carry water at the required flow
rate and pressure.
Automatic
fire control systems include sprinkler systems, dry chemical systems, systems
that dispense gaseous agents and those that dispense foam or large amounts of
water. Each has a standard assigned to it from parts 1910.159 to 1910.163.
Sprinkler
systems that are required by OSHA in certain types of workplaces fall under
standard 1910.159. Under this standard the following items apply. The system must provide complete coverage
for the areas in which it is installed. The employer must maintain the system
properly and perform a main drain flow test every year. Every two years the
inspector’s valve must be opened to assure the system operates correctly. Upon
the completion of a new system, acceptance tests must be performed and documented.
Water supply for the system must provide the designed flow for a minimum of 30
minutes. The employer may provide auxiliary hose connections to input more
water for fire fighting use provided that the water source supplies the
designed demand for the system. Protection for the system shall be provided
against freezing and exterior corrosion. The sprinklers shall be protected
against mechanical damage. The system must have the ability to be totally
drained. A water flow alarm must be included on any system of more than 20
sprinkler heads. When materials are stored in sprinkler- protected areas, a
minimum clearance of 18 inches must be left between the sprinklers and the material
below them.
Fixed
extinguishing systems other than sprinkler systems that may, by means of their
operation, expose employees to injury, death, or adverse health consequences
from the extinguishing agent are covered under parts 1910.160 to 1910.163.
Install a distinctive alarm to alert employees prior to the system discharging so
that they may safely leave the area. Post hazard warnings at entrances to and
inside areas where concentrations of the extinguishing agent may be hazardous
to life and health. Provide safeguards to warn employees against entry into
areas where the atmosphere remains hazardous after a discharge. Inspect the
system annually. Check pressure and contents of refillable containers every six
months. Non-refillable containers must be weighed every six months. All
inspection and maintenance dates must be recorded on the containers. Maintenance and inspection personnel must be
trained and annually reviewed on their training. In addition to the automatic
release mechanism, one manual release must be included in the system. When
systems are recharged after use, it must be with an identical agent to that
previously used in the system. Systems using gaseous agents have a set of
required times for extinguishing concentrations of the gases. All gases other
than Halon must reach the extinguishing level within 30 seconds after start of
the discharge.
Fire
brigades are not required under OSHA standards. Employers must decide whether
organizing and properly equipping a fire brigade is needed and is within the
ability of the organization. If it is decided to create a fire brigade, part
1910.156 will regulate it. Create a
written policy that outlines the organizational structure and size of the
brigade, as well as the type and frequency of training it receives and its
duties in the workplace. Make sure that
the members of the brigade are physically capable of performing the duties
assigned to them. Conduct training at least annually. Content of the training
must be equivalent to that conducted by recognized fire training schools in the
various states. A large part of the standard
is concerned with approved protective clothing and equipment for brigade
members who are required to perform fire fighting inside structures.
