Precendents

According to the Bureau of Labor Statistics' Census of Fatal Occupational Injuries Charts, 1992-2007 [372 KB PDF, 17 pages], fires and explosions accounted for 3% of workplace fatalities in 2007. This page provides valuable reference materials for prevention of fire-related injuries in all workplaces. Fire safety is addressed in specific standards for recordkeeping, general industry, shipyard employment, marine terminals, longshoring, gear certification, and the construction industry. This page highlights OSHA standards, the Regulatory Agenda (a list of actions being taken with regard to OSHA standards), directives (instructions for compliance officers), and national consensus standards related to fire safety. Fire safety becomes everyone's job at a worksite. Employers should train workers about fire hazards in the workplace and about what to do in a fire emergency. This plan should outline the assignments of key personnel in the event of a fire and provide an evacuation plan for workers on the site. In the construction industry, a "fire plan" should be set up prior to the beginning of any demolition job.

What should employers do to protect workers from fire hazards

Employers should train workers about fire hazards in the workplace and about what to do in a fire emergency. If you want your workers to evacuate, you should train them about how to escape. Just as, if you expect your workers to use firefighting equipment, you should give them appropriate equipment and train them to use the equipment safely.

Equipment

Examples of equipment that needs to be maintained include: Hose reels and cabinets Hose outlets and connections, mounting Hose, connected or readily available Nozzles, shut-off type (straight or fog) Water supply, 100 gpm for 30 minutes

Fixed Fire Suppression Equipment

Fixed Extinguishing Systems Section 1910.160 This section applies to all fixed extinguishing systems installed to meet a particular OSHA standard except for automatic sprinkler systems, which are covered under 1910.159. General Requirements Fixed extinguishing system components and agents shall be designed and approved for use on the specific fire hazards they are expected to control or extinguish: Designed and approved for specific hazards Noticeable distinctive alarms required Safeguards to prevent employee entrance Hazard warning or caution signs Systems inspected annually

What are the rules for fixed extinguishing systems

Fixed extinguishing systems throughout the workplace are among the most reliable fire fighting tools. These systems detect fires, sound an alarm, and send water to the fire and heat. To meet OSHA standards, employers who have these systems must: Substitute (temporarily) a fire watch of trained employees to respond to fire emergencies when a fire suppression system is out of service. Ensure that the watch is included in the fire prevention plan and the emergency action plan. Post signs for systems that use agents (e.g., carbon dioxide, Halon 1211, etc.) posing a serious health hazard.

Do employers have to provide portable fire extinguishers

No. But if you do, you must establish an educational program to familiarize your workers with the general principles of fire extinguisher use. If you expect your workers to use portable fire extinguishers, you must provide hands-on training in using this equipment.

Must employers develop emergency action plans

Not every employer is required to have an emergency action plan. OSHA standards that require such plans include the following: Process Safety Management of Highly Hazardous Chemicals, 1910.119 Fixed Extinguishing Systems, General, 1910.160 Fire Detection Systems, 1910.164 Grain Handling, 1910.272 Ethylene Oxide, 1910.1047 Methylenedianiline, 1910.1050 1,3 Butadiene, 1910.1051 When required, employers must develop emergency action plans that: Describe the routes for workers to use and procedures to follow. Account for all evacuated employees. Remain available for employee review. Include procedures for evacuating disabled employees. Address evacuation of employees who stay behind to shut down critical plant equipment. Include preferred means of alerting employees to a fire emergency. Provide for an employee alarm system throughout the workplace. Require an alarm system that includes voice communication or sound signals such as bells, whistles, or horns. Make the evacuation signal known to employees. Ensure emergency training. Require employer review of the plan with new employees and with all employees whenever the plan is changed.

Must employers have a fire prevention plan?

OSHA standards that require fire prevention plans include the following: Ethylene Oxide, 1910.1047 Methylenedianiline, 1910.1050 1,3 Butadiene, 1910.1051 Employers covered by these standards must implement plans to minimize the frequency of evacuations. All fire prevention plans must: Be available for employee review. Include housekeeping procedures for storage and cleanup of flammable materials and flammable waste. Address handling and packaging of flammable waste. (E.g., Recycling of flammable waste such as paper is encouraged.) Cover procedures for controlling workplace ignition sources such as smoking, welding, and burning. Provide for proper cleaning and maintenance of heat producing equipment such as burners, heat exchangers, boilers, ovens, stoves, and fryers, and require storage of flammables away from this equipment. Inform workers of the potential fire hazards of their jobs and plan procedures. Require plan review with all new employees and with all employees whenever the plan is changed.

Sprinkler Alarms

On all sprinkler systems having more than twenty (20) sprinklers, the employer shall assure that a local water flow alarm is provided which sounds an audible signal on the premises upon water flow through the system equal to the flow from a single sprinkler.

How to use a fire extinguisher

PASS System of Using Portable Fire Extinguishers It's easy to remember how to use a fire extinguisher if you can remember the acronym PASS, which stands for Pull, Aim, Squeeze, and Sweep. P - Pull the pin. A - Aim nozzle at base of flames. S - Squeeze the trigger. S - Sweep the extinguisher from side to side, covering the area of the fire with the extinguishing agent.

The employer shall record the annual maintenance date and retain this record for one year after the last entry, or for the life of the shell, whichever is less.

Introduction

There is a long and tragic history of workplace fires in this country. One of the most notable was the fire at the Triangle Shirtwaist Factory in New York City in 1911, in which nearly 150 women and young girls died because of locked fire exits and inadequate fire extinguishing systems. History repeated itself several years ago in the fire in Hamlet, North Carolina, where 25 workers died in a fire in a poultry processing plant. It appears that here, too, there were problems with fire exits and extinguishing systems.

Fixed Systems Gaseous Agent Section 1910.162

This scene discusses all fixed extinguishing systems, using a gas as the extinguishing agent, installed to meet a particular OSHA standard. These systems shall also comply with 1910.160. In some cases, the gas may be in a liquid state during storage.

Fire Detection Systems

This scene focuses on all automatic fire detection systems installed to meet the requirements of a particular OSHA standard. Restore to normal condition ASAP after testing or activation The employer shall assure that all devices and equipment constructed and installed to comply with this Standard are approved for the purpose for which they are intended. Maintenance and Testing: Maintained in operable condition Test system as needed to ensure reliability Only trained personnel on system

Training and Education

Where the employer has provided portable fire extinguishers for employee use in the workplace, the employer should also provide an educational program to familiarize employees with the general principles of fire extinguisher use and the hazards involved with beginning stage fire fighting. The employer shall provide the following: Initial and annual training The required training upon initial assignment to the designated group of employees and at least annually, thereafter

Number, Location, and Spacing of Detectors

Based on design data from multiple sources: The employer shall assure that the number, spacing, and location of fire detectors is based upon design data obtained from field experience, or tests, engineering surveys, the manufacturer's recommendations, or a recognized testing laboratory listing.

What does OSHA require for emergency fire exits

Every workplace must have enough exits suitably located to enable everyone to get out of the facility quickly. Considerations include the type of structure, the number of persons exposed, the fire protection available, the type of industry involved, and the height and type of construction of the building or structure. In addition, fire doors must not be blocked or locked when employees are inside. Delayed opening of fire doors, however, is permitted when an approved alarm system is integrated into the fire door design. Exit routes from buildings must be free of obstructions and properly marked with exit signs.

Selection and Distribution

Portable fire extinguishers shall be provided for employee use. They should be selected and distributed based on the classes of anticipated workplace fires and on the size and degree of hazard that would affect their use.

Testing unsupervised alarms every two months

The employer shall assure that a test of the reliability and adequacy of non-supervised employee alarm systems is made every two months.

Maintenance and Testing - Maintain in operating condition

The employer shall assure that all employee alarm systems are maintained in operating condition except when undergoing repairs or maintenance.
