Fire Safety and Prevention 181
The class Fire Safety and Prevention examines common workplace fire safety procedures. Fires, no matter how small, should be reported immediately. Buildings are equipped with extinguishing systems that actuate an alarm and discharge an extinguishing agent to control advanced stage fires. Portable fire extinguishers are available for extinguishing incipient stage fires using the P.A.S.S. technique. Employees not authorized to fight the fire should evacuate immediately. Employers should create an emergency action plan that dictates the procedures to be carried out in the event of an emergency. In the event of a fire, employees should stay calm, follow procedures, and go directly to assembly areas. Employers must account for all employees and provide first aid until medical services arrive. After taking this class, users will be able to describe OSHA regulations regarding fire safety and how they impact day-to-day operations in the workplace.

carbon dioxide extinguishers
A fire extinguisher filled with carbon dioxide under extreme pressure. Carbon dioxide extinguishers are used to extinguish electrical (Class C) fires.
A technique designed to temporarily circulate oxygenated blood through the body of a person whose heart has stopped. Cardiopulmonary resuscitation is commonly known as CPR.
chain of command
The sequence of individuals responsible for coordinating the work of an emergency response team. The chain of command usually includes at least a coordinator and a backup coordinator.
Class A fires
An ordinary combustible fire of wood, cloth, paper, rubber, or plastic. Class A fires can be extinguished with air-pressurized water extinguishers.
Class B fires
A flammable liquid fire of oil, grease, tar, or gas. Class B fires can be extinguished with dry chemical extinguishers.
Class C fires
An electrical fire caused by live electrical equipment such as wires and overloaded outlets. Class C fires can be extinguished with carbon dioxide extinguishers.
Class II systems
A 1.5 inch (3.81 centimeter) diameter hose system which provides a means for the control or extinguishment of incipient stage fires. Any employee can use a Class II system.
Class III systems
A standpipe system that can only be used by employees trained in fighting fires. Class III systems can put out fires somewhat larger than incipient stage.
clean-agent fire extinguishing system
An engineered set of components that work together to detect a fire, alert occupants, and extinguish a fire. Fixed fire extinguishing systems use a gas or chemical extinguishing agent to extinguish fires.
A machining process that uses a tool to create chips and remove metal from a workpiece. Cutting creates sparks, which can be a fire hazard near flammable materials.
dry chemical extinguishers
A fire extinguisher filled with a flame-retardant powder, which separates fuel from oxygen. Dry chemical extinguishers are used to extinguish flammable liquid (Class B) fires.
emergency action plan
A written plan detailing procedures to facilitate and organize employer and employee actions during an emergency. An emergency action plan should include evacuation, critical shutdown, and emergency reporting procedures, as well as methods for accounting for personnel and rescue and medical duty assignment.
emergency response coordinator
The designated employee responsible for carrying out established emergency response procedures. The internal chain of command is led by the emergency response coordinator.
An employee designated to help move other employees to safety. There is usually one evacuation warden for every twenty employees.
A material used with fixed, automatic, or portable fire extinguishing systems to suppress or put out fires. Common extinguishing agents include water, air, carbon dioxide, and halon.
An audible or visual device that alerts occupants to a fire emergency. Fire alarms usually signal occupants to evacuate the building.
An internal or industrial fire department consisting of employees trained to fight incipient stage and advanced stage fires. Fire brigades should be re-trained yearly.
A device that senses smoke, heat, or flames from a fire. When a fire detector senses a fire, it actuates an audible and/or visual alarm.
fire extinguishing system
A fixed or automatic system used for controlling or putting out fires. Fire extinguishing systems also detect fires and alert occupants.
fire prevention plans
FPP. A plan of proactive procedures implemented to avoid fires in the workplace. FPPs include such things as a list of all major fire hazards and types of fire protection equipment needed to control these hazards.
fixed fire extinguishing systems
Any fire extinguishing system permanently installed in a building. The requirements for a fixed fire extinguishing system should be located in a fire prevention plan.
