A firewall is a fire-resistant barrier used to prevent the spread of fire. Firewalls are built between or through buildings, structures, or electrical substation transformers, or within an aircraft or vehicle.
In firefighting, the policy of two-in, two-out refers to United States Occupational Safety and Health Administration (OSHA) policy 29 CFR 1910.134(g)(4)(i). The respiratory protection standard requires that workers engaged in fighting interior structural fires work in a buddy system; at least two workers must enter the building together, so that they can monitor each other's whereabouts as well as the work environment. There must also be at least two standby personnel outside the fire area prepared to rescue the inside firefighters should the need arise. One of these outside firefighters must actively monitor the status of the inside fighters but the second outside firefighter may perform a variety of other duties, such as pump operations, incident commander or outside hose line operation. There are no provisions in the standard to waive the requirements for either the "two-inside firefighters" or the "two-outside firefighters", although the circumstances under which this provision applies are more limited than generally understood.
"NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, and revised several times since then, it defines the "Safety Square" or "Fire Diamond" which is used to quickly and easily identify the risks posed by hazardous materials. This helps determine what, if any, special equipment should be used, procedures followed, or precautions taken during the initial stages of an emergency response. It is an internationally accepted safety standard, and is crucial while transporting chemicals.
A water tender, sometimes known as a water tanker, is a type of firefighting apparatus that specializes in the transport of water from a water source to a fire scene. Water tenders are capable of drafting water from a stream, lake or hydrant.
The publication Life Safety Code, known as NFPA 101, is a consensus standard widely adopted in the United States. It is administered, trademarked, copyrighted, and published by the National Fire Protection Association and, like many NFPA documents, is systematically revised on a three-year cycle.
A firefighter assist and search team (FAST), also known as a rapid intervention team/rapid intervention crew/rapid intervention group/rapid intervention dispatch (RIT/RIC/RIG/RID), is a team of two or more firefighters dedicated solely to the search and rescue of other firefighters in distress. Firefighter Assist and Search Team personnel shall have no other operational assignment during any incident. Multiple alarm fires may require multiple FAST/RIC teams.
In electrical and safety engineering, hazardous locations are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to electrical arcing, or high temperatures. Standards and regulations exist to identify such locations, classify the hazards, and design equipment for safe use in such locations.
NFPA 70E, titled Standard for Electrical Safety in the Workplace, is a standard of the National Fire Protection Association (NFPA). The document covers electrical safety requirements for employees. The NFPA is best known for publishing the National Electrical Code.
A rescue vehicle is a specialised vehicle designed to transport and provide the equipment necessary for technical rescue. Vehicles carry an array of special equipment such as the jaws of life, wooden cribbing, generators, winches, hi-lift jacks, cranes, cutting torches, circular saws and other forms of heavy equipment unavailable on standard trucks. This capability differentiates them from traditional pumper trucks or ladder trucks designed primarily to carry firefighters and their entry gear as well as on-board water tanks, hoses and equipment for fire extinguishing and light rescue. Most rescue vehicles lack on-board water tanks and pumping gear, owing to their specialized role. A rescue vehicle is typically operated by a rescue squad, but in some areas it may be integrated with emergency medical services or fire departments.
A fire pump usually refers to a pressure-increasing component of the water supply for fixed-place fire suppression systems such as fire sprinklers, standpipes, and foam systems. Fire pumps are also a critical component integrated into fire trucks and fire boats, and serve a similar purpose boosting water supplies for firefighting hose operations.
Fire investigation, sometimes referred to as origin and cause investigation, is the analysis of fire-related incidents. After firefighters extinguish a fire, an investigation is launched to determine the origin and cause of the fire or explosion. Investigations of such incidents require a systematic approach and knowledge of basic fire science.
A wildland fire engine or brush truck is a fire engine specifically designed to assist in fighting wildfires by transporting firefighters to the scene and providing them with access to the fire, along with water or other equipment. There are multiple types of wildfire apparatus which are used in different scenarios. According to the U.S. National Fire Protection Association, if the apparatus will be used primarily for outdoor and wildland responses, then it is to be considered a wildland fire apparatus and must conform to NFPA 1906.
A wildland water tender is a specialized vehicle capable of bringing water, foam, or dry chemicals to fire trucks in the field that are engaged on the fireline. Water tenders have a large truck mounted tank that carries a minimum 1,000 gallons and up to 4,000 gallons of water. These vehicles are specifically designed for fire fighting often with four-wheel drive, rugged suspension and high wheel clearance for mountainous dirt road conditions. According to the National Fire Protection Association, if the apparatus will be used primarily for outdoor and wildland responses, then it is to be considered a wildland fire apparatus and must conform to NFPA 1906.
Bunker gear is the personal protective equipment (PPE) used by firefighters. The term is derived from the fact that the trousers and boots are traditionally kept by the firefighters bunk at the fire station to be readily available for use.
Breaking capacity or interrupting rating is the current that a fuse, circuit breaker, or other electrical apparatus is able to interrupt without being destroyed or causing an electric arc with unacceptable duration. The prospective short-circuit current that can occur under short circuit conditions should not exceed the rated breaking capacity of the apparatus, otherwise breaking of the current cannot be guaranteed. The current breaking capacity corresponds to a certain voltage, so an electrical apparatus may have more than one breaking capacity current, according to the actual operating voltage. Breaking current may be stated in terms of the total current or just in terms of the alternating-current (symmetrical) component. Since the time of opening of a fuse or switch is not coordinated with the reversal of the alternating current, in some circuits the total current may be offset and can be larger than the alternating current component by itself. A device may have different interrupting ratings for alternating and direct current.
Essentials of Fire Fighting is a fire service training manual produced by Fire Protection Publications (FPP) and the International Fire Service Training Association (IFSTA). Fire Protection Publications is a department of Oklahoma State University College of Engineering, Architecture, and Technology (CEAT) in Stillwater, Oklahoma. This manual is used by fire service training agencies and departments around the world to train personnel to become firefighters. The Essentials of Fire Fighting is the required training manual used in countless local fire departments and state/provincial training agencies in every region of the United States and Canada. Since the release of the first edition of this manual in 1978, more than 2.5 million copies of the Essentials of Fire Fighting have been distributed to the fire service.
Flexible suction hose, not to be confused with hard suction hose in U.S., is a specific type of fire hose used in drafting operations, when a fire engine uses a vacuum to draw water from a portable water tank, pool, or other static water source. It is built to withstand vacuum, rather than pressure, abrasion, and heat. Conversely, hard suction is capable of withstanding up to 200 PSIG, as well as vacuum. In the United States, it is standard equipment according to the National Fire Protection Association standards for fire engines. It is used in both structural and wildland firefighting throughout the world, and is made in various diameters and connection types.
Firefighting in the United States dates back to the earliest European colonies in the Americas. Early firefighters were simply community members who would respond to neighborhood fires with buckets. The first dedicated volunteer fire brigade was established in 1736 in Philadelphia. These volunteer companies were often paid by insurance companies in return for protecting their clients.
A hazardous material (hazmat) apparatus is a vehicle used by emergency services to respond to calls involving potentially hazardous materials. These vehicles are customized to fit the needs of the agency responsible for the apparatus, which may be a rescue squad, fire department, emergency medical services, law enforcement agency, or military.
An air and light unit, also known as a breathing support unit, is a specialized piece of firefighting apparatus used by firefighters to provide supplemental lighting and SCBA air bottles at the scene of an emergency. During prolonged emergencies, particularly structure fires, where firefighters must remain on air, these air bottles will need to be replaced and refilled. The air and light unit has the ability to refill the SCBA bottles while in the field using onboard air compressors (cascade). It also carries a supply of spare air cylinders. These units are highly customizable and can vary greatly between departments. These multifunctional units are also equipped with diesel generators which supply electricity to power portable lights and overall scene illumination equipment. This is usually done via a roof-mounted telescoping light bank. The unit also has the ability to supply electrical power in an emergency to a shelter, base camp, or medical facility.
