History & Safety
This NFPA standard is the primary guide for Fire Department Occupational Safety, Health, and Training Programs.
What is NFPA 1500?
This type of construction, often called "Fire-Resistive," uses noncombustible materials like reinforced concrete and protected steel.
What is Type I Construction?
This stage of fire development occurs when all combustible materials in a compartment ignite almost simultaneously.
What is Flashover?
This component of the PPE ensemble is designed to protect the head from impact and heat, often featuring a shell and suspension system.
What is the Helmet?
A fire involving energized electrical equipment is classified as this letter class.
What is Class C?
This organizational principle states that each employee should report to only one supervisor.
What is Unity of Command?
These are the three components of the "Fire Triangle."
What are Fuel, Oxygen, and Heat?
This is the transfer of heat through a solid body or between two solids in direct contact.
What is Conduction?
This device emits a loud alarm if a firefighter remains motionless for a set period of time.
What is a PASS (Personal Alert Safety System)?
This rating on a fire extinguisher indicates it is suitable for use on combustible metals like magnesium.
What is Class D?
This nonprofit organization was created by Congress to lead a nationwide effort to remember fallen firefighters and assist their families.
What is the National Fallen Firefighters Foundation (NFFF)?
This type of building construction uses large-dimension lumber (greater than 8 inches) and is commonly known as "Heavy Timber."
What is Type IV Construction?
This explosive event occurs when oxygen is introduced into a ventilation-controlled, smoldering fire.
What is a Backdraft?
This is the minimum oxygen concentration level below which an atmosphere is considered "Oxygen Deficient" and requires SCBA.
What is 19.5%?
This common prying tool features a claw on one end and a spike/pick and an adze on the other.
What is a Halligan Bar?
In this specific type of fire department, the municipality or county provides funding, and personnel are full-time paid employees.
What is a Career Department?
This term describes the tendency of a gas or liquid to rise or sink based on its density compared to air.
What is Vapor Density?
This chemical process involves the decomposition of a solid material by heat, often preceding combustion.
What is Pyrolysis?
This specific SCBA component allows two firefighters to share air from one cylinder in an emergency.
What is the EBSS (Emergency Buddy Support System)?
These are the four methods by which fire extinguishers put out fire: Smothering, Cooling, Chemical Flame Inhibition, and this.
What is Saponification? (Acceptable: Oxygen Depletion)
This is the most common power source used by emergency services to operate lights, fans, and small tools at a scene.
What is a Portable Generator?
This common synthetic building material, often used in siding, can release highly toxic hydrogen cyanide gas when burned.
What is PVC (Polyvinyl Chloride)?
A fire is considered to be in this state when its growth is limited by the amount of oxygen available.
What is Ventilation-Limited?
This layer of the turnout coat is designed to prevent the transfer of water and corrosive liquids to the skin.
What is the Moisture Barrier?
This type of portable fire extinguisher uses a pressurized stream of water treated with a wetting agent to penetrate deep into upholstery or baled cotton.
What is a Stored-Pressure Water Extinguisher?
