Operational Response
This is the first priority of every firefighter upon arriving at an emergency incident.
What is life safety?
This is the recommended compression-to-ventilation ratio for one-rescuer adult CPR.
Question: What is 30 compressions to 2 breaths?
These four elements make up the Fire Tetrahedron.
What are heat, fuel, oxygen, and the chemical chain reaction?
This device measures the pressure produced by a fire pump.
What is a pressure gauge?
This extinguishing agent is commonly used on flammable liquid fires in fuel storage facilities.
What is foam?
This incident management principle ensures firefighters know exactly who they report to.
What is chain of command?
This type of bleeding is bright red and spurts with each heartbeat.
What is arterial bleeding?
This method of heat transfer occurs through direct contact.
Question: What is conduction?
This formula is used to calculate the flow of water from a nozzle.
What is Q = A × V (Flow = Area × Velocity)?
This type of fire involves flammable liquids such as gasoline and diesel.
What is a Class B fire?
This report is transmitted immediately upon arrival and includes conditions, actions, and resource requirements.
What is a size-up (or initial size-up report)?
This condition occurs when the body's temperature rises above normal with little or no signs of sweating due to prolonged heat exposure.
What is heat stroke?
This stage of fire development is characterized by rapid fire growth and increasing heat.
What is the growth stage?
What is the reduction in fluid pressure or energy caused by the resistance between moving liquid and the inside walls of pipes, hoses, or fittings called.
Question: What is friction loss?
This firefighting tactic cools adjacent equipment to prevent fire spread.
What is exposure protection?
This operational procedure is used to confirm that all personnel have exited a hazardous area.
Question: What is a personnel accountability report (PAR)?
This recovery position helps maintain an open airway in an unconscious breathing casualty.
What is the recovery position?
This dangerous event occurs when nearly all combustible materials ignite simultaneously.
What is flashover?
This pressure is needed at the nozzle to produce an effective fire stream.
What is nozzle pressure?
This system mixes foam concentrate with water before discharge through nozzles.
What is a foam proportioning system?
These three priorities guide tactical decision-making at every emergency.
What are life safety, incident stabilization, and property conservation?
This medical condition results from inadequate tissue perfusion due to inadequate blood flow to vital organs.
What is hypovolemic shock?
This explosive event occurs when oxygen is introduced into a confined, oxygen-deficient fire.
What is a backdraft?
This pump operation ensures the pump and suction hose are filled with water before pumping.
What is priming the pump?
This phenomenon occurs when liquefied petroleum gas containers fail catastrophically due to heat.
What is a BLEVE (Boiling Liquid Expanding Vapour Explosion)?
