All PPE designed for structural fire fighting must meet the requirements of this NFPA standard.

NFPA 1971

100

This is the primary type of respiratory protection used in the fire service.

Atmosphere-Supplying Respirator (ASR)

100

These fires involve ordinary combustibles such as wood, paper, and many plastics.

Class A fires

100

This method of extinguishment excludes oxygen from the burning process.

Smothering

100

When using a fire extinguisher, you should always approach the fire this direction relative to the wind.

Upwind

200

This alarm is designed to activate when a firefighter remains motionless for more than 30 seconds.

Personal Alert Safety System (PASS)

200

This SCBA component displays lights that indicate the amount of air left in the SCBA cylinder.

Heads Up Display (HUD)

200

These fires involve energized electrical equipments.

Class C

200

This process, used by Class K extinguishers, converts fatty acids into soapy film to extinguish a fire.

Saponification

200

This is the first step in the PASS application method for operating a protable fire extinguisher.

Pull the pin

300

PPE must be properly cleaned because chemicals, oils and petroleum products on the outer shell can do this when exposed to fire.

Ignite

300

This feature allows an SCBA air cylinder to be transfilled from another cylinder in the event of an emergency.

Universal Air Coupling (UAC)
300

This class of fire involves combustible metals and alloys such as magnesium, lithium, and titanium.

Class D

300

This type of extinguishing agent should be used in areas with hightly sensitive computer equipment because it causes less damage than other agents.

Clean agent

300

When applying a dry powder agent to a combustible metal fire, it is critical to avoid doing this to the crust that forms over the material.

Breaking the crust

400

This component of the protective coat is designed to make firefighters more visible at night or in low light conditions.

Retroreflective trim

400

These are defined as situations or events that signal the need for a firefither to exit a hazardous area.

Exit indicators

400

These fires involve cooking oils and fats in commercial kitchens.

Class K

400

This agent is effective on burning puddles of gasoline because it forms a film that bloats on the fuel's surface.

Aqueous Film Forming Foam (AFFF)

400

This type of training helps firefighters overcome psychological limitations such as fear and claustrophobia while wearing SCBA.

Repetition

500

This specific item of wildland firefighting PPE is a piece of flame-resistant fabric that attaches to the helmet to protect the face and neck.

Face/neck Shroud

500

If the pressure reading on the remote pressure gauge does not match the reading on the regulator, you should assume this reading is the correct one.

Lowest number

500

This class of fire involves flammable and combustible liquids and gases like gasoline and alcohol.

Class B

500

This extinguishing method works by interrupting the chemical chain reaction in the burning process.

Chemical flame inhibition

500

According to general guidelines, you should only enter and IDLH atmosphere if you are working in a team of at least this many people.
