F04 - F04 Fireguard License Portable Fire Extinguishers Questions and Answers 1

Question 1

A Fireguard conducting a monthly 'quick check' on a portable fire extinguisher must verify several conditions. Which of the following is NOT a required part of this monthly inspection?

Accepted Answer

Weighing the extinguisher to check the agent level.

Answer

The monthly 'quick check' is a visual inspection that can be done by a trained individual and does not require a Certificate of Fitness. It includes checking for accessibility, ensuring the pressure gauge is in the green, and verifying the pin and seal are intact. Weighing the extinguisher is part of a more detailed annual maintenance check performed by a licensed professional, not the simple monthly visual inspection.

Question 2

While on patrol at a temporary outdoor concert, a Fireguard discovers a small fire in a trash can, fueled by paper and cardboard. Which class of fire extinguisher is the most appropriate to use in this situation?

Accepted Answer

Class A

Answer

The fire involves ordinary combustible materials like paper and wood, which are classified as a Class A fire. A Class A fire extinguisher, typically containing water or certain dry chemicals, is designed for this type of fire. Class B is for flammable liquids, Class C is for electrical fires, and Class K is for cooking oils and fats.

Question 3

A Fireguard must use the P.A.S.S. method to operate a portable fire extinguisher. What does the 'A' in the P.A.S.S. acronym stand for?

Accepted Answer

Aim the nozzle at the base of the fire.

Answer

The P.A.S.S. method is an acronym for the proper operation of a fire extinguisher. The steps are: Pull the pin, Aim the nozzle at the base of the fire, Squeeze the handle, and Sweep from side to side. Aiming at the base is crucial because it targets the fuel source of the fire.

Question 4

According to FDNY regulations, how should portable fire extinguishers be mounted?

Accepted Answer

The top of the extinguisher must be no more than 5 feet from the floor, and the bottom no less than 4 inches from the floor.

Answer

FDNY regulations specify mounting heights to ensure extinguishers are accessible. The top of the extinguisher should not exceed 5 feet above the floor, and there must be a minimum clearance of 4 inches between the bottom of the extinguisher and the floor. They should never be placed directly on the floor.

Question 5

A fire breaks out involving energized electrical equipment in a sound booth at a public assembly. Which of the following extinguisher types would be dangerous to use on this fire?

Accepted Answer

Water-based

Answer

A fire involving energized electrical equipment is a Class C fire. Using a water-based extinguisher is extremely dangerous because water conducts electricity, which can lead to electrocution and potentially spread the fire. CO2, dry chemical, and clean agent extinguishers are non-conductive and are appropriate for Class C fires.
