Form 4 Science: Fire Extinguisher Flashcards

Vocabulary-style flashcards covering the types, usage, and safety protocols for fire extinguishers as outlined in Section 4 of the Science curriculum.

Fire Extinguisher

A device used to extinguish fires at an early stage before they grow larger.

Fire Triangle

The three essential elements required for a fire to start and continue: Heat, Fuel, and Oxygen.

Fire Extinction Method

The process of putting out a fire by removing at least one element of the fire triangle.

Water Extinguisher

An extinguisher that uses water to lower the temperature of burning materials; it features a red label.

Foam Extinguisher

An extinguisher that creates a foam layer to block oxygen from reaching the burning material; it features a cream label.

Carbon Dioxide ($CO_2$) Extinguisher

An extinguisher that uses $CO_2$ gas to prevent oxygen from supporting combustion; it features a black label.

Dry Powder Extinguisher

An extinguisher containing chemical powder that interferes with the combustion reaction; it features a blue label.

Electrical Fire Safety

Water must never be used for these fires due to electric shock risks; $CO_2$ or dry powder extinguishers should be used instead.

Oil Fire Extinguishing Agents

Suitable agents include foam, dry powder, or $CO_2$; water should never be used on oil fires.

Red Label

The color indicator used for water-type fire extinguishers.

Blue Label

The color indicator used for dry powder-type fire extinguishers.

Black Label

The color indicator used for carbon dioxide ($CO_2$) fire extinguishers.

Cream Label

The color indicator used for foam-type fire extinguishers.

PASS Technique

A procedure for using an extinguisher: Pull the pin, Aim the nozzle, Squeeze the handle, and Sweep from side to side.

Base of the Fire

The specific area where the extinguisher nozzle should be aimed to remove the source of combustion effectively.

Uncontrolled Fire Protocol

The immediate action of evacuating the area and contacting the fire department (bomba) if the fire cannot be contained.

Fire Suppression Principle

The act of breaking the combustion chain reaction by removing heat, fuel, or oxygen.
