Fire Extinguisher Types

Fire extinguishers are essential safety devices used to control and extinguish fires. There are various types of fire extinguishers, each designed to combat specific classes of fire. Understanding the different types and their appropriate applications is crucial for effective fire safety.

Class A Fire Extinguishers

• Suitable for extinguishing fires involving ordinary combustible materials, such as wood, paper, and cloth.
• Typically contain water, foam, or dry chemical agents.
• Common examples: Water extinguishers, foam extinguishers, and dry chemical extinguishers.

Class B Fire Extinguishers

• Designed to extinguish fires involving flammable liquids, such as gasoline, oil, and grease.
• Contain agents that create a smothering layer or interrupt the combustion process.
• Common examples: Carbon dioxide extinguishers, dry chemical extinguishers, and foam extinguishers.

Class C Fire Extinguishers

• Suitable for extinguishing fires involving electrical equipment, such as computers, appliances, and wiring.
• Contain non-conductive agents to avoid electrical hazards.
• Common examples: Carbon dioxide extinguishers, dry chemical extinguishers, and dry powder extinguishers.

Class D Fire Extinguishers

• Specifically designed to extinguish fires involving combustible metals, such as magnesium, titanium, and sodium.
• Contain specialized agents that react with the burning metal to create a protective layer or extinguish the fire.
• Common examples: Met-L-X extinguishers and dry powder extinguishers.

Class K Fire Extinguishers

• предназначен для тушения пожаров, связанных с растительным маслом и жирами, таких как в коммерческих фритюрницах.
• Содержат специальные агенты, которые создают пленку на поверхности масла, препятствуя возгоранию.
• Обычные примеры: влажные химические огнетушители.

Fire Extinguisher Operation

Operating a fire extinguisher effectively requires a clear understanding of its principles and a step-by-step approach.

General Principles

• PASS Method:Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep from side to side.
• Extinguishing Agents:Fire extinguishers contain agents that either cool, smother, or inhibit the chemical reaction of the fire.
• Pressure:Extinguishers are pressurized to expel the extinguishing agent with sufficient force.

Step-by-Step Process

1. Pull the Pin:Remove the safety pin located at the top of the extinguisher.
2. Aim at the Base:Direct the nozzle at the base of the fire, where the fuel is most concentrated.
3. Squeeze the Handle:Press the handle to release the extinguishing agent.
4. Sweep from Side to Side:Move the nozzle back and forth across the base of the fire, covering the entire area.
5. Evacuate:Once the fire is extinguished, evacuate the area immediately.

Maintenance and Inspection, Fire extinguisher technician practice test

Proper maintenance and inspection of fire extinguishers are essential to ensure their reliability and effectiveness. Regular inspections should be conducted to check for:

• Physical damage
• Correct pressure
• Expiration dates

Fire Extinguisher Safety

Handling and using fire extinguishers safely is paramount to prevent accidents and injuries. It is crucial to follow established safety guidelines and be aware of potential hazards.

Safety Guidelines
