Fire extinguisher

Fire extinguisher is a portable device that discharges a jet of water, foam, gas, or other material to extinguish a fire. Fire extinguishers are typically filled with water, foam, carbon dioxide, dry chemical, or wet chemical. They are used in emergency situations to control or extinguish small fires, often in emergency situations.

Types of Fire Extinguishers

There are several types of fire extinguishers, each designed to extinguish specific types of fires.

• Water and Foam: Water extinguishers or foam extinguishers extinguish the fire by taking away the heat element of the fire triangle. Foam agents also separate the oxygen element from the other elements.

• Carbon Dioxide: Carbon Dioxide extinguishers extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge.

• Dry Chemical: Dry Chemical extinguishers extinguish the fire primarily by interrupting the chemical reaction of the fire triangle.

• Wet Chemical: Wet Chemical extinguishers are a new agent that extinguishes the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the oxygen and fuel elements.

Usage

Fire extinguishers are used by pulling the pin and then aiming the nozzle at the base of the fire. The handle is then squeezed to release the extinguishing agent.

Maintenance

Fire extinguishers should be regularly checked to ensure they are fully charged and ready for use. This includes checking the pressure gauge, checking for physical damage and ensuring the pull pin is securely fastened.
