A fire extinguisher is a safety device used to put out small fires. It contains chemicals that stop fire by cutting off oxygen or cooling the burning material.

The main types include water, foam, carbon dioxide (CO2), dry powder, and wet chemical extinguishers. Each type is designed for different classes of fire such as electrical, oil, or ordinary combustible fires.

A fire alarm system is a safety system that detects smoke or heat and gives an early warning sound. It helps people evacuate the building quickly and safely.

A fire hose reel is a long hose connected to a water supply inside buildings. It is used to control or extinguish fires, especially before the fire brigade arrives.
