A fire extinguisher is a handheld device that contains a chemical or water to put out small fires. Fire extinguishers are used in emergencies to escape buildings.
A fire alarm is a system that detects and warns people of fire, smoke, or carbon monoxide. It's made up of several devices, including smoke detectors, heat detectors, and manual call points.
Emergency lighting is a backup lighting system that automatically activates when the main power supply fails. It's designed to illuminate escape routes and exits so people can safely evacuate a building in the event of a power outage or fire.
