Emergency Light Testing is a legal requirement under the Regulatory Reform (Fire Safety) Order 2005, ensuring emergency exit routes remain illuminated during power failures. These lights guide occupants to safety in emergencies, making regular testing vital for compliance. Monthly functional tests check if lights activate when power is cut, while annual full-duration tests verify they last the required three hours. Businesses, schools, and public buildings must maintain logs of all tests to prove compliance with fire safety regulations. Faulty emergency lighting can lead to severe penalties or endanger lives during evacuations. Professional servicing ensures systems function correctly when needed most.
