Emergency lights are safety lights that automatically turn on when there is no power. These lights illuminate the emergency exit paths and ensure the safe exit of occupants in case of a blackout or fire emergency. Here, we are going to discuss two different types of hazard lights, why we need them and how long should we keep them on. So, let’s get started.
Types of emergency lighting
It is of two types i.e., maintained and non-maintained emergency lighting. Let’s discuss both of these types in detail below.
Maintained lights
These emergency lights stay on all the time and are an integral part of the normal lighting system. In the event of power failure, these lights take power from the battery backup and illuminate the emergency routes for safe evacuation.
Non-maintained lights
These lights stay off when the power supply is available and get activated when there is a power cut. This is temporary lighting that lits up to guide people to evacuate the building during emergencies.
