Emergency lighting is a lifeline in hazardous situations. It enables the safe, prompt and efficient evacuation of spaces and buildings, not only in cases of blackout caused by power outage, but when sunlight and lighting may still be available.

An effective emergency lighting system also guides people in and around enclosed and open environments, as well as helps them locate safety equipment plus refuge and assembly points.

In most countries, new guidelines ask for a "physical distance" to be maintained between people in particular scenarios. Building owners and safety managers must provide clear visible signage to educate and reinforce.
