退出 and 紧急 Lights

紧急 exit signs indicate the closest safe exit in case of an emergency. They’re required to be immediately recognizable and understandable to everyone and to be permanently lit so they are visible at all times. On the other hand, emergency lighting is a lighting apparatus that turns on automatically during a blackout and helps people safely evacuate the building.

No, the emergency lights will only turn on in case of a power outage. Once the power is restored, the lights will turn off, but the word “EXIT” permanently stays on.

一般, yes. However, it is important to check with your local regulations.

Each exit sign is equipped with an integral battery that provides power for emergency illumination if there is a power outage. 一般, exit signs must be connected to the circuit serving the normal lighting in the area as is required for unit equipment. Please refer to local regulations.

Any color that is readily visible or distinctive on exit signs is acceptable to OSHA, but it is important to review your local ordinances to understand local codes.
