Lights used for fire alarm signaling only or indicating complete evacuation shall be what color?

Lights used for fire alarm signaling or indicating complete evacuation should be clear or nominal white for a couple of important reasons. Clear or white lights offer maximum visibility, which is crucial in emergencies where every second counts. In situations like fires, the prompt awareness of an alarm signal can be life-saving, making it essential for lights to stand out and be easily recognized.

The use of a clear or nominal white color is aligned with standard practices, as it serves to maintain consistency across various facilities and systems. By using a uniform color that is easily distinguishable, it helps ensure that all occupants, regardless of their familiarity with the specific space, can quickly understand the signals being communicated.

This color standardization is important for safety regulations and codes, which often dictate specific requirements for emergency systems to minimize confusion and enhance the efficiency of response during emergencies. Consequently, clear or nominal white lights have been established as the correct choice in the context of fire alarm signaling and evacuation indications.
