An important aspect of emergency lighting design is its visibility in smoke. In emergencies, such as fires, smoke can rapidly obscure visibility, making it difficult to navigate through affected areas. Emergency lighting needs to stand out clearly, even in conditions filled with smoke or darkness, ensuring that individuals can find their way to safety or locate exits quickly. This is crucial for maintaining safety and helping to prevent injuries in critical situations.

Other considerations in emergency lighting design include adequate illumination levels and the appropriate placement of lights to eliminate dark areas, but visibility through smoke specifically addresses the life-safety aspect of emergency response. This ensures that in an unexpected emergency, the lighting system effectively guides personnel safely through hazardous environments.
