OSHA requires that all employers provide adequate emergency lighting in their workplaces. This means that the workplace must be well illuminated with sufficient light levels to provide safe passage and evacuation of workers during emergencies. The required level of illumination should allow personnel to identify hazards, read signs and labels, access exit routes, use handrails or stairs on stairways, distinguish between flooring materials such as carpeted areas and slippery surfaces, activate fire protection systems when necessary, evacuate safely from the building and perform other tasks needed for a successful emergency response. Additionally, OSHA requires employers to ensure that the emergency lighting is properly maintained by testing it regularly according to its manufacturer’s instructions.
