Emergency Lighting Systems

This may be provided to enable normal activities to continue in the event of failure of the normal mains supply. Central battery systems, uninterruptible power supplies or standby generators can be used to provide lighting for extended periods.

This ensures that all means of escape can be safely and effectively used at all times. Emergency escape lighting may be subdivided into three areas: Escape Route Lighting To enable safe exit via the main escape routes from a building.

To provide illumination enabling people to reach a main escape route.

To ensure the safety of people involved in a potentially dangerous process or situation and to enable proper shut down procedures for the safety of the operator.

Bearing in mind the different types of lighting required, it’s vital to consider the premises layouts and usages, escape routes etc and also to think about commissioning and maintenance of the system, to design an emergency lighting system which will be effective and efficient. The type and category of system used will depend on the size and function of the premises. The system should provide for the safe movement of people along the escape routes and through the exits. The emergency lighting design should take account of individual lamp luminaire failure, mounting height, spacing, additional escape lighting and emergency signs.

Exit signs are required at all exits, emergency exits and along escape routes. Directional signs are also required to direct people to the emergency exit routes. More information about emergency exit signage.

Regular maintenance and testing required to ensure that the system will perform as required in the event of an emergency. Servicing should be carried out to a planned schedule, with supplies of consumables (lamps, batteries etc) available for immediate use. All testing should be carried out at times of minimal risk, and test, results and corrective actions should be recorded in the site log book, to comply with current legislation.
