Safety lighting is the next generation in lighting control. It gives building operators the ability to ensure that occupied areas provide the occupants with safe and adequate lighting at all times.
The basic idealism behind safety lighting could be defined in the following statement:
Emergency Lighting + Lighting Control + OH&S = Safety Lighting
For safety lighting to work adequately it needs to encompass a number of special requirements:
Individual feedback from all lighting devices including normal and emergency devices. (Feedback needs to include lamp and device status)
The ability to set minimum lighting levels in all areas
The ability to set emergency lighting levels in all areas
Flexible control system
The essence of safety lighting
In essence a safety lighting system will provide the minimum lighting required to ensure workers can:
Evacuate the building during an emergency (covered by the emergency evacuation standards)
Carry out normal day to day activities without risk.
Many systems today only offer the ability for building occupiers to evacuate the building in an emergency situation where the power may be disconnected. This does not cover situations where the lighting has failed due to lacking maintenance, power surges or other unforeseen circumstances. Below are some examples of safety lighting.
