Emergency Lighting
  • Emergency illumination must be provided for a minimum of 1.5 hours in the event of failure of normal lighting.
  • Must provide initial illumination of on average at least one foot-candle and a minimum at any point of 0.1 foot-candle measured along the path of egress at floor level.
  • The maximum illumination at any one point can be no more than 40 times the minimum illumination at any one point to prevent excessively bright and dark spots
Lighting is often a neglected part of jobsite safety and is the cause of many fall incidents
  • Safety accidents can be reduced simply by following the lighting safety regulations
