Exit Signs & Emergency Lighting.

Following the information from the international standard (ISO 38641-1) Exit Signs are being slowly replaced with pictogram signs.  All new buildings or referbishments  will be changed from the word EXIT to the new running man pictogram.  This applies to all projects with building approval after may 2006.

An exit sign must be visable to persons approaching the exit and must be installed above or adjacent to each door  (Ref BCA E4 MS SA76 Schedule 3.3 & AS 2293).

Emergency Lights.  (Refs MS SA76 Schedule 3.4,  BCA E4.2,  AS 2293 SA OHS&W Regs 1985 SA).

The BCA requires that an Emergency lighting system must be installed in every fire isolated stairway, fire isolated ramp or fire isolated passageway and in every storey of a Class 5, 6, 7, 8 or 9 building where the storey has a floor area of more than 300 m2.

 

Emergency lights and exit signs are both subject to monthly, 6 monthly and 12 monthly maintenance as perscribed in AS 2293.  Exit signs and emergency lights are installed in buildings to guide the building occupans to the exits in the event of an emergency.  They should also remain illumiated for 90 mins in the event of the building suffering a power failure.

 

This PPT shows some typical Active and Passive systems that you could find in an average building . Dont forget that the systems fitted to buildings would depend on a number of factors for example, the classification, the height, the age, Floor area and if there are any Alternitive solutions.
