Paths of Travel to Exits

Safe egress along paths of travel to exits in a building especially in an emergency is fundamental for all buildings. Paths of travel to exits are always nominated as an essential safety measure by the building surveyor/ certifier in the essential safety measures determination/ schedule.

Building Code of Australia

Part of the Building Code of Australia D1 Provisions for Escape, clause D1.6 Dimensions of exits and paths of travel to exits, sets out the criteria for the designer (and occupier) to comply with. The BCA and Essential Safety Measures regulations require that paths of travel to exits must:

  • Have the unobstructed height as nominated
  • Have the unobstructed width as nominated
  • Not have any storage located in its path
  • Not be altered unless a building surveyor has issued a building permit/ approval
  • Not have trip or fall hazards

The following illustration depicts the minimum unobstructed width of a corridor in a Class 5 (office) building.

The following is a part extract of clause I1.1 for an Essential Safety Measure (as appeared in BCA 2013) known as paths of travel to exits:
