Truss and Batten Installation

Current Provisions: 
Roof trusses and battens may be spaced at up to 900mm centres to reduce risk of internal falls (section 6.6 of the Victoria Code*). * Worksafe Vic Code of Practice: Prevention of falls in housing construction.
New Provision and Date of Effect: 
01 January 2012

If internal fall protection cannot be provided, truss and batten spacing should be reduced to minimise the risk of internal falls by one of the following methods.

  •  If truss spacing does not exceed 600mm centres, the batten spacing must not exceed 900mm centres
  • If the truss spacing is greater than 600mm but not exceeding 900mm centres, the batten spacing must not exceed 450mm centres
  • If the truss spacing exceeds 900mm and the batten spacing exceeds 450, other fall protection must be provided.
