Systems
Individual fall-arrest systems (IFAS) are intended to arrest a falling person safely and reduce the impact of the fall. If using IFAS, training and supervision is essential. The safe and correct use of IFAS relies on many factors, including the design and availability of substantial engineered anchorage points. IFAS have limited application in housing construction because:
    * they require ongoing supervision and are awkward and cumbersome to use on residential roofs
    * they are generally appropriate for work at heights over 6.5 metres (workers in residential construction would generally strike the ground before the system properly deploys)
    * it is often difficult to achieve the minimum required 15 kN anchorage point rating on a timber roof (particularly when only partially completed)
    * workers are susceptible to tripping caused by the lanyard
    * they require a rescue procedure to stop the fallen worker from succumbing to suspension intolerance.

6.3 Safety nets
Safety nets can provide a satisfactory means of protection while allowing workers maximum freedom of movement.
An internal safety net can be effectively used over stairwell openings.

Safety Net Checklist

If safety nets are used, you should ensure that:
          safety nets are securely anchored before any work starts
          safety nets are constructed of material of sufficient strength to catch a falling person or debris
          elevating work platforms (e.g. a cherry picker or scissor lift) are used for the installation.
  If this is not possible, scaffolding and fall-arrest systems must be used
          safety nets are hung as close as is practicable to the underside of the working area, but no more than 2 metres below the working area
          perimeter safety nets are installed where there is no edge protection to prevent workers
  falling over the edges
          the safety net has sufficient tension and clearance to prevent a falling person contacting any surface or structure below the net
          material is not allowed to accumulate in suspended safety nets
          no welding or oxy cutting is performed above safety nets
          safety nets are not used in an environment that exposes them to damage from chemicals,
  sun or heat
          safety nets are inspected, particularly after installation, relocation or repair
          safety nets are stored correctly in dry, shaded areas with good air circulation.

7.             USE OF PORTABLE LADDERS AND ADMINISTRATIVE CONTROLS

Ladders are used extensively in the housing construction industry. However, many falls take place when people are working from ladders. In addition, when using a ladder:
    * the working width and movement is limited
    * the time involved in moving and setting up ladders is often underestimated when planning work
    * the working position on ladders is often uncomfortable (the need to stretch
