Working safely around penetrations and voids (May 2023)

In May 2023, SafeWork NSW responded to an incident where a young worker was fatally injured after falling through a penetration that was not adequately covered on a construction site.

Construction workers risk serious injury or even death when working at heights, and these risks are greatest when there are open penetrations and voids workers can fall through.

Businesses are reminded to consider reasonably practicable control measures to manage the risk of working near penetrations and voids.

A construction site with a void, covered by two wooden pallets.

The penetration was inadequately secured with two timber pallets screwed together.

Ensure:

  • penetrations and voids are considered during planning and design stages and suitable controls are installed before the penetration or void is formed
  • penetration / void covers are used that withstand the load of workers and materials
  • covers are secured in position and are clearly identified so they are not mistaken for construction material
  • guard rails are installed if the penetration / void is large or needed for temporary access
  • if using the penetration / void to access another level, consider using temporary stairs, or make sure your ladder extends one metre past the landing point
  • adequate training, instruction and supervision are provided to all workers
  • a site-specific safe work method statement (SWMS) is prepared before work commences, where the risk of falls is two metres or more.
