Safety information
Businesses and workers are reminded of their duty to identify hazards and manage risks to health and safety in accordance with the provisions of the Work Health and Safety Act 2011 and Work Health and Safety Regulation 2017.
Each year SafeWork NSW respond to incidents where workers have been killed or seriously injured from falls from a height. Many of these incidents involve falling through a penetration.
Workers in the Construction Industry are commonly at risk of falling from height; however, any worker working at height is at risk of falling.
Businesses are reminded to consider reasonably practicable control measures to manage the risk of falling from heights and working near penetrations including;
- Installing barriers, such as guard rails or covers, that are secured and labelled with warning signs in areas where penetrations are present
- Covering and marking, or installing guardrails around penetrations/voids
- Providing workers with safe means of access and egress to work areas
- Conducting a risk assessment prior to working near penetrations
