Rise in Electrical Shock Incidents Prompts Safety Warning for SA Residential Construction Workers

Summary: SafeWork SA has issued a warning to residential construction workers across South Australia after recording a surge in electric shock incidents linked to overhead powerlines. Employers and contractors must maintain safe clearance distances to prevent hazardous contact between workers, plant equipment and power infrastructure.

SafeWork SA urges residential construction workers to keep a safe distance from overhead powerlines following a spike in electrical shock incidents. The regulator says it has been notified of numerous electrical incidents in recent months, highlighting ongoing hazards on residential sites across the state.

Two electric shock incidents involving apprentices were reported last month, according to SafeWork SA. These cases add to a broader pattern of electrical hazards affecting the residential construction sector, prompting renewed advice for builders and site supervisors.

What SafeWork SA Says About the Risk

SafeWork SA said, "While no serious injuries were sustained in any of the recent incidents, they all had the potential to cause major trauma or death." This statement underscores the real risk posed by overhead powerlines on construction sites, even when outcomes appear minor.

"SafeWork SA and the Office of the Technical Regulator (OTR) are reminding builders and contractors in the residential construction sector to ensure workers and plant do not encroach safe clearance distances." Maintaining proper clearance remains central to reducing hazardous exposure near live power infrastructure.

Why Powerlines Pose Ongoing Hazards

Overhead powerlines present a persistent risk on residential build sites, particularly where cranes, scaffolding or elevated plant operate close to power sources. Rooftop trades, including those installing solar panels, face heightened exposure to hazardous conditions when clearance distances are not properly assessed beforehand.

Apprentices and newer tradespeople often carry greater risk due to limited site experience, making clear communication of hazards essential for supervisors and employers alike. SafeWork SA's advice emphasises proactive hazard identification before work near powerlines begins.

Practical Advice for Reducing Risk

• Identify overhead powerlines during pre-start planning and mark exclusion zones clearly.
• Ensure plant operators and workers understand minimum clearance distances before mobilising equipment.
• Provide targeted training for apprentices working near power infrastructure or solar installations.
• Consult SafeWork SA guidance and relevant electrical safety standards for site-specific advice.
• Review clearance protocols regularly, especially on sites where solar installation work is underway.

Following this advice helps reduce hazardous encounters and supports safer outcomes across residential construction projects. Employers should also consider referencing a formal Electrical Safety Policy to reinforce clearance requirements and hazard controls on site.

Resources for Construction Employers

Businesses seeking practical tools to manage electrical hazards can reference an Electrical Safety Audit Checklist for Construction Sites to support routine inspections and compliance checks. Similar guidance is available through the Electrical Safety Checklist for New Zealand workplaces operating under comparable standards.
