Electric shock in Construction
Electric shock remains a significant hazard on construction sites, often resulting from overlooked equipment maintenance or improper handling of power sources. Prioritizing electrical safety is essential for protecting your crew and maintaining a secure, productive work environment.
About 100% of related real accidents concentrate in these types.
Key prevention
- Conduct regular visual inspections of all power cords and tools to identify and remove damaged equipment before use.
- Ensure all temporary power outlets are equipped with ground-fault circuit interrupters to prevent severe shocks in damp conditions.
- Establish a strict policy that only qualified personnel are permitted to perform electrical repairs or modifications on-site.
- Maintain clear distances from overhead power lines when operating heavy machinery or using ladders and scaffolding.
- Provide comprehensive training to all workers on identifying potential electrical hazards and the correct procedures for reporting faulty equipment.
