When most people think about hazards at construction sites, the first thing that comes to mind is falling from great heights, inhaling dust particles or being struck by falling objects. Many people easily overlook electrocution because they hardly associate construction with exposure to electricity.
In reality, construction workers encounter electricity quite a bit, and this comes with a potential electrocution hazard. In fact, electrocution is one of the Fatal Fours in construction accidents, often resulting in severe injuries or fatalities. Understanding the most common scenarios where electrocution can occur is crucial for implementing effective safety measures.
Contact with overhead power lines
Overhead power lines are a significant hazard on construction sites, especially for workers operating:
- Cranes
- Scaffolding
- Ladders
- Aerial lifts
These lines often carry high-voltage electricity, making even indirect contact potentially fatal. For instance, a worker using a metal ladder that accidentally touches a power line could complete the circuit, leading to electrocution.
Faulty or damaged electrical equipment
Power tools, extension cords and other electrical devices are staples on construction sites. Unfortunately, when they’re damaged or improperly maintained, they can become hazardous. Electric devices can electrocute construction workers due to:
- Exposed wires
- Broken insulation
- Malfunctioning machinery
Additionally, using tools in damp conditions amplifies the risk of electrocution.
Improper grounding
Grounding is essential for directing stray electrical currents safely into the earth. Construction workers are at heightened risk of electrocution when grounding is:
- Absent
- Insufficient
- Improperly installed
For example, portable generators or temporary electrical systems often require specific grounding procedures that, if overlooked, can lead to dangerous situations.
Excavation or digging near underground power lines
Underground power lines are another common but often overlooked electrocution hazard at construction sites. Workers operating heavy machinery like excavators or digging trenches may inadvertently strike buried electrical cables and get electrocuted. Such incidents can occur due to a lack of proper site planning or failure to locate underground utilities.
Electrocution hazards are pervasive on construction sites, but with adequate awareness, training and preventive measures, they can be minimized. That said, construction workers who get electrocuted at construction sites should consider pursuing workers’ compensation. Hands-on legal support can help ensure they secure sufficient compensation regardless of the circumstances leading up to their electrocution.
