Construction workers face various hazards while performing their duties, including working with electricity. High-voltage strikes can cause severe injuries, disabilities, and even death. It is, therefore, essential for construction workers and their supervisors to understand the risks involved and take the necessary precautions to prevent such incidents. This article provides an overview of high-voltage strikes, their causes, prevention measures, and safety tips for construction workers.
High-voltage strikes are electrical injuries caused by contact with electrical energy of over 1000 volts. Construction workers may come into contact with high-voltage energy when working near power lines, transformers, electrical panels, or equipment. The severity of the injury depends on the intensity and duration of the electrical current and the body part affected.

Causes of High-Voltage Strikes
The following are the common causes of high-voltage strikes:
Contact with Power Lines
Construction workers working on scaffolds, ladders, or cranes may come into contact with overhead power lines. They may also accidentally touch live wires while installing, repairing, or replacing electrical components.
Contact with Electrical Equipment
Working with electrical equipment that is not de-energized, locked out, or tagged out can lead to electrical shock. Using damaged or faulty equipment, improper wiring, or improper grounding can also result in high-voltage strikes.
Rain, snow, and other environmental factors can increase the risk of high-voltage strikes. Wet or damp surfaces can conduct electricity, and lightning can also cause electrical injuries.
Prevention is key to avoiding high-voltage strikes. The following measures can help prevent electrical injuries:
Construction workers must receive proper training on electrical safety, including the hazards of working near high voltage energy, use of personal protective equipment, lock-out/tag-out procedures, and emergency response.
Use of Personal Protective Equipment (PPE)
PPE such as insulating gloves, rubber boots, hard hats, and safety glasses can help protect workers from electrical injuries. Workers should ensure that their PPE is in good condition and properly fitted.
Before working on electrical equipment, it is crucial to de-energize and lock-out or tag-out the equipment to prevent accidental energization. This will require testing equipment to ensure it is de-energized.
Proper grounding can help prevent electrical injuries by providing an alternative path for the electrical current. Workers should ensure that electrical equipment is properly grounded and that the grounding system is in good condition.
Avoiding Overhead Power Lines
Workers should be trained on the safe distances to maintain from overhead power lines, especially when operating cranes, scaffolds or other equipment. Signage should be placed to indicate the presence of power lines.
Safety Tips for Construction Workers
Construction workers can take the following safety tips to minimize the risk of high-voltage strikes:
Stay Alert and Focused
Construction workers should always stay alert and focused when working near electrical equipment or power lines. Distractions can cause accidents.
Be Mindful of Your Surroundings
Workers should be aware of their surroundings and look for overhead power lines, electrical panels, or transformers. They should avoid working near them if possible.
Inspect Equipment Regularly
Construction workers should inspect electrical equipment before use to ensure it is in good condition, and avoid using damaged equipment.
Use Tools Safely
Tools should be used safely, and workers should avoid touching metal parts of tools when they are energized. Tools should be appropriately insulated.
Properly Store and Label Chemicals
Workers should store and label chemicals appropriately and avoid placing them near electrical equipment or power lines.
High-voltage strikes pose a significant risk to construction workers. The consequences of these incidents can be severe, leading to injuries or even fatalities. It is crucial for workers to receive adequate training and use proper personal protective equipment to minimize the risk of electrical injuries. Employers must also ensure that all equipment is properly grounded and de-energized before work begins.
In addition, workers should be aware of their surroundings and always inspect equipment before use. They should also avoid using damaged tools and avoid working near power lines, electrical panels, or transformers. By following these safety tips, workers can reduce the risk of high-voltage strikes and prevent accidents.
- What should I do if I witness a high-voltage strike?
If you witness a high-voltage strike, call emergency services immediately and do not approach the victim or touch any electrical equipment.
- Can high-voltage strikes cause permanent disabilities?
Yes, high-voltage strikes can cause permanent disabilities such as loss of limbs, nerve damage, or burns.
- Is it necessary to receive training on electrical safety?
Yes, it is essential to receive training on electrical safety to understand the hazards of working with electricity and how to prevent electrical injuries.
- What should I do if I come into contact with live electrical wires?
If you come into contact with live electrical wires, do not touch anything else, and try to move away from the wires if possible. Call emergency services immediately.
- Who is responsible for ensuring electrical safety on a construction site?
Employers are responsible for ensuring electrical safety on a construction site by providing proper training, and personal protective equipment, and ensuring that equipment is properly grounded and de-energized.
