Safty Tips for Construction Worker High-Voltage Strikes (2023)
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.
Environmental Factors
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 Measures
Prevention is key to avoiding high-voltage strikes. The following measures can help prevent electrical injuries:
Proper Training
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.
De-Energizing Equipment
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
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.

Conclusion
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.
