A Safety Guide to Electrical Hazards

An Informative Guide to Preventing Electrical Hazards


Are you aware of how many electrical hazards surround you right now? Electrical outlets and tools are common in most workplaces, and when used correctly, they pose little risk. However, even a 120-volt household current can be deadly. It’s crucial to manage health and safety by accounting for electrical hazards. Although electrical fatalities declined after the introduction of 29 CFR Part 1910 Subpart S in 2007, they have now leveled off, with 130 to 160 deaths occurring annually in the United States. It’s not just electrical workers who are at risk; the construction and extraction industries make up 44% of all electrical fatalities. Everyone needs to understand the power of electricity. In this guide, we will explore why electricity is dangerous, the consequences of electrical injuries, how electric shock becomes electrocution, who encounters electrical hazards, the safety standards that apply, where the National Electric Code fits in, and how to reduce or prevent electrical incidents.

Why Is Electricity Dangerous?

Electricity poses a serious hazard in the workplace due to its potential to cause both direct and indirect harm. Not only can electricity lead to electrical shock, but it can also cause fires and explosions, resulting in injuries such as electrical burns. Even seemingly minor injuries can have long-term consequences. For example, a survey conducted by Littlefuse Inc. revealed that many workers believe it’s safe to work with up to 500 volts of electricity. However, electric shock can occur even without direct contact with live electrical parts.

The Consequences of Electrical Injuries

Research has shown that electrical injuries, even if initially minor, can have long-term complications. Complications may include neurological, psychological, and cardiological effects such as seizures, memory difficulties, depression, and fatigue. The severity of electrical shock leading to electrocution depends on factors like voltage, internal body resistance, and the path and duration of the current through the body.

Common Electrical Hazards

Electric shock is the most common electrical injury, but there are other hazards to be aware of. These include arc flashes, thermal burns, and falls. According to OSHA, the most frequent causes of electrical injuries are contact with power lines, improper use of equipment, lack of ground-fault protection, and improper use of extension cords. Other potential electrical hazards include portable generators, exposed wires, faulty wiring, overloaded circuits, and inadequate grounding.

Who Encounters Electrical Hazards?

Electrical hazards can be encountered in any workplace, regardless of its setting. According to the Census of Fatal Occupational Injuries, electrical fatalities occur in both private residences and industrial job sites. Any individual working with or near electricity can be at risk if the appropriate safety measures are not followed.

Safety Standards for Electrical Hazards

OSHA has established standards to address electrical hazards in the workplace. These standards focus on the design and use of electrical equipment and systems. Safety professionals must ensure that electrical components chosen for use on a job site are constructed and installed to minimize the risk of danger. OSHA standards that apply to electrical hazards include 29 CFR 1910 Subpart S. Additionally, industry consensus standards like the National Electric Code (NEC) can provide guidelines for electrical design, installation, and inspections.

Reducing and Preventing Electrical Incidents

Preventing electrical incidents requires a combination of elimination, substitution, and engineering controls. Hazards should be eliminated or substituted whenever possible. Steps such as marking utility lines, de-energizing overhead power lines, using cordless power tools, and reducing voltage with transformers can help in this regard. Engineering controls, such as using well-insulated cables, protective conduits, and circuit breakers, can further reduce the risk of electrical incidents.

Overall, understanding the dangers of electricity, the potential consequences of electrical injuries, and implementing safety measures can help create a safer work environment for everyone. By being aware of electrical hazards and taking appropriate precautions, we can significantly reduce the risk of electrical incidents in the workplace.

Summary: An Informative Guide to Preventing Electrical Hazards

Electrical hazards are a common and potentially deadly risk in workplaces and homes. Despite safety regulations, electrical fatalities still occur, with construction and extraction industries being the most affected. It’s crucial for everyone to understand the dangers of electricity, as even low-voltage currents can cause severe injuries. Electrical hazards include electric shock, arc flashes, thermal burns, and falls. Long-term consequences of electrical injuries can involve neurological, psychological, and cardiological effects. To prevent electrical incidents, it is important to eliminate or substitute hazards, use engineering controls, and implement a lockout/tagout (LOTO) policy to de-energize electrical systems before maintenance or repairs.
