Hazards Associated with Electrical Work
Working with electricity can be dangerous, and accidents can have severe consequences, including injury or even death. Technicians, electricians, engineers, and maintenance workers all know very well the risks associated with working with electricity. As a result, NFPA 70E, known as the Standard for Electrical Safety in the Workplace, offers guidelines for reducing electrical hazards in the workplace. The following are some of the hazards associated with electrical work:
Electrical shock is one of the most common accidents associated with electrical work and can happen when a person touches a live electrical wire or electrical equipment that is faulty. Electrical shock can cause severe injuries and can even be life-threatening. The severity of the injury depends on the amount of electrical current that passes through the victim’s body, the path the current takes, and the duration of exposure. According to the Occupational Safety and Health Administration (OSHA), the minimum current a person can feel is 1 milliampere (mA), while currents greater than 75 mA can be fatal.
When electrical current passes through the body, it can cause severe burns, both internal and external. The severity of the burns depends on the type and duration of the electrical current, the path the current takes, the voltage, and the resistance of the victim’s body. Electrical burns can cause damage to the skin, muscles, and bones, and can lead to complications such as nerve and tissue damage, infection, and even amputation.
Electrocution occurs when a person is exposed to electrical current of sufficient strength to cause death. Electrocution can occur due to direct contact with live electrical wires, accidental contact with electrical equipment, or contact with electrical sources through a conductive material. Electrocution is a severe hazard associated with electrical work and requires proper safety measures to avoid.
Fire and Explosion
Electrical equipment and wiring can produce heat, which, if not well controlled, can lead to fires or explosions. Short circuits, overloaded circuits, ground faults, and other electrical faults can lead to electrical fires or explosions, causing severe property damage, injuries, and fatalities, and creating enormous financial losses.
Falls, Trips, and Collisions
Electricians and other workers in the electrical industry often work at heights, which can lead to falls or trips. Falls from heights and other accidents can lead to severe injuries or fatal accidents. Workers can avoid falls and mitigate trips by following safety guidelines and using proper protective equipment, such as harnesses, boots with good traction, and hard hats.
Working with electricity is inherently dangerous, and electrical hazards can cause severe injuries or fatalities. Hazards associated with electrical work include electrical shock, electrical burns, electrocution, fires, explosions, falls, trips, and collisions. These hazards can be minimized by following guidelines and safety standards established by the NFPA 70E Standard for Electrical Safety in the Workplace. Individuals working with electricity have a personal responsibility to stay vigilant and protect themselves from electrical hazards while on the job.
Personal Protective Equipment (PPE) Requirements

PPE is a critical element of electrical safety and must be selected based on the hazard assessment. It is the employer’s responsibility to provide PPE to their employees and ensure that it is appropriate for the task at hand.
The standard defines six categories for PPE based on the level of arc flash hazard. They are to be labeled PPE Category 1, 2, 3, 4, and so on. The selection of PPE for each category varies based on the energy level measured in calories per square centimeter (cal/cm2). The higher the category, the greater the energy level and the more significant the risk. For example, a Category 1 PPE may require cotton undergarments while a Category 4 PPE may require full arc flash suits, gloves, and hood that weighs over 50 lbs.
The PPE requirements outlined in NFPA 70E are designed to provide adequate protection to the worker. The minimum basic protective gear required by NFPA 70E includes eye protection, hearing protection, hand protection (gloves), head protection, and foot protection. Eye protection is required for all tasks including opening an electrical panel or turning a breaker back on. Under certain circumstances, face shields, respiratory protection, and fall protection may also be necessary.
In addition to the PPE categories, NFPA 70E provides a detailed explanation of the condition, limitations, selection, use, and maintenance of PPE. It is important to note that the last point is critical. Inappropriate use or failure to maintain PPE can lead to dangerous conditions that could cause injury or death to the worker.
The selection of PPE should take into account the level of hazard, the degree of risk, and the task the worker is performing. The type and condition of tools used in the task should also be considered. NFPA 70E recommends the use of insulated tools that are tested and classified for the job’s specific voltage level. Air testing and calibration are also necessary to ensure the conditions of the PPE meet the required level of protection.
The most important thing for electrical safety is ensuring that workers understand why and how to properly use PPE by providing training on their proper use and care. The training program should cover the following:
- The hazards of working around electrical energy
- The importance of PPE in reducing electrical hazards on the job
- The use of PPE: how to put it on, how to adjust it, and how to remove it properly
- The care and maintenance of PPE: how to keep it clean, how to inspect it for wear and damage, and how to store it
Employers must also ensure that the PPE is appropriate for the task and has been tested and certified by an independent testing laboratory. The ANSI Z87.1 standard outlines the minimum requirements for eye protection to be deemed safe. Similarly, the ASTM F1506 and ASTM F2178 standards established minimum requirements for protective clothing and gloves for workers exposed to electrical hazards. These standards provide manufacturers with guidelines to make sure that the product meets basic safety standards. It is important to note that the use of high-quality PPE reduces the risk of injury and makes the worker more comfortable and productive, and employers must always ensure the PPE provided is appropriate and adequate for the task.
In conclusion, PPE is an essential element of electrical safety. The use of the recommended protective gear and training on their use and care is vital to ensure that workers are protected from electrical hazards while performing their job. Employers must provide the appropriate PPE, ensure it is selected, and maintained appropriately. By following the guidelines of NFPA 70E, employees can work safely around electrical energy and reduce the risk of injury or death due to electrical hazards.
