High Voltage: Arc Flash Training Your Employees Need to Know

According to the Occupational Safety and Health Administration (OSHA), 350 people are killed by electricity each year. Even for experienced electrical workers, a high voltage is dangerous. Electrical hazards can be experienced in the office, warehouse, or on the production floor. What are some of the dangers of working with high-level electrical output? How can you keep your employees safe?

Dangers of High Voltage

High voltage is any amount of electrical output that could cause harm to a living organism. Power lines, circuit boxes, and power supplies for large equipment channel enough power to cause serious injury.

Electrical contact doesn’t just happen when the power supply is touched or mishandled. High voltage lines, attracted by an incendiary in the area, can shoot an arc through the air to ignite its target. Fire is one of the biggest concerns from an arc flash. Electrical fires spread quickly and can be difficult to control. Travelling along the wires in the walls of the building, these fires can reduce a structure to ashes in moments. Electricity from an arc flash can heat up the metal in pipes and fences, causing fires to break out far from the source. According to OSHA, the most common results of an arc flash are:

  • Heat up to 35,000 degrees F
  • Burns to skin and clothing
  • Fire
  • Flying objects that may cause damage to people or property
  • Intense pressure from blast
  • High-decibel sound blasts

In the body, high levels of electrical current can cause severe and often irreversible damage.

  • Electrical burns can damage body tissues. Third-degree burns on the contacted skin are possible. Longer exposure can cause internal damage. If large areas are affected, the victim may need transplants of the skin or other organs. Damaged limbs may be amputated.
  • Electrical charges disrupt heart function. Mild shocks may cause temporary arrhythmia. More prolonged exposure can damage the heart muscle or even cause full arrest.
  • Sound waves from arc flashes can damage delicate inner ear structures. This damage may be permanent.

The severity of the damage a worker receives depends on a number of factors like how close the victim was to the blast, the type of personal protective equipment they were using, and the duration of the exposure.

Protecting Your Employees

You can help your employees avoid electrical injuries by establishing good safety practices.

  • De-energize power sources when servicing equipment.
  • Provide adequate personal protective equipment for workers accessing high voltage areas.
  • Encourage the use of insulated tools and clothing to protect the skin from conducting electrical currents.
  • Ensure proper grounding of circuits and outlets to prevent sparks.
  • Keep conductive metals away from high voltage lines or have them insulated to avoid arcs.
  • Provide a written safety plan that details how to work in high voltage environments.

A formal training is the best way to prepare your employees for working in high voltage areas. A group training offers many benefits.

  • Your employees will be able to motivate each other through the training.
  • Holding one group training ensures none of your employees misses out on important information.
  • Training led by a qualified instructor give your employees the opportunity to get reliable answers to their questions.

The best way to protect your employees from electrical injury is to give them the knowledge they need to keep themselves safe. A formal group training from an experienced instructor is the fastest way to make that happen.
