Arc flash suits are personal protective equipment (PPE) designed to protect individuals working with and near live electrical equipment from dangerous arc flashes.
Working in areas that have electrical circuits can pose a threat to the safety of employees. Sometimes workers need to deal with sophisticated electrical equipment that exposes them to arc flashes or electrical shocks.

What is an Arc Flash?
An arc flash is a type of electrical explosion that is caused by poor connection shielding along with malfunctioning caused by human error or a lack of maintenance. This results in a dangerous electrical charge moving through the air between voltage connections or to the ground.
Arc flashes are highly dangerous electrical events that can cause serious physical harm or even death.
When an arc flash occurs there is an extremely rapid rise in pressure and temperature in the surrounding area. Temperatures can soar up to 35,000 degrees Fahrenheit, which is close to 4 times the surface temperature of the sun.
Arc flashes can completely melt and destroy electrical equipment. Flying objects, molten copper and debris resulting from an arc flash can cause skin lacerations and shock to nearby individuals.
What is an Arc Flash Suit?
Arc flash suits are full-body protective clothing required for electrical workers to protect them from the heat and energy released during an arc flash. They include the following arc-rated components:
- Long sleeve shirt
- Face shield with wrap guarding
- Flash suit hood
- Hard hat liner
- Rain gear
- Leather boots
- Heavy-duty leather gloves with rubber insulation
- Safety glasses or goggles
- Hearing protection
- Hood Ventilation System (optional)
Arc suits are specially designed to meet the National Fire Protection Association (NFPA) PPE categories regarding arc flash incident energies.
