The main harm caused by electric arc to people is as follows:

1. Death by electric shock. When a worker is directly exposed to electricity, it may result in electrocution or severe burns. In fact, even fire-resistant protective clothing cannot protect workers from the risk of electrocution;

2. For serious burns caused by burning clothes, workers do not necessarily need to be exposed to arcs to be injured. The radiant heat generated by arcs can melt tools in a short period of time, making daily Clothes catch fire and burn. For example, cotton clothes and polyester clothes will catch fire without flame. Once such clothes are ignited, they will continue to burn and cause fatal injuries to the wearer;

3. Severe burns caused by bursting of clothing. The explosion or concussive force generated by the arc will cause daily clothing to stretch and tear, exposing the worker’s body directly to high heat, flame or molten metal. (Such as: molten metal tools and equipment, etc.);

4. Drip melting of synthetic fiber underwear causes severe burns, even if the outer clothing does not burn. , the high heat generated by the arc is enough to melt underwear made of synthetic fiber materials, causing very serious or even fatal injuries to the wearer because the underwear is close to the skin.

Many examples abroad show that if these workers wear daily clothes at work, they will often suffer greater injuries. In fact, more than half of the arc-related injuries reported to OSHA (Occupational Safety and Health Administration) are caused by workers’ clothing burning.

Therefore, it has become a common safety standard requirement in European and American countries to assess the degree of danger in a specific working environment and provide workers with appropriate personal arc protective clothing. Personal protective clothing that counteracts the heating effects of arcs could improve accident victim survival rates by providing more time to escape and reducing the severity of burn injuries.

The arc-proof clothing produced by the city’s textile industry is mostly made of cotton. According to the American ASTMF 1959 test method, its ATPV value can reach level two, which can meet the requirements of single-use clothing. It meets the arc protection requirements of protective clothing and has good flame retardant properties.
