The main injuries caused by arcs to people are as follows:
1. Death by electric shock. When workers are directly exposed to electric shock, it may cause electrocution or severe burns. In fact, even fire-resistant protective clothing cannot prevent workers from being injured. Workers are protected from the risk of electrocution;
2. Severe burns caused by burning clothing, workers do not necessarily need to be exposed to the arc to be injured. The radiant heat generated by the arc can melt tools, daily clothing, etc. in a very short period of time. Fire and burning. For example, cotton clothes and polyester clothes will catch fire and burn without flame. Once such clothes are ignited, they will continue to burn and cause fatal injuries to the wearer;
3. Clothes burst and cause serious injuries. Burns, the explosion or concussion force generated by the arc will cause daily clothing to burst, and the worker’s body will be directly exposed to high heat, flames 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 garment does not burn, the high heat generated by the arc is enough to melt underwear made of synthetic fiber materials. Since the underwear is close to the skin, it will cause serious burns to the wearer. Serious, even fatal, injuries.
Overseas, many examples 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 City Textile is mostly made of cotton. According to the American ASTMF 1959 test method, its ATPV value can reach Level 2, which can meet the arc-proof requirements as a single-layer protective clothing and has good flame retardancy. performance.
