Arcing harm to the human body what are the factors

An electric arc is the discharge of a current through a gas, and an arc can occur when a sufficiently strong current is passed through the ionized air. The arc can cause an explosion, usually lasting less than a second, but can release significant amounts of radiant energy that can ignite and / or melt everyday-wearing garments. Arc temperature is very high, the core temperature up to 20000 ℃ (twenty thousand degrees Celsius), the arc may lead to many secondary hazards such as high temperature gas, molten metal splashes, pressure waves. High-decibel noise and shock hazard may also occur.
        Although it may be only a fraction of a second, but the damage may continue for life. Every day, many employees of power companies are exposed to the dangers of arcing, such as electrician, wireline maintenance inspector, power plant worker, operator of substations and transformers, and late-night maintenance personnel. The hazards associated with electric arcs include:
    Shocked
        The direct contact of the arc to the body can result in electric shock or serious burns. In fact, even flame-retardant protective clothing can not protect workers from the risk of electric shock.
    2. Serious burns due to electric arc
        Workers do not have to be hit by an electric arc to get hurt. Electric arc can produce high fever. This high temperature allows the arc to melt the tool in a short period of time so that everyday clothing fires without fire. Once worn, the clothes will continue to burn and cause further serious damage to the wearer.
    3. Clothing burst causing serious burns to employees
        The explosion or impact of an electric arc can burst everyday clothing and cause the worker's body to be exposed to heat, flames and melted equipment.
    4. Synthetic fiber underwear melting causes serious burns
        The high heat generated by the electric arc can melt the underwear made of synthetic fiber material, even in the absence of a porridge burn on the outer garment.
    5. Continued fire caused serious burns
        The heat of the arc is sufficient to cause a fire and cause more explosions. For example: An electric arc can burn a transformer or explode a nearby building.
        In general, the incident energy increases with the fault current and duration, as well as the working environment (open air compared to sealed air). It is important to understand that the duration of the arc is a key factor in the burn rate of a worker. Because arc injection energy is a function of arc duration and arc current, a low fault current, long duration, can result in a greater degree of burn than a high fault current, with a short duration of severity. Even a relatively low voltage system (480 / 277V) creates a stable arc of 3-4 inches and lasts longer.
        Arc explosions have many variables, so although the statistical analysis can be used to calculate the possible damage caused by the arc current, in actual events, the result of the hazard may be higher or lower than the result of the calculation. Due to the unpredictable nature of electric arc explosions, electricians are even more in need of protective clothing in areas where the arc energy may reach.
