Electric arcs are one of the leading causes of death in power plants, but what exactly is an electric arc? And do you know how our fabrics can protect you from it?
The electric arc is the electric discharge formed between two electrodes subjected to a potential difference. It can reach temperatures up to 7000 Fahrenheit and expose the skin for only 0.1 seconds to 203 degrees Farenheit, which can cause third-degree burns.
Arc flash can happen due to some of the following causes:
- Condensation (humidity in the assembly of the equipment)
- Contamination (dirt in the electrical panel)
- Premature deterioration of insulating materials
- Defective contact points, among other things
- Even in a spray paint booth, an explosion can occur caused by improper electrical appliances or static electricity that ignites flammable vapors or dust
Some of the consequences are:
- Complete destruction of the electrical panel. It may be that the side walls, doors, and cover are ejected when an explosion occurs due to an internal arc.
- Brain contusions
- Hearing loss
- broken bones
