Explosion-proof equipment is specially designed to operate safely in hazardous environments where flammable gases, vapors, or dust may be present. This type of equipment is built to contain any explosion that might occur within its housing, preventing the ignition of surrounding materials. Common applications include oil refineries, chemical plants, and mining operations. The construction of explosion-proof equipment involves robust materials and sealed enclosures that can withstand high pressure. Standards for this equipment are often set by organizations like the National Fire Protection Association (NFPA) and the Underwriters Laboratories (UL), ensuring that it meets strict safety regulations for use in dangerous settings.
