HAZMAT diving is highly technical, requires special equipment, and is all about maintaining control in highly hazardous environments such as nuclear and hydrodynamic plants, industrial plants, and chemical manufacturing areas, really anywhere that involves bio-hazards underwater. Divers are often tasked with the containment, clean up, and disposal of hazardous materials. HAZMAT requires an array of specialized diving equipment that seals the diver’s body completely from waterborne elements.
