The risk factors for underwater welding and cutting are characterized by the fact that arcs or gas flames are used underwater, which is more dangerous than welding in the atmosphere or general diving operations. Common accidents in underwater welding and cutting operations include electric shock, explosion, burns, burns, drowning, bruising, diving or suffocation. The causes of the accident are roughly as follows: (1) Ammunition, fuel containers and chemical dangerous goods are often found in ships or other objects that sink into the water. The situation is not detected before the welding and cutting, and an explosion occurs during the welding process. (2) Accidents caused by tempering and burning of hot metal droplets, scalding operators, or burning of diving equipment such as gas supply pipes and diving suits. (3) Electric shock due to insulation damage or improper operation. (4) Bruises, crushing, crushing and even death accidents occurred in the collapse of underwater components. (5) Due to the burning of gas supply pipes and diving suits, electric shocks or sea winds and waves may cause drowning accidents. NANTONG DONOR COMPANY LTD , https://www.ntdonglan.com
