1. It is strictly forbidden to introduce oxygen into the room to adjust the air in the operating place.
2. Before the welding operation, the welding environment inside and outside the workplace must be carefully investigated. The welder should check whether the outdoor buildings or other structures have any influence on the indoor dynamic welding and cutting, and whether there are flammable and explosive combustible substances in the room. , If necessary, the indoor gas should be sampled and analyzed first, and the welding operation can only be carried out after the laboratory test is qualified and confirmed to be safe.
3. Electric welding machines, oxygen cylinders, and acetylene generators are not allowed to be placed in rooms where hot-fire welding and cutting are performed. Before welding, carefully check whether the oxy-acetylene pipeline and welding and cutting torches are leaking, and strictly prevent explosion accidents caused by the accumulation of oxy-acetylene gas in the room. Take the torch out of the room. And open all doors, windows or valves to keep the air circulation in the work space as much as possible, and use forced mechanical ventilation if necessary.
4. When welders use welding and cutting equipment to carry out electric welding operations, the environment of the welding and cutting place should be kept dry, and the protective equipment used must meet the safety requirements. When welding in metal containers, low-voltage lighting should be used for lighting equipment, and welders are not allowed to touch metal containers with their heads, backs, etc. or parts without edges.
