Terms and Norms on Safety in Welding Part 4

terms and norms on safety in welding part 4

If you are using cylinders of compressed gases must comply with established safety precautions: do not throw bottles, do not install them near heat sources, do not store with oxygen cylinders and combustible gas, cylinders stored in upright position. The freezing of moisture in the cylinder with pressure reducer of CO2 to warm him only through a special electric heater or obkladyvaya rags soaked in hot water. It is strictly forbidden to warm any compressed gas cylinders with an open flame, as it almost inevitably leads to the explosion of the cylinder.

In the production of welding on the tanks, previously used, requires clarification of the type of stored product and the presence of its residues. Thorough cleaning of the vessel is required from the remnants of food and 2-3-fold washing with 10% alkali solution, is also required follow-blowing with compressed air to remove odor, which can be harmful to act on the welder.

It is strictly forbidden purged with oxygen tanks, trying to do that sometimes, as in this case, the ingress of oxygen to the skin, clothing and welder for any open source of fire ignition causes intense wear and leads to fatal burns.

Danger of explosion exists when performing work in areas that have a large amount of powdered organic matter (food meal, peat, coal). This dust at a certain concentration can produce explosions of great strength. In addition to thorough ventilation for welding work in these areas requires a special permit fire.


Preventing fires from the molten metal and slag. The danger of fire is for this reason there is in those cases when performing welding for metal, wood, or the closing izolirovochnye combustible materials in the timber forests of flammable materials, etc. All of these options for welding should not be allowed.

Prevention of injuries associated with assembly and transport operations (mechanical injury type). It is important to the introduction of complex mechanization and automation, which reduces the risk of injury of this kind.

The main causes of injuries in the assembly and welding: the lack of vehicles for transporting heavy parts and products, faulty vehicles, failure of lifting appliances, faulty tools: hammers, hammers, wrenches, chisels, etc., the lack of protective eyewear when cleaning the welds on the slag, lack of clothing and other protective equipment.

Safety measures in this case: all of the tools and instruments should be checked periodically, lifting work should produce persons having special instructions, the workers should be required to comply with all safety regulations, including work clothing, gloves, the use of individual ventilation systems (where necessary), etc. It is important to the introduction of complex mechanization and automation, which reduces the risk of injury of this kind.
