Also, there is the ever-present chance of fire. Fires caused from welding and cutting cost <br /> a hundreds of thousands of dollars annually. You just can't substitute oxygen for air to <br /> produce artificial ventilation. Air is usually supplied by a forced draft to all such <br /> operations. <br /> E <br /> There is no good reason at all for taking a chance by welding or cutting in a confined area j <br /> that does not have proper ventilation. Remember that oxygen does not burn, but it does <br /> support combustion. Do proper testing of atmosphere fit confined space areas. <br /> Responsibility for safety in welding and cutting goes all the way up and down the line from <br /> Superintendent, Foreman and Operator. Everyone concerned should do their share in <br /> making these operations safe. <br /> Accident records indicate that certain conditions and acts caused most cutting and welding <br /> accidents. Precautions for preventing welding and cutting accidents are: <br /> 1. Before you start to weld or cut in confined spaces, be sure there is proper ventilation. <br /> Follow all confined space requirements. <br /> 2. Keep a proper type fire extinguisher within reach at all times. <br /> 3. Use only a wrench of the proper size on cylinder apparatus and keep all connections <br /> right. <br /> 4. Keep oil away from oxygen valves. <br /> 5. Inspect all work areas and place required shields and welding blankets before welding <br /> f or cutting; see that there are no explosives, dangerous gases or flammable materials <br /> nearby. <br /> 6.
