The Hazard

• Welders can be exposed to gases, such a lead oxide fumes and carbon monoxide, that form from various types of welding. In many cases, these gases can present a serious health hazard. Lead oxide forms from doing welding work on surfaces that have paint or other substances containing lead. Carbon monoxide is created by the interaction of different chemicals that don't properly break down. These can cause such symptoms as dizziness, nausea and a dull headache.
  
  

Prevention/Solution

• Welders can prevent overexposure to gases by working in areas that are properly ventilated. They also should wear an air respirator to ensure there is enough oxygen. Gas containers for welding need to be kept out of confined areas, during use and storage.
  
  

Other Considerations

• When a welder is working in smaller spaces, it is essential to have a system in place to provide air to the worker. Due to the flammability of some gases, the welder also should wear flame-resistant clothing. These include pants, gloves and a leather apron.
