|Combustion or Oxidation Can Create a Hazardous Atmosphere in a Confined Space.|
|Combustion (welding, heating, gasoline or diesel engines, cutting and brazing) and oxidation (rusting) can create hazards.
Oxygen Deficiency – Oxygen is consumed by the combustion or oxidation process, or displaced by the combustion products.
Toxis Gases – Carbon Monoxide is produced by incomplete combustion. Other gases can be produced by the material heated; i.e., cutting cadmium plated bolts with a torch releases a toxic vapor.
