Casting: shaping procedure

General Hazards provoked by aerosols or gases during casting processes

Almost all casting processes for almost all materials provoke aerosols and especially smoke and gases due to the high temperatures applied. These contaminants pose hazards, which should not be underestimated. These can be discriminated into general and specific dangers. The specific dangers are:

  • risks of fire and explosions,
  • general long-term health hazards,
  • generally lowered product and production quality
  • loss in capital goods, especially by soiling of facilities/workshops.

 

Specific (health) dangers through contaminants

The (liquid) materials used are generally complex mixtures, which consist of several components. Due to the high temperatures these mixtures are in part chemically transformed and new components develop (e.g. residual substances or gases), which pose a threat to health:

  • chronical bronchitis and lipid pneumonia,
  • acute and chronical changes in the functioning of the lungs,
  • bronchial asthma and pulmonary fibrosis.
