Modern fabrication practice , especially in the motor industry, can involve resistance welding through adhesives and sealants. During welding , fumes are generated that may be harmful to health and may be breathed by workers in work area. Currently, little is known about the concentration or composition of the fumes emitted, making it difficult to assess the risks to health arising from the activity, as required by the Control of Substances Hazardous to Health (COSHH)) Regulations 1999. Fume composition data was generated for resistance welding through a representative range of epoxy based adhesives and polybutadiene based interweld sealants, with the objective of developing sufficient information for comprehensive risk assessment. If possible, it was intended that a marker compound should be identified, to enable simplified monitoring of exposure to fumes in the workplace. Reports a number of conclusions.
