Welding and hot process fumes

We can competently assist in your compliance with the COSHH regulations by devising and undertaking workplace air monitoring surveys to measure personal exposures of your welding and hot cutting operators to welding fumes. In order to fully understand the risk to the health of your employees, it is necessary to carry out personal sampling for welding fumes and fine particulates. Chemical analysis of the fumes along with the exposure concentration data then provides a solid base for an adequate risk assessment of the welding process.

Our welding fumes assessment is carried out in strict accordance with the latest Health and Safety (HSE) guidance documents and International Standards (ISO). The assessment is carried out on a representative sample of the workforce to provide reliable exposure data. The collected information is then expressed as personal exposure levels for each exposure group and compared with the relevant exposure limits.

The assessment process briefly consists of:

  • Evaluation of employees’ exposure times, working patters and exposure groups;
  • Evaluation of existing fume controls such as General ventilation, LEV and RPE;
  • Evaluation of welding consumables, materials and welding techniques;
  • Personal sampling from a number of selected operatives;
  • Preparation of technical report with findings and recommendations.
  • Welding fumes that the employees are being exposed to mainly consist of gaseous components and particulate fumes with varying concentration and composition. The fume composition depends mainly on the type of the welding rod, welded material and the welding technique. Particular components of welding or cutting fumes can be toxic to humans and long term exposure to these fumes can result in deterioration in health resulting in conditions such as Pneumonia, Throat irritation, Metal fever, Occupational asthma and others.
