Do I need air testing after installing new machinery?

Yes — in many cases, you should carry out air testing after installing new machinery, especially if it could affect air quality or employee exposure to harmful substances.

You Need Air Testing If the New Machinery:

• Produces dust, fumes, vapours, or gases
  (e.g., welding equipment, grinders, spray booths, ovens)
• Uses hazardous substances
  (e.g., solvents, resins, cutting fluids)
• Generates heat, increasing the risk of poor ventilation or indoor comfort issues
• Alters airflow or ventilation, especially if it's large or enclosed
• Changes how workers are exposed, e.g. moves a hazard closer to people or affects existing controls like LEV
