Environmental monitoring

Occupational air quality measurements

Ensuring air quality is within allowed limits

Accurate monitoring of indoor air quality is important to ensure human exposure to harmful substances does not exceed regulatory limits. An NPL survey monitors and assesses indoor air quality to provide an accurate account of the levels of gas present in the work place. Routine surveys enable:

  • Assessment and quantification of indoor air quality
  • Identification of air quality zones and areas of exceedance
  • Odour investigations

NPL's experienced staff can design monitoring campaigns and provide expertise and advice to occupational hygienists on the gas species exceeding environmental health regulations.
