Air Monitoring

The Control of Substances Hazardous to Health Regulations (COSHH) require that you carry out air-monitoring where employees may be exposed to hazardous substances by inhalation, if those substances have a Workplace Exposure Limit (WEL). These substances are listed in the HSE’s EH40 document. There are many substances listed and ParaChem offers a service to measure all substances that can be sampled, such as;

  • Acid mists
  • Volatile Organic
  • Compounds (VOC)
  • Dusts
  • Metal Working Fluid (MWF)
  • Aerosols Isocyanates
  • Solder-flux fume
  • Ammonia
  • Phthalates
  • Metal dusts
  • Welding Fume
  • Asphyxiants
  • Chromium compounds
  • Diesel Engine Exhaust Emissions (DEEEs)
  • Oil Mist
  • Chlorine Organic acids
  • Formaldehyde
  • Cyanides
  • Very small particulate matter (respirable and thoracic fractions)
  • Triglycidylisocyanurate (TGIC)
  • Wood dust
  • Flour dust

Air-monitoring is also required under the Dangerous Substances and Explosives Atmospheres Regulations (DSEAR). The purpose of this monitoring is to determine the concentration of flammable substances in a zone and compare the concentrations to the Lower Explosive Limit (LEL). The LEL is the minimum concentration required to present a flammable atmosphere. Many commonly used chemicals can form flammable atmospheres and ParaChem can measure all commonly encountered substances, such as;

  • Acetone
  • Ammonia
  • Butane / propane
  • HFCs
  • Ethanol
  • Petroleum
  • Hydrogen
  • Glycol ethers
  • MEK (Butanone)
  • Styrene
  • Toluene
  • Xylene
