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
