Indoor Air Quality

Professional Indoor AirTesting

With indoor air testing, the kinds of air contaminants within the premises are identified. It is also determined whether the amount of these contaminants is still within acceptable levels.

The results of testing are compared against the workplace and occupational exposure limits set by regulation. Finally, a list of recommended actionable items is handed to the employer.

The following factors are measured during testing:

  • Airborne Bacterial Analysis
  • Airborne Fungal Analysis
  • Carbon Dioxide (CO2)
  • Carbon Monoxide (CO)
  • Relative Humidity (%)
  • Temperature (oC)

indoor-air-testingWith the help of testing, we determine whether the concentration of the contaminants present in the air exceeds the maximum allowable concentration based on potential adverse effects on human health. We look for contaminants like gases, microorganisms, vapours, dust, smoke and other particulate matter.

These contaminants are either already present in the make-up air indoors or they have been introduced through several agents like building materials, furnishings, surface coatings, indoor activities, air treatment or air handling components.

During indoor air testing, we also look into the following factors – potential to induce infections or allergies, irritants, toxicity, objectionable odours and thermal conditions.

Although the main priority of testing is to ensure a safe and comfortable air quality for occupants, it is also done to follow regulation. Our indoor air quality assessment services ensure adherence to the following:

  • The Chartered Institution of Building Services Engineers (CIBSE)
  • the Health & Safety Executive (HSE EH 40/02 Occupational Exposure Limits & HSE EH 40/05 Workplace Exposure Limits)
  • the Building Services Research and Information Association (BSRIA) and the Workplace (Health, Safety & Welfare) Regulations 1992.

If necessary, we can also include additional parameters in our testing upon request. While conducting our assessment, we can also test for Ozone (unstable Oxygen, O3), Nitrogen Oxide (NOx), Volatile Organic Compounds (VOC’s) and Total Dust Particulates.
