Indoor Air Quality

What are the current 'Indoor Air Quality' legislative standards?

There are several guidance notes to consider, and groups to pay attention to, within the indoor air quality industry. Our procedures and standards are taken from recommendations from the HSE (Health and Safety Executive), the Expert Panel on Air Quality Standards (EPAQS has been merged into the Department of Health's Committee on the Medical Effects of Air Pollutants [COMEAP]) and The World Health Organization (WHO) guidance.

In addition, there is a need to observe the following guides and aims:

  • UK National Air Quality objectives
  • UK air quality bands
  • European Community Directives Limit and Guide Values
  • United Nations Economic Commission for Europe critical levels

Employers' Responsibilities
The Health and Safety Executive recommends that employers and building owners take the steps outlined below to combat the risk of Sick Building Syndrome:

  • Survey your staff – Take a detailed look at sick-days, symptoms and general air quality or environmental complaints.
  • Check the general cleanliness of the building, looking for dust and debris - including checking vacuum cleaners filtration.
  • Check that cleaning materials, chemicals or other products that may be of an aerosol nature, are used and stored well.
  • Check the heating system, ventilation and air-conditioning in the building. Acute attention to be paid to fresh air circulation.
  • Make sure air filters, humidifiers, de-humidifiers and cooling towers are clean (See your towers' legionella risk assessment).
  • Check any plan, according to the above noted systems (heating, humidifiers etc.) that may detail maintenance and cleaning checks – these are very important. If you have no plan for these, one should be devised

After taking precautions such as these, if sick building syndrome symptoms persist, it will be necessary to carry out a more detailed investigation of the workplace. To help you with this we can carry out the investigation and devise the plan you need to keep your staff healthy.
