Air Monitoring & Cleanliness of Ventilation System

‘The internal cleanliness of ventilation systems is considered important for human comfort and health, energy consumption, system service life and for cleanliness of operations or processes carried out in the ventilated area.’ – INTERNAL CLEANLINESS OF VENTILATION SYSTEMS (TR19)

Ventilation systems by their very nature will accumulate contamination to a degree which will be influenced by the quality of the incoming air, filtration, design, maintenance and usage. Over time varying types of contamination will accumulate to levels which may detrimentally influence the quality of the supplied air and hence may affect the health of building users. Contaminant levels can build to such an extent that they provide the added risk of fire propagation.

An average adult at rest inhales approximately 11,000 litres of air (388 cubic feet) in a day. The quality of the air we breathe can have significant implications to our health and quality of life.

Under the Management of Health & Safety at Work Regulations 1999 it is the duty of every employer to make a suitable and sufficient assessment of:

  • The risks to the health and safety of his employees to which they are exposed whilst they are at work, and
  • The risks to the health and safety of persons not in his employment arising out of or in connection with the conduct by him of his undertaking.

Regulation 5 of the Workplace (Health, Safety and Welfare) Regulations 1992 imposes a duty to clean mechanical ventilation systems “as appropriate”. Regulation 6 states, “effective and suitable provision shall be made to ensure that every enclosed workplace is ventilated by a sufficient quantity of fresh or purified air”

ACOP6 (52) relating to Regulation 6 of the Workplace (Health, Safety and Welfare) Regulations, 1992 states that “mechanical ventilation systems (including air conditioning systems) should be regularly and properly cleaned, tested and maintained to ensure that they are kept clean and free from anything which may contaminate the air”.
