Pollution control - air handling units
Air handling units
Many large factories, shops and office blocks have cooling towers associated with their air conditioning units. As there is a risk of spreading legionnaires disease from these units, legally, they must be registered with the local authority.
Air handling units within buildings may be linked to air conditioning systems. Many modern systems are " dry" and pose an insignificant risk. However some air conditioning systems are "wet", i.e. they use a water evaporative cooling system and can pose potential health risks if not properly maintained.
Any person responsible for, or business utilising a water cooled system, must carry out a thorough risk assessment in relation to it and must, by law, put in place all necessary procedures, including maintenance, to ensure that it does not pose a risk to public health.
These units may also contribute towards air pollution in the form of fumes and odour or noise pollution.
For complaints about noise, fumes or odour please email: scientificservices@barnet.gov.uk or
