Requirement for Maintaining Clean Ductwork
Generally there is a duty of care that an employer should supply a minimum quantity of “clean and purified air” this forms the crux of the legislation that is set out in the “Health and safety at work act 1973” obviously this applies to the entire workspace, but where you have a specific clinical requirement then other codes of practice come into play. So simply put you cannot get clean air from a dirty duct!
Although duct work may be filtered, no filter is absolute, even HEPA filters will let by some particles, but more over when they are changed dirt can be transferred into the clean side of the system, also typically the ductwork was never cleaned from new, only recently have new installations been required to have a pre clean.
There are also efficiency issues with having dirty ductwork, the dirt will inevitably contaminateand block HEPA filters reducing their life expectancy, it can also increase the resistance of the system further reducing the a vailable volume of air that can be supplied and putting additional strain on the fan and motor.
