Air duct

Legislation and Guidance

The workplace, and the equipment and devices mentioned in these Regulations, should be maintained in an efficient state, in efficient working order and in good repair.

Regulation 5

Mechanical ventilation systems shall be maintained (including cleaned as appropriate) in an efficient state, in efficient working order and in good repair.

Regulation 6

Mechanical ventilation systems (including air-conditioning systems) should be regularly and adequately cleaned. They should also be properly tested and maintained to ensure that they are kept clean and free from anything which may contaminate the air.

Condition monitoring takes the surprise out of ventilation clean requirements and helps avoid expensive call out/shut down cleans.

Air Duct Cleaning

Legislation and Guidance

This European Standard applies to both new and existing ventilation and air conditioning systems and specifies the assessment criteria of cleanliness, cleaning procedures of these systems, and the validation of the effectiveness of cleaning applies also to products, which conform to EN 1505,EN 1506, EN 13053, EN 13180 and EN 13403, used in air conditioning and ventilation systems for human occupancy defined in the scope of CEN/TC 156.

This European Standard does not apply to installations for industrial processes. 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. Considerations for change of component as an alternative for cleaning (e.g. in case of flexible ducts and air filters) are also included.

Legislation

The Health and Safety at Work etc Act 1974, lays down that:

Section 2 (2) (e)

“Requires that you as an employer , provide and maintain a working environment that is, so far as is reasonably practicable, safe and without risk to health.”

Legislation and Guidance

The Department of Health Technical Memorandum 03-01: Specialised ventilation for healthcare premises Part B : Operational management and performance verification  has introduced new practices for the management of healthcare ventilation systems.

Findings should be recorded and areas with visible dirt or deposits should be cleaned.
