Hygiene Contracts provides complete duct cleaning services throughout the UK,, Europe and the World in accordance with the requirements of TR/19, the leading guidance document issued by the B&ES Association; British Standard and European Norm BSEN:15780; and BG49/2013, BSRIA’s guide on Commissioning Air Systems. All three sets of guidance now agree on the way to ensure appropriately clean ductwork both at commissioning stage and during service to ensure safer and healthier buildings.
To be compliant with TR/19, ventilation supply and extract ductwork must be classified at one of three levels, according to the area of the building that it serves. Each system must be classified as high, medium or low, in order to reflect the purpose and function of that area of the property. This means that there can be different classifications for individual zones within the same building or complex.
You may need expert help and guide you to determine which category or categories your ventilation systems fall into and how often the ductwork should be tested and cleaned as a result, according to the tables set out in TR/19. Hygiene Contracts can advise on system access design and installation and specialises in devising tailored hygiene maintenance schedules to ensure that you achieve compliance with TR/19, and stay compliant in the most cost effective way in each property for which you are the appointed responsible person.
Dirty air ducts and ventilation systems can affect your business in a variety of costly ways, these can include; a drop in productivity, low employee morale, computer downtime, ruined interior decorations and high capital expenditure to replace prematurely deteriorated air conditioning systems.
What is even more of a concern is the very real threat to building managers of prosecution, should ducts not comply with the regulations of the Health and Safety Commission, which state that ventilation systems should be cleaned, as appropriate and subject to ‘a suitable’ system of maintenance. The level of appropriateness is defined clearly in TR/19 second edition and also BS EN 15780 and depends on the usage classification of the building in question.
It is important to note that a ventilation system, through which the air that we breathe passes, typically has an internal surface area equivalent to 10% of the space that it serves. This puts into context the importance that should be placed on appropriately managing the hygiene within any ventilation system.
To ensure compliance with the Regulations and associated Approved Code of Practice from the Health and Safety Commission which states that all mechanical ventilation 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.
