Ventilation Systems Hygiene and Assessment

Indoor air quality can impact the health, comfort and productivity of building occupants. Contaminated air can lead to Sick Building Syndrome; tiredness, lethargy, headaches, dry or itchy skin and eye irritation in employees. Those with asthma or patients in healthcare facilities are particularly vulnerable.

When is a ventilation condition report needed?

The Workplace (Health, Safety and Welfare) Regulations 1992, regulation 5, requires that mechanical ventilation systems are regularly maintained (including cleaned as appropriate) to keep them free from anything which may contaminate the air and cause health problems. There are two clear instances when a ventilation condition report and cleaning service may be required:

i. When a new ventilation system has been installed.

It is important to sanitise it before first use, to prevent contamination from the inevitable dust and other pollutants arising from building works. We issue a certificate of hygiene to confirm the system is safe for use.

ii. When a system has been in use for a lengthy period.

In some cases the naked eye can see mould and thick dust – but we also take swab tests to analyse the level of dust and bacterial deposits present. We interpret the lab microbiology results and advise if a clean is required.

We ensure that your ventilation system is clean or sanitised to the legal standards giving you peace of mind that the air being pumped into your facility is pure.
