Indoor Air Quality

Legionella Risk Assessment Bromley and Croydon


Indoor air quality in the workplace can be affected not only by external air conditions but also by pollutants created in the workplace itself. Poorly maintained air conditioning and ventilation systems can harbor micro-organisms and respirable particulates and deliver contaminated air to all areas within a building. Dust mite allergens, pollen, fungal spores and micro-organsisms are just a few of the invisible sources that produce ill health in people working in a building. Furthermore, specific levels of some gases such as carbon dioxide, formaldehyde and the buildings ambient temperature and relative humidity also play a key role in maintaining indoor air quality.


The law recognises the importance of air quality through the Health and Safety at Work etc Act 1974, The Control of Substances Hazardous to Health Regulations (COSHH) and The Workplace (Health, Safety and Welfare) Regulations 1992. These regulations lay a clear duty on employers to measure, monitor and manage workplace air quality. In particular "Mechanical ventilation systems (including air conditioning systems) should be regularly and properly cleaned, tested and maintained to ensure that they are kept clean and free from anything that can contaminate the air."


Kitchen extraction systems within buildings become contaminated very quickly due to there frequent use. The build up of hot oils and fats within the extract ductwork can present a serious fire risk if steps are not taken to remove all flammable substances. In fact, if your kitchen extract system caught fire and you were unable to provide a certificate to prove it was cleaned recently your insurance liability may be affected. Amphibia provide a certified deep clean service to ensure flammable contaminants and fire risks are controlled.

The air handling units (AHU) and ductwork air distribution systems supply and extract air to/from spaces throughout your building. In doing so, these systems control quality of breathing air to protect personnel and sensitive equipment from potentially hazardous airborne contaminants. If contaminated, these systems can lose efficiency, fail to supply safe air, cause malfunction and even cause fire hazards.
