Where conditions exist in a building for surfaces to remain damp or wet, mould, fungi and bacteria can develop and present a health risk for occupants.
The role of non-infectious microorganisms in indoor environment related diseases is currently poorly understood. The World Health Organisation (WHO) publication Assessment of Health Risks to Biological Agents in the Indoor Environment – 2009, Guidelines for Indoor Air Quality, Dampness and Mould cites that:
"As the relationship between dampness, microbial growth and health effects cannot be quantified precisely, no health-based guideline values or thresholds can be recommended for acceptable levels of contamination by microorganisms. Instead, it is recommended that dampness and mould-related problems be prevented. When they occur, they should be remediated because they increase risk of hazardous exposure to microbes and chemicals."
Exposure to airborne mould spores can affect individuals differently, with the very young, elderly or those with already compromised immune systems likely to be more susceptible.
Mould & Damp Surveys
BENSS provides commercial and residential surveys for damp and mould growth, including air testing for associated spores and micro-organisms using specialised monitoring equipment.
In many cases there may be multiple sources of damp, or issues with drainage or ventilation causing damp to remain for extended periods. Even if surfaces are not noticeably damp or mould affected, airborne contaminants may already be present.
Using infrared imaging our experienced mould consultants are able to survey buildings for damp before it is noticeable or presenting a health risk. Infrared imaging uses small differences in temperature between surfaces to produce a picture of heat and is proving to be an effective pro-active maintenance tool for a broad range of building and equipment issues.
