Mould and Health

There is a growing awareness of the need to keep homes dry and warm, not only to provide a comfortable environment, but to prevent the growth of mould. Mould spores are carried by air and are found everywhere. When conditions are right they will germinate and start to grow. There are thousands of different types of mould, some of which are harmless, some can be beneficial and some are potential health hazards. When dealing with leaking buildings the potential for finding mould in wall cavities is very high. It is important that the proper precautions are taken to ensure that neither workers nor building occupants are exposed to health hazards from moulds during building repairs.

The New Zealand Department of Labour, Occupational Safety and Health Bulletin No. 17 "Risks to Health From Moulds and Other Fungi" provides more information on moulds and their possible effects on health.
