Asbestos in boilers... Asbestos was commonly used in boilers until it was banned from use in boiler manufacture in 1984. Several pre-1984 boiler models are long-lived enough for examples still to be in use. The problem with these boilers is friable asbestos seals (on combustion camber covers for example). These seals are fragile and disintegrate when disturbed, shedding asbestos fibres into the atmosphere, presenting in my opinion a serious health risk to any technician working on that boiler. I maintain a short but growing list of boilers that I know from experience contain such seals, and I decline to work on these due to asbestos health risk. These models are all at least 25 years old and I advise prompt replacement if you own one because keeping it maintained is likely to be ever more difficult as fewer and fewer gas technicians are to work on them Here is my current list: Potterton Kingfisher MkI There are probably other boilers containing friable asbestos seals that
need to be disturbed during service/repair, and I'll add them to this list as I
encounter them.
Update 28th June 2011: I've just been sent a link to a very comprehensive list of appliances believed to contain asbestos. It's here. My list above turns out to be woefully inadequate!
In addition, if you are worried about the possibility of asbestos is your home, there are a number of companies who will advise you. Most will analyse a sample you send them to determine whether it is (or contains) asbestos, or visit you and carry out an asbestos survey. One such company local to me is www.avasbestos.co.uk (This is not a positive recommendation from me as I have no experience of them. It is a link to their site given to me by one of my own customers who was very happy with their asbestos identification service.)
