Hi,

The consensus seems to be that it will pose no risk as long as you don't drill, sand, demolish or otherwise disturb it.

If you click on the Search Forum link in the blue banner towards the top of this page and type in asbestos, you should find some useful information. Here's just one example www.cancerresearchuk.org/.../asbesto...

I've seen a few similar questions on here and the advice always seems to be that short term, low level, exposure to asbestos is highly unlikely to cause problems. 

Asbestos was in common use until the 1980s when it was banned in the UK (amazingly it still isn't banned in the USA) and the majority of people who were affected by it were exposed to it for long periods - months or years - rather than just the once. 

Try not to worry too much about this. 

Best wishes

Dave
