G'day Sandra,I think Mudcat might have got picky last night (Aust. time) ... I had to reset my cookie as well.
Anyway: The Asbestos Removal text on my desk says:
"crocidolite (blue asbestos)
Crocidolite is considered to be the most dangerous type of asbestos ... although all types are treated as being equally hazardous."
