The results came back from the lab. It is “chrysotile”, with asbestos in! It appears from what I have read, this is the least dangerous and was not disturbed since I have been there, I am now going to move out pronto. Luckily I was not in the workshop a lot, just using it for storage and the odd car repair, but some people are in these units all day, and have removed boards etc
I am also considering going to get some legal advice…
I learnt a lot here, mainly that you can’t tell by looking at a material whether it contains asbestos. Even people who appear knowledgeable are not, just as Tymbian says it needs lab testing. Secondly, I learnt that Landlords may appear to know what they are doing but may be in a position of ignorance as well.
