Asbestos in it's solid form is actually pretty harmless, and it has a huge amount of benefits. The downside is the particulates say in the air for days or weeks, and they cause horrific cancers.
Its really hard and expensive to get rid of asbestos safely, but it's pretty inert after it's actually installed somewhere.
Ah you're right. I misread your comment. I thought you were calling gas a liquid haha
