@25b5e014 yeah, never squeeze the corrugated pipe wrap.  But one of the stupidest things ever was the huge push to remove VAT from schools, because it was perfectly safe in place, especially if you put a new flooring or carpet over it.  But breaking it up to remove it created a massive increase in particulates, resulting in higher level of asbestos for YEARS afterward. 

 @1bd21f55 well if the asbestos doesn't get me I'm sure a lot of other chemicals I've inhaled in abandoned places will be happy to do it
