I think it kicks off cy*n!de, not nice, thats why they banned the foam ceiling tiles that everybody was fitting in the 1970's and early 1980's....and a lot of furniture foam which was present in old seats/chairs in Student halls in massive numbers that had been in them and not replaced since the late 1970's..they got rid of them from 2003 onwards...someone I know works in a plastics factory and the chemicals they use to make it are kept in several separate safes, in forced air vent/fan filled rooms, theres alarms and cameras and they have to count it in and count it out, sign for the amount used each day, and theres special licences they have to maintain to buy it, if they go through a lot a guy from the company that sells them it comes out and demands a meeting, and only about 3 people out of about 30 workers are allowed to handle it, and I think two of them can add/mix it in the production factory...anybody else even looks at it funny then the whole place would be shut down in a flash...
A few guys were helping themselves to scrap cuttings from work there to take home to use to light their household fires instead of firelighters and started giving carrier bags of it to their pals in the pub, then somebody said "eh is that not dangerous" and lifted the phone, when the owners of the company found out they went mental.....they are chemical engineers and knew what they put into the stuff to make it set...
