For example if the door was manufactured in the 60 s and has a white core how can you tell whether it s a mineral core or asbestos or something else. Presume that the door contains asbestos see below for instructions for.

Sadly exposure to asbestos was possible any time the interior mineral cores of these fire doors were disturbed in some way. Up to the early 1980 s fire doors were manufactured from asbestos boards fibre cement boards or mineral fibre cores. Every ceasefire fire door set strictly conforms with as1905 part 1 2005. When asbestos was banned in fire doors there was thousands of fire doors still in warehouses around the country that eventually sold were install into the 90 s.
