Product identification

As most of older type of fire doors dont have any labels or distinct markings it is very hard to positively identify asbestos content. The only way to do it is by sampling, but this is a destructive process and hygienists prefer to classify them as: suspected positive or suspected negative, based on their age and appearance. Newer types of fire doors are labelled, which make it easier to identify them as asbestos-free.


Friable asbestos had been positively identified as thecore-insulation material in some substation fire doors such as switch roomfire doors (wooden clad) in the form of core insulation, transformer roomentrance doors (steel clad) in the form of mastic insulation, interior entranceand connecting fire doors (wooden clad) in the form of core insulation.
