Chrysotile is white asbestos, the serpentine mineral that accounts for the overwhelming majority of asbestos used in Britain. It is in cement sheeting, textured coatings, floor tiles, gaskets, rope seals and mouldings. It was the last type banned here, in 1999, which is why buildings from the 1990s can still hold it. Removal rules do not follow the mineral: they follow the material and the work.
What chrysotile is in
Almost everything low content and bound: asbestos cement roof and wall sheeting, rainwater goods, water tanks, flue pipes, textured decorative coatings, vinyl and thermoplastic floor tiles, gaskets and rope seals, and some plasters and mouldings. It also appears alongside amosite in insulating board, and in some insulation products with the other types.
Why the type does not decide the rules
Licensing follows the material and the work. Sprayed coatings, thermal insulation and most work on insulating board are licensable whichever mineral they contain. Asbestos cement and textured coatings are normally non-licensed whichever mineral they contain. A chrysotile certificate is a useful fact for the register and it is not a permission slip.
What the analysis certificate tells you
The mineral or minerals identified in that sample. That goes on the register beside the material, the location and the condition, and it can matter when a contractor is planning controls or when a historic exposure question arises. It does not make a material safe and it does not change who may remove it.
Chrysotile removal, material by material
Exactly as for the material it is in. Cement sheeting comes down whole and is consigned as hazardous waste. Textured coating comes off wet or with a softener. Insulating board is a licensed job with an enclosure and a clearance. The mineral name changes nothing about any of that, which is why a quote framed around the type rather than the material is worth questioning.
Questions people ask about chrysotile asbestos removal
Is white asbestos safer to remove?
The regulations treat all types under the same regime, and the controls follow the material and the work. This site does not make comparative health claims about the types.
Was chrysotile banned later than the others?
Yes. Amosite and crocidolite were prohibited in 1985 and chrysotile in 1999, which is why later buildings can still contain it.
Does the certificate always name the type?
An analysis that identifies asbestos names the type or types found. A result of none detected names nothing, because there was nothing to name.
How is asbestos roof tiles removal handled?
By the material rather than by the fibre type: cement based tiles taken down whole are usually non licensed, while an insulating board or a sprayed coating is not. The analysis names the type and the material decides the rules.
