  • (Source: Health and Safety Executive). S = substantial (1–50%), T = Trace (less than 1%), or quantification not undertaken. Samples 43–48 were analysed by polarised light microscopy in 1994. Samples 126 to 136 were analysed by both polarised light microscopy andx ray diffraction in 1995. Glass fibre was identified in samples 127 and 129. Sample 133 was a charred sample in which asbestos could have been present before burning. Fosterite is a reaction product of chrysotile asbestos when heated in excess of 500°C. Samples 130 and 131 consisted of a loose collection of material too small to quantify by x ray diffraction.
