Posted By andy tetlow hi, im wondering what the legislation or acop is for the safe removal of ceramic fibre insulation at high temps. is it the same as asbestos regs? eg.air locks, full enclosures and respiratory equipment. also what is classed as 'high temperature.' cheers

Posted By Mitch Have you tried ID 267/3?

Posted By Stephen J Barnes Firstly does the RCF material need to be removed at high temperatures? If removal at high temperatures cannot be avoided then a thermal comfort risk assessment will be required. See http://www.hse.gov.uk/te...rature/thermal/index.htm The HSE Information document HSE 267/3 provides useful guidance, however it is little dated (1998). You might be aware that RCF now has a separate WEL of 5 mg/m3 and 1 fibre/millilitre (8-hour TWA). The HSE Information document 267/3 refers to the MMMF MELs of 5 mg/m3 and 2 fibres/millilitre (8-hour TWA). The MMMF exposure limits remain but are now referred to as WELs. For current definitions of RCF and MMMF see http://www.hse.gov.uk/coshh/table1sup.pdf . Exposure to respirable crystalline silica may also be an issue. Note that Respirable crystalline silica has a WEL of 0.1 mg/m3 (8-hour TWA). For more details see the revised EH40 (October 2007) at http://www.hse.gov.uk/coshh/table1.pdf I hope that this is useful. Should you require any assistance with thermal comfort assessment or personal exposure monitoring please contact me off forum at info@oakenvsol.com
