The company standard for COSHH where I work defines a carcinogen as a substance which causes cancer. However some of the MHDS for our materials use the terms category 1, category 2 & category 3 carcinogen. COSHH regs 2002 don't make any distinction. So what's the difference?
Note: All 3 categories receive the most stringent level of control available, so this is purely to further my understanding of the terminology

Thanks, Chris

COSHH regulations do define "carcinogen "-

(a) a substance or preparation which if classified in accordance with the
classification provided for by regulation 4 of the CHIP Regulations would
be in the category of danger, carcinogenic (category 1) or carcinogenic
(category 2) whether or not the substance or preparation would be
required to be classified under those Regulations; or

(b) a substance or preparation -
(i) listed in Schedule 1, or
(ii) arising from a process specified in Schedule 1 which is a substance
hazardous to health;

Please refer to The COSHH ACOP/Guidance (L 5).Appendix 1 covers the Control of carcinogenic substances
