I have a client with an appeal against refusal of IIB based on prescribed disease C23 -- cancer of epitheliean lining of the urinary tract from exposure to orthotoluidine, 4-chloro-2-methylaniline or or salts of those compounds. Client worked in the print industry for six years between 1952 and 1964 and was regularly explosed to ink and solvents includinding cleaining under machines etc. but has no knowledge of names of products.

DM accepted on balance of probability that she had been exposed to these chemicals, but this has been overturned on Medical Service advice. I can try various means of investigation, but don't want to re-invent the wheel, does anyone have: Knowledge of a 'lookalike' Commissioners decision or good sources of information on the chemicals likely to have been encountered in print works (since closed) 50 years ago?

Try contacting the one of the print unions. In the period during which your client worked in the industry they were closed shops, and she was almost certainly a union member. Most of the print unions merged into what is now Amicus http://www.amicustheunion.org/

We are following that up, unfortunately the full time officer responsible for the industry in bristol is on long-term sick leave, and although she is certain she was a chapel member she can't remember of which union! But I may well try contacting their health and safety section nationally and I have found some useful information on the GMB website.
