Isocyanates are the most common cause of occupational asthma at the moment. They are present in 2-pack paints (where they are a problem during mixing, painting and curing), glues, foams, rubbers, pesticides and dyes. They can also be a problem for welders, solderers, assemblers, moulders, core makers, printers, and anyone who is working in an environment where Isocyanates are used.
The Oasys Audit scheme started midway through 2010 and collects agents typed in through the Oasys program. The years before 2010 show old data entered during 2010 or later and are likely to have many fewer notifications. We expect Oasys to become more widely adopted as time goes by so increasing notifications does not necessarily mean an increasing problem.
