Occupational asthma from isocyanates

I would like to know whether or not you have come across any cases of occupational asthma from exposure to isocyanates during the use of bonding materials/adhesives, applied as a paste or bead, not sprayed. The process I’m talking about is the installation of glass or windows or cutting and gluing of screens, on a tramcar or coach bodies, buses etc. Many thanks in advance.

I have had several cases of occupational asthma in windscreen installers, both in primary production and the fixing of replacement glass. The levels of (usually MDI) are very low as measured, but the paste is usually heated. I have seen one worker on a car production line working underneath a window subassembly area who developed occupational asthma, so the exposures may be indirect. The Shield database (our database containing details of occupational asthma referrals in the West Midlands) has 6 patients who are windscreen fitters and are thought to have problems with the isocyanates in the glue, we also have 2 bus builders thought to have problems with isocyanates (which could possibly be from glue, but it is not specified unfortunately), and we have 8 patients who are gluers of some sort with occupational asthma.
