New measurement methods make it possible to study the decomposition products of polyurethanes. Other constituents of technical isocyanate products can also be determined. New measuring instruments providing direct readouts have been developed and this has made it possible to trace isocyanate levels over a period of time and also to register short processes, thus enabling us to identify critical manufacturing operations. New methods for analysing urine and blood samples have also been developed. The following are some of the symptoms that can arise.
