[Occupational exposure of workers to vapors of p,p'-diphenylmethane diisocyanate used in the production of building materials filled with polyurethane foam].

The building elements filled with polyurethane foam produced in Poland are called "Obornicka plate". The authors investigated the concentrations of p, p-diisocyanodiphenylmethane (MDI) vapours at workplaces and found considerably excessed TLV values. This would call for a prompt introduction of technological prophylaxis in the production of "Obornicka plate".
