Title Airway symptoms and lung function in pipelayers exposed to thermal degradation products from MDI-based polyurethane
Bibliographic information Dec. 1997, Vol.54, No.12, p.873-879. 22 ref.
Abstract The prevalence of episodes of irritative eye symptoms, congestion of the nose and soreness or dryness in the throat was much higher among a group of pipelayers exposed to polyurethane (PUR) containing methylene diphenyl diisocyanate (MDI) than among unexposed controls. Most of the pipelayers with symptoms reported that these had started and occurred in relation to PUR welding tasks. Pipelayers with recent high PUR exposure showed a significant reduction of forced expiratory volume in one second compared with controls. Exposure to thermal degradation products from MDI-based polyurethane has adverse effects on the mucous membranes and airways. Topics: diphenylmethane diisocyanate; polyurethane; epidemiologic study; irritation; one-second forced expiratory volume; pipelaying; pulmonary function; pyrolysis products; respiratory diseases; smoking; welding and cutting.
