Background Occupational exposure to methylene bisphenyl isocyanate (MDI) presents serious worker health concerns as it may lead to short- and long-term health effects such as asthma, airway irritation, hypersensitivity pneumonitis, and irritation of skin and mucous membranes. While studies of worker isocyanate exposures during vehicle painting activities are widespread, few studies have investigated the spray-on truck bed-liner (STBL) industry. The purpose of this study was to determine the… Expand

Isocyanate Exposures in Autobody Shop Work: The SPRAY Study
Despite improvements in autobody shop materials, practices, and controls, there are still opportunities for substantial exposures to isocyanate, and the frequency, duration, and intensity of isOCyanate exposures are outlined. Expand
Measurements of Airborne Methylene Diphenyl Diisocyanate (MDI) Concentration in the U.S. Workplace
A large body of industry air sampling data in which airborne MDI concentrations were measured in a wide variety of manufacturing processes that use either polymeric MDI (PMDI) or monomeric (pure) MDI is summarized. Expand
Indirect assessment of 4,4'-diphenylmethane diisocyanate (MDI) exposure by evaluation of specific humoral immune responses to MDI conjugated to human serum albumin.
It is demonstrated that serum concentrations ofMDI-specific IgG appear to be a moderately sensitive biological marker of MDI exposure, but not an indicator of occupational asthma. Expand
Asthma death after spraying polyurethane truck bedliner.
The need for isocyanate manufacturers/formulators to inform end users of their products of appropriate health and safety work practices associated with new technologies demonstrates the need for health care providers to recognize and manage work-related asthma. Expand
MDI Exposure for Spray-On Truck Bed Lining.
It was concluded that workers in the urethane sprayed-on truck bed lining industry are at an increased risk of developing illnesses associated with isocyanate exposure. Expand
Comparison of Task-Based Exposure Metrics for an Epidemiologic Study of Isocyanate Inhalation Exposures Among Autobody Shop Workers
The task-based exposure modeling method successfully produced estimates of daily time-weighted average exposures in the complex and changing autobody shop work environment, and supports the reports of others that reducing exposure misclassification can improve risk estimates that otherwise would be biased toward the null.

Prevention Guidance for Isocyanate-Induced Asthma Using Occupational Surveillance Data
Key observations are made regarding the development of work-related asthma in association with a) paint application on large objects difficult to ventilate, b) indirect exposure to isocyanates, c) exposure during secondary or cleanup processes, and d) reports of dermal exposure. Expand
Surveillance of Washington OSHA Exposure Data to Identify Uncharacterized or Emerging Occupational Health Hazards
Observation of OSHA inspection data can be a valid tool to identify uncharacterized and emerging health hazards, and Federal OSHA and other state OSHA agencies will need to add electronic data entry fields more descriptive of industry, process, and substance to fully use agency exposure data for hazard surveillance.
