This study, written by Carrie Riedlich in June 2010, focuses on identifying and collecting data on PU products that are commonly used and most likely to present skin exposure risk to applicators or others in the work area.
Isocyanates are used to make polyurethane, a synthetic material that has many commercial and industrial uses.The Standards and Technical Resources Section of Oregon OSHA produced this fact sheet to highlight our programs, policies, or standards. The information is from the field staff, research by the technical resources staff, and published materials.
4,4’-Diphenylmethane diisocyanate (MDI) Safety practices and Concentration During Polyurethane Foam Spraying (PDF)http://www.irsst.qc.ca/files/documents/PubIRSST/R-629.pdf
The scope of this study was to document hazardous practices and to evaluate the work environment in terms of MDI concentrations (monomer and oligomers), in stationary sampling, during spraying work (aerosols and vapours) and post-spraying (vapours) on Québec construction sites based on the work being carried out.
This National Library of Medicine source provides information on isocyanates related to sources, adverse effects and links to other toxicology and medical databases.
Isocyanates are widely used in the manufacture of flexible and rigid foams, fibers, coatings such as paints and varnishes, and elastomers, and are increasingly used in the automobile industry, autobody repair, and building insulation materials. This page provides access to NIOSH reports and information addressing isocyanates.
Isocyanates are compounds containing the isocyanate group (-NCO). They react with compounds containing alcohol (hydroxyl) groups to produce polyurethane polymers, which are components of polyurethane foams, thermoplastic elastomers, spandex fibers, and polyurethane paints. This topic page addresses applicable OSHA standards, examples of hazards and possible solutions, sources of information on sampling and analysis and more.
