In past issues of the Report we have discussed the dangers associated with workplace exposure to isocyanate chemicals in spray polyurethane foam (SPF) insulation. Spray application of SPF insulation generates isocyanate vapors and aerosols that can migrate throughout the building if it is not isolated and properly ventilated. Both inhalation and skin exposures can lead to the worker suffering serious health effects.
