Can trigger asthma, eye, throat and skin irritation. Avoid Carbon Monoxide problems from propane heaters, forklifts, and truck exhaust. Reduce carbon monoxide emissions through frequent equipment maintenance, and ventilation. All two-part epoxy paints and sealants should be suspected of containing isocyanates. Review MSDS for determination.
Isocyanates require extra precautions for workers and occupants.
Substitute a non-isocyanate product if possible. Do not apply isocyanate products while any area of the building is occupied. Confirm there is adequate ventilation and proper respiratory protection for workers in work area. Seal HVAC supply and return ventilation ducts inside construction area to prevent vapor migration to other areas. Seal rooftop air intakes for all building areas during roof work.
