Isocyanate Hazard

Isocyanate Hazard

Spraying materials containing isocyanates creates potentially harmful mists, vapors, and atomized par- ticulates.

Read material manufacturer’s warnings and material MSDS to know specific hazards and precautions related to isocyanates.

Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventila- tion in the work area. If sufficient ventilation is not available, a supplied-air respirator is required for everyone in the work area.

To prevent contact with isocyanates, appropriate per- sonal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

Keep A and B

Components

Separate

CAUTION
