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

CAUTION
To prevent cross-contamination of the gun's wetted
parts, do not interchange A component (isocyanate)
and B component (resin) parts. The gun is shipped
with the A side on the left. The fluid manifold, fluid
housing, side seal cartridge, check valve cartridge,
and mix chamber are marked on the A side.
