Spraying or dispensing fluids that contain isocyanates creates potentially harmful mists, vapors,
and atomized particulates.
• Read and understand the fluid manufacturer’s warnings and Safety Data Sheets (SDSs) to know
specific hazards and precautions related to isocyanates.
• Use of isocyanates involves potentially hazardous procedures. Do not spray with this
equipment unless you are trained, qualified, and have read and understood the information in
this manual and in the fluid manufacturer’s application instructions and SDSs.
• Use of incorrectly maintained or mis-adjusted equipment may result in improperly cured
material, which could cause off gassing and offensive odors. Equipment must be carefully
maintained and adjusted according to instructions in the manual.
• To prevent inhalation of isocyanate mists, vapors and atomized particulates, everyone in
the work area must wear appropriate respiratory protection. Always wear a properly fitting
respirator, which may include a supplied-air respirator. Ventilate the work area according to
instructions in the fluid manufacturer’s SDSs.
• Avoid all skin contact with isocyanates. Everyone in the work area must wear chemically
impermeable gloves, protective clothing and foot coverings as recommended by the fluid
manufacturer and local regulatory authority. Follow all fluid manufacturer recommendations,
including those regarding handling of contaminated clothing. After spraying, wash hands
and face before eating or drinking.
• Hazard from exposure to isocyanates continues after spraying. Anyone without appropriate
personal protective equipment must stay out of the work area during application and after
application for the time period specified by the fluid manufacturer. Generally this time period
is at least 24 hours.
• Warn others who may enter work area of hazard from exposure to isocyanates. Follow the
recommendations of the fluid manufacturer and local regulatory authority. Posting a placard
such as the following outside the work area is recommended:
