Spraying or dispensing uids that contain isocyanates creates potentially harmful mists, vapors, and
atomized particulates.
• Read and understand the uid manufacturer’s warnings and Safety Data Sheet (SDS) to know specic
hazards and precautions related to isocyanates.
• Use of isocyanates involves potentially hazardous procedures. Do not spray with this equipment unless
you are trained, qualied, and have read and understood the information in this manual and in the uid
manufacturer’s application instructions and SDS.
• 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 tting respirator, which may include
a supplied-air respirator. Ventilate the work area according to instructions in the uid manufacturer’s SDS.
• 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 uid manufacturer and local
regulatory authority. Follow all uid 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 specied by the uid 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
