Important Isocyanate (ISO) Information

Isocyanates (ISO) are catalysts used in two component materials.

Isocyanate Conditions

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:
