8. Exposure Controls / Personal Protection
space
Personal protective equipment
Eye protection Wear safety glasses with side shields.
space
Skin and body protection Use impervious gloves. Work clothing sufficient to prevent all skin contact should be worn,
such as coveralls and long sleeves.
space
Respiratory protection Avoid breathing vapor and/or mists. If airborne concentrations are above the applicable
exposure limits, use NIOSH approved respiratory protection. High airborne concentrations may
necessitate the use of self-contained breathing apparatus (SCBA) or a supplied air respirator.
space
General Eyewash fountains and emergency showers should be readily available.

10. Chemical Stability & Reactivity Information
space
Hazardous polymerization Hazardous polymerization can occur with elevated temperatures or contact with water.
space
Conditions to avoid Avoid Strong Acids. Avoid amines, strong bases, alcohols and metallic hydrides. Keep away
from sources of ignition.
space
Stability
This product is stable under normal conditions but will react slightly with water to release some
heat and carbon dioxide. The reaction is not violent. Carbon dioxide, carbon monoxide and in
high temperature (800° F) low oxygen atmospheres such as in fire situations, hydrogen
cyanide may be released.
