8. EXPOSURE CONTROLS/PERSONAL PROTECTION
(Continued)
Additional hazardous constituents may be released during processes involving elevated temperatures. These constituents
are dependent on processing conditions and should be verified by processor.
Under normal processing conditions, no occupational exposures to vinyl chloride monomer exceeding the established
exposure limits for this material are anticipated. The OSHA-PEL for vinyl chloride is 1 ppm over an 8-hr TWA. The OSHA-
STEL for vinyl chloride is 5 ppm for any 15minute period.
Local and state regulations regarding the handling and storage of chemicals may vary widely. The user should acquire
knowledge of these and other appropriate federal and state laws and regulations as well as consult with the proper authority
for guidance in developing adequate handling procedures and constructing appropriate storage facilities.

Hazardous polymerization will not occur.
Hazardous Decomposition Products
Overheating may cause thermal degradation of PVC compound. Fumes and vapors (including CO, CO

, and HCl) may be
generated during this thermal degradation. Emissions are also possible during normal operating conditions, and may
accumulate within an inadequately ventilated facility.
