Exposure Guidelines
No exposure limits have been established for this material. It is recommended that
exposure be kept below the limits for particulates not otherwise classified. OSHA-PEL:
15 mg/M3 8 hr-TWA (total dust) 5 mg/M3 8 hr-TWA (respirable) The American
Conference of Governmental Industrial Hygienist (ACGIH) has established a Threshold
Limit Value (TLV) (based on an 8-HR TWA exposure) of 1 mg/m3 for the respirable
fraction. This TLV applies only to the polymerized form of vinyl chloride and not the
vinyl chloride monomer.
The following materials may be present in this product when processed during extreme
temperatures that are beyond normal operating temperatures, but are not anticipated to
exceed exposure limits under normal processing conditions:
Component
OSHA - PEL
ACGIH-TLV
Hydrogen Chloride (HCl)
5ppm ceiling
2ppm ceiling
Calcium Carbonate
15mg/m3 8 hr TWA
(total dust)
5mg/m3 hr TWA
(respirable)
10mg/m3 8hr TWA
Again, these hazardous components may be released during extreme process
temperatures. These components are dependent on processing conditions and should be
verified by the 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 15-minute period.
