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.
