OSHA IMIS Code Number: V109
Chemical Abstracts Service (CAS) Registry Number: 8032-32-4
NIOSH, Registry of Toxic Effects (RTECS) Identification Number: OI6180000
Department of Transportation Regulation Number (49 CFR 172.101) and Guide: 1268 128 (petroleum distillates, n.o.s.)

Exposure Limits
American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 300 ppm, 1370 mg/m3 TWA; Appendix A3 - Confirmed Animal Carcinogen with Unknown Relevance to Humans
National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 350 mg/m3 TWA; 1800 mg/m3 Ceiling (15 Minutes)
Health Factors
Potential symptoms: Irritation of eyes, upper respiratory system; dermatitis; CNS depression; chemical pneumonitis (from aspiration of liquid).
Health Effects: Irritation – Eye, Nose, Throat, Skin---Mild (HE16); Narcosis (HE 8); Explosive, Flammable (HE18)
Affected organs: Eyes, skin, respiratory system, CNS
Notes:
- OSHA does not have a PEL for VM & P naphtha.
- Of seven human volunteers exposed to 880 ppm for 15 minutes, four experienced irritation of the upper respiratory system, three had eye irritation, and six had “olfactory fatigue.” None of these effects persisted one hour after exposure.
