Petroleum, Refined

Description

Reddish-brown, mobile liquid with an aromatic odor; [NIOSH]

Sources/Uses

Used as a rubber, adhesive, and coating solvent; "A typical rubber solvent is a mixture of hydrocarbons. It has the chemical composition: 41.4% paraffins, 53.6% naphthalenes (monocycloparaffins), 1.5% benzene, 3.4% alkyl benzenes, and 0.1% olefins." [ACGIH] Separated from coal tar by distillation; "Contains naphthalene, acenaphthene, methylnaphthalenes, fluorene, phenol, cresols, pyridine, picolines, among other substances." [CAMEO] According to HSDB, this CAS number refers to "Naphtha" which is produced by the distillation of petroleum or natural gas, not coal tar. The PEL and IDLH values refer to "Naphtha (coal tar)."

Comments

TSCA Definition 2008: A mixture of natural gas distillates with carbon numbers of C5 to C6 and boiling points of 38 deg C to 93 deg C; [ChemIDplus] Motor incoordination occurs in rats and dogs exposed to concentrations of 5300 ppm. [ACGIH] Inhalation of vapor can cause CNS depression; [CAMEO] See "VM & P Naphtha."

Exposure Assessment
Skin Designation (ACGIH)

Insufficient data

PEL (OSHA)

100 ppm

IDLH (NIOSH)

1000 ppm

Excerpts from Documentation for IDLHs

Other human data: Acute exposure to 430 ppm has been reported to cause only slight eye and throat irritation [Carpenter et al. 1975].

Lethal Concentration

LCLo (rat) = 1,600 ppm/6H

Explanatory Notes

For TLV, see Appendix H: Reciprocal Calculation Method for Certain Refined Hydrocarbon Solvent Vapors; [TLVs and BEIs] IDLH = 10'% LEL (lower explosive limit) Flash point is > 100 deg F; [CAMEO]

Flammability (NFPA)

2: High ambient temperature required
