Description

Viscous semi-solid to solid; [EPA ChAMP] Yellowish-green to dark brown liquid with an odor of asphalt; [Total Petrochemicals MSDS]

Sources/Uses

Used in the petroleum refining, construction, paving/road making, roofing, and coatings (paints, lacquers, and varnishes) industries; Used as a fuel, adhesive/binding agent, impregnation agent, intermediate, lubricant and additive, stabilizer, asphalt, heating oil, oil refinery processing aid, and waterproofing agent; [IUCLID] Used in petroleum refineries, in adhesives and sealants, and for other applications; [EPA ChAMP]

Comments

TSCA Definition 2008: Obtained from the vacuum distillation of the residuum from atmospheric distillation of crude oil and consisting of hydrocarbons with carbon numbers greater than C34 and boiling point above 495 deg C; [ChemIDplus] The fumes produced from heating (often necessary in applications such as paving) are considered the major occupational hazard of these complex mixtures; [EPA ChAMP] May contain hydrogen sulfide in vapor space of storage container or vessel (heating increases this risk); Contains PAHs; May cause irritation; Harmful by ingestion (may cause lung damage by aspiration); [Total Petrochemicals MSDS] See "Hydrogen sulfide" and "Asphalt fumes."
