NFPA 704
General Description
Oily black liquid with an odor of tar. Less dense than water and insoluble in water. Hence floats on water. (USCG, 1999)
Hazards
Reactivity Alerts
none
Air & Water Reactions
Flammable. Insoluble in water.
Fire Hazard
No information available.
Health Hazard
Contact with skin may cause dermatitis. Inhalation of vapors may cause moderate irritation of nose and throat. Hot liquid burns skin. (USCG, 1999)
Reactivity Profile
PETROLEUM ROAD OIL may be ignited by with strong oxidizing agents like nitric acid. Charring may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, mostly unreactive. Not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. Burns exothermically when heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents.
Belongs to the Following Reactive Group(s)
- Hydrocarbons, Aliphatic Saturated
Potentially Incompatible Absorbents
