Comments |
Petroleum distillates, e.g., VM & P naphtha and kerosene, can cause anesthesia, slowing of reflexes and dermatitis. They may contain n-hexane with the potential to cause peripheral neuropathy. [LaDou, p. 500-1] With regard to potential liver injury, fatty infiltration may be seen after heavy exposures to petroleum distillates, but "frank necrosis is uncommon." [Haddad, L.M., Clinical Management of Poisoning and Drug Overdose. 2nd ed. Philadelphia, PA: W.B. Saunders Co., 1990.(Reference in HSDB for petroleum distillates)] Petroleum ether is in the list of "Some volatile substances which may be abused by inhalation" published on the web site of the U.N. International Drug Control Programme, indicating its potential to cause narcosis in workers. [Reference #1] |
