Platinum, soluble salts
Metals, Inorganic Compounds
Appearance and odor vary depending upon the specific soluble platinum salt. [NIOSH]
Platinum is used as a catalyst in petroleum refining and in catalytic converters for automobile exhaust. [ACGIH] Platinum is used in the following industries: automotive, chemical, petroleum, electrical, jewelry, pharmaceutical, ceramics, dental, and plastics. [Harber, p. 473] Platinum chloride used in photography (toner and platinum printing); [www.ci.tucson.az.us/arthazards/medium.html] Workers are exposed to platinum in plants for the production and recycling of catalytic converters; [Reference #2]
The allergenic compounds appear to be limited to the "coordination complexes containing halogen ligands as leaving groups" with the most potent examples being hexa- and tetrachloroplatinates. [Nordberg, p. 1138] Occupational asthma reported in platinum refinery; [Malo] Allergic contact dermatitis in electronics workers; [Marks] Platinum salts can cause immunologic, occupational contact urticaria; [Kanerva, p. 219] There is evidence from pharmacologic use that platinum is nephrotoxic. [Rosenstock, p. 572]

Excerpts from Documentation for IDLHs
Basis for original (SCP) IDLH: Air concentrations at or slightly above the OSHA PEL for soluble platinum salts can elicit an allergic response in sensitized workers. Therefore, the IDLH cannot be set to protect these sensitized individuals. The available toxicological data do not indicate any toxic effects in nonsensitized individuals. Because there is no evidence of an IDLH for nonsensitized individuals, for this draft technical standard, respirators have been selected on the basis of the assigned protection factor afforded by each device up to 2,000 times the OSHA PEL of 0.002 mg Pt/m3 (i.e., 4 mg Pt/m3); only the "most protective" respirators are permitted for use in concentrations exceeding 4 mg Pt/m3.
Melting Point = 1772 degrees C.
