Unstable, explosive substance

Stable under normal temperatures and pressures. Dusts may form an explosion hazard. Boiling with Potassium hydroxide yields a product that, after drying, explodes at 205ºC or when mixed with combustible materials.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Incompatible with /potassium hydroxide/ (boiling with alkali yields a product which, after drying, will explode @ 205 °C or if mixed with combustibles).

An explosively unstable compound.

In fire fighting, the minimum respiratory protection required above 0.002 mg/cu m is a self-contained breathing apparatus with a full facepiece operated in pressure-demand or other positive pressure mode. /Soluble platinum salts/

Persons not wearing protective equipment and clothing should be restricted from areas of spills until cleanup has been completed. If soluble platinum salts or liquids containing soluble salts are spilled, the following steps should be taken: 1. Ventilate area of spill; 2. Collect spilled material in the most convenient and safe manner for reclamation or for disposal in a secured sanitary landfill. Liquids containing soluble platinum salts should be absorbed in vermiculite, dry sand, earth, or a similar material, /Soluble platinum salts/

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.|Eating and smoking should not be permitted in areas where soluble platinum salts or liquids containing soluble platinum salts are handled, processed, or stored. Employees who handle soluble platinum salts or liquids containing soluble platinum salts should wash their hands thoroughly before eating, smoking, or using toilet facilities. /Soluble platinum salts/|Respirators may be used when engineering and work practice controls are not technically feasible, when such controls are in the process of being installed, or when they fail and need to be supplemented. ... If the use of respirators is necessary, the only respirators permitted are those that have been approved by the Mine Safety and Health Admin (formerly Mining Enforcement & Safety Admin) or by the National Institute for Occupational Safety & Health. In addition to respirator selection, a complete respiratory protection program should be instituted which includes regular training, maintenance, inspection, cleaning, and evaluation. /Soluble platinum salts/|Control can only be achieved by preventing the release of the soluble complex platinum salts to the atmosphere of the workshop. Good exhaust ventilation is necessary in platinum refineries. Chemical procedures which may generate these salts should be carried out in ventilated fume cupboards. Open centrifuges should not be used. Good personal hygiene is important. /Platinum compounds/|For more Preventive Measures (Complete) data for AMMONIUM CHLOROPLATINATE (9 total), please visit the HSDB record page.

Irritation of nose and throat|An eye irritant.|The dusts of soluble platinum salts cause a burning sensation in the eyes, lacrimation, and conjunctival hyperemia, sometimes associated with photophobia, which suggests that the corneal epithelium may be involved. /Soluble platinum salts/|Inhalation of the dust of sol platinum salts is irritating. /Platinum/

highly toxic

Three groups of adult male cynomolgus monkeys (Macaca fascicularis) were exposed to either 200 ug/cu m ammonium hexachloroplatinate, 200 ug/cu m ammonium hexachloroplatinate concurrently with 1 ppm ozone, or to 1 ppm ozone only. The animals were exposed by inhalation for 6 hr per day, 5 days per week for 12 wk. Two weeks after the 12 wk exposures, baseline pulmonary function was not significantly affected by the exposure regimens; however, the combination of exposure to ozone and ammonium hexachloroplatinate significantly reduced the concentration of platinum salt and methacholine necessary to increase average pulmonary flow resistance 200% (EC200 resistance). Ozone or platinum exposure alone had no significant effect on these parameters. Platinum and methacholine EC200 resistance values were highly correlated for both platinum exposed groups after exposure. These data indicated that combined ozone and platinum exposure significantly increased specific (platinum) and nonspecific (methacholine) bronchial hyperreactivity more often than did exposure to either ozone or the platinum salt alone. Combined ozone plus platinum exposure also significantly increases the incidence of positive platinum skin tests when compared with the other exposure groups. Similar to the human experience, radioallergosorbent testing for platinum specific antibodies was not as sensitive as direct skin testing in identifying allergic persons.
