Platinum tetrachloride

Fresh air, rest. Refer for medical attention.

Remove contaminated clothes. Rinse and then wash skin with water and soap.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .

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: 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.

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/

Dose-dependent forward mutations were induced by PtCl4 to 8-azaguanine resistance (8-AGr/HGPRT locus) in Chinese hamster ovary (CHO-S) cells. In addition there was an increased dose-related frequency of CHO-AUXB1 reversion.

Rabbit alveolar macrophages exposed to the water-soluble platinum(IV) chloride at a concentration of 0.4 mmol/l (78 mg Pt/l) for a period of 20 hr exhibited a 50% reduction in macrophage viability. A reduction in phagocytic activity and a decrease in total cellular adenosine triphosphate to 50% of the value in control macrophages was observed at 0.21 and 0.25 mmol/l (41 and 48 mg Pt/l).

In experiments with rats dose-response relationships of alimentary PtCl2 and PtCl4 were investigated. 2 x 81 animals weighing 35 g were randomly distributed among 9 treatment groups which were fed ad libitum with a synthetic diet containing various amounts of Pt during 4 weeks. Pt was added in the form of PtCl2 or PtCl4 in the amounts 0; 0.01; 0.05; 0.10; 0.50; 1.0; 5.0; 10 and 50 mg/kg diet. The Pt supplementation had no influence on life mass gain or food consumption. In the case of 50 mg/kg Pt in the form of PtCl4 the erythrocyte count and hematocrit were reduced by about 13% in comparison with the control group. Dependent on the Pt dose, the application of PtCl4 and PtCl2 induced Pt retention in nearly all tissues especially in kidney. The effects were greater with PtCl4 than with PtCl2. As a result of the higher Pt retention in the kidneys, the serum creatinine was increased for the higher doses of PtCl4.

Occupational inhalation allergy (bronchial asthma, rhinitis, conjunctivitis), often in association with urticaria and Quincke edema is common in platinum associated industry. It is due to sensitization against platinum chloride. As an avg of 60% of people working in the platinum industry fall ill with bronchial asthma more stringent protective occupational measures are suggested.

Wheezing /in sensitized workers/ can be relieved with bronchodilators and corticosteroids. Complete recovery can be expected if further exposure is avoided. /Chloroplatinates/
