    3.   HAZARD IDENTIFICATION 
                                          Ammonium tetrachloroplatinate(II) is a severe irritant to the eyes and lungs, is 
                                          a mild skin irritant and is toxic if swallowed. It is highly allergenic and will 
                                          cause Type 1 sensitisation in susceptible individuals. Sensitised persons, on 
                                          re-exposure to platinum salts, will show the clinical features of a Type 1 
                                          allergy - asthma and/or rhinitis and/or conjunctivitis and/or urticaria. A contact 
                                          dermatitis can also occur. 聽 
 
    4.   FIRST AID MEASURES 
         First Aid                        Inhalation of the dust will result in coughing and sneezing and severe irritation 
                                          of the respiratory tract, and is the main cause of sensitisation. The symptoms 
                                          of the allergic reaction to platinum salts may include any of the following;- 
                                          itchy red eyes, watering of the eyes, sneezing, runny nose, chest tightness, 
                                          wheezing, breathlessness, cough, eczematous or urticarial (nettle rash type) 
                                          skin lesions. Exposure to platinum salts in exceedingly small amounts, even 
                                          below the level of physico-chemical detection, will produce symptoms in 
                                          sensitised persons. Continued exposure will give symptoms of increasing 
                                          severity and can eventually lead to chronic asthma. There is a risk of 
                                          anaphylactic shock occuring in sensitised persons re-encountering platinum 
                                          salts. Therefore, if sensitisation has developed, further exposure to platinum 
                                          compounds must not be permitted. "Platinum asthma" is a prescribed 
                                          occupational disease in the UK. Ingestion will lead to severe abdominal pain, 
                                          with possible chemical burns to the mouth and throat. Contact with the skin 
                                          will be irritating. Strong solutions are corrosive, with the possibility of burns in 
                                          severe cases. Contact with the eyes will be painful at all levels of exposure. 聽 聽

    5.   FIRE FIGHTING MEASURES 
                                     Although the material is not flammable, toxic fumes will be produced if 
                                     involved in a fire. The residue, ash or char left after a fire may have catalytic 
                                     properties and may promote the re-ignition of flammable materials and 
                                     vapours. Wear self-contained breathing apparatus and personal protective 
                                     equipment. Use any extinguisher suitable for the surrounding fire. 聽 聽 
 
    6.   ACCIDENTAL RELEASE MEASURES 
                                     Evacuate non-protected personnel. Wear protective clothing, impervious 
                                     gloves, eye protection and filter-type respiratory protection when dealing with 
                                     spillages. Solid spills should be carefully collected into a sealable, plastic 
                                     lined drum. Solutions should be absorbed in sand or other inert absorbant 
                                     and carefully transferred to a plastic lined drum. The site of the spillage may 
                                     be treated with an aqueous solution of a reducing agent, to convert any 
                                     remaining platinum compounds to the metal. Store accumulated rags, wipes, 
                                     mops, sand, vermiculite etc. in suitably labelled containers for return to the 
                                     refinery for precious metal recovery. Afterwards, wash the site of the spillage 
                                     with copious amounts of water. If the spill has resulted in the dispersion of 
                                     dust through the air, the area must be decontaminated by thorough washing 
                                     with water. 聽 聽 聽 
 
    7.   HANDLING AND STORAGE 
                                     Good industrial hygiene practices should be observed. Avoid direct contact. 
         Handling (JM) 
                                     Do not eat, drink, smoke or apply cosmetics whilst handling. Exposure to air- 
                                     borne particulates must be kept within permissible limits. Use only under 
                                     conditions of good local ventilation. 聽 聽 聽 聽 聽 聽

                                     Local exhaust extraction should be used. Vapour and fumes from all 
                                     operations should be vented to external atmosphere via a collection or 
                                     scrubbing system. Personal filter type respiratory protection, impervious 
                                     gloves and industrial safety glasses should be worn. Work clothes should be 
                                     changed as often as necessary and at least after every working shift. Wash 
                                     hands after using this material. 
 
                                     Users of large amounts of the solid or its solutions should consider the 
                                     application of engineering control measures, such as total enclosure and 
                                     remote operation where possible. Workplace air and the exhaust from the 
                                     ventilation system should be monitored for airborne platinum to ensure that 
                                     exposure limit are not exceded. This monitoring should include personal 
                                     breathing zone sampling. Pre-exposure and periodic medical examinations of 
                                     persons exposed to platinum salts are recommended. Further details are 
                                     given in the HSE's Guidance Note MS22,"The Medical Monitoring of Workers 
                                     Exposed to Platinum Salts" (ISBN 0 11 883575 0). For non UK residents,

                                         On standing in air, the solid will absorb moisture and may coalesce into a 
                                         hard lump. The acidic, aqueous solution will hydrolyse when subjected to 
                                         heat and light. Old solutions will contain chloro-hydroxy platinum species. 
                                         The solution may be stabilised by the addition of hydrochloric acid. The solid 
                                         decomposes on heating, giving off toxic fumes. 聽

                                         Tetrachloroplatinate, but the LD50 (oral-rat) for the solid is likely to be in the 
                                         range 50 to 200 mg/kg i.e. Toxic. 
                                         However, the solution, (normally 10%) is classified as Harmful. 
                                         Persons with a history of allergic diseases, such as asthma or hay-fever, 
                                         should not work with platinum salts. A history of cardiac or pulmonary 
                                         diseases may also preclude work with platinum salts - medical opinion should 
                                         be sought. Any workers experiencing untoward effects or symptoms should 
                                         be removed from exposure and medically examined for platinum sensitivity. 
                                         Sensitisation is indicated by positive skin-prick test to low concentration 
                                         solutions of platinum salts.
