DEC -14-'e9 09:37 ID:L6 TOLEDO TEL NL:419-24*21 ki5F19 FO -1 Skin Contact The acute dermal LD,, is 3160 mg/kg in rabbits. A single dermal application of 1000 mg/kg did not produce symptoms of toxicity in rabbits. Local effects included moderate to severe necrosis and edema. Inhalation The acute inhalation L.C,, is 0.4 mg/L in rats for a four-hour inhalation exposure. The cause of death appeared to be pulmonary edema. Repeated inhalation exposures in rats to 0.04 mg/L for 6 hours per day, five days per week, for four weeks produced decreased weight gain, inflammation of the respiratory tract, pulmonary fibrosis and 8 percent mortality. Similar treatment to 0.005 mg/L showed no treatment-related effects (Kelly, et al., 1981). See also Section B above, R. What compounds does MI. form on exposure to air? Hydrolysis of TiCI, produces titanium oxychloride, titanium oxides and hydrogen chloride. Reaction with other compounds produces other products, some of which could be potentially harmful. E, if we have a spill of the chemicol compound stored on location, how should we react during the initial period before the vendor can be contacted? If a spill or release occurs, the following steps should be taken: 1. Contain the spill, For a large ground or floor spill, blanket the liquid with Hazmet,1-2 Foam (National Foam Co.); this will allow the TiCi, to slowly hydrolyze to hydrochloric acid without excessive fuming. 2. When the reaction subsides, neutralize the spilt with soda ash and flush away with large amounts of water. 3. Operators and safety personnel should wear full protective clothing and respiratory protection during the entire cleanup procedure. 4. For small spills, wash with large amounts of water and neutralize with soda ash, or mop up with wet rags. Employees should wear rubber gloves and face shields. Danger and Safe Areas Vapor cloud dispersion and dissipation rates are dependent upon variables of terrain configuration and atmospheric conditions. Dispersion rate models have been designed to accommodate single compounds only. However, since TiCI; hydrolyzes to form intermediate titanium oxychloride and hydrogen chloride before decomposing to titanium oxide and hydrogen chloride, these dispersion rate models may not apply. Precautions A. What precautions has Akzo taken to prevent an emergency escape/release? All tank truck shipments of TiCl, are equipped as follows: A 35 -pound rupture disk is followed by stainless steel piping equipped with a'A-turn ball valve. The valve handle is sealed (with a breakable seal) in the open position. A waterproof tag is attached to the valve. The tag reads: "If valve is closed, or seal broken, contact carrier immediately." The phone number is on the tag. B. What procedures should we (the customer) take to prevent an emergency escape/release? To minimize the possibility of accidental release of material to the environment, you should adhere to a routine physical inspection of storage tanks (i.e., ultrasonic testing for internal corrosion; testing of relief valves), and ensure that the scrubber is not backed up into the tank.
