r DEC -14-'89 09:39 ID:L4 TOLEDO TEL ND:419 _ • TITANIUM TETRACHLORIDE IV. STABILITY stable when stored in an inert atmosphere. Use nitrogen containing less than 10 ppm oxygen. t W91----4efined ..�.,.as-t___JUmmabla _......Or eembeatible. However, the product may support combustion and decompose under fire conditions to give off toxic materials such as hydrogen chloride and chlorine gases. it -.is -trot-"nsitive •to etatic discharge. Products of combustion are irritating to the respiratory tract and may cause breathing difficulty and pulmonary edema. Symptoms may be delayed several hours or longer depending upon the extent of exposure. As in any fire, prevent human exposure to fire, smoke, fumes or products of combustion. Evacuate nonessential personnel from the fire area. Firefighters should wear full -face, self-contained breathing apparatus and impervious protective clothing. If not leaking, keep fire -exposed containers cool with a water spray to prevent rupture due to excessive heat. Do not use high pressure water hose as it may spread product from broken containers increasing contamination or fire hazard. Do not get water inside containers as a vigorous reaction may result, generating high temperatures and pressures. Small Fires: Use dry chemical or carbon dioxide. #509 P06 Large Fires: Flood with water. Copious quantities are required to scrub out the liberated hydrogen chloride and wash away the TiC14 residues. Contaminated buildings, areas and equipment must not be used until they are properly decontaminated. VII. TOx M OGY INGESTION: The acute oral LD50 is less than 464 mg/kg in male rats. A single oral dose of 464 mg/kg produced a severe decrease in physical activity and 100 percent mortality. SKIN CONTACT: The acute dermal LD50 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 LC50 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/I 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). T-4624 Page 2 of 6
