Hazard Predictions

• Corrosive: Reaction products may be corrosive
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive
• Toxic: Reaction products may be toxic

ANTIMONY PENTAFLUORIDE gives off hydrogen fluoride fumes on contact with air (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989).

Bromine pentafluoride produces corrosive fumes in moist air (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989). The compound reacts explosively upon contact with water, evolving oxygen gas, which can result in a fire (Mellor, J.W. 1956. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 2, Supp. 1, p. 172. Longmans, Green and Co Ltd).

Chlorine pentafluoride reacts with water or moisture in the air to produce corrosive hydrofluoric acid and toxic chloride gas (Pilipovich, D. et al., Inorg. Chem., 1967, 6, p. 1918). Interaction with ice at -100 C, or with water vapor above 0 C is vigorous (Christe, K.O. Inorg. Chem. 1972, 11, 1220).

Chlorine trifluoride violently reacts with water or ice to generate hydrogen fluoride (HF) and chlorine (Cl2)( The Chemical Elements and their Compounds, Sidgwick, N.V., Oxford, Oxford University Press, 1950 p. 1156). The release of chlorine trifluoride to the atmosphere rapidly generates two toxic reaction products: HF and chlorine dioxide (Lombardi, D.A. and M.D. Cheng, 1996. "Modeling Accidental Releases of Chlorine Trifluoride to the Atmosphere," Paper No. 96-WP66B.02, presented at the 89th Annual Meeting of the Air and Waste Management Association, Nashville, Tennessee, June 23-26).

OXYGEN DIFLUORIDE violently exploded when a spark was discharged in a 25-70% mixture of oxygen difluoride with oxygen over water (Mellor, J.W. 1956. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 2, Supp. 1, p. 191. Longmans, Green and Co Ltd.).

PHOSPHORUS PENTABROMIDE fumes in air. This compound decomposes in water or moist air to form corrosive hydrogen bromide fumes (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989). In experiments at Argonne National Laboratory, in which it was mixed with water and stirred at room conditions, about 35 percent of the theoretical yield of HBr evolved as a gas in the first minute (Brown, D. F., et al. (2005) Development of the Table of Initial Isolation and Protective Action Distances for the 2004 Emergency Response Guidebook, ANL/DIS-05-2, Argonne National Laboratory, Argonne IL).

PHOSPHORUS PENTACHLORIDE generates hydrogen chloride fumes in air and reacts violently with water to form phosphoric acid and hydrochloric acid. In experiments at Argonne National Laboratory, in which it was mixed with water and stirred at room conditions, about 55 percent of the theoretical yield of HCl evolved as a gas in the first 5 minutes (Brown, D. F., et al. (2005) Development of the Table of Initial Isolation and Protective Action Distances for the 2004 Emergency Response Guidebook, ANL/DIS-05-2, Argonne National Laboratory, Argonne IL).

SILICON TETRAFLUORIDE fumes in air (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989). The compound decomposed exothermically by water or moisture in the air to hydrofluoric acid and silicic acid (Handling 365bet娱乐 Safely, Dutch Association of Safety Experts, Dutch Chemical Industry Association, Dutch Safety Institute, 1980 p. 821).

SULFUR MONOCHLORIDE is decomposed by water, yielding hydrogen sulfide, hydrochloric acid, sulfur dioxide, sulfite, hydrogen sulfide, and thiosulfate (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989). It is very corrosive in the presence of water. It reacts violently with water and strong oxidants to form toxic and corrosive gas; on contact with air, it gives off HCl (Handling 365bet娱乐 Safely, Dutch Association of Safety Experts, Dutch Chemical Industry Association, Dutch Safety Institute, 1980 p. 874)

Tellurium Hexafluoride reacts with water to yield toxic hydrogen fluoride vapors. It emits very toxic fumes of fluoride and tellurium and decomposes in water, acid, and alkali (U.S. Environmental Protection Agency. 1998. Extremely Hazardous Substances (EHS) Chemical Profiles and Emergency First Aid Guides. Washington, D.C.: U.S. Government Printing Office).
