International Chemical Safety Cards BROMINE PENTAFLUORIDE ICSC: 0974 BROMINE PENTAFLUORIDE BrF5 Molecular mass: 174.9 CAS # 7789-30-2 RTECS # EF9350000 ICSC # 0974 UN # 1745 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. NO contact with flammable substances. NO contact with water, combustible and organic compounds. In case of fire in the surroundings: only use carbon dioxide, dry sand or powder. NO water or hydrous agents. EXPLOSION Risk of fire and explosion on contact with water or steam, fuels and organic compounds. In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water. Combat fire from a sheltered position. EXPOSURE AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! INHALATION Burning sensation. Cough. Shortness of breath. Sore throat. See Notes. Closed system and ventilation. Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention. SKIN Skin burns. Pain. Blisters. Protective gloves. Protective clothing. Remove contaminated clothes. Refer for medical attention. Wear protective gloves when administering first aid. EYES Pain. Blurred vision. Severe deep burns. Safety goggles and face shield, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Abdominal pain. Burning sensation. Do not eat, drink, or smoke during work. Wash hands before eating. Do NOT induce vomiting. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Consult an expert! Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in vermiculite, earth, dry sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Do NOT absorb in saw-dust or other combustible absorbents. NEVER direct water jet on liquid (extra personal protection: complete protective clothing including self-contained breathing apparatus). Separated from food and feedstuffs and all other substances (see Chemical Dangers). Dry. Well closed. Keep in a well-ventilated room. Airtight. Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

International Chemical Safety Cards BROMINE PENTAFLUORIDE ICSC: 0974 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: PALE YELLOW TO COLOURLESS LIQUID , WITH PUNGENT ODOUR. AT TEMPERATURES ABOVE 40.5°C, COLOURLESS GAS WITH PUNGENT ODOUR. PHYSICAL DANGERS: The vapour is heavier than air. CHEMICAL DANGERS: The substance decomposes on heating above 460°C and on contact with acid or acid fumes producing very toxic fumes of fluorine (see ICSC # 0046) and bromine (see ICSC # 0107). Reacts violently with fuels and organic compounds, hydrogen containing material (such as ammonia, acetic acid, grease, paper) causing fire and explosion hazard. Reacts explosively with water or steam to produce toxic and corrosive fumes. Reacts with all known elements, except nitrogen, oxygen and rare gases. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: 0.1 ppm; 0.72 mg/m3 (ACGIH 1991-1992). OSHA PEL: none NIOSH REL: TWA 0.1 ppm (0.7 mg/m3) NIOSH IDLH: No data ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour. INHALATION RISK: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance and vapour are corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema (see Notes). Exposure may result in death. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. PHYSICAL PROPERTIES Boiling point: 40.5°C Melting point: -61.3°C Relative density (water = 1): 2.5 Solubility in water: reacts Vapour pressure, kPa at 25.5°C: 53.5 Relative vapour density (air = 1): 6.1 ENVIRONMENTAL DATA It is strongly advised not to let the chemical enter into the environment because it persists in the environment. N O T E S Reacts violently with fire extinguishing agents such as water. Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Do NOT take working clothes home. Transport Emergency Card: TEC (R)-51G07 NFPA Code: H 4; F 0; R 3; W; OXY ADDITIONAL INFORMATION ICSC: 0974 BROMINE PENTAFLUORIDE © IPCS, CEC, 1993
