Evaporation from the skin can produce chilling sensations. Skin injury does not result. Inhalation:Exposure to concentrations of this material above 4% for longer than one minute can cause toxic side effects. These can include dizziness, imjpaired coordination, reduced mental acuity and cardiac effects. Higher concentrations with longer exposures can cause unconsciousness or even death. Ingestion:Ingestion is not likely to occur since this material is a gas at room temperature. Chronic Overexposure:None known. Medical conditions generally aggravated by exposure:  Cardiac problems. For Environment:Relative to the environment, this material has an ozone depletion potential and a global warming potential. See Heading 12.4.First Aid Measures Eye Contact:Immediately flush eyes with plenty of water for at least 15 minutes while holding lids open. If redness, itching or a burning sensation develops, get medical attention. Skin Contact:Wash the material off the skin with copious amounts of soap and water for at least 15 minutes. If redness, itching or a burning sensation develops, get medical attention. Inhalation:Remove victim to fresh air. If cough or other respiratory systems occur, consult medical personnel. If not breathing, give artificial respiration, preferably mouth-to-mouth. If breathing is difficult, give oxygen. Consult medical personnel. Ingestion:If patient is conscious, give 1 or 2 glasses of warm water to drink and get medical attention. DO NOT INDUCE VOMITING. Have victim lie down and keep warm. NOTE TO PHYSICIAN: Product is an asphyxiant and can induce cardiac muscle sensitization to circulating epinephrine-like compounds. Do NOT give adrenalin or similar sympathomimetic drugs. Do NOT allow victim to exercise until 24 hours following specific exposures. Freeze burns of mucosal tissue can develop following specific exposures.5.Firefighting Measures This preparation is an extinguishing media.Use water to cool fire exposed cylinders or other containers.Containers are equipped with pressure and temperature relief devices, but rupture may occur under fire conditions and toxic decomposition by-products may be formed if used in fires over 900蚓.There are NO extinguishing media which must not be used for safety reasons.Self-contained breathing apparatus with full facepiece and protective clothing when re-entering unventilated fire areas where product has been used.6.Accidental Release Measures For personal protection: Prevent skin and eye contact, see Heading 8.Evacuate area, ventilate to outside atmosphere.Cool or remove hot metal surfaces or source of non-extinguished flames.Clean up: This product will vaporize and dissipate into the atmosphere. See Heading 13.Relative to the environment, this material has an ozone depletion potential and a global warming potential. See Heading 12.7.Handling and Storage7.1Handling Care should be taken in handling all chemical substances and preparations.See incompatibility information in Heading 10.7.2Storage Store as a liquified compressed gas in DOT approved pressure vessels away from high temperatures.If cylinder is not connected to a system, it must be safety capped to protect against actuation of valve and release of agent.See incompatibility information in Heading 10.Relative to the environment, this material has an ozone depletion potential and a global warming potential. See Heading 12.7.3Specific use The intended or recommended use of this preparation is as a fire extinguishing agent.8.Exposure Controls/Personal Protection8.1Exposure limit values Limit Values for Exposure:  None known.8.2Exposure controls 8.2.1Occupational exposure controls protection   Mechanical ventilation is recommended in low areas or indoors where vapours may collect.Local exhaust is recommended for most exposures.Not normally necessary if controls are adequate. For high concentrations exceeding 4%, or if exposure is prolonged, use positive pressure air supplied respirator. protection   Use plastic gloves when handling the liquid. protection   Chemical goggles recommended as mechanical barrier.Full faceshield is addition if splashing of liquid form is possible. protection   Standard work clothes should provide all protection which is necessary. 8.2.2Environmental exposure controls  Relative to the environment, this material has an ozone depletion potential and a global warming potential.

These by-products have a sharp irritating odour. They are dangerous even in low concentrations and in sufficient concentrations can result in personal injury or death.11.Toxicological Information Product:Acute Toxicity Data:Inhalation LC50 (rat)225,000 ppm. Above 6% caused tremors, narcotic paralysis, spasms and respiratory disorders. Inhalation LC50 (rat)31,300 ppm/4 hrs. Inhalation LC50 (rat)200,000 ppm/15 min. Inhalation (rat)At 50,000 ppm, no effects were noted. At 75,000 ppm, slightly accelerated respiration was noted. At 100,000 ppm, mild excitement was seen. At 200,000 ppm, within 1 to 2 minutes marked excitation and some convulsions were noted. At 60 to 90 minutes, 2 of the 4 animals died. A concentration of 300,000 ppm immediately gave rise to convulsions and narcosis and all animals died within 50 min. Inhalation (dog)At 25,000 to 75,000 ppm for 3.5 hours, there was reversible myocardial lesions and fatty degeneration of the liver.Acute Irritation Data:Skin (rabbit)Eye (rabbit)Not irritatingNot irritatingChronic Toxicity Data:Inhalation (rat), for 21 days, dosed 6 hours per day, 5 days per week, at 3,300 ppm. No adverse effects of toxicological significance (NOAEL). At 10,000 ppm, there were signs of central nervous system depression. However, there were no signs of toxicity or histopathological changes observed and no potentiation of cardiac sensitization potential.Arnes Test:NegativeReproduction Toxicity:Inhalation (rat), at 5,000, 10,000 and 15,000 pm. Neither maternal or foetal toxicity was observed.Other Information:Inhalation (dog): At 5,000 to 100,000 ppm resulted in cardiac sensitization above 20,000 ppm and in 10 to 0.5 minutes, depending on concentration.Inhalation (human): At 4 to 5% for 1 minute using face mask, subjects at 30 seconds became slightly dizzy and light headed. Over the next few seconds, these symptoms rapidly increased in severity until at 1 minute the subjects felt as though they were about to lose consciousness and exposure was stopped. Paraesthesia of the fingers and other parts of the body was sometimes noted towards the end of the experiment. Heart rate rose by approximately 30% during the early stages of exposure and remained at that level through the experiment. Depression of the T wave was consistently observed on the ECG tracings. The subjects recovered rapidly on cessation of exposure and felt perfectly normal again within 5 minutes. The heart rate and the ECG reverted to normal within 1 minute. There were no delayed after effects.12.Ecological Information12.1Ecotoxicity Not determined because of complete partition to the atmosphere.12.2Mobility Bromochlorodifluoromethane is a low boiling point gas and is practically insoluble in water.12.3Persistence and degradability Photodegradation:   >50% after 14 years12.4Bioaccumulative potential Not determined.12.5Other adverse effects Ozone depletion potential:  Rated as 3 compared to trichlorofluoromethane nominally 1. Photochemical ozone creation potential:  None Global warming potential:  May contribute to global warming.13.Ecological Information Relative to the environment, this material has an ozone depletion potential and a global warming potential.
