SECTION 3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: Product Description: Halon 1211 is a colorless, liquefied gas, with a sweet odor, shipped under
pressure. Health Hazards: The main acute health hazard associated with releases of this gas is asphyxiation by displacement of
oxygen. This gas is heavier than air and will sink into low areas, creating an asphyxiation hazard. The main chronic health hazard
associated with releases of this gas is possible adverse effects to the central nervous system and possible cardiac sensitization
and arrhythmias. Chronic skin exposure may cause dermatitis. Flammability Hazards: This gas is not flammable. Reactivity
Hazards:
This gas is not reactive. Environmental Hazards: Release of this product to the environment is not expected to cause
environmental harm. Emergency Response Considerations: Emergency responders must wear the proper personal protective
equipment suitable for the situation to which they are responding. WARNING—If rescue personnel need to enter an area suspected
of having a low level of Oxygen, they should be equipped with Self-Contained Breathing Apparatus (SCBA) and appropriate
personal protective equipment.
EU LABELING/CLASSIFICATION: Currently, there is no classification applicable per Directives 67/548/EEC and
1999/45/EC and subsequent Directives.

EYE CONTACT: If mechanical injury occurs, cover eye with bandage and seek appropriate medical attention.
INGESTION: Ingestion is an unlikely route of exposure for this gas.
INHALATION: Remove victim(s) to fresh air, as quickly as possible. Trained personnel should administer supplemental oxygen
and/or cardio-pulmonary resuscitation, if necessary.
SKIN CONTACT: If skin contact causes adverse effects, begin decontamination with warm, running water. Minimum flushing is
for 20 minutes. Remove exposed or contaminated clothing, taking care not to contaminate eyes. Victim must seek immediate
medical attention if any adverse effect occurs. In case of frostbite, place the frostbitten part in warm water. DO NOT USE HOT
WATER. If warm water is not available, or is impractical to use, wrap the affected parts gently in blankets. Alternatively, if the
fingers or hands are frostbitten, place the affected area in the armpit. Encourage victim to gently exercise the affected part while
being warmed. Seek immediate medical attention.
MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: None are anticipated.

SECTION 4. FIRST AID MEASURES (Continued)
NOTES TO PHYSICIANS: Administer oxygen, if necessary, and treat symptoms. This gas 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.
SECTION 5. FIRE FIGHTING MEASURES

NFPA RATING
AUTOIGNITION: Not Applicable
FLAMMABILITY
FLAMMABLE RANGE: Not Applicable
EXTINGUISHING MEDIA: This is a non-flammable gas; use fire-extinguishing
media appropriate for the surrounding materials.
SPECIAL FIRE-FIGHTING PROCEDURES: Non-flammable gas. Use
extinguishing media appropriate for surrounding fire.
INSTABILITY
UNUSUAL FIRE AND EXPLOSION HAZARDS: This gas does not burn;
however, containers, when involved in fire, may rupture or burst in the heat of the
fire. Most cylinders have a pressure release device, which will vent contents if the cylinder is exposed to high temperatures. This gas is heavier than air, creating an asphyxiation hazard in low areas. EXPLOSION SENSITIVITY TO MECHANICAL IMPACT: Not sensitive.
Hazard Scale: 0 = Minimal 1 = Slight 2 = Moderate
EXPLOSION SENSITIVITY TO STATIC DISCHARGE: Not sensitive.
3 = Serious 4 = Severe
HAZARDOUS COMBUSTION PRODUCTS: Combustion or decomposition products above 481.7°C (900°F) include
hydrogen bromide, hydrogen chloride, hydrogen fluoride, free halogens, and small amounts of carbonyl halides. These by-
products have a sharp irritating odor and are dangerous even in low concentrations and in sufficient concentrations can result
in personal injury or death.
SECTION 6. ACCIDENTAL RELEASE MEASURES
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: All release to the environment should be
avoided as this material has an ozone depletion potential and a global warming potential.
In the event of a release of this product, operator should close the gas source if possible to do so safely. Evacuate area in the
event of a significant release. Only trained personnel, wearing Self-Contained Breathing Apparatus (SCBA) should re-enter a
contaminated area if oxygen levels are below 19.5% or unknown.
If leak is in user’s gas handling equipment or system, close cylinder valve, and safely vent high pressure before attempting repairs.
If leak is from the cylinder, cylinder valve or the valve pressure relief device (PRD), contact your supplier.
Detection systems should be available to monitor for level of oxygen. The level of oxygen should above 19.5% before personnel
can be allowed in the area without SCBA.
SECTION 7. HANDLING AND STORAGE
STORAGE: Cylinders should be stored upright (with valve protection caps or plugs in place) and firmly secured to prevent falling
or being knocked over. Cylinders should be stored in dry, well-ventilated areas. Protect from salt or other corrosive materials.
Storage should be away from heavily traveled areas, walkways, elevators, platform edges or other objects or situations that could
damage the cylinder wall. Do not store in a manner that will block emergency exits, fire extinguishers or other safety equipment.
Do not allow storage temperature to exceed 125°F (52°C). Use a first-in, first-out inventory system to prevent full containers from
being stored for long periods of time. Store empty cylinders away from full cylinders. NOTE: Use only DOT or ASME code
cylinders designed for compressed gas storage. Cylinders must not be recharged except by or with the consent of owner.
HANDLING: Releases of Halon 1211 can create an oxygen-deficient atmosphere. Be aware of any signs of dizziness or
fatigue; exposures to fatal concentrations of Helium-3 could occur without any significant warning symptoms, due to oxygen-
deficiency. Wearing contact lenses is not recommended when handling this gas.
Cylinder valves should be inspected regularly for physical damage or corrosion (apparent by discoloration or rust). Care should be
taken to inspect the following valve locations for corrosion: neck (where valve inserts into cylinder); bonnet nut (where handle
attaches to valve body). Close valve after each use and when empty.
Do not drag, roll, slide or drop cylinder. Use a suitable hand truck designed for cylinder movement. Never attempt to lift a cylinder
by its cap. Secure cylinders at all times while in use. Use a pressure regulator to safely discharge product from cylinder. Use a
check valve to prevent reverse flow into cylinder. Once cylinder has been connected to properly purged process, open cylinder
valve slowly and carefully. If user experiences any difficulty operating cylinder valve, discontinue use and contact supplier. Never
insert an object (e.g., wrench, screwdriver, etc.) into valve cap openings; doing so may damage valve, causing a leak to occur.
Use an adjustable strap-wrench to remove over-tight or rusted caps.
Do not heat cylinders by any means to increase the discharge rate of product from the cylinder. Never apply flame or localized
heat directly to any part of the cylinder. Cylinders should not be artificially cooled as certain types of steel undergo property
changes when cryogenically cooled, thus making the cylinder unstable.
PRODUCT USE: This product is used as a fire-extinguishing agent, refrigerant gas and as a cleaning agent.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices
indicated in Section 6 (Accidental Release Measures). Relieve pressure before attempting repairs.

early symptoms in persons with heart, lung, or circulatory problems. For Routine Industrial Use and Handling Applications Breathing increases, especially in exertion. Pulse up. Impaired coordination, perception, and judgment. Hazard Scale: 0 = Minimal 1 = Slight 2 = Moderate
3 = Serious 4 = Severe * = Chronic hazard
Breathing further increases in rate and depth, poor coordination and judgment, lips slightly blue. Mental failure, fainting, unconsciousness, ashen face, blueness of lips, nausea (upset stomach), and vomiting. 8 minutes, may be fatal in 50–100% of cases; 6 minutes, may be fatal in 25 to 50% of cases; 4–5 minutes, recovery with treatment. Coma in 40 seconds, followed by convulsion, breathing failure, death. WARNING: Exposure to atmospheres containing 8–10% or less oxygen will bring about unconsciousness without
warning and so quickly that individuals cannot help or protect themselves. Lack of sufficient oxygen may cause
serious injury or death.

SKIN CONTACT: Transitory skin contact should not cause any adverse effects.
OTHER ACUTE HEALTH EFFECTS: Contact with rapidly expanding gases (which are released from under high
pressure) may cause frostbite. Symptoms of frostbite include change in skin color to white or grayish-yellow. The pain caused
by frostbite can quickly subside, masking the injury. In addition, the sudden release of a pressurized gas (such as may occur
in the event of a valve failure), presents a severe hazard of mechanical injury.
ACUTE EXPOSURE TARGET ORGANS: Respiratory system.
ROUTES OF ENTRY, SYMPTOMS OF CHRONIC EXPOSURE:
INHALATION: In animal tests, rats were exposed by inhalation for 21 days, dosed 6 hours per day, 5 days per week, at
3,300 ppm and no adverse effects of toxicological significance (NOAEL) were observed. 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. Other animal testing resulted in cardiac sensitization at various concentrations
for varying exposure times. Chronic exposure to oxygen-deficient atmospheres (below 18% oxygen in air) may affect the heart
and nervous system.

ACUTE: 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. CHRONIC: A case of occupational rhabdomyolysis in an individual susceptible to malignant hyperthermia was described. A 43 year old male was found to have a serum creatine-kinase activity of 650 international units per liter, normal range 10 to 200 international units/liter, suggesting that he was susceptible to malignant hyperthermia. His susceptibility was confirmed by in vitro testing of a muscle specimen with halothane and caffeine. The subject was subsequently employed in a factory that made fire extinguishers where one of his jobs consisted of discharging Bromochlorodifluoromethane from fire extinguishers before refilling them. Although discharging was done in open air, some gas was commonly inhaled. Eighteen months after beginning this work, he was examined for complaints of malaise and stiffness and weakness in the forearms and hands. The symptoms progressively worsened during the week and improved the weekends. Serum creatine-kinase activity was 1056 IU/l on one Saturday and 544 IU/l the following Monday. Because of the similarity in structure between Bromochlorodifluoromethane and halothane, the effects of the former on contractions of a muscle specimen were examined. Bromochlorodifluoromethane induced contractions identical to those of halothane. The patient was advised to change jobs. After he did so his symptoms immediately improved. It was concluded that the patient's rhabdomyolysis is due to recurring exposures to Bromochlorodifluoromethane. They recommended that persons susceptible to malignant hyperthermia avoid exposure to similar halogenated hydrocarbons. 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. Paresthesia 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. 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. IRRITANCY OF PRODUCT: Not applicable.
SENSITIZATION OF PRODUCT: Halon 1211 is not a human skin or respiratory sensitizer, but has been shown to be a
cardiac sensitizer in animal studies.
REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of Halon 1211 on the
human reproductive system.
Mutagenicity: Halon 1211 is not reported to cause mutagenic effects in humans. Embryotoxicity: Halon 1211 is not reported to cause embryotoxic effects in humans. Teratogenicity: Halon 1211 is not reported to cause teratogenic effects in humans. Reproductive Toxicity: Halon 1211 is not reported to cause adverse reproductive effects in humans. A mutagen is a chemical that causes permanent changes to genetic material (DNA) such that the changes will propagate through generational lines. An embryotoxin is a chemical that causes damage to a developing embryo (i.e., within the first eight weeks of pregnancy in humans), but the damage does not propagate across generational lines. A teratogen is a chemical that causes damage to a developing fetus, but the damage does not propagate across generational lines. A reproductive toxin is any substance that interferes in any way with the reproductive process. BIOLOGICAL EXPOSURE INDICES (BEIs): Currently, Biological Exposure Indices (BEIs) have not been determined for
Halon 1211.

HALON 1211
SECTION 12. ECOLOGICAL INFORMATION
ALL WORK PRACTICES MUST BE AIMED AT ELIMINATING ENVIRONMENTAL CONTAMINATION.
ENVIRONMENTAL STABILITY: The gas will be dissipated rapidly in well-ventilated areas.
EFFECT OF MATERIAL ON PLANTS or ANIMALS: Immediate adverse effect on plants would be related to oxygen-
deficient environments or frost from rapidly expanding gases, unless exposure occurs in a confined space.
EFFECT OF CHEMICAL ON AQUATIC LIFE: There is currently no evidence of adverse effects from exposure to Halon
1211 on aquatic life.
MOBILITY: Using a structure estimation method based on molecular connectivity indices, the Koc for Halon 1211 can be
estimated to be about 49. According to a classification scheme, this estimated Koc value suggests that Halon 1211 is
expected to have very high mobility in soil.
PERSISTENCE AND BIODEGRADABILITY: Photodegradation: > 50% after 14 years. If released to air, a vapor
pressure of 2.07X10+3 mm Hg at 25°C indicates Halon 1211 will exist solely in the gas phase in the ambient atmosphere. Gas
phase Bromochlorodifluoromethane will slowly be degraded in the atmosphere by reaction with photochemically-produced
hydroxyl radicals; the half-life for this reaction in air is estimated to be greater than 44 years. Halon 1211 absorbs very little UV
radiation above 290 nm and is not expected to photolyze at a significant rate in the ambient atmosphere. Volatilization from
moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 9.4X10-2
atm-cu m/mole. Halon 1211 will volatilize rapidly from dry soil surfaces since it exists as a gas in the ambient environment. If
released into water, Halon 1211 is not expected to adsorb to suspended solids and sediment based upon the estimated Koc.
Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's
Law constant. Estimated volatilization half-lives for a model river and model lake are 1.3 hrs and 5.1 days, respectively. Given
its high degree of halogenation, it is not expected to be an important degradation pathway for Halon 1211.
POTENTIAL TO BIOACCUMULATE: An estimated BCF of 5.8 was calculated for Halon 1211, using an estimated log
Kow of 1.9 and a regression-derived equation. According to a classification scheme, this BCF suggests the potential for
bioconcentration in aquatic organisms is low.
OZONE-DEPLETION POTENTIAL: Halon 1211 is rated as 3 (compared to trichlorofluoromethane nominally 1). Halon
1211 is a Class I ozone depleting chemical (40 CFR Part 82). Halon 1211 may contribute to global warming.
