Routes of exposure Signs and symptoms of exposure: Emergency and first aid procedures:

Skin: Not expected to produce irritation or corrosivity to the skin If significant exposure occurs, wash exposed area immediately with large amounts of water. Remove contaminated clothing and footwear. Contact a physician if irritation occurs. Ingestion: Not likely to occur in industrial use. Volatile liquid. Do not induce vomiting; Call a doctor.

Eyes: Not expected to cause irritation to the eyes. Flush eyes with fresh water and move exposed person to a non-contaminated area. Call a doctor if irritation or effects

occur. Inhalation: Gross overexposure may cause central nervous system effects such as dizziness, confusion, physical incoordination, drowsiness, anesthesia, or unconsciousness. At concentrations of 1.0% (v/v) or higher may cause increased sensitivity of the heart to adrenaline which might cause irregular heartbeats and possibly ventricular fibrillation or death. Remove person to fresh air and keep comfortable for breathing. Call a doctor if breathing difficulties occur.

5. FIRE FIGHTING MEASURES

Flammable Properties

Flash Point: None Flash Point Method: ASTM D92, Standard Test Method for Flash and Fire Points by C leveland Open Cup Tester Auto-ignition Temperature: No ignitions witnessed in tests up to 607° C. Auto-ignition Temperature Method: ASTM E659, Standard Test Method for Auto-ignition Temperature of Liquid Chemicals Upper Flammability Limit (volume % in air): Not applicable Lower Flammability Limit (volume % in air): Not applicable Flammability Limit Method: ASTM E681, Standard Test Method for Concentration Limits of Fl ammability of Chemicals (Vapors and Gases
Extinguishing Media: The properties of this chemical make it an ideal ex tinguishing media itself
Special Fire Fighting Procedures: In the case of a fire involving a bulk tank of the material, ensure that the area where the fire occurred is well ventilated before r e-entering. Wear protective clothing, including a S elf Contained Breathing Apparatus (SCBA), if large amounts are pr esent. Use water spray or fog to cool storage cont ainers to help prevent an uncontrolled pressure release of bulk ta nks, if applicable
Unusual Fire and Explosion Hazards: The concentrated agent when applied to fire can pr oduce toxic by-products specifically hydrogen halides, which can cause dama ge. Avoid inhalation of these materials by evacuat ing and ventilating the area
This material in air at both elevated pressure and temperature levels not commonly encountered may bec ome combustible. Whether a mixture containing this mat erial and air, or oxygen enriched environment, beco mes combustible depends on the inter-relationship of 1) the temperature, 2) the pressure, and 3) the propo rtion of oxygen. Weak combustion of vapors has been witness ed in air mixtures at pressures of 4.3 psig (19.0 p sia) and 302°F (150°C) using a fuse wire ignition source. This agent is extremely effective as a fire extingu ishing agent where it will be applied to a fire as a spray or st ream. This material should not, however, be used i n firefighting applications or other applications where mixtures i n air exceeding a few psig would be expected

In Case of Spill or Other Release: In the event of a large spill, allow for adequate v entilation, and do not re-enter an area without an SCBA until adequate ventilation is accomplished
• For spills that might result in overexposure, ev acuate the area and use protective gear and SCBA’s. • Avoid leakage into waterways. • Do not expose storage containers to fire, as unc ontrolled pressure releases may result
Although this material is volatile and will quickly evaporate, avoid leakage into waterways. For large spills evacuate downwind of the spills and dike to contain the spill until it evaporates

7. HANDLING AND STORAGE
Normal Handling: (See section 8 for recommended personal protective equipment.) Avoid prolonged contact with the skin and eyes. Avoid unnecessarily inhaling mat erial and ensure that good ventilation is present w hen handling. Wash after handling and follow good personal hygien e and good housekeeping practices. Keep containers closed and transfer material using closed systems. Handle in a manner to minimize spills.
Storage: Store in well-ventilated place. Keep container ti ghtly closed. Store locked up

Additional Note: Containers should be maintained in good condition . Do not allow material to remain in deteriorating containers. Because this product can volatilize, special care should be taken for over pressurization hazards if the containers are overheated or near a radiant heat source. Protective shoes, such as ste el toed shoes, should be worn in addition to the other specified p ersonal protective equipment (PPE) when handling bu lk containers. Eye protection with splash protective side shields should be used when any possibility of splash or spray exists.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls: Ventilate as necessary to minimize exposure levels. Inspect and clean ventilation systems regularly. Prolonged use should occur only in areas with adequate ventilation. Keep storage containers tightly closed. Vapors are heavier than air posing a potent ial hazard if large volumes are trapped in enclosed or low places
Personal Protective Equipment: Wear protective clothing when handling a leak in a storage container (does not apply to fire protection equipment servicing, other than safety goggles and gloves if large volumes ca n be exposed to skin). Neoprene, PVC or PVA gloves should be worn w hen handling material for prolonged periods. Short exposures to skin are not likely to pose a hazard. Respiratory protection is not normally needed, howe ver, if handled in enclosed spaces where applicable exposure limits might be exceeded, a Self Contained Breathing Appa ratus (SCBA) should be used. When performing filling or s ervicing operations, Perform These Activities In A WellVentilated Area . If handling the material in poorly ventilated ar eas, use proper respiratory protection. If handling materials outside a closed, sealed system such that the possibility of splashing exists, wear safety g lasses with side shields. This statement is not intended to apply t o use of a fire extinguisher where the nozzle arran gement is intended to direct the discharge away from the user of the extinguisher.
Emergency Overview: Halotron® BrX is a clear and colorless, or clear with a light yellow tint, volatile liquid with a slight ether-like odor (unstabilized), or a soure d fruit odor (when stabilized). As with any chemica l, dose and exposure are critically important variables to unde rstand any potential treatment. Gross overexposure may cause central nervous system effects such as dizziness, c onfusion, physical incoordination, drowsiness, anes thesia, or unconsciousness. Sustained exposure concentrations of 1.0% (v/v) or higher may cause increased sensiti vity of the heart to adrenaline which might cause irregular hea rtbeats and possibly ventricular fibrillation or de ath.

Health Hazards: Time Weighted Exposure Limits: (For persons regular ly exposed to material) - DNEL = 11 ppm
