SECTION 2. HAZARDS IDENTIFICATION

Emergency Overview

Form : Liquefied gas

Color : colourless

Odor : slight

Hazard Summary : Warning! Container under pressure. Flammable. Gas reduces oxygen available for breathing. Causes asphyxiation in high

concentrations. The victim w ill not realize that he/she is suffocating. Inhalation may cause central nervous system effects. May cause cardiac arrhythmia. May cause drowsiness and dizziness. Do not breathe vapour. Irritating to eyes and

skin. Avoid contact with skin , eyes and clothing. At higher temperatures, (>250 C), decomposition products may include hydrofluoric acid (HF) and carbonyl halides. The ACGIH Threshold Limit Values (2007) for Hydrogen Fluoride are TLV-TWA 0.5 ppm and Ceiling Exposure Limit 2 ppm.

Potential Health Effects

Skin : Avoid skin contact with leaking liquid (danger of frostbite). May cause frostbite. Irritating to skin.

Eyes : Causes severe eye irritation. May cause frostbite.

Page 2 / 9 Inhalation : Gas reduces oxygen available for breathing. Causes asphyxiation in high conc entrations. The victim will not realize that he/she is suffocating. Inhalation may cause central nervous system effects. May cause cardiac arrhythmia. Vapours may cause drowsiness and dizziness.

Chronic Exposure : None known.

Carcinogenicity

No component of this product present at levels greater than or equal to 0.1% is identified as a known or anticipated carcinogen by NTP, IARC, or OSHA.

SECTION 3. COMPOSITION/IN FORMATION ON INGREDIENTS

Component CAS-No. Weight %

1,1-Difluoroethane 75-37-6 100.00

SECTION 4. FIRST AID MEASURES

Inhalation : Move to fresh air. If breathi ng is irregular or stopped, administer artificial respiration. Use oxygen as required, provided a qualified operator is present. Call a physician. Do not give drugs from adrenaline-ephedrine group.

Skin contact : After contact with skin, wash immediately with plenty of water. If there is evidence of frostbite, bathe (do not rub) with lukewarm (not hot) water. If water is not available, cover with a clean, soft cloth or similar covering. If symptoms persist, call a physician.

Eye contact : Rinse immediately with plen ty of water, also under the eyelids,

for at least 15 minutes. In case of frostbite water should be lukewarm, not hot. If symptoms persist, call a physician.

Ingestion : Unlikely route of exposure. As this product is a gas, refer to the inhalation section. Do not induce vomiting without medical advice. Call a physician immediately.

Notes to physician

Treatment : Because of the possible disturbances of cardiac rhythm, catecholamine drugs, such as epinephrine, should be used with special caution and only in situations of emergency life support. Treatment of overexposure shoul d be directed at the control of symptoms and the clinical conditions. Treat frost-bitten areas as

needed.

Page 3 / 9 SECTION 5. FIRE-FIGHTING MEASURES

Flash point : not applicable

Ignition temperature : 455 °C (851 °F)

Lower explosion limit : 3.7 %(V)

Upper explosion limit : 18 %(V)

Flammability (solid, gas) : Extremely flammable gas.

Suitable extinguishing

media : Flammable.

ASHRAE 34 In case of fire, allow gas to burn if flow cannot be shut off immediately. Apply water from a safe distance to cool container and protect surrounding area. Extinguishing media - small fires Carbon dioxide (CO2) Dry chemical Extinguishing media - large fires Water spray

Specific hazards during fire fighting : Flammable. Contents under pressure. Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing. Flash back possible over considerable distance. Fire or intense heat may cause violent rupture of packages. Cool closed containers exposed to fire with water spray. Do not allow run-off from fire fighting to enter drains or water

courses. In case of fire hazardous decomposition products may be produced such as: Hydrogen fluoride

Carbon monoxide Carbon dioxide (CO2) Carbonyl halides

Special protective equipment for fire-fighters : In the event of fire, wear self-contained breathing apparatus. In the event of fire and/or explosion do not breathe fumes. Wear self-contained breathing apparatus and protective suit. No unprotected exposed skin areas.

SECTION 6. ACCIDENTAL RELEASE MEASURES

Personal precautions : Immediately evacuate personnel to safe areas. Keep people away from and upwind of spill/leak. Wear personal protective equipment. Unprotected persons must be kept away.

Page 4 / 9 Remove all sources of ignition. Pay attention to flashback. Avoid skin contact with leaking liquid (danger of frostbite). Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing. Avoid accumulation of vapours in low areas. Provide adequate ventilation. Unprotected personnel should not return until air has been

tested and determined safe. Ensure that the oxygen content is >= 19.5%.

Environmental precautions : Prevent further leakage or spillage if safe to do so. The product evaporates readily.

Methods for cleaning up : Ventilate the area.

SECTION 7. HANDLING AND STORAGE

Handling

Handling : Handle with care. Avoid inhalation of vapour or mist. Do not get in eyes, on skin, or on clothing. Wear personal protective equipment. Use only in well-ventilated areas.

Pressurized container. Protect from sunlight and do not expose to temperatures exceeding 50 °C. Follow all standard safety precautions for handling and use of compressed gas cylinders. Use authorized cylinders only. Protect cylinders from physical damage. Do not puncture or drop cylinder s, expose them to open flame or

excessive heat. Do not pierce or burn, even after use. Do not spray on a naked flame or any incandescent material. Do not remove screw cap until immediately ready for use. Always replace cap after use.

Advice on protection against fire and explosion : Container hazardous when empty.

Prevent the creation of flammable or explosive concentrations of vapour in air and avoid vapour concentration higher than the occupational exposure limits. Keep product and empty container away from heat and sources of ignition. The heavy vapours can overcome a considerable distance up to the source of ignition.

Storage

Requirements for storage

areas and containers : Pressurized container: Protec t from sunlight and do not expose to temperatures exceeding 50°C. Do not pierce or burn, even

after use. Keep containers tightly closed in a dry, cool and well-ventilated

Page 5 / 9 place. Keep away from heat and sources of ignition. Storage rooms must be properly ventilated. Ensure adequate ventilation, especially in confined areas. Protect cylinders from physical damage. Store away from incompatible substances. Store in original container.

SECTION 8. EXPOSURE CONTRO LS / PERSONAL PROTECTION

Protective measures : Do not breathe vapour. Avoid contact with skin, eyes and clothing. Ensure that eyewash stations and safety showers are close to

the workstation location.

Engineering measures : General room vent ilation is adequate for storage and handling. Perform filling operations only at stations with exhaust

ventilation facilities.

Eye protection : Do not wear contact lenses. Wear as appropriate: Safety glasses with side-shields If splashes are likely to occur, wear: Goggles or face shield, giving complete protection to eyes

Hand protection : Leather gloves In case of contact through splashing: Protective gloves Neoprene gloves Polyvinyl alcohol or nitrile- butyl-rubber gloves

Skin and body protection : Avoid skin contact with leaking liquid (danger of frostbite). Wear cold insulating gloves/face shield/eye protection.

Respiratory protection : In case of insu fficient ventilation wear suitable respiratory equipment. Wear a positive-pressure supplied-air respirator. Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing. For rescue and maintenance work in storage tanks use self-contained breathing apparatus.

Hygiene measures : Handle in accordance with good industrial hygiene and safety practice. Ensure adequate ventilation, especially in confined areas. Avoid contact with skin, eyes and clothing. Remove and wash contaminated clothing before re-use. Keep working clothes separately. When using, do not eat, drink or smoke.
