| FIRST AID MEASURES | |
|---|---|
| Inhalation | Move to fresh air. If breathing 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 | Remove contact lenses. Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. |
| 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 should be directed at the control of symptoms and the clinical conditions. Treat frostbitten areas as needed. |
| Treatment | Do not give adrenaline or similar drugs. |
| FIRE-FIGHTING MEASURES | |
|---|---|
| Flash point | Not applicable |
| Ignition temperature | >750 °C (1,382 °F) |
| Lower explosion limit | 14.4 %(V) |
| Upper explosion limit | 33.4 %(V) |
| Suitable extinguishing media |
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. |
| Specific hazards during fire |
Contents under pressure. Flammable. Flash back possible over considerable distance. Container may rupture on heating. Cool closed containers exposed to fire with water spray. Do not allow run-off from fire fighting to enter drains or water courses. Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing. Rapid evaporation of the liquid may cause frostbite. 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 and/or explosion do not breathe fumes. Wear self-contained breathing apparatus and protective suit. No unprotected exposed skin areas. |
| 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. Remove all sources of ignition. Avoid skin contact with leaking liquid (danger of frostbite). Ventilate the area. After release, disperses into the air. Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing. Avoid accumulation of vapours in low areas. 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. |
| HANDLING AND STORAGE | |
|---|---|
| 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. Keep away from heat/sparks/open flames/hot surfaces. - No smoking. Follow all standard safety precautions for handling and use of compressed gas cylinders. Protect cylinders from physical damage. Do not puncture or drop cylinders, 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. |
| Handling |
Open drum carefully as content may be under pressure. The product should only be used in areas from which all naked lights and other sources of ignition have been excluded. Pressurized container. Protect from sunlight and do not expose to temperatures exceeding 50 °C. Do not pierce or burn, even after use. Do not spray on a naked flame or any incandescent material. Do not use in areas without adequate ventilation. Contaminated equipment (brushes, rags) must be cleaned immediately with water. |
| Advice on protection against fire and explosion |
Vapours may form explosive mixture with air. Container hazardous when empty. 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. Take measures to prevent the build up of electrostatic charge. Electrical equipment should be protected to the appropriate standard. |
| Storage | |
| Requirements for storage and containers place |
Keep containers tightly closed in a dry, cool and well-ventilated areas. Pressurized container: Protect from sunlight and do not expose to temperatures exceeding 50 °C. Do not pierce or burn, even after use. Keep away from heat and sources of ignition. Protect cylinders from physical damage. Store away from incompatible substances. Storage rooms must be properly ventilated. Ensure adequate ventilation, especially in confined areas. |
| Further information on storage conditions |
Store in original container. Keep containers tightly closed in a cool, well-ventilated place. Keep away from direct sunlight. |
| EXPOSURE CONTROLS / 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 ventilation 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 insufficient 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. |
