Section 4: First-Aid Measures

Description of first aid measures: In case of inhalation: Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the contaminated area is most important. Unconscious persons should be moved to an uncontaminated area, given assisted respiration and supplemental oxygen. Further treatment should be symptomatic and supportive. In case of skin contact: If frostbite or freezing occurs, flush immediately with plenty of lukewarm water (105-115 °F; 41-46 °C). Do not use hot water. If warm water is not available, gently wrap affected parts in blankets. Get immediate medical attention. In case of eye contact: Flush eyes with plenty of water. In case of ingestion: If a large amount is swallowed, get medical attention.

Most important symptoms and effects, both acute and delayed: Inhalation: Effects of exposure to high concentrations so as to displace the oxygen in the air necessary for life are headache, dizziness, laboured breathing and eventual unconsciousness. Eyes: Short-Term Exposure: Frostbite. Long-Term Exposure: No information is available. Skin contact: Short-Term Exposure: Frostbite. Long-Term Exposure: No information is available. Ingestion: No significant adverse effects. Indication of any immediate medical attention and special treatment needed: Treat symptomatically. Show this safety data sheet to a physician or emergency room.

Section 5: Fire-Fighting Measures

Extinguisher media: Suitable extinguisher media: Carbon dioxide, regular dry chemical. Large fires: Use regular foam or flood with fine water spray. Unsuitable extinguishing media: None known. Special hazards arising from the mixture: None known. Advice for fire-fighters: Move container from fire area if it can be done without risk. Cool containers with water spray until well after the fire is out. Stay away from the ends of tanks. Withdraw immediately in case of rising sound from

venting safety device or any discoloration of tanks due to fire. For tank, rail car or tank truck, evacuation radius: 800 meters (½ mile). Use extinguishing agents appropriate for surrounding fire. Cool containers with water spray until well after the fire is out. Apply water from a protected location or from a safe distance. Do not get water directly on material. Reduce vapours with water spray. Avoid inhalation of material or combustion by-products. Stay upwind and keep out of low areas. Consider downwind evacuation if material is leaking. Further information: Standard procedure for chemical fires. Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.

Section 6: Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: Personal precautions: Stop leak if possible without personal risk. Evacuate all personnel from affected area, isolate hazard area and deny entry. Stay upwind and keep out of low areas. Use appropriate protective equipment. Environmental precautions: Prevent spreading of vapours through sewers, ventilation systems, and confined areas.

Methods for containment and cleaning up: If leak is in container or container valve, contact your closest supplier location or call the emergency telephone number listed herein.

Reference to other sections: Treat recovered material as described in the section "Disposal considerations".

Section 7: Handling and Storage

Precautions for safe handling: Advice on safe handling: Use only in well-ventilated areas. Valve protection caps must remain in place unless cylinder is secured with valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a pressure-reducing regulator when connecting cylinder to lower pressure piping or systems. Do not heat cylinder by any means to increase the discharge rate of product from cylinder. Use a check valve or trap in the discharge line to prevent hazardous backflow into the cylinder. Hygiene measures: Do not eat, drink or smoke when using this product.

Conditions for safe storage, including incompatibilities: Requirements for storage areas and containers: Protect cylinders from physical damage. Store in cool, dry, well- ventilated area, away from heavily trafficked areas and emergency exits. Do not allow the temperature where cylinders are stored to exceed 125 °F (52 °C). Cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Full and empty cylinders should be segregated. Use a "first in - first out" inventory system to prevent full cylinders from being stored for excessive periods of time.

Section 8: Exposure Controls/Personal Protection

Control parameters: Occupational exposure limits: Contains no substances with occupational exposure limit values.

Exposure controls: Appropriate engineering controls: Provide local exhaust ventilation system. Ensure compliance with applicable exposure limits.
