Hazard statements

see section 16 H280 - Contains gas under pressure; may explode if heated May displace oxygen and cause rapid suffocation see section 16 4.1. Description of necessary first-aid measures First-aid measures general Calla physician immediately. First aider: Pay attention to self-protection. Never give anything by mouth to an unconscious person. Give artificial respiration if necessary. Induce artificial respiration with mask fitted with one-way valve or other suitable device but, not mouth-to-mouth. First-aid measures after inhalation Remove person to fresh air and keep comfortable for breathing. If the victim is unconscious: Lay in a stable manner on victim's side. Induce artificial respiration with mask fitted with one-way valve or other suitable device; not mouth-to-mouth. Call a physician immediately. First-aid measures after skin contact If frostbite has occurred, seek medical attention immediately; do NOT rub the affected areas or flush them with water. In order to prevent further tissue damage, do NOT attempt to remove frozen clothing from frostbitten areas. If frostbite has NOT occurred, immediately and thoroughly wash contaminated skin with soap and water. First-aid measures after eye contact If eye tissue is frozen, seek medical attention immediately; if tissue is not frozen, immediately and thoroughly flush the eyes with large amounts of water for at least 15 minutes, occasionally lifting the lower and upper eyelids. If irritation, pain, swelling, lacrimation, or photophobia persist, get medical attention as soon as possible. First-aid measures after ingestion Rinse mouth. Do NOT induce vomiting. If vomiting occurs, the head should be kept low so that vomit does not enter the lungs. Call a physician immediately. 4.2. Most important symptoms/effects, acute and delayed Symptoms/effects after inhalation In high concentrations may cause asphyxiation. Symptoms/effects after skin contact Contact with the liquefied gas may cause frostbite. Symptoms/effects after eye contact Contact with the liquefied gas may cause severe ocular lesions. Symptoms/effects after ingestion Not expected to present a significant ingestion hazard under anticipated conditions of normal use. US - en 21 Most Important Symptoms/Effects In high concentrations may cause asphyxiation. Symptoms may include loss of mobility/consciousness. Victim may not be aware of asphyxiation. May cause frostbite on contact the liquefied gas. 4.3. Indication of immediate medical attention and special treatment needed, if necessary Other medical advice or treatment In the event of contact with the liquid: treat resulting frostbite as a burn. Call a physician immediately. 5.1. Suitable (and unsuitable) extinguishing media Suitable extinguishing media Use extinguishing media appropriate for surrounding fire. Dry chemical, CO2, or water spray or regular foam. Sand. Unsuitable extinguishing media Do not use a heavy water stream. 5.2. Specific hazards arising from the chemical Fire hazard Contains gas under pressure; may explode if heated. Explosion hazard Heat may build pressure, rupturing closed containers, spreading fire and increasing risk of burns and injuries. Hazardous decomposition products in case of fire Toxic fumes may be released. Carbon dioxide. Carbon monoxide. Hydrogen fluoride. Halogenated compounds. Carbonyl halides. 5.3. Special protective equipment and precautions for fire-fighters Firefighting instructions No action shall be taken without appropriate training or involving any personal risk. Do not enter fire area without proper protective equipment, including respiratory protection. Use extinguishing media appropriate for surrounding fire. Move containers from fire area if it can be done without personal risk. Damaged cylinders should be handled by specialists only. Large fires: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool affected containers with flooding quantities of water. Do not throw water directly on point of leakage or security devices; freezing may occur. Withdraw immediately in case of rising sound from venting devices or discoloration from tank. ALWAYS stay away from tanks engulfed in fire. Prevent fire- fighting water from entering environment. Protection during firefighting Do not attempt to take action without suitable protective equipment. Self-contained breathing apparatus. Complete protective clothing. 6.1. Personal precautions, protective equipment and emergency procedures General measures Do not take actions involving personal risks. Avoid all personal contact including breathing in the gas. Before entering an area, especially a confined area, check the atmosphere with an appropriate device. In a fire or if heated, a pressure increase will occur, and the container may burst, with the risk of a subsequent explosion. Remove ignition sources. Isolate from fire, if possible, without unnecessary risk. Stop leak if safe to do so. Proper grounding procedures to avoid static electricity should be followed. Prevent from entering sewers, basements and workpits, or any place where its accumulation can be dangerous. For non-emergency personnel Protective equipment Wear self-contained breathing apparatus and protective suit (see section 8). Emergency procedures Evacuate the danger area. If outdoors, move to an area upwind of the danger area. If possible without taking personal risks, remove ignition sources, ventilate area. Do not breathe gas. Do not get in eyes, on skin, or on clothing. No open flames, no sparks, and no smoking. Prevent other non-emergency personnel from entering the danger area. US - en 3/11 For emergency responders Protective equipment Do not attempt to take action without suitable protective equipment. Total impervious protective suits, gloves, and boots must be worn to prevent any contact with the product. Use self- contained breathing apparatus. For further information refer to section 8: "Exposure controls/personal protection". Emergency procedures Evacuate personnel to a safe area. Monitor concentration of released product. Wear self- contained breathing apparatus when entering area unless atmosphere is proved to be safe. Stop leak if safe to do so. Ventilate spillage area. Use water spray to disperse the vapors. Do not direct water at source of leak or at safety devices as freezing could occur. Prevent from entering sewers, basements and workpits, or any place where its accumulation can be dangerous. Environmental precautions Avoid release to the environment. 6.2. Methods and materials for containment and cleaning up For containment Stop leak, if possible without risk. If the leak cannot be stopped, allow the gas to release in place or remove to a safe, well-ventilated area and allow the release. Leave the product to evaporate. Methods for cleaning up Take up liquid spill into absorbent material. Do not touch or walk on the spilled product. Clean contaminated surfaces with an excess of water. Avoid the spillage or runoff entering drains, sewers or watercourses. For further information refer to section 8: "Exposure controls/personal protection",For further information refer to section 13 7.1. Precautions for safe handling Precautions for safe handling Do not handle until all safety precautions have been read and understood. Use only outdoors or in a well-ventilated area. Wear personal protective equipment. Do not breathe gas. Do not get in eyes, on skin, or on clothing. Use only properly specified equipment which is suitable for this product, its supply pressure and temperature. Take precautionary measures against static discharge. Pressurized container. Only experienced and properly instructed persons should handle gases under pressure. Technical measures Oxygen detectors should be used when asphyxiating gases may be released. Hygiene measures Do not eat, drink or smoke when using this product. Always wash hands after handling the product. Contaminated work clothing should not be allowed out of the workplace. Additional hazards when processed The gas is heavier than air. 7.2. Conditions for safe storage, including incompatibilities Storage conditions Keep container tightly closed. Always keep container in upright position. Container valve guards or caps should be in place. Store in a well-ventilated place.
