Fire fighting <br />Allow gas to burn if flow cannot be shut off immediately. Apply water from safe distance to cool <br />equipment/instructions <br />container and protect surrounding area. In case of fire: Stop leak if safe to do so. Do not move <br />cargo or vehicle if cargo has been exposed to heat. ALWAYS stay away from tanks engulfed in <br />flame. Move containers from fire area if you can do so without risk. Do not direct water at source of <br />leak or safety devices as icing may occur. Use water spray to cool unopened containers. Do not <br />get water inside containers. Withdraw immediately in case of rising sound from venting safety <br />device or any discoloration of tanks due to fire. For massive fire in cargo area, use unmanned <br />hose holder or monitor nozzles, if possible. If not, withdraw and let fire burn out. <br />Specific methods <br />Use standard firefighting procedures and consider the hazards of other involved materials. Cool <br />containers exposed to flames with water until well after the fire is out. <br />General fire hazards <br />May intensify fire; oxidizer. <br />6. Accidental release measures <br />Personal precautions, <br />Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Keep out of <br />protective equipment and <br />low areas. Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). <br />emergency procedures <br />Wear appropriate protective equipment and clothing during clean-up. Avoid breathing gas. <br />Emergency personnel need self-contained breathing equipment. Do not touch damaged <br />containers or spilled material unless wearing appropriate protective clothing. Ventilate closed <br />spaces before entering them. Local authorities should be advised if significant spillages cannot be <br />contained. For personal protection, see section 8 of the SIDS. <br />Methods and materials for <br />If this gas leaks without igniting, extreme caution must be used; flammable or explosive mixtures <br />containment and cleaning up <br />with air may be formed. Extinguish all flames in the vicinity. This product is miscible in water. Stop <br />leak if you can do so without risk. Use water spray to reduce vapors or divert vapor cloud drift. <br />Isolate area until aas has dispersed. Dike far ahead of spill for later disposal. Prevent entry into <br />waterways, sewer, basements or confined areas. Following product recovery, flush area with <br />water. For waste disposal, see section 13 of the SIDS. <br />Environmental precautions <br />Avoid release to the environment. Inform appropriate managerial or supervisory personnel of all <br />environmental releases. Prevent further leakage or spillage if safe to do so. Avoid discharge into <br />drains, water courses or onto the ground. Runoff from fire control or dilution water may cause <br />pollution. <br />7. Handling and storage <br />Precautions for safe handling <br />Do not handle, store or open near an open flame, sources of heat or sources of ignition. Protect <br />material from direct sunlight. Keep away from combustible material. Contents under pressure. <br />Keep reduction valves free from grease and oil. Valve protection caps must remain in place unless <br />container is secured with valve outlet piping to use point. Close valve after each use and when <br />container is empty. Do not drop, drag, slide or roll cylinders on their sides. Use a suitable hand <br />truck to move gas containers. Use a pressure reducing regulator when connecting container to <br />piping or systems. Never insert an object (e.g. wrench, screwdriver, pry bar) into cap openings. <br />Use an adjustable strap wrench to remove over -tight or rusted caps. Open valve slowly. Do not <br />use gas directly from containers. Do not heat container by any means to increase the discharge <br />rate of product from the container. <br />Avoid breathing gas. Use only outdoors or in a well -ventilated area. Avoid contact with eyes, skin, <br />and clothing. Wash hands thoroughly after handling. Avoid release to the environment. Observe <br />good industrial hygiene practices. Wear appropriate personal protective equipment. Use personal <br />protection as recommended in Section 8 of the SDS. <br />Conditions for safe storage, <br />Store locked up. Store in a cool, dry place out of direct sunlight. Store in original tightly closed <br />including any incompatibilities <br />container. Store in a well -ventilated place. Store in cool place. Refrigeration recommended. Do not <br />store near combustible materials. Keep away from food, drink and animal feedingstuffs. Store <br />away from incompatible materials (see Section 10 of the SDS). Store in accordance with NFPA <br />430 requirements for Class II oxidizers. <br />8. Exposure controls/personal protection <br />Occupational exposure limits <br />US.
