Methods and materials for containment and cleaning up Avoid dispersal of dust in the air (e . g. clearing dust surfaces with compressed air) . Clean-up spills immediately using non-sparking utensils . Wet down spilled materials prior to initiating clean-up and keep material wet until ready for disposal . Avoid contamination of water bodies during clean up and disposal . This material is heavier than water. Create an overflow dam with filtration capabilities to retain material . Collect dust using a vacuum cleaner equipped with HEPA filter. Large Spills : Sweep, shovel or vacuum up spillage and collect in suitable container for disposal . For a spillage into water: where possible, remove any intact containers from the water. Clean contaminated surfaces thoroughly to remove residual contamination . Never return spilled material to original containers for re -use . For waste disposal , see section 13 of this SDS . Section 7 - HANDLING AND STORAGE Precautions for Safe HandlinE Do not handle until all safety precautions have been read and understood . Do not subject to mechanical shock . Avoid exposure to sunlight or artificial ultraviolet light. Minimize dust generation and accumulation . Provide appropriate exhaust ventilation . Avoid breathing dust . Avoid contact with eyes , skin and clothing . Do not taste or swallow. Wear appropriate personal protective equipment. Observe good industrial hygiene practices . Smokeless powder contains stabilizers and deteriorates very slowly under proper storage conditions . Old smokeless powder should be checked for deterioration regularly . Deteriorating smokeless powder produces an acidic odor and may produce reddish -brown fumes . Dispose of deteriorating smokeless powder through , for example, controlled open burning in small quantities (products should be submerged in water until burned) . Smokeless powder should not be exposed to excessive heat, as this can accelerate deterioration . Deterioration produces an acidity that accelerates further reaction and has been known, because of heat generated by the reaction, to cause spontaneous combustion . Conditions for safe storage, including any incompatibilities Store at 21 ° C (70°F) , 50% relative humidity (decomposition becomes measurable above 50°C ( 122 °F) . Store in original container. Keep container tightly closed . Store in a cool , dry, well -ventilated place away from all sources of ignition . Store away from incompatible materials (see Section 10 of this SDS) . For additional information regarding handling and storage guidelines , see "Properties and Storage of Smokeless Powder" published by the SPORTING ARMS AND AMMUNITION MANUFACTURERS INSTITUTE, INC ( SAAMI) , 11 Mile High Road, Newtown , CT 06405 (www . saami . org) Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION Control Parameters Occupation Exposure Limits OEL Chemical Name CAS Number ACGIH TLV OSHA PEL Other Information Nitrocellulose 9004-70-0 None established None established Nitroglycerin 55-63 -0 0.05 ppm Skin 0.2 ppm 2.0 mg/m3 Air sampling alone is insufficient Designation OSHA limit applies to skin to accurately quantify exposure.
