No part of cylinder should be subjected to a temperature higher than 125°F <br /> (520C). Carbon dioxide cylinders are typically equipped with a pressure relief device. <br /> (Exceptions may exist where authorized by DOT.) <br /> 6. Accidental Release Measures <br /> STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: <br /> WARNINGI High-pressure liquid and gae. Rapid release of gaseous carbon dioxide <br /> through a pressure relief device (PRD) or valve can result In the formation of dry Ice, <br /> which Is very cold and can cause frostbite. <br /> PERSONAL PRECAUTIONS: Carbon dioxide is an asphyxiant. Lack of oxygen can kill. Use <br /> self-contained breathing apparatus where needed. See Section 11. <br /> PERSONAL PROTECTIVE EQUIPMENT(PPE): See Section g, Exposure Control/Personal <br /> Protection. <br /> EMERGENCY PROCEDURES: Evacuate all personnel from danger area. Shut off leak If you <br /> can de so without risk. Ventilate area or move cylinder to a well-ventilated area, Test for <br /> 5ufflotent oxygen, especially in confined spaces, before allowing reentry. <br /> Methods and Materlals for Containment and Cleaning Up: Prevent waste from <br /> contaminating the surrounding environment. Discard any product, residue, disposable <br /> container, or liner In an environmentally acceptable manner, In full compliance with federal, <br /> state, and local regulations. If necessary, call your local supplier for assistance. <br /> 7. Handling and Storage <br /> PRECAUTIONS TO BE TAKEN IN HANDLING: Protect from sunlight. <br /> Avoid breathing gas. Do not get liquid in eyes, on skin, or clothing. Protect cylinders from <br /> damage. Use a suitable hand truck to move cylinders;do not drag, roll, slide, or drop. Never <br /> attempt to Ilft a cylinder by its cap; the cap Is Intended solely to protect the valve. Never Insert <br /> an object(e.g., wrench, screwdriver, pry bar)into cap openings; doing so may damage the <br /> valve and cause a leak. Use an adjustable strap wrench to remove over-tight or rusted caps. <br /> Open valve Slowly. If valve is hard to open, discontinue use and contact your supplier. Keep <br /> cylinder upright when in use. Never apply flame or localized heat directly to any part of the <br /> cylinder, High temperatures may damage the cylinder and could cause the pressure relief <br /> device to fell prematurely, venting the cylinder contents. For other precautions In using carbon <br /> dioxide, see section 16. <br /> PRECAUTIONS TO BE TAKEN IN STORAGE; Store In a well-ventilated place. <br /> Gas can cause rapid suffocation due to oxygen deficiency. Store and use with adequate <br /> ventilation. Store only where temperature will not exceed 125°F (52°C). Carbon dioxide is <br /> heavier than air. It tends to accumulate near the floor of an enclosed space, displacing air and <br /> pushing it upward. This creates an oxygen-deficient atmosphere near the floor or in pits and <br /> trenches. Ventilate space before entry. Verify sufficient oxygen concentration. Close cylinder <br /> valve after each use; keep closed even when amply, Prevent reverse flaw.
