Description of first aid measures General advice Show this safety data sheet to the doctor in attendance. Inhalation Remove to fresh air and keep comfortable for breathing. If breathing is difficult, give oxygen. If breathing has stopped, give artificial respiration. Get medical attention immediately. Skin contact None under normal use. Get medical attention if symptoms occur. Eye contact None under normal use. Get medical attention if symptoms occur. Ingestion Not an expected route of exposure. Self-protection of the first aider RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS. Most important symptoms and effects. both acute and delayed Symptoms Simple asphyxiant. May cause suffocation by displacing the oxygen the air. Exposure to in oxygen-deficient atmosphere (<19.5%) may cause dizziness, drowsiness, nausea, vomiting, excess salivation, diminished mental alertness, loss of consciousness and death. Exposure to atmospheres containing 8-10% or less oxygen bring about will unconsciousness without warning and so quickly that the individuals cannot help or protect LIND-M0027 CARBON DIOXIDE (2-30%) ARGON in Revision Date: 03-May-2021 themselves. Lack of sufficient oxygen may cause serious injury or death. Depending on concentration and duration of exposure to carbon dioxide may cause increased respirations, headache, mild narcotic effects, increased blood pressure and pulse, and asphyxiation. Symptoms of overexposure become more apparent when atmospheric oxygen decreased to 15-17%. is Indication of any immediate medical attention and special treatment needed Note to physicians Treat symptomatically. Suitable extinguishinq media Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. Specific extinguishing methods Continue to cool fire exposed cylinders until flames are extinguished. Damaged cylinders should be handled only by specialists. Specific hazards arising from the chemical Non-flammable gas. Cylinders may rupture under extreme heat. Protective equipment and precautions for firefiqhters As in any fire, wear self-contained breathing apparatus pressure-demand, NIOSH (approved or equivalent) and full protective gear. Personal precautions. protective equipment and emerqency procedures Personal precautions Evacuate personnel to safe areas. Ensure adequate ventilation, especially in confined areas. Monitor oxygen level. Wear self-contained breathing apparatus when entering area unless atmosphere is proved to be safe. Environmental precautions Prevent spreading of vapors through sewers, ventilation systems and confined areas. Methods and material for containment and cleaninq up Methods for containment Stop the flow of gas or remove cylinder to outdoor location if this can be done without risk. If leak is in container or container valve, contact the appropriate emergency telephone number in Section 1 or call your closest Messer location. Methods for cleaning up Return cylinder to Messer or an authorized distributor. Precautions for safe handling Advice on safe handling Protect cylinders from physical damage; do not drag, roll, slide or drop. Never attempt to lift a cylinder by its valve protection cap. When moving cylinders, even for short distance, use a cart designed to transport cylinders. Never insert an object (e.g. wrench, screwdriver, pry bar.etc.) into valve cap openings. Doing so may damage valve, causing leak to occur. Use an adjustable strap wrench to remove over-tight or rusted caps. If user experiences any difficulty operating cylinder valve discontinue use and contact supplier. Use only with adequate ventilation. Use only with equipment rated for cylinder pressure. Use a backflow preventive device in piping. Close valve after each use and when empty. Ensure the complete gas system has been checked for leaks before use. LIND-M0027 CARBON DIOXIDE (2-30%) in ARGON Revision Date: 03-May-2021 Never put cylinders into trunks of cars or unventilated areas of passenger vehicles. Never attempt to refill a compressed gas cylinder without the owner's written consent. Never strike an arc on a compressed gas cylinder or make a cylinder a part of an electrical circuit. Only experienced and properly instructed persons should handle gases under pressure. Always store and handle compressed gas cylinders in accordance with Compressed Gas Association publication CGA-P1, Safe Handling of Compressed Gases in Containers. For additional recommendations consult CGA P-76. Conditions for safe storaqe. includinq any incompatibilities StorageConditions Store in cool, dry, well-ventilated area of non-combustible construction away from heavily trafficked areas and emergency exits. Cylinders should be stored upright with valve protection cap in place and firmly secured to prevent falling. Keep at temperatures below 52ºC / 125ºF. Full and empty cylinders should be segregrated. Use a "first in-first out" inventory system to prevent full cylinders from being stored for excessive periods of time. Stored containers should be periodically checked for general condition and leakage. Incompatiblematerials Carbon dioxide is incompatible with:.

LIND-M0027 CARBON DIOXIDE (2-30%) ARGON in Revision Date 03-May-2021 Information on likely routes of exposure Inhalation Acidosis, adrenal cortical exhaustion, and other metabolic stresses have resulted from prolonged continuous exposure to 1-2% carbon dioxide (10,000 ppm-20,000 ppm). The ACGIH TLV of 5,000 ppm is expected to provide a good margin of safety from asphyxiation and undue metabolic stress provided sufficient oxygen levels are maintained in the air. Increased physical activity, duration of exposure, and decreased oxygen content can affect systemic and respiratory effects resulting from exposure to carbon dioxide. Product is a simple asphyxiant.
