0.0015-23.5%Oxygen;0.0005%-2.5%Methane;0.0005—1.0%Carbon Monoxide;0.001—0.025%Hydrogen Sulfide;Nitrogen Gas balance <br /> Skin . In case of contact, immediately flush with plenty of water for at least 15 minutes. Take <br /> off contaminated clothing. If irritation develops and persists, get medical attention. <br /> Eye . IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, <br /> if present and easy to do. Continue rinsing. If eye irritation persists: Get medical <br /> advice/attention. <br /> Ingestion . Ingestion is not considered a potential route of exposure. <br /> 4.2 Most important symptoms and effects, both acute and delayed <br /> . Refer to Section 11 - Toxicological Information. <br /> 4.3 Indication of any immediate medical attention and special treatment needed <br /> Notes to Physician . Treat symptoms and eliminate over-exposure. Hyperbaric oxygen is the most efficient <br /> antidote to Carbon Monoxide poisoning, the optimum range being 2-2.5 atm. A special <br /> mask, or, preferably, a compression chamber to utilize oxygen at these pressures is <br /> required. Avoid administering stimulant drugs. Be observant for initial signs of <br /> pulmonary edema in the event of severe inhalation over-exposures. <br /> 4.4 Other information <br /> . RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO <br /> THIS GAS MIXTURE WITHOUT ADEQUATE PERSONAL PROTECTIVE <br /> EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus must be worn. <br /> Victim(s) who experience any adverse effect after over-exposure to this gas mixture <br /> must be taken for medical attention. Rescuers should be taken for medical attention if <br /> necessary. Take a copy of the label and the MSDS to physician or other health <br /> professional with victim(s). <br /> Section 5 - Firefighting Measures <br /> 5.1 Extinguishing media <br /> Suitable Extinguishing Media . Non-flammable gas mixture. Use extinguishing media appropriate for surrounding fire. <br /> Unsuitable Extinguishing . No data available <br /> Media <br /> 5.2 Special hazards arising from the substance or mixture <br /> Unusual Fire and Explosion . This gas mixture contains toxic gases, Hydrogen Sulfide and Carbon Monoxide, and <br /> Hazards presents a health hazard to firefighters. This gas mixture is not flammable; however, <br /> containers, when involved in fire, may rupture or burst in the heat of the fire. <br /> Hazardous Combustion . No data available <br /> Products <br /> 5.3 Advice for firefighters <br /> . Structural firefighters' protective clothing will only provide limited protection. <br /> Wear positive pressure self-contained breathing apparatus (SCBA). <br /> Section 6 -Accidental Release Measures <br /> 6.1 Personal precautions, protective equipment and emergency procedures <br /> Personal Precautions . Wear appropriate personal protective equipment. See section 8 for more information. <br /> Emergency Procedures . Due to the small size and content of the cylinder, an accidental release of this gas <br /> mixture presents significantly less risk of over-exposure to Hydrogen Sulfide and <br /> Carbon Monoxide, the toxic components of this gas mixture, and other safety hazards <br /> related to the remaining components of this gas mixture, than a similar release from a <br /> larger cylinder. In the event of a release in which the atmosphere is unknown, and in <br /> which other chemicals are potentially involved, evacuate immediate area. Such <br /> releases should be responded to by trained personnel using pre-planned procedures. <br /> Proper protective equipment should be used. In case of a leak, clear the affected area, <br /> protect people, and respond with trained personnel. <br /> Preparation Date: 10/August/2012 Format:EU CLP/REACH Language:English(US) <br /> Revision Date: 16/December/2013 Page 5 of 18 OSHA HCS 1994,WHMIS,UN GHS,EU CLP,EU DSD/ <br />
