MATERIAL SAFETY DATA SHEET OXYGEN MSDS 1027 Version 2 PHYSICAL AND CHEMICAL PROPERTIES Appearance Colourless gas. * Do not store cylinders in vehicles – remove them once the destination is reached. Oxidising Properties More oxidising than air. Fire-fighting equipment should be carried. Odour None. Relative Density (gas) Heavier than air Only use vehicles where the load is segregated from the driver’s compartment. Flammability None. Extra regulations apply to vehicles carrying large quantities of dangerous substances. Relative Density (liquid) N/A Symbol/Formula O2 Solubility in Water Slightly insoluble Boiling Point N/A Atomic Mass 39.948 g mol-1 Volume Expansion Ratio (liquid to gas) N/A Critical Temperature -118°C * Cold gas may appear white due to ‘fogging’ of surrounding air. STABILITY & REACTIVITY Possibility of violent reaction with reducing agents or combustible materials. Impregnated clothing may readily be ignited. The gas strongly supports combustion. All pipe work and ancillary equipment should be prepared for Oxygen duty. Contact CryoService for information concerning these, or for other transportation information.

MATERIAL SAFETY DATA SHEET OXYGEN MSDS 1027 Version 2 IDENTIFICATION OF SUBSTANCE/ PREPARATION AND COMPANY Product name Chemical formula Company identification Emergency phone number Oxygen (gas phase) O2 See footer See footer COMPOSITION Product type Components CAS number EEC number Oxygen (gas phase) Substance Nominally 7782-44-7 2319569 99.5% minimum HAZARDS IDENTIFICATION Oxidant gas under high pressure. Skin High-pressure release may cause injury. Eyes High-pressure release may cause injury. Inhalation May have adverse effects (sources differ). ACCIDENTAL RELEASE MEASURES Personal Evacuate area. Wear suitable protective clothing. Wear selfcontained breathing apparatus if it is necessary to enter the area. Environment Close the valve, and/or remove container to the open air if safe to do so. Prevent from entering basements, workpits, sewers and other low lying areas where accumulation could be dangerous. HANDLING AND STORAGE Only trained personnel should handle or use cylinders. Do not subject cylinders to excessive heat, cold or mechanical shock. Store cylinders out of doors or in a well-ventilated place. Prepare and implement a procedure to deal with any emergency. Obey all in-house and statutory regulations. FIRST-AID MEASURES Eye contact Immediately flush eyes thoroughly with tepid water for at least 15 minutes. Obtain medical assistance. Skin contact Immediately flush the affected area with tepid water for at least 15 minutes. Obtain medical assistance. Inhalation Symptoms may include loss of mobility/ consciousness. Using self-contained breathing apparatus, remove casualty from exposure. Call a doctor. Keep casualty warm and rested. If breathing has stopped, apply artificial respiration. FIRE-FIGHTING MEASURES Ensure that the emergency services are aware of the presence of gas cylinders on the premises. If more than one gas or mixture is kept, ensure that they can be readily identified. Use only equipment suitable for the gas(es) and pressure involved and inspect regularly. CryoService Limited offer a range of regulators and fittings. Cylinders without valve guards are shipped in crates;retain these for later use. Do not remove valve guards where fitted. Do not remove labels from cylinders or crates (except the return address cover). Do not lift cylinders by the valve. Use suitable cylinder handling and securing equipment. Do not use oil or grease on valves, fittings, or any other equipment. Always close valves using moderate force only, even when the cylinder is empty. Do not attempt to control the gas flow using the valve. Extinguishing media None required for gas or cylinder. Specific method If there is no risk, close valve and remove container from affected area. Where container cannot be removed, every effort should be made to keep it cool by spraying with large quantities of water from a protected position. Specific hazard Protective equipment Supports combustion. The container may rupture violently if heated. Non-flammable. In confined spaces use self-contained breathing apparatus. Use a suitable regulator. Fit a non-return system if there is any risk of back-flow into the cylinder. Always ensure that the system being pressurised has a suitable outlet. Liquid cylinders (e.g. LPG) should be kept upright Do not transfer this gas into another cylinder by decantation or re-pressurisation. Return empty or unwanted cylinders promptly. EXPOSURE CONTROLS/PERSONAL PROTECTION Be aware of high pressure release. Ensure adequate ventilation. Wear gloves, eye protection and safety footwear when handling cylinders. Keep appropriate safety equipment in the working area.
