7. HANDLING AND STORAGE
Only trained personnel should handle or use containers. Do not subject containers to excessive heat or mechanical shock. Where possible, containers should be out of doors or in a well-ventilated place. Obey all inhouse and statutory regulations. If more than one gas or mixture is kept, ensure that they can be readily identified and separated if necessary. Use only equipment suitable for the gas(es), temperature and pressure involved and inspect regularly. Do not remove labels from containers. Do not handle containers by the valves. Do not use oil or grease on valves, fittings, or any other equipment. Always close valves using moderate force only, even when the container is empty. Containers should be kept upright even when empty.
