(LAB)
1. Description
In initial operating period of LAB,. This plan deals with a safety concerning temporary use of gas cylinders inside the lab area.
2. General rules
Everyone in the lab is responsible for working in accordance with the guidelines and safe practices outlined in the “Safety Plan for the Combustion - LAB” and the UNIV. Lab Safety Manual even if some matters are not mentioned or included in this document.
3. Gas Cylinder handling and use
3.1 Identification:
• The contents of any compressed gas cylinder shall be clearly identified.
• Such identification should be stenciled or stamped on the cylinder or a label.
• Empty cylinders shall be labeled with the word empty or the abbreviation MT.
3.2 Securing Bottles:
• All gas cylinders shall be properly secured to a workbench with appropriate belts (or chains) in an upright position above the midpoint, but below the shoulder at all times.
• Cylinders should NEVER be left free standing.
• All cylinders shall be capped when not in use or attached to a system.
• Especially, oxygen gas cylinders shall be kept at least 20 ft. (6 m) away from all flammable, combustible substances.
• If a cylinder falls over, no one should EVER attempt to catch it. Competent help should be called to assist in setting it upright.
3.3 Regulator & Valves:
• Installation and removal of regulators will be completed by qualified individuals.
• Ensure that regulator pressure control valve is relieved (i.e., closed) before attaching to tanks.
• Close valves on gas cylinders when a system is not in use.
• Remove all pressure from regulators not currently used (by opening equipment valves downstream after the regulators are closed).
• Cylinder valves should be opened slowly
• Valve outlets and regulators should be pointed away from all personnel when cylinder valves are opened.
• Valves should only be opened to the point where gas can flow into the system at the
