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
•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 necessary pressure. This will allow for quicker shutoff in the event of a failure or emergency.
3.4 Safety Equipment:
•RFO (Restrictive Flow Orifice) shall be installed in the gas cylinder for the max flow required. •Portable gas detectors (LEL meter) shall be placed in each experiment.
3.5 Cylinder Exchange/Relocation/Acceptance:
The lab manager is the ONLY lab user authorized to exchange cylinders, relocate or move cylinders and complete inspection acceptance upon delivery.
4. Emergency Response Plan
4.1 Minor Gas Leaks:
•Immediately, turn off any ignition source notifying others in the same area. Ignition sources include open flames and sparks, sources of heat and ungrounded or non-intrinsically safe electrical or electronic equipment. •Turn off a main valve of the gas cylinder.
•Place an exhaust hood just above the gas cylinder for ventilation. •Turn off all electrical equipment by following appropriate shut down procedures for each. •Verify suspected leaks using a flammable gas detector or soapy water solution (a flame should not be used for detection). •If possible, repair the leaking part by being consulted with LSR. If the leak cannot be stopped by tightening a valve gland or packing nut, emergency action procedures should be initiated by calling 911. •Report to LSR and PI.
4.2 Major Gas Leaks:
•Immediately call 911 from mobile phone and report the incident. •Sound the alarm by pulling the nearest fire alarm pull station or warn others by verbal means. The pull station(s) closest to our laboratory are located:
On left side of exit door
•Evacuate the area, securing entrances and providing assistance to others on the way out. •Provide emergency response officials with details of the problem upon their arrival. The UNIV. Fire Department will respond to gas emergencies.
University policy is such that individuals are not required to fight fires, but that those who choose to do so may fight small, incipient...
