Section 4: Personal Protective Equipment All work in laboratories must be performed under the guidelines for appropriate laboratory attire, as defined by the MSU Chemical Hygiene Plan: Close-toe shoes Long pants or long skirt covering the legs from the waist to the top of shoes Safety glasses or goggles, as appropriate In addition, flame resistant (FR) lab coats must be worn when working with flammable materials, including flammable gas. State where PPE for this procedure can be found in the laboratory Section 5: Engineering Controls Describe engineering controls that will be used to prevent explosions and fires such as flame arrestors, restricted flow orifices, intrinsically safe regulators, gas cabinets(if necessary) Please note: Flammable gases must be kept 20ft or more away from oxidizing gases/oxygen cylinders. Pyrophoric gases (such as silane) have specialized equipment requirements. Please contact Genevieve Cottrell at 432-8715 for more information Acetylene gas has unique properties, requiring specialized equipment. to the Acetylene SOP for more information. Mixing of flammable gases and oxygen in secondary containers or in processes is prohibited Section 6: Special Handling and Storage Requirements Describe how the gas cylinder will be secured Describe how the experimental apparatus will be tested with an inert, non-toxic gas (“dry-run”) before attaching the flammable gas cylinder, if appropriate Describe how the system will be tested for leaks, and the preventive maintenance schedule for leak testing Typical leak points are the packing nut, the threads, the collar, the pressure relief device, the regulator, and other attachments. If a leak is found, tighten the connection from which acetylene is leaking. Remember that the regulator connection is a left-handed thread and must be turned to the left to be tightened List anticipated purchase amounts, and maximum amounts of flammable gas expected to be in the laboratory at any time. Note: The maximum allowable aggregate quantity of flammable gas in a laboratory is 1000ft3. Please contact Genevieve Cottrell at 432-8715 if quantities larger than 1000ft3 are necessary
