All, I have worked my entire career in industry but was educated in a univers ity and continued to take classes and conduct research at a local univer sity and comment as such. During my first job I was involved in the des ign of a new QA/QC/environmental laboratory. All of our gasses, includi ng possible future gasses, were placed remotely and piped into the lab t o all potential use locations. Oxidizers and fuels were separated into separate compartments. 1. Yes, we (some) are ignorant of cylinder safety and hazards. I receiv ed my cylinder safety training in my SCUBA diving certification classes as a freshman in the late 60's. I received additional training in my up per level instrumentation classes though the training was not "formal" a s known today. I received additional training during the welding classe s I took at the local community college. 2. SAFETY Education (including cylinder and high pressure gas use) is a must and should begin before anyone is allowed in a laboratory. But, th is education must start a the TOP. ALL PROFESSORS, DEPARTMENT CHAIRS, S TOREROOM PERSONNEL, AND LAB MANAGERS must be educated and tested first!! !! Professors are responsible for their graduate and undergraduate stud ents. 3. The various parts of a fume hood (including the airfoil) (or any equ ipment) were designed and put on the equipment for a reason - they shoul d not be removed!!! DOES ANYONE KNOW WHAT THE GAS VALVES AND BARBS IN A HOOD ARE FOR???? Try using the equipment!! If there are no gas valves INSTALL SOME!!! 4. Remember, oxidizer and fuel gases (or potential fuels) must be kept at least 50 feet apart according to the OSHA regulations. No One has me ntioned this in all the e-mails. 5. I tell my company's facility managers that the first day a new hire is on the job he is no good for production - the entire day should be us ed for indoctrination including reviewing all safety rules and touring t he facility pointing out various safety issues and equipment. This shou ld be the same for all laboratory classes - the first lab session is dev oted to nothing but safety, including lecture, demonstrations, videos, a nd quizzes. On one has mentioned the use of cyrogenic gas safety. ________________________________________________________________________ Try Juno Platinum for Free! Then, only $9.95/month!
