Have you tried to have your professors calculate the explosive power stored in that room and translate it to something relatable to your management, like blast radius.


A few questions… largely out of my ignorance…


Is it prudent to store all of those cylinders in a closed room?


If you have cylinders in a closed room, wouldn’t it be prudent to have gas monitoring in place to alert you if a tank leaks?


Wouldn’t you be required to have ESD shoes to enter such room?


If the AV rack is hardwired to the wall, is it properly grounded?


Thank you,


Yaritza Brinker

Hello all,


Curious to get this group’s input… I recently discovered a large A/V rack in the gas cylinder room of my university’s science building.  The A/V rack is hardwired into the wall, and is NOT spark-proof/hospital grade.  It could make sparks at any time.  In the same room, we have full cylinders of compressed oxygen, nitrous oxide, and air. The room itself likely has flammable construction.  We probably have about 50 employees in the building, plus hundreds of students during the academic terms.


All the science faculty are (rightly) having a conniption fit and demanding that the A/V rack be moved to another room.  However, the city fire chief inspected and said that “cylinders were properly stored and there was no open flame in the room”, so no move was necessary, as no code was violated.  So now the administration is dragging its feet, saying that the rack doesn’t need to be moved (and IT suggested that we should just plug it back in).


Are there resources out there to convince the higher level of Administration that this situation is inherently hazardous and worth the resources to correct?  Besides pedantically explaining the fire triangle/tetrahedron to them and bringing up the Apollo 1 fire?  Or are the entire biology, chemistry, physics and nursing faculty (and I) all over-reacting?


Thanks for your help,


Nora Dunkel
