I have recently been tasked with creating a cylinder management plan for hydrogen sulfide for a lab currently under construction. This is a bit out of my comfort zone, hence my post. Here is the information I have so far:
1. We are looking at most likely a 3-10L bottle.
2. The lab will contain vented gas cabinets and hydrogen sulfide continuous monitoring systems
3. Personal monitors will be worn by all personnel
I am specifically trying to but together an internal movement SOP that includes the following:
1. Transport from the loading dock via a series of underground corridors to a freight elevator
2. Movement from the basement to the third floor in the elevator (I assume that the cylinder cart should be placed on the elevator, appropriate floor pressed, and a second person will meet the cylinder at the top - this would also require "proctors" placed in the middle floors to keep people from getting on)
3. Disconnection of "in-use" cylinder from the regulator within the gas cabinet (should the cylinder be ran to virtually empty, or should a bit of pressure be left within the cylinder)?
4. Connection of full cylinder
5. Transport of "empty" cylinder to the dock for pickup in reverse of step 2
Obviously the above can be done in reverse with the "empty" cylinder being taken down followed by the full cylinder coming back up. What PPE concerns should I have for transport and are there specific regulation that point towards transportation via occupied spaces for H2S?
