I am working on a project to relocate an existing business to a new location.
THis business deals with storage and dispensing Gases/liquid gases.
They will have Exterior flammable gas cylinder storage bunker locations to store.
ACETYLENE
ETHANE
PROPANE
HYDROGEN
METHANE
PROPYLENE
Question #1) How would you classify the bunker area and surrounding area?
There will be 4 tanks outside next to exterior concrete wall which 3 of 4 tanks are vertival storage tanks.
Tank #1: 141 gal. (CC2) Refrigerated Liquid Carbon Dioxide.
Tank #2: 6K gal. vertical (AR) Liquid Argon.
Tank #3: 6K gal. vertical (O2) Liquid Oxygen.
Tank #4: 11K gal. vertical (N2) Liquid Nitrogen
Question #2) What would you classify the tank area and surrounding?
The 4 tanks as mentioned above will have piping run into the building in the area called Production/Lab (classified as H-3 Occupancy by Architect). There will be 4 different area for each gases where they will transfer the gas through pipes into smaller cylinders. I call that dispensing, so,
Question #3) What would you classify the production/lab area and surrounding?
The other day I went to their existing facility for a walk through and they have a similar set up as will be in the new location, however all existing electrical equipments, enclosures, and so on
are N-3R around the tanks out side, and N-1 inside of bldg.
There was a 800A 277/480V main service with N-3R and a 225A step down transformer with N-3R within 20 ft from the first tank.
Outside there are pump motors, start/stop, Em. shutoff sw, control panels for each tank, all with N-3R enclosures.
Inside the bldg. they hunged some 400W M.H. high bay fixtures with open reflector(standard warehouse type) for lighting. also there are start/stop, emergency shutoff switch, control panel, and a pump motor for each type of gas inside of bldg. all N-1 enclosures.
I did not see any explosion proof enclosures of any kind, so please post your opinions here and tell me what you think. so do you think there is no need for any explosion proof at all?
Your help is much appreciated in advance.
I will try to attach pictures from existing location if I can.
