adding wine & beer taps;

the wine system uses nitrogen to keep wine fresh;

the beer system looks to use glycol;

I see in IBC definitions that nitrogen is classified as an inert gas & table 307.1 (1) is N/A or no limit quantity...

however what about glycol for the beer system?

it looks like there will be 3 gallons in the system

Propylene glycol, also called 1,2-propanediol, resembles ethylene glycol in its physical properties. Unlike ethylene glycol, however, propylene glycol is not toxic and is used extensively in foods, cosmetics, and oral hygiene products as a solvent, preservative, and moisture-retaining agent. Propylene glycol is manufactured in large amounts from propylene oxide, which is obtained from propylene.

This is some great info on the stuff.

I take it the glycol is in a closed system????

Do not have the book, but should be no problem

You can ask for the msds for the glycol, to see any hazards

More than likely a class III combustible

Used in chillers all the time as a cooling medium system is not direct expansion there is no change of state from liquid to vapor.

That should say liquid. I know I am working on "sawhorse"

yes it looks to be a closed system.

thx u for the replies all.

Should be a closed system and no issues at all as long as they serve Fat Tire or Elliot Ness on tap
