ethylene glycol versus propylene glycol
(OP)
Is anyone aware of the need to provide containment for 50/50 EG systems? I would rather not use PG.

RE: ethylene glycol versus propylene glycol
PG is considered to be environmentally safe.

RE: ethylene glycol versus propylene glycol
Propylene glycols are most commonly used in applications in which low acute oral toxicity is required, or for freeze protection where incidental contact with drinking water is possible. In some areas, use of propylene glycols is required by local regulation. Propylene glycol-based fluids are used extensively in food processing applications, but ethylene glycol-based fluids can also be used in some instances
RE: ethylene glycol versus propylene glycol
Containment isn't a huge issue (unless you're running it over food preparation areas).
RE: ethylene glycol versus propylene glycol
I have always used 50/50 EG and water for engine cooling water systems. I was caught a little off guard when someone asked if the radiators needed to have a containment basin. I have never seen one around a radiator. It only holds about 100 gallons and the entire system only holds about 300 gallons. I believe the reporting requirement for a spill is 5000 pounds, which would be 550 gallons. In addition, it is unclear to me if that is for pure EG or mixtures of EG and water.
