RV Fridge Coolant solution:
Ammonia, Hydrogen Gas, Water, Sodium Chromate under 300 psi.
Leak in cooling unit:
hydrogen gas Psssfff---gone (quantity very small & very limited fire source)
ammonia Pssssffffff---gone except for lingering smell
water still in tubing above leak
sodium chromate still in water solution except for amount that got sprayed out of leak (it's the yellow residue---anti-rust inhibitor)
Atwood has a Helium Fridge.......swapped hydrogen for helium. Rest of ingredients same.
