Don’t Convert to R134a

I just have one question. Do you ever plan to buy a refrigerator made after 2022? Or eat in restaurant with a walk in cooler?
I’m only asking because r600 and r290 are propane and butane based refrigerants.. (everything is moving to this for environmental reasons)
and these are used in applications where open flame burners and vats of boiling oil are commonly placed in close proximity to them. Food for thought from a dumb guy..

They do contain ignition suppressants or flame retardant compounds. Even commercial refrigerators do not contain high volumes of refrigerant. A leak that could cause an increase in a fire would involve a large line rupture, but result in a quick flash and be done.
With the flame retardant in the automotive recharge refrigerant and the low volume installed, the concern over fire is negligeble. My concern would be service while on a holiday when say the compressor fails. Shops may refuse non automotive refrigerant repairs, as it contaminates the recycle bottle. If they do work on it, they may charge a healthy surcharge.
