Re: Refrigeration perils
That is why it is called OFN it is short for your last three words.
Oh F*** No

Re: Refrigeration perils
In any poor ventilated area any gas can be a hazard.
The most common is pub cellars but in most cases bar staff are not warned of the hazards.
In pub cellars CO2 & Nitrogen are used to dispense beer and any leaks can soon build up and deplete the oxygen levels.
This is the most common place for this type of accident to happen.

Re: Refrigeration perils
Nitrogen makes up 80{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the atmosphre at sea level so we are inhaling it all the time,hen it reaches 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} then it’s curtains!with oxygen at less than 17{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} before inhalation in the atmosphere it;s the main atmospheric gas.
When using oxygen free nitrogen for pressure testing or when brazing refigeration systems it can be vented without restriction.
High concentration of gas in any form is hazardous.Re: Refrigeration perils
A lot of fuss over nothing but a good case for better training.
So many have very little training and are let lose on fridge system repair. the first time I had any training on compressor changing was half a day, not a word about gas and it’s hazards.
What ever gas you are working with, only do it with good ventilation. Even today there is no requirment to be qualified to work on R600a yet it is explosive in the wrong conditions. Yet we all have to jump through hoops to work with R134. Who’s crazy idea was it to use buthane in fridges anyway!The article said the gas was used by vets to put animals to sleep. My daughter is a vet she said they use carbon monoxide to kill male chicks in battery farms but has never known OFN being used in any Veterinary application. OFN could not kill in 5 seconds even at 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} it would take 60-90 seconds to take effect death would take a bit longer. :rolls:
