Electrical fires are more common
MH diesel fuel/oil leaks...seized bearings are also sources of fires
I agree about risk. For there is more risk retiring to a recliner and boob tube. There may come a time when I can not longer safely enjoy the MH or sailboat.
For any who do not like my safety rants, now would be a good time to stop reading. If I am trapped in a fire, I am not worried about what the chemical to put out the fire might do to the ozone layer.
I listen to a podcast about fatal engineering blunders. It has a segment called ‘safety third’ where listeners share blunders.
So why is a flammable refrigerant being used?
“HFC-free fridges use a refrigerant, R-600a or isobutane. R-600a has a very low global warming potential (GWP) of 3 compared with R-134a, the typical HFC used in fridges, which has a GWP around 1,400! R-600a is also very energy efficient, reducing your electric bill and even more emissions.”
Safety third? The EPA building is next to the White House. Forty years of observing the EPA tells what is number one. The environment, science, and safety do not make the top five.
In other words, do not make one thing worse while failing to make the other better.
Think I am wrong! While achieving ‘good air quality’ in the US, the unintended consequence is indoor air pollution and messing up ground water.
Safety comes first. The OSHA warning label says there is a safety risk. The science says that there is marginal if any benefit for the environment with flammable refrigerant.
