Yes, it's such consideration that EPA requires each manufacturer to specify
a unique background color for the label which they require to be applied,
and specifies what information has to go on the label.

And Freeze 12 and Hot Shot and Chill It and every other refrigerant
approved for use in automobile AC systems.  Here are the currently
available specs as published by the American EPA on their website.
http://www.epa.gov/ozone/snap/refrigerants/fittlist.html  It also gives the
required label colors.  Kindly note that no flammable mixture has been
approved http://www.epa.gov/ozone/snap/refrigerants/macssubs.html and the
reason given for certain specific disapprovals (HC-12a for example) is
flammability.

>Good Evening,

Indeed...do say hi to Terry for me if you happen to see him.  Perhaps he
might be able to assist you with making your way through the EPA material
-- it's a big website with many words on it, no doubt some of them apply to
this situation.
