No, the EPA cannot go after you for venting this substance. The EPA has scantioned this substance to be dispersed into the atmosphere. But they could take your license fir venting a known. Hfc.
152-A main component is Ethane and I would be more concerned with an contacting an open flame than ODP(which is zero). Google it and read the warnings
1,1-Difluoroethane is an organofluorine compound with the chemical formula C2H4F2. This colorless gas is used as a refrigerant, where it is often listed as R-152a or HFC-152a. As an alternative to chlorofluorocarbons, it has an ozone depletion potential of zero, a lower global warming potential (120) and a shorter atmospheric lifetime (1.4 years). It has recently been approved for use in automobile applications as an alternative to R-134a.

 Production1,1-Difluoroethane is produced by the mercury-catalyzed addition of hydrogen fluoride to acetylene:
HCCH + 2 HF → CH3CHF2
The intermediate in this process is vinyl fluoride, the monomeric percursor to polyvinyl fluoride.
 UsesIn addition to serving as a refrigerant, 1,1-difluoroethane is also commonly used in gas duster (commonly thought of as "canned air"), and many consumer aerosol products, especially those subject to stringent VOC requirements.
 SafetyThe practice of huffing canned air can be extremely dangerous or fatal. The intentional inhalation of 1,1-difluoroethane caused a fatal cardiac arrhythmia in a 42 year-old man. Several reports of fatal car crashes have been linked to drivers huffing 1,1-difluoroethane.
In a Du Pont study, rats were exposed to up to 25,000ppm (67,485 mg/m3) for six hours daily, five days a week for two years. This has become the NOAEL for this substance. Prolonged exposure to difluoroethane has been linked in humans to the development of coronary heart-disease and angina.
I think the difference is that in the canned air it is considered a deminimus vent, seeing as how it is only a few ounces. If you were to vent from a refrigeration system, that would not be deminimus. Goes along the same lines as oil. New refer oil is not hazourdous waste, until it is mixed with refrigerant
In the can it is a propellant. In the refer system it is a refrigerant. The law says not to vent refrigerant.
The sale and use of nitrous oxide is controlled, unless it is a propellant in whipped cream (you know you tried it in high school).
Vanilla extract and hair spray are about 80 proof and a child can purchace them. Light beer is something like 3% alcohol but you have to be 21.
It's all politics and money - nothing new.
LOL! I'm dusting off my keyboard right now with a refrigerant hose and a drum of.
That's it! I'm never huffing again, especially if it's going to give me heart disease or a vagina.

As the hospital I worked for was quite concerned that they would no longer be able to use their gas sterilizers after the rules went into effect, we researched the impact of the law. Basically if it's used as a refrigerant then the no venting rules apply. If not then any product that uses it has to display a label saying this product was produced using chemicals that harm the ozone layer, or something to that effect. So by that interpretation once you put it into a refrigeration/AC system you are not allowed to vent it without recovering it.

We took it with a grain of salt because we were so enthused about becoming certified and felt a sort of satisfaction of achievement by getting the license. But now we realize how stupid regulation is.
