eh fridges only have a couple liquid ounces of delicious refridgerant. people bust those lines all the time trying to defrost their freezer with a pick or somethin. i guess it's possible you could be injured seriously :o but i doubt it. buying a new fridge will prolly be the harshest blow. they were still making fridges with r-12 well into the 90s i thought. not that it matters really :o jus musing.
