Now I wear eye and ear protection during test. Also noticed they have quality issues with valve cores not being tighten properly.
Gotta protect the ears... at work a few months ago I was filling a dewar with liquid nitrogen, and the only PPE I opted for was earmuffs (not required.) My manager happened to come outside and came up behind me and put a face shield on me and handed me the cryo gloves (very much required.) was kind of funny.
