When does, or rather SHOULD, a scuba tank VIP expire? Here in the Sandy Eggo there is conflicting shop SOP. I have always been told the expiration of the VIP is on the LAST DAY of the month punched. However a local shop here told me it is the FIRST DAY of the month punched, WTF? If that's true, then there is no way the VIP is actually good for 12months, it's not possible. I politely explained this to one of the shop owners and he yammed on about putting his shop at risk, explosions... yah yah yah. He also stated that if he let the sticker be valid until the end of the month, the VIP would be longer than 12months. Circular reasoning is what I thought as I explained what he was telling me is less than 12months.
While I respect that he has his personal shop's SOP, this guy actually VIP'd the tank last year and has record of the exact date he did so. He refused to understand my position that he has given me less than 12 months on this sticker. I have had heavy owner ego from this particular shop in the past and won't give them my busines in the future but wonder from the VDH forum's POV what the rest of the scuba industry follows: end of month expiration OR first day of month expiration. I'm familiar with DOT regs which of course there is none for VIPs.
