So if you see that you vis'd a customers cylinder on August 25th of 2015 you would not give him credit for that month the next year?Totally the discretion of the business filling the tank. We consider the viz (and hydro) good through the last day of the month prior to the inspection. For example, if you have an August -15 viz sticker, we'd fill the cylinder through July 31, 2016. Again - totally up to who fills it. Their compressor - their rules.
Using that logic they end up, over time, getting screwed.
Because now if he comes in on Aug 1st he won't get a fill without a new vis which technically, according to your policy, should have been done prior so that a July sticker would now get put on.
Making the following year June. No win situation here.
The sticker should be good for one full year. 365 days. I know most don't have a month/date/year option to punch but maybe they should?
IMO sticker is good until the last day of the month it was punched.
The truth though is that it is only good for the 1st fill after vis. Once it's emptied and refilled the filler has no idea what is in it. Industry racket that we need to deal with.
