g. At least once a year, from preservers undergoing
inspection, inflate random samples with CO2 to insure
proper functioning of the CO2 inflation system. Do not
inflate more than 5 percent of the total number of preservers
being inspected. If any sample preserver fails the CO
inflation inspection, inflate all the preservers with CO2 and
h. Deflate the preservers that have been CO inflated,
and leakage-test them as outlined in e above. When
performing the CO2, inflation tests, check the inspection
dates to make sure the preservers undergoing CO inflation
testing have not been CO2 inflated within one year.
