the numbers near the grommets w here the cell is attached

to the container. If the CO2 inspection has been performed,

add "CO2 INSP."

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

inspect them.

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.
