This safety alert reminds all inflatable life jacket users of the importance of performing periodic maintenance on their equipment. Instances of fatal accidents where inflatable life jackets failed to properly inflate have been documented. When a life jacket fails to inflate properly, the results can be life-threatening. Unknown bladder leaks may exist, fabric degradation or an improperly installed CO2 cylinder is all it takes to render an inflatable life jacket ineffective by preventing its inflation or ability to stay inflated.
Various manufacturers of inflatable equipment will likely have different maintenance instructions for their products and directions for the user to service and inspect the devices. Knowing and following the manufacturer’s maintenance instructions are critical. Proper maintenance service and inspection will ensure all parts of the life jacket including the bladder, inflation mechanism, and CO2 cylinder are checked and in good working order.The Coast Guard highly recommends routine maintenance, service, and inspection in accordance with the manufacturer’s instructions. The following inflatable life jacket inspection guidance is for
informational purposes only and does not supersede any manufacturer recommendations or instruction:
1) Each voyage, prior to getting underway:
a. If there is a service indicator check it to ensure it is GREEN. If
the service indicator is RED the mechanism has been fired or is incorrectly
b. Check for visible signs of wear or damage by ensuring that there are no rips, tears or holes; that the seams are securely sewn; and that the fabric, straps and hardware are still strong.
c. For auto-inflating life jackets, ensure all auto components are armed and not expired. Following the manufacturer’s instructions, reveal the inflation system and oral inflation tube. Check that the CO2 cylinder is firmly secured. Examine it for rust or corrosion. If you remove the CO2 cylinder for inspection, be sure to carefully replace it without over-tightening.
d. Repack the lifejacket as per manufacturer’s instructions. Ensure the pull-tab lanyard is accessible and unlikely to be caught when being worn.
2) Periodic checks as recommended by the manufacturer or when in doubt:
a. Inflate the bladder using the oral tube and leave it overnight in a room with a constant temperature. If the bladder loses pressure, take the lifejacket to an authorized service center for further tests. Do not
attempt to repair a life jacket yourself. If there is no obvious loss of pressure, deflate the life jacket by turning the cap of the inflation tube upside down and pressing it into the inflation tube. Gently squeeze the inflatable life jacket until all air has been expelled. To avoid damage do not wring or twist the life jacket.
b. Repack the lifejacket as per manufacturer’s instructions. Ensure the pull-tab lanyard is accessible and unlikely to be inadvertently snagged when being worn.
Store your life jacket in a dry, well-ventilated location away from dampness and out of direct sunlight. It’s important to rinse your life jacket with fresh water after salt water exposure and dry it thoroughly prior to storage. If your life jacket is set for auto-inflation, remove the auto-inflation cartridge prior to rinsing. The life jacket manufacturer may have specific requirements, so read the instructions on the lifejacket.
