Lifejacket maintenance for automatic lifejackets

Typical inspection points include: shell (tears, abrasion, seams), harness and fasteners, activation unit (e.g., automatic release), CO₂ cartridge (fit, corrosion, weight/status depending on the system), bladder (condition), leak/pressure test, mouth valve, and, if applicable, accessories such as emergency light, sprayhood, crotch strap, and mounting options for PLB/AIS. Wear parts/seals are replaced as needed, after which the jacket is properly packed and the maintenance documented (sticker/certificate).

For recreational use, servicing every 2 years at the latest is a sensible standard—or sooner, depending on the manufacturer’s specifications and usage. For intensive use or professional applications (e.g., company regulations, charter operations, occupational safety association/company guidelines), annual servicing is often standard practice or required. The manufacturer’s specifications and actual conditions of use (humidity, UV exposure, saltwater, storage duration) are always decisive.

If any of the following apply, the vest should be inspected promptly: Corrosion on the cartridge/mechanism, damaged cover, Velcro does not close reliably, webbing frayed, status indicator on the trigger shows “not OK,” vest was in the water/has deployed, significant UV/heat exposure (e.g., left in the cockpit for a long time), or the vest was stored while very damp. It’s also worth getting it checked after a fall or impact, or if the vest feels “off.”

Maintenance is usually worth it if the cover, straps, and bladder are in good condition and it’s “only” about consumable parts (release mechanism/cartridge/seals). A new purchase may make sense if load-bearing parts are damaged, the life jacket is very old, replacement parts are hard to find, or if you want to switch to different equipment (e.g., harness, sprayhood, AIS/PLB integration). We’re happy to help you assess the situation.

After contact with salt or splash water: rinse with fresh water, then let it dry completely and store in a well-ventilated, dry place protected from UV light. Avoid prolonged exposure to heat (heating, direct sunlight) and do not “squeeze” anything that puts strain on the Velcro or bladder. Perform a brief visual inspection regularly: cover, harness, activator status indicator, and cartridge seat.

Some systems allow the user to replace the trigger/cartridge—provided the exact correct kit is used and installation is performed according to the manufacturer’s instructions. For maximum safety (and depending on commercial sector requirements), however, professional maintenance—including leak and pressure testing and documented inspection—is the most reliable solution.
