Shelf life & disposal.
Shelf life: SOLAS-approved pyrotechnics carry a 3-year expiry from manufacture, stamped on the casing. After that they're no longer compliant — but may still function.
Expired flares: many skippers keep them as backup (separate bag, marked “EXPIRED”) — not a substitute for in-date pyrotechnics.
Disposal: never bin them or throw them overboard. Return expired pyrotechnics to a coastguard station, chandlery, or marina collection point.
