The Real Club Náutico Calpe (RCNC) have advised that, in Spain, the seller of flares is responsible for safely disposing of them but most of them do not do it because the Spanish legislation is not very clear. However, there are some marinas and clubs that provide this service.
The Salvamiento Maritimo advise that the purchaser of the product at the time of expiration date is responsible for ensuring that the supplier of the flares (manufacturer, importer or distributor) collects the expired products from the end consumer for correct disposal. They also state that the provisions of Annex V of the International Convention for the Prevention of Pollution from Ships (Marpol Convention) must be followed.
Most boat owners I know set off their out of date flares at midnight on New Years Eve, they add to the festive occasion and a good and safe way of disposing of them
But maybe not so safe when the flares are 8 – 12 years out-of-date?
