Authorities are concerned with the number of aged flares being handed-in, as part of a mobile-collection program.
The average flare has a use-by date of three years, but when corroded, they can emit toxic fumes.
Over the last two days, local volunteers have collected more than 600 expired items.
Another drop-off point will be held at Blacksmiths Boat Ramp tomorrow.
