Store flares, with plastic cap and removable lid in place, in the original cardboard box or a container that has a secure lid. Avoid storing flares oriented so that the ignition button and striker ends could face each other. If using an storage tray, place the flares in a compartment separate from any other items.

Can you keep flares in a hot car?

Storing Road Flares in Vehicles

Road flares should never be stored in a car or truck glove box due to heat. Always store the flares with the plastic cap and removeable lid firmly in place. Use the original cardboard container or box with a secure lid.

How long do flares last in storage?

Flares expire after 42 months and must be replaced to meet the USCG's carriage requirements. Simply throwing expired flares in the trash would be an environmental and health hazard as they contain highly toxic chemicals such as perchlorate.
