Used Fireworks: Soak used fireworks in a bucket of water for at least 15 minutes until they are cooled down. Wrap the used fireworks in a plastic bag and put the bag in your garbage. Pour the remaining water into a grassy area to prevent the toxic metals contained in fireworks from entering a storm drain.
Unused Fireworks: Contact the WA State Patrol to dispose of unused fireworks.
