This would pretty much take care of the problem!Fireworks Law (California)Law Summary
In California, a license is required to sell safe and sane fireworks. However, no permit is required to transport, purchase, or use safe and sane fireworks in the state.
A permit is required to store, possess, sell at wholesale, or discharge dangerous fireworks, which include firecrackers, skyrockets and rockets, Roman candles, chasers, certain sparklers, cigarette loads, trick matches, devil-on-the-walk, and torpedoes. No person may sell dangerous fireworks to any person unless that person presents a permit.
It is illegal to sell, give, or deliver to any person under the age of 18 any dangerous fireworks. It is illegal for any retailer to sell or transfer any safe and sane fireworks to a person who is under age 16.
Permits are required for public fireworks displays. With a public display permit, the sale, possession, transportation and use of fireworks for the public display is allowed, but for that purpose only.
Cities and counties may pass stricter laws to regulate or prohibit the sale, use, or discharge of fireworks within their jurisdictions.
