In California, fireworks are illegal in certain cities and counties due to the risk of causing serious injuries, damage, and the risk of sparking a wildfire. On Jan. 1, an 18-year-old was killed in a fireworks explosion on San Francisco's Treasure Island, where possession of any firework is illegal.However, "Safe and Sane" fireworks are permitted in certain areas and must bear the official seal. Only licensed retailers can sell these types of fireworks.
Officials described "Safe and Sane" fireworks as those that are less likely to cause injury and generally don't explode or fly."It's illegal to sell, transport, or use fireworks that do not carry the "Safe and Sane" seal, and it is illegal to possess or use any fireworks in a community where they are not permitted," Cal Fire's website detailed.
