The National Fire Protection Association says fireworks start more than 19,000 fires across the U.S. each year. So what can you do to be as safe as possible this Fourth of July?

Fairfield police say they’ve been responding to an increasing number of fireworks complaints each year. They want to make sure residents know the laws surrounding fireworks usage.

In Connecticut, aerial and explosive fireworks are illegal — only sparklers and fountains are legal. Those 16 and older can buy legal fireworks.

Even sparklers can burn at temperatures of 2,000 degrees which can cause serious burns. Officials say make sure fireworks are properly doused with water before throwing them away.

That means have a garden hose or a bucket of water nearby when using fireworks, and be sure to not throw them directly in the trash. Instead, put them in a separate container.

And if a firework doesn’t discharge, do not pick it up. Instead let it sit, then douse it.

Fairfield police say residents can call them if they see any illegal fireworks being used.
