Whether it's a Fourth of July celebration or a Memorial Day cookout, fireworks can add excitement to any backyard gathering. However, setting off fireworks carries inherent risks, and irresponsible use could make the night memorable for all the wrong reasons. Below, we’ve asked experts to discuss backyard firework safety, including the potential fire hazards and other safety concerns.

How Bad Is It To Set Off Fireworks in Your Backyard?

It’s not inherently bad to set off fireworks in a backyard, but there are numerous factors to consider. James Turver, Director of Galactic Fireworks, says three things need to align before it’s safe to set off backyard fireworks:

  1. You’re legally allowed.
  2. The conditions are right.
  3. You’ve got space to do it properly.

“Check your local rules first, because they vary enormously. What's legal in one state or county is banned outright in the next. Then look at the weather. A dry, still evening is what you want. Wind carries sparks onto fences and roofs, so if it's gusty, drought-dry or there's a fire warning in force, leave them in the box,” he recommends.

Additionally, Turver warns against specific circumstances that would make setting off backyard fireworks a risky consideration.

"Don't set them off if you're boxed in by trees, sheds and fences, if there are people or houses close behind the firing line or if you've had a few drinks. A lighter in one hand and a beer in the other is how people get hurt. And never go back to one that hasn't gone off. That 'dud' is one of the most common ways people lose fingers,” he warns.

How Much Space Do You Need To Set Off Fireworks?

While the National Fire Protection Association (NFPA) requires strict separation distances for professional fireworks displays, there isn't a one-size-fits-all space requirement for consumer fireworks. The amount of space needed depends on the type of firework being used, so homeowners should carefully follow the manufacturer's safety instructions.

In addition to providing adequate space, homeowners should ensure the launch area is clear of trees, power lines, vehicles, dry grass, sheds and homes. Spectators should remain at the minimum distance specified by the manufacturer, and if you can't provide the recommended clearance, it's best not to use the fireworks at all.

What Makes Fireworks Dangerous?

According to the National Fire Protection Association (NFPA), fireworks started an estimated 32,302 fires in 2023. However, fire risk is only part of the equation. Fireworks also cause thousands of serious injuries each year.

"Roughly 14,700 people ended up in American emergency rooms with fireworks-related injuries last year, and 11 died, both up sharply on the year before, per the Consumer Product Safety Commission. Burns are the most common injury, and hands, fingers and faces take the worst of it,” notes Turver.

But it’s not just the big, explosive fireworks that cause these injuries. He warns that sparklers, which people often hand to children without thinking, can burn at up to 2,000°F and send roughly 1,700 people to the ER each year.

Pro Tip: If you want your kids to get in on the fun, swap out sparklers for safer alternatives like glow sticks, silly string or party poppers.

Legal Considerations for Backyard Fireworks

Beyond the risk of fire and injury, setting off fireworks may expose you to legal liability if something goes wrong. Edward Susolik, CEO, President & Trial Attorney at Callahan & Blaine, says state laws are only a starting point, and local ordinances and HOA rules must also be considered. Even still, he notes that setting off fireworks could make you liable for anything that happens as a result.

“The moment you set off fireworks and a spark gets on the neighbor’s roof, or a guest suffers burns, is when you could face trouble,” he explains. “It doesn’t matter if you bought them legally or followed the state and local requirements if the conditions made it unsafe to do so.”

Backyard Fireworks Safety Tips

While there is always some risk involved, fireworks can be enjoyed safely when used responsibly and within legal limits. If you choose to set off backyard fireworks, here are some tips to help ensure you and everyone involved stay safe:

  • Keep a hose and a bucket of water nearby. Keeping water nearby is always a good idea when dealing with flames and fireworks, and a bucket of water is a must for soaking spent fireworks and sparklers.
  • Follow the manufacturer’s instructions closely. All fireworks are different. For best results, always pay close attention to each manufacturer’s label.
  • Never relight a dud. If a firework doesn’t go off upon ignition, never attempt to relight it. Instead, wait at least 20 minutes before approaching to ensure no delayed ignition occurs.
  • Keep spectators back. Ensuring spectators keep their distance from the launch site is crucial to their safety.
  • Avoid alcohol. Alcohol and fireworks aren’t a good mix. For everyone’s safety, leave the alcohol to the spectators.
  • Soak spent fireworks before disposal. Fireworks can stay hot long after ignition, so it’s best to soak them and fully extinguish them before tossing them in the garbage.
  • Be mindful of pets and wildlife. Fireworks can cause significant stress for pets, livestock and wildlife. "July 5th is one of the busiest days of the year at animal shelters, because terrified pets bolt from the noise,” notes Turver. “If you're firing in a backyard, your neighbors' dogs, cats and horses pay for it too, and so does the wildlife.”
