While fireworks can always pose some threat, it’s generally safe to store them in your home if you take proper precautions. Learning how to properly store unused fireworks is a key part of firework safety, and we’re here to tell you everything you need to know. Here’s our complete guide on how to store fireworks.

In very hot areas that reach over 130 °F (54 °C), fireworks can ignite. Therefore, try not to keep fireworks in a hot car, attic, or garage if there’s a risk of these places getting extremely hot there. Instead, opt for a cooler location, like a basement.^{[3]

Store the fireworks in an area with low humidity.

Although a couple of muggy days aren’t likely to ruin your fireworks, if you live in an area that is very humid (regularly over 50%), it’s best to keep your fireworks inside or in an air-conditioned space. With too much humidity, the gunpowder in your fireworks will collect too much moisture to be able to light.^{[4]

Keep them away from flames and water.

Open flames and sources of water are fireworks’ worst enemies. A firework exposed to an open flame—like any flames from your kitchen, an outdoor barbecue, or a fire pit—can ignite, causing serious damage. Water will render your fireworks unusable, so keep them out of any location where they might be exposed to rain or leaks.^{[5]

Download Article

During an extreme weather event, such as lightning or power surges, it’s possible that these devices can overload and set nearby fireworks off. Although the chances of this happening are slim, it’s best to be safe and store your fireworks away from any electronic devices.^{[6]

Avoid moving fireworks around too much.

Download Article

Moving around your box of fireworks too often can cause the contents within the firework to spill or otherwise fall apart. This can lead to your firework failing to light when you need it. When you’ve found a good place for your fireworks, try not to move them again unless it’s really necessary.^{[9]

Store fireworks for no longer than a couple of years.

Download Article

Although properly stored fireworks can last for several years, it’s normally best to use them or get rid of them within a couple of years. You can save fireworks for next year, but over several years, the gunpowder inside can become unstable. This might cause them to not ignite the way they’re intended to.

11

Check your local laws about fireworks.

Download Article

Local laws limit your ability to store fireworks. In the United States, most local communities have their own rules about keeping and lighting fireworks. Your city or state may not allow you to keep fireworks after the 4th of July or other holiday events. Check your local laws to be sure that you can store them in the first place.^{[13]
