Can a Lighter Explode in a Dryer?: 1 Minute to Understand the Risks of Lighters in Dryers

If you’ve ever left something in your pockets before doing laundry, you might’ve worried about more than just a rogue tissue. A common concern is whether a lighter can explode in a dryer. The short answer is: yes, it is possible, but it’s rare. Here’s why. Lighters contain pressurized butane gas, and when exposed to high temperatures in a dryer, they can potentially rupture or, in extremely rare cases, explode. Most household dryers reach temperatures between 120°F and 160°F (49°C–71°C)—not always enough for instant combustion, but enough to create pressure inside the lighter, especially if it’s a full or nearly full lighter. If the lighter breaks open, the gas may escape and if there’s a source of ignition, like a spark from static electricity, it can catch fire. That's why it's crucial to check and empty all pockets before tossing clothes in the wash or dryer not just for safety, but for the longevity of both your clothes and appliances.

Tips 1:

When organizing your laundry or mudroom, consider incorporating designated “contents check” areas or bowls near your washer/dryer for small items like coins, keys, and lighters. As a designer, I’ve found these small solutions incredibly helpful for preventing mishaps—both for safety and to keep your space clutter-free. In fact, if you’re reevaluating your laundry room’s layout or planning a renovation, integrating thoughtful storage and functional zones is essential. Tools like a home designer can help you visualize smart solutions to make your laundry routine safer and simpler.

FAQ

Q: What happens if I accidentally put a lighter in the dryer?

A: The lighter could leak gas, melt, or—if the conditions are right—rupture. While explosions are rare, there’s a real risk of fire or smoke damage.

Q: Will all types of lighters react the same in the dryer?

A: Most disposable lighters contain butane and can be risky, but metal refillable lighters without fuel are less dangerous. Regardless, remove all lighters before washing or drying.

Q: Are there signs my dryer was damaged by a lighter?

A: Look for burnt spots inside the drum, unexplained odors, or melted components. If you suspect damage, unplug and inspect the appliance before further use.

Q: Can a dryer fire start from a lighter left in clothes?

A: While unlikely, if the lighter leaks gas and there’s an ignition source, a fire could occur. Prevention is key—always empty pockets.

Q: How can I design a safer laundry room?

A: Incorporate accessible storage and reminders to check pockets before starting a load. Using layout tools during planning can customize these features for your household’s routines.
