It is just as likely for a vape pen to explode as any other electronic device. That’s the risk that comes with technology. Chances are, your vape won’t explode. However, if you notice that it is getting hot or the batteries are swelling, it’s best to stop using the vape and bring it in to get looked at by one of our Kure associates. They can help identify the issue. An exploding vape is the only kind of vape that could set off a fire alarm. Vaping as you normally do will not set off any fire alarm unless you are blowing directly into it or have several people vaping at the same time in an enclosed space. Vapor is much less dense than smoke, so it takes much more vapor to set off a smoke alarm.
