“Alcohol and fire do not mix,” Maureen Vogel of the National Safety Council (NSC) told CNN. “You shouldn’t pair flammable items; it’s the proverbial recipe for disaster.” So, if you’re doing your due diligence of keeping your hands disinfected and you want to set off celebratory fireworks, you could be putting yourself in danger. That’s why Vogel recommends that you “keep hand sanitizer away from the fireworks area.“ae0fcc31ae342fd3a1346ebb1f342fcb RELATED: For more up-to-date information, sign up for our daily newsletter. Dhaval Bhavsar, MD, medical director of the University of Kansas Medical System’s Burnett Burn Center, issued a similar warning to a local NBC News affiliate ahead of the holiday weekend. “If they have hand sanitizer on and … [are] lighting the fireworks, I think they could have a high risk of having a burn injury,” he said. “It can be a third degree burn because alcohol is potent and flammable.” Dee Shelton, a fire and life safety educator with the Greensboro Fire Department in North Carolina, posted a video demonstration to show “just how flammable” hand sanitizer is. In the video (which you can watch below), Shelton explains that the alcohol in hand sanitizer burns “clean, so it has the blue flame instead of the orange flame,” which means “you may not even know that it’s on fire.” So, what can you do to stay safe from both COVID and burns during this unique July 4th weekend? “If you use alcohol-based sanitizer, wait at least five minutes and make sure you rub your hands clean and there is no residue of alcohol” before using fireworks, Bhavsar says. Fireworks, of course, present their own set of dangers—hand sanitizer aside. The U.S. Consumer Product Safety Commission’s (CPSC) Fireworks Annual Report, which was released in June, estimates that there were 10,000 firework-related injuries treated in ERs nationwide during 2019. Seventy-three percent of those injuries occurred around Fourth of July weekend, and sparklers were responsible for more of those ER visits than any other kind of firework. And therein lies another issue that makes COVID and July 4th a risky combination. As Donna Skoda, MS, RD, a health commissioner in Ohio, recently pointed out to Akron Beacon Journal: “You have a cloth that is flammable covering your face and you are swirling fire around your head.” You do the math.
