Summer’s officially here, which means—for a good chunk of you— you’re taking some well-deserved time off to do a bit of traveling. If you’re doing that, then let’s be honest, you’re going to take a few shots of yourself while you’re away, and you wanna get your selfie game on lock.

There’s plenty of guides on the web that will walk you through how to take the perfect snapshot. But while most of us know that, for example, natural light is flattering and that you shouldn’t smile like a sociopath, there’s not nearly enough guides out there telling you what not to do. So, we decided to compile a cautionary list of selfies-turned-tragedies that will (we hope!) leave you with a few practical tips to remember the next time you’re, say, snapping a pic in front of some national landmark (or in your hotel room, we won’t judge).

Don’t: Lean on the Artwork

People tend to be pretty divided on whether you should take a selfie in an art museum. Personally though, I say go for it—it’s a great way to commemorate some beautiful pieces (and your beautiful mug)! There are a few caveats though, and the biggest might be please, for the love of god, don’t touch the art.

Otherwise, you might end up like this Los Angeles woman who made headlines in 2017 when she inadvertently backed up into an exhibition and ended up causing about $200,000 worth of damage. You can see her in the video above. It’s about the 11 minute mark when she slips, mid-pose, knocking into the pedestal behind her. And because this exhibit was, more or less, an elaborate setup of very expensive dominos, her flub set off a chain reaction that ended with about a dozen of these pieces knocked over—and three broken beyond repair.

Don’t: Disrespect the Wildlife

Since tourists have been flooding national parks in record numbers recently—and you might be one of them—here’s a few pieces of parktiquette (park etiquette) to remember before you go: take your trash with you, be polite to the blatantly overworked staff, and stay away from the animals.

That last one might be pretty obvious to some of you, but there’s still far too many cases of people getting too touchy. Case in point: in 2016, a tourist visiting Yellowstone Park got gored by one of the park’s many bison while trying to snap a selfie. Thankfully, her injuries weren’t too bad, but—as one park ranger told CNN at the time—she was the fifth case that season of someone getting too handsy with these hulking, aggressive beasts. Hell, the park reported three cases of bison-based injuries in the last month alone, which shows we clearly haven’t learned anything. Reader, I assure you, no selfie (no matter how sick) is worth being rammed head-on and tossed in the air by a 1,000 pound wall of muscle.

Don’t: Go After Your Dropped Phone

Look, I get it. Accidents happen. But if you’re gonna take a quick pic next a historic landmark—like, say, an active volcano—you want to do your best not to drop your phone down into it. Or, if you do, you shouldn’t be like this guy who reportedly fell into Italy’s Mount Vesuvius this week after trying to rescue his phone, which had slipped from his hands and straight into the volcano post-selfie. Considering how this is, again, a very active volcano, the man was lucky get out with only minor injuries by the time park officials hauled him out. Hopefully the selfie remained intact, too.

Do: Watch the Weather

Like most of the tips on this list, this one should be pretty common-sense: no selfie is worth going outside into some dangerous weather event. There’s way too many stories of people taking selfies in front of tornadoes and selfies in front of earthquakes, frankly. And then last year we got one case where 11 selfie-taking-tourists in India that were snapping away outside during a lightning storm were (shockingly) struck by lightning and instantly. Y’know, because they were outside. During a lightning storm.

Don’t: Selfie and Drive

If you try to take a selfie while driving, you are probably gonna crash. If you try to take a selfie with a selfie stick while driving, you, again, are probably gonna crash. If you try to take a selfie, crash into a lake, and then try to take another selfie while you’re standing on top of the wreckage, as one Canadian woman did earlier this year, then you need to ask yourself if your selfie addiction has gone too far (it has).

Selfie and Boat

Anyone who’s ever gone kayaking can attest to the serene and (dare I say) downright selfie-worthy scenery you’ll see while out on the water. They can also probably attest to how easy it is to inadvertently end up flipped over, especially with a few other people onboard. Case in point: last year, a boat full of tourists capsized in Indonesia when the 20 of them funneled to one side to take a group selfie. Nine of them ended up drowning.

Ignoring the... somewhat questionable safety precautions onboard (local reports noted that the boat was both seriously overcrowded and also being steered by a 13 year old), this is still a pretty good reminder to take those group selfies on land. I promise they’ll look just as good.

Do: Make Sure You’re Standing Somewhere Steady

Speaking of snapping those selfies on land; you should also make sure you’re not standing somewhere on the brink of collapse. If you don’t you might end up with a case like this one, also out of Indonesia last year, where a family of vacationers gathered for a group selfie on top of a boat dock. It ended up buckling under their collective weight, and five of them ended up drowned in the wreckage.

Maybe this is a good reminder to, uh, stay away from any sort of large bodies of water while you’re taking a selfie, just a to be safe.

Don’t: Stand on Top of a Train

Speaking of places you shouldn’t take selfies: there’s a frankly disturbing number of people that have tried to snap one while standing atop a train. While I get the urge (it does look kind of badass), it’s pretty dangerous for two reasons. For one thing, trains are tall, and falling from tall things generally isn’t advisable.

The second, less obvious reason is that most modern-day trains—like the metro-line you might have in your neighborhood—are electric. This means that they need some sort of live wiring to keep them up and running, and this usually means an overhead line, which carry 25,000 volts of electricity on average.

If you’re wondering what happens when you touch one of these wires, look no further than the many, many news stories detailing the aftermath of train-top selfie attempts: one Romanian teen burst into flames and then died from the resulting injuries. The same thing happened to a teen from India last year. More recently, another teen just died on impact with the cable. In all cases, it’s a pretty clear sign to not selfie there.

Don’t: Crop-Stomp

The average crop field is both sprawling and majestic, which, on paper, makes it perfect selfie fodder. And considering the number of reports out of Canada this summer about selfie-ers trespassing into people’s private canola fields, it looks like at least a handful of Canadians agree. The only problem, as local police were quick to remind residents, is that crops are also food, and pretty expensive food, in fact—one estimated that the damage done by one selfie-r stomping on crops totaled $2,000. These cases, as the same cop pointed out, could also result in a criminal charge for the photographer involved.

Don’t: Touch the Sea Creatures

Everyone loves a good beach selfie, and why wouldn’t they? The lighting’s great, the ocean’s beautiful and everything’s just shiny. That said, no matter how hot you’re looking in that new bikini, the second you try to bring a shark or a dolphin out of the water and into the frame with you, your hotness rating’s gonna plummet. Animal abuse (even if that animal has gills or a blowhole!) is never a cute look on anyone, honestly.

Don’t: Touch the Turtles, Either

Back in 2015, tourists swarmed the beautiful beaches in Costa Rica in the middle of the egg-laying season for sea turtles in the region. The mass chaos that ensued from all the folks trying to snap a pic with one of these green guys while they were ashore was... kind of embarrassing. So embarrassing, in fact, that reports at the time stated that more than a few turtles simply saw the crowds flocking around and just turned tail back into the water, without laying anything at all. And can you blame them?
