And at some point between then and the onset of the modern office economy, the workplace safety poster has become a lost art. For one, our sensibilities regarding geysers of hilarious gore in safety education have changed. Gone are the safety videos that depicted your average warehouse as a secret murder maze and children's pamphlets like It's Great to Be Alive, which subtly informed kids that the 1950s were just a 10-year-long deathtrap invented by the Pentagon.

Reading this pamphlet is sort of like learning that McGruff the Crime Dog takes off his trench coat
and reverts to a feral state to execute convicts.

So here are 10 of the most ominous safety posters ever to grace break rooms across the globe. It's unclear if they improved morale, but these posters certainly filled workers with the fear of a dark and wrathful god -- a dark and wrathful god named DILIGENCE.

That sort of looks like a young Joseph Stalin. Can you imagine if he went out like that? If one clumsy construction worker hadn't been too hungover to come to work in 1917, Mister Trololo would've been elected general secretary by '75 and there would now be a Candy Bridge over the Bering Strait.

A lot's going on in that poster, so I've translated it in layman's terms: "Tinnitus causes you to fumble a menage-a-trois with Betty and Veronica. Look at that crazy matching lipstick -- they're trying to impress you, buddy! And if you mumble confused bullshit at them, they'll citizen's-arrest you for reasons unconstitutional. Stay out of jail: Never neglect group sex with women wearing clown makeup."

The selling point of this poster is the Grim Reaper, because he's super exasperated that the dead guy won't be able to paint his house. He's all like, "Sweet Christ, Taco! I told you not to die before 5:30 p.m. Now I have to take time out of my busy day to ferry your soul across the River Styx. And FUCK ME, you forgot to put down the primer."

(ADDENDUM: Yes, "Taco" is a normal Dutch name. In fact, there's actually a pharmacoepidemiologist out in the world named Dr. Taco Monster. I bet he gets laid like a fiend.)

"Nuts to you, buster"? Stop being blase, Macho Miner Randy ChestRug. Your co-worker is the Grim Reaper. He's a celebrity! That SOB is like the Lee Trevino of killing people. Get with the program and hide that dynamite in the latrine.

This motor pool safety poster dates back to the 1920s. I don't read Dutch, but I'm guessing that before fossil fuels went mainstream, drivers trapped evil genies in enchanted crankshafts and forced them to power automobiles using three wishes. ("Wish #1: Drive to the market. Wish #2: Drive to my house. Wish #3: Turn off the headlights HURRrrrk.")

This poster -- which encourages "proper lifting" -- would be perfectly innocent if you worked in some sort of, uh, burlesque box factory, but the Hebrew word for "lifting" is jam-packed with innuendo. Finally, a poster that sexually harasses your workers so they don't waste precious company time sexually harassing each other!

This incredible safety poster warns students about "secret cults," or criminal fraternities that operate on Nigerian university campuses. The artist went for broke, throwing in everything from Satan to cultist party girls to Jesus Christ firing Scripture passages and lightning bolts out of his hands.

"Brett came to the country club sporting a garland of primo hazels. I won't be bested by that Dartmouth fuck."

... and finally, several helpful "Know Your Shapeshifter" diagrams, which hammer home that a skin-walker might be in your midst if your cat sprouts human breasts.
