Why danger symbols can’t last forever

Why danger symbols can’t last forever

You probably know how this symbol is supposed
to make you feel. And this one. This one too, even if you’re not sure exactly
what it means. But what about this? This symbol — The Jolly Roger — was once
one of the most feared symbols in the world. It represented death, pirates, and poison. But today, it’s associated more with treasure, blockbuster
movies, or Halloween than actual danger. We are surrounded by icons that warn us: what
to stay away from, what not to do, what to be afraid of. But how do you design a symbol in a way that
will last across generations and languages? It turns out that is an incredibly hard thing
to do. Back in the early 20th century, there was
an urgent need for a new kind of warning symbol. At the time, there was no universal standard
for communicating the presence of dangerous biological materials. Laboratories at the US Army used an inverted
blue triangle. Those at the Navy used a pink rectangle. The Universal Postal Convention used a white
staff-and-snake on a violet background. There was no consistency in the visual language
used to communicate risk. That was dangerous, and could lead to accidental
infections. So in 1966, a group of engineers and designers
at Dow Chemical set out to create the best possible icon for biohazardous materials. They laid out six design criteria. First, it needed to be visually striking,
so that it would draw immediate attention. That ruled out simple shapes like those from
the Navy and Army. It also had to be unique and unambiguous,
in order not to be confused with symbols used for other purposes. That ruled out the snake-and-staff, which
has multiple versions and has a pretty vague meaning as a general symbol for medicine. On top of that, it had to be quickly recognizable
and easily recalled. Had to be easy to stencil. And rotationally symmetrical, in order to
appear identical from all angles. And lastly, it had to be acceptable to groups
of all backgrounds. So the Dow Chemical team designed an experiment. Charles Baldwin, an environmental health engineer
behind the experiment, said that the team “wanted something that was memorable but
meaningless … so we could educate people as to what it means.” They showed a set of 24 symbols to 300 people
from 25 American cities. There were 6 newly-designed biohazard markers,
and 18 common symbols — things like Mr. Peanut, the Texaco star, the Shell Oil symbol,
the Red Cross, and a swastika. Participants were asked to guess the meaning
of each one, which was used to assign each one a “meaningfulness score.” A week later, the same participants were shown
those original 24 symbols, plus 36 more. They were asked to identify which symbols
they remembered seeing in the previous round of the study. Among the six competing biohazard designs,
this one stood out. It scored the highest in memorability, but
the lowest in meaningfulness. So it was unforgettable, but also a totally
blank slate for designers who wanted to give it meaning. And with that, it became a national standard. It’s easy to overlook how much visual communication
work these symbols are doing. They’re simple — you only need a straightedge
and a compass to recreate them. And unlike most other hazard symbols, they
don’t reference an existing physical object or idea. But they’ve remained iconic for decades,
helping people recognize serious dangers that may remain a threat for thousands of years
to come. And that raises the question: could the meaning
of those symbols stand the test of time? Few people have pondered that question quite
like Gregory Benford. He’s a physicist and science fiction author. In the 1990s, he was invited to work on the
Waste Isolation Pilot Project, or WIPP. The WIPP is a massive storage site for radioactive
waste in the southeastern plains of New Mexico, organized by the US Department of Energy. Benford was brought in to help calculate the
probability that someone or something would intrude on the site for as long as it remains
dangerous — approximately the next 10,000 years. “Well, name anything that has persisted
for 10,000 years. Any institution. There isn’t any. The record is probably something like the
Catholic Church or the core of the Jewish religion, which tells us something about what
really lasts.” The meaning of a symbol can change over time. Like the Jolly Roger, which wouldn’t work
for the radioactive threat at the WIPP. “If you’re approaching the WIPP facility and
you see a skull and crossbones you might think, ‘Hey this is where the pirates buried their
treasure.’” So how do you indicate a long lasting danger
across any language? Since the 1970s, engineers, anthropologists,
physicists, and behavioral scientists have proposed different solutions to that problem. One strategy was to add context to the symbol. By illustrating cause and effect in a three-part
cartoon like this, designers could communicate the idea even if the symbol lost its meaning. But this kind of visual communication still
made a lot of assumptions about the user: that they would read left to right, that they
would understand causality between frames — and, of course, that the drawing itself
would last millennia of wear and tear. So other designers started to focus on creating
a warning without inscribed communication, by altering the shape of the location itself. And that yielded designs like this. Spike fields, forbidding blocks, giant pyramids:
these designs capitalized on natural instincts of fear and discomfort to keep people away. But even then, they weren’t foolproof. Designers couldn’t be sure whether they
would be perceived as terrifying or fascinating. “Conflict between these two urges: you want
people to notice it but you don’t want people to go there. Those are always going to fight each other.” So without symbols, without basic illustrations,
or physical structures, how can you effectively communicate a warning? That’s where the more philosophical design
solutions come in. In 1984, the German Journal of Semiotics published
a series of solutions from various scholars. Linguist Thomas Sebeok proposed creating an
atomic priesthood, where an exclusive political group would use its own rituals and myths
to preserve information about the radioactive areas. And philosophers François Bastide and Paolo
Fabbri proposed to genetically engineer bioluminescent cats that would glow in the presence of radioactivity. By creating songs and traditions about the
danger of glowing cats, the warning could last as long as the oldest relics of civilization
we have: culture. There’s no definitive solution for warning
people far into the future. But designing clear, inclusive symbols will
continue to be a fundamental part of how we keep people safe. We will change, and so will the ways we communicate
visually. Our warning symbols will have to change along
with us.

  1. Maybe it's just me, but the narration alternating between 2 different voices was a bit jarring and distracting.

  2. my favorite danger symbol is the one with the circle in the middle, and 3 triangles sticking out of it. i will cry when it dyes.

  3. Make something out of a pyramid or a triangle when designed in a specific aesthetic it could create the most horrific symbol. For reference you can look up for the Pyramid head in silent hills, mysterious yet horrific

  4. LOL Area 51 is the perfect example to show us that danger symbols r becoming increasingly useless against determined millennials 😂

  5. No, but the symbols we have are probably the best solution. Once the sickness is associated with the symbols, people usually figure things out.

  6. The only reason people were using the skull and bones for fun is because it had two meanings. The first being pirates. And because that is the only symbol pirates used


  8. I get the point of this video, the civilization we have now will be different 10,000 years in the future so as the symbols and writings, and maybe our language..

  9. 5:38
    "You want people to notice it but you don't want people to go there. Those are always going to fight each other"

    So how about just having people not notice it? Why not just bury it deep, deep underground in the remotest of locations, seal it up the best you possibly can and essentially hide it forever?
    I'm imagining a large dugout room hundreds of metres underground where you can dispose of all the nuclear waste you need to, surround the room with walls metres thick made of steel and concrete, seal up and destroy any entrance and let nature grow back over it so that nobody ever knew it was there.

  10. came back to this after listening to SYSK's episode on nuclear semiotics. i highly recommend it! it goes into detail about all of the things mentioned in this video.

  11. Scientists: This symbol represents radioactive activity and warns people of great danger
    Asap Rocky: Let me make this my Album Cover

  12. So I realize that this channel likes to stretch it the video for no apparent reason, it doesn’t reach 10 minutes and it answers the question at the last ten seconds of the video, basically just drives the audience into a bunch of circles and talk about ground spikes and glowing cats and then just say the obvious answer which is that the signs of danger will change as time passes, just like anything on this planet. Everything changes overtime, it’s a universal rule, simple.

  13. Very nice theme song , can you please tell me the name?ive been looking for it for year and is it music box?please tell me cause I'm not a native speaker so I don't know

  14. Well, in Canada, the skull and bones symbol still means death and poison. But mostly only when there’s an octagon or circle around it.

  15. "We can't assume that future generations will read left to right, better make a cult around avoiding our genetically engineered glowing cats instead"

  16. If the skull sign was as well preserved as many of you seem to think, we would take it so seriously and acknowledge the harshness that it wouldn't show up in kid's toys and costumes. (Not that I undestand why there has to be images of human remains on any clothing, but at least not children's.) Maybe death as is doesn't scare us that much, it simply marks the end of existence for the modern secular individual. We need to be made to think about the possibly horrific causes.

  17. I recognize the radiation symbol and the fallout shelter symbol, but most people often misinterpret the symbols as representing the same thing.

  18. this title made me think about the barrels of toxic waste, if the halfway time of some nuclear waste is several millions of years, then couldn’t it be that the colour on the barrel vanishes after a while so it will not be recognizable anymore and dangerous for future generations?

  19. I'm flabbergasted at how relevant this is and of course the comments are even better with some bringing up Drake's Equation and how we most likely won't even exist as a species in 10,000 years let alone digging into hazmat pits.

    As another solution to the biohazard problem I propose as tech improves to load up rockets with nuclear waste and launch it either to distant moons or asteroids. Since its surface is mostly hazardous materials anyway maybe just sending it to Mars is the best option leaving the Earth waste-free.

  20. One may wonder when the time comes, where we won't need to just imagine the danger of those symbols.
    Come on, a nuclear war NOT happening within the next 10,000 years? Yeah, right.

  21. If the Human Skull will eventually lose it's meaning as a symbol of warning, which is "Death", then there is no symbol you could create that will forever stand the test of time.

  22. But the radiation one won’t change unless we just don’t use an atom bomb ever again which probably won’t happen

  23. A historian in 2000 years time would find the spike field and not know it’s function and later dies making people believe its cursed.

    Well that’s if we make it in 2000 years time.
