Or strong caustic. (I was calling the surgery; other people were hosing him down under the emergency shower. I heard afterwards that their prompt action saved some of the sight in one of his eyes.) I never trusted safety glasses, only goggles.

@@mikesummers-smith4091 Yeah, bases in unprotected situations scare me far worse than acids do.

[@At0mix]

@@moskon95 I was always taught to make adequate risk-assessments for myself. Thick rubber gloves are recommended for handling strong acids, but the lack of fine motor skills as a result of using those gloves can create an even more hazardous situation. So I can see why you would opt not to wear them. Just consider the risks involved in what you're doing beforehand, and act accordingly.

[@thomasm5714]

As an ophthalmologist, I really appreciate this video. Quite apart from the danger of acid and (worse) alkali burns, penetrating injury can be blinding, even when the particle involved is tiny. The merest speck of intraocular iron, for example, will set up a chronic inflammatory reaction that has the potential to cause blindness weeks or months after the initial event. Infective endophthalmitis is also a possibility if even a single viable bacterium is carried into the eye by a penetrating foreign body.

[@drrocketman7794]

I had a friend drilling hardened steel with a carbide tipped high speed steel bit. He was leaning in close, dripping oil into the hole from an oil can. The drill bit hit a slag inclusion in the metal, binding it. The drill bit failed catastrophically, and a piece of the drill bit stuck in his heavy apron, sharp end first. Another, larger piece flew into his safety glasses, knocked them askew and gouged a piece of polycarbonate out and leaving the groove slightly blackened. Another fragment slightly injured his finger, which he wiped off and put on an adhesive bandage. He would have been much more seriously injured without safety gear, and would probably have lost vision in one eye from this incident.

True, but it might convince some people to wear safety glasses. If it saves just one person's vision, job well done.

[@aboriani]

I worked in a workshop and right above the lathe there was a pair of safety glasses exposed with a nail stuck one inch into one lens. The person which eyes were saved hanged the goggles to be seen by everybody as a reminder of what could have happened if he wasn't wearing them.

In high school, my woodshop teacher put up a picture next to the safety googles. It was a x-ray of a man with a nail in his skull. Underneath it was a note that said "Don't let this happen to you. Wear eye protection."

[@ManicEngine]

When I was in school, our woodshop teacher gave us a safety lesson after he came back from the midyear holidays missing a finger

[@LexiPopuli]

I agree with the comments below about science teachers showing this to pupils. However this video should be shown in every Health & Safety training as an example of why H&S exists and everyone who has the training should before the video be given a pair of cherry tomatoes to look after before the start of the training. See how many are safe by the end.

Even back in elementary school science class in the 1970's we wore them. Back then they were clunky plexiglass goggle things but thankfully we never had to test them out. Personally I still prefer the goggles as the cover the sides of your eyes too and you can wear them with prescription glasses.

Same here. I use Bolle ones most often.

Goggles are better- much lower chance of ricochet fragments getting into the eyes. (and make sure they fit properly- I've sparks from a disc cutter bounce through the gap between goggle and nose before.

I go to a technical school and took a welding class for about a week during rotations, almost every lab there stresses the importance of safety goggles but this teacher took it super seriously. At the start of the rotation, he was talking about lab safety, going over stuff like leather boots and heavy pants, he asked the class how metal fragments are removed from an eye? People would guess stuff like "they're pulled out with tweezers" or "the eye has to be removed" The teacher said, "The fragments have to be removed with a drill, during this operation you can't be anesthetized since the eye has to be held in place and the eye rolls around if you're unconscious." He also told the story of a student from multiple years ago who got some metal in his eye, the student didn't tell anyone and for about week had metal in his eye, slowly his vision in that eye got darker and more blurry. He ended up going to the teacher and admitted what happened. He went to the hospital and got it removed, his vision never fully healed in that eye.

[@ChiTownTino]

So many great educators on KZbin! I wish there was away to organize these videos to make it easier for teachers and parents to link them to the subject they are currently working on. It’ll also give students with less access to education more options.

[@tactiletinkerer]

As both a former decades-long mechanic and motorcyclist, eyepro is a woefully under-respected part of safety gear... I've personally exp'd a shard of steel the size of my fingernail embedding in safety glasses while grinding on a part... and of course, helmet visors catching rocks, bees, and steel tyre carcass bits, hours from medical attention. Kids are 'invulnerable' because they haven't exp'd their bodies failing them... yet. :D As Martin says... only one chance to eyepro.

[@BlankPicketSign]

Legit if I can I wear safety glasses and then a Plexiglas face shield over my whole face over top that

[@ghuegel]

Yeah, if you're working with potentially explosive stuff, you need more than safety glasses.

[@raiyiar]

I mean, if you're working in the lab and an explosion in glassware is a risk, then of course face masks are the bare minimum :> but if the biggest realistic danger is corrosive liquids splashing in your eyes, you don't need as much physical resistance, and a bit of sodium hydroxide on your cheeks is much more easily cleaned off and doesn't leave permanent damage, as it would in your eye.

[@pietrotettamanti7239]

Don't stop at the full face mask. Don't even get out of bed in the morning. You could slip and break your skull.

[@manictiger]

Well, there is the fact that we can repair almost anything in the body that isn't: The eyes, the brain, the spine. So, yeah, until someone can rebuild an eye and optic nerve from stem cells, best to just protect them.

[@MrNikwillig]

Man, for years I didn't bother using safety glasses while working around the house, simply cause I found it too annoying to dig out the dusty, dirty old pair from the toolbox. This changed after adjusting an old chainsaw that I had gotten to run for the first time in 30 odd years. While test cutting, a tiny shard of wood lodged itself just barely in the white of the left eye... Spent ~10 min gently digging it out myself as it was shallow. After that, got myself a set of tinted safety glasses, and now I never leave home without wearing them... Simply cause I still can't be bothered to go digging through that toolbox for those old crappy ones. So, remember folks, safety first!

[@manictiger]

Access is important, too. All my important stuff is near my standing desk (where I spend a lot of time). Respirator, weapons, goggles, gloves, hearing protection, etc. Everything else is also in places that make sense (all the survival stuff in one spot, all the tools in another, etc.)-- but the most important stuff is within arms reach.

[@ThinkingSpeck]

I wear sunglasses pretty much all the time outside, and they're always rated safety glasses. Cheap, comfortable, easy to replace, and protect my eyes when necessary. Works great for me.

[@doctorwigglespank8933]

You definitely cannot use those again. Any time any piece of PPE has served its true purpose, i.e. taken the brunt of some sort of accident - it is always to be discarded. Very expensive gear such as safety harnesses or breathing protection has to be re-certified by an authorized tech, who will either restore it or discard it all together. This especially is true for helmets. If your bike or bicycle helmet, or hard-hat has visible cracks, marring or obvious sun-bleaching - *replace* *it* !

You know, this experiment and what it is trying to represent is somewhat misleading! This is CHEMICAL lab, it should be performed with *chemical safety goggles* and maybe ink in the tube instead of water, so that it can demonstrate where the liquid particles hit. Many people think that machine shop safety glasses, as used in the first demo (designed to protect from flying particles) are adequate. Chem labs must require the goggles with the soft face-conforming edges. They are more uncomfortable and fog up, so many students opt for the ones without the seal, which flying liquids can bypass. :/
