Steel toe boots are usually crammed with other useful features too. They'll typically be made with extreme puncture resistance in the sole, electric shock resistance for when the ground is electrified, grooves for safely climbing ladders, soles that give you the ability to walk on wet or oily smooth hard floors, better ice grip, and often are waterproof too.

I have started to wear toe cap shoes as a daily footwear. Currently burning through 3rd pair. Superior grip on the soles, helps a lot in the icy climate here in the north. I also have bad habit of catching things or resting heavy stuff on my toes, so toe caps help on that too. They also give much more support for the ankle than basic runners, and for my feet are much more comfortable and roomy than ordinary shoes. Finding a good fitting pair of shoes is always a pain, so now that I have found ones that I like, I just keep wearing them even outside the work. Surprisingly, they aren't much pricier than good regular shoes.

The thing that really elevates a lab coat to S-tier isn't just nomex. It's having snaps instead of buttons. When your lab coat needs to come off *right now* you don't want to be fiddling around with buttons. If your coat doesn't have snaps, adding them is super easy, takes 10 minutes to install if you've never done it before.

[@4NeonFun]

Aw snap! There are several TikToks out there that can show you how to install them but some snaps can be installed like a button and if you know how to sew a button, you can install these fasteners. Velcro could be another alternative to use but the added surface area will take more time to stitch each side and an "X" through the diagonals for added reinforcement. Easy don & easy doff. Just make sure whatever you're working with has safety ratings to use in the lab.

In the Fall of 2021, I had to write an ethnography on any culture of my choosing, and I decided to ask my brother if I could show up at his workplace, make observations, and ask his peers questions. I thought it would be an interesting topic to write about since he's a mechanic. His supervisor was okay with me coming in and taking notes on their workspace. When I got there, all of his peers thought I was either with OSHA or the union, and they got very hostile, but my brother defused the situation by telling them that I was his brother just doing this for my term paper. They cooled down, and I got to work, though they were all ready to throw their tools at me before they knew about it. I came in for several weeks to see how they worked with each other. When I tell you that it was very unsafe in there, it was VERY unsafe. There would be car parts scattered all over the service bay, fluid spills, and some of the guys there were washing their hands with the degreasers that they'd use to clean the parts (if I remember correctly, this one guy was using solvent 150 to clean his hands with, and it smells like a mix of scraped metal and gasoline). Some of them never used goggles or gloves, even when using angle grinders. The latex gloves they had to work with would fall apart when using the degreaser too, and for whatever reason, they weren't being given different gloves for it. A lot of the other things they used in the shop (cleaners, fluid, etc.) had some nasty chemicals in them (hexane, among others), and they just weren't following basic safety while using them. There was also one week, where apparently, someone left the engine running in one of the cars while there was a leak, and the whole engine caught fire. I missed seeing it by about an hour. After doing all the research about the industry, I found that a lot of mechanics actually suffer from eye damage, among a lot of other health problems, as a result of constantly being exposed to the chemicals they work with, and the prevalence of these problems increased with their experience in the field. The entire project was an eye-opening experience as to how unfairly mechanics get treated, including poor pay and poor safety; yet for some reason, they still stayed there because they loved the banter, the fake arguments, and the culture they created for themselves in a small service bay.

Steel toe cap boots (or kevlar plate toe cap boots...) should be SSS tier. Everything a normal boot does, plus not losing your toes when you drop things, usually having puncture resistant soles, and often being treated to be chemical spill resistant are all good. Even more so when they're stitched and the soles don't dissolve or shatter in common to moderately rare solvents. *And* they're usually ankle boots, providing support in the event your lab floor gets a bit slippery, or you tread on a spill, and providing a small amount of extra protection if you spill something and it splashes at ground height. Dust masks also have a hidden advantage - they stop you accidentally blowing on the powder you're measuring, and scattering it. :P

[@4NeonFun]

N95s (AKA dust masks) are often used in the medical field as they filter out 95% of airborne microparticles. When properly fitted, they provide an excellent seal and can be easily combined with other PPE such as face shields & glasses/goggles in high risk scenarios. N95s are much cheaper and less bulky than full respirators. (meaning the facilities have no excuse not to provide those) Good shoes are always important and it's tough to find shoes that aren't porous, but it's important. Mark's has plenty of options for different settings. It's also important that they're comfortable and that you're mindful of normal wear and tear that could damage the integrity of the footwear. Anti-slip footwear is key as there's always a fall risk in the presence of spills. Falling down is bad enough as you could hit your head but you could also have a chemical bath. Puncture resistance is one feature that often gets overlooked but you never know when you'll step on something sharp. Also, while the steel toes offer protection, they don't make you invincible, if enough force is added, that plate acts as a lever and could sever your toes clean off, but if you get to the hospital fast enough, they might be able to reattach it but that's infinity better than having your toes completely crushed under the weight and ultimately losing them for good.

I once took a blacksmithing class at a re-enactment site. We were told to wear an outer layer of cotton or wool - jeans, sweatshirts etc - and NOT ONE STITCH of synthetic that a spark could land on. I hadn't packed clothes like that for the event, but the gift shop had some cotton sweatshirts with neat designs on them, so I bought one. And I borrowed a pair of jeans from my daughter-in-law - she and I wore the same clothes and shoe sizes then. After she fell out of a canoe later in the event I loaned her my clothes and spare shoes.

[@_lime.]

I was working in a brick yard as a summer job a number of years ago. Another worker and I were standing as a forklift operator brought a pallet of paving stones into that section of the yard. He hit a bump about 2 meters away from us. Turns out someone had taken a couple stones off the pallet and had cut the strapping to do so, however the strapping was still holding on even though it was cut. The operator had assumed the pallet was still strapped up and therefore wasn't worried about moving it. Naturally as he hit the bump the whole pallet spilled paving stones onto the ground in front of the forklift and right up to and onto our feet. Thankfully we were far enough away that there were just hitting our toes and didn't blow out our shins, but I certainly was thankful for my steel toes. Remember, you may not think it likely that you'll make a mistake requiring PPE, but you can never underestimate the stupidity of others.

vinyl gloves are essential for working with nitric acid of concentrations of 86% and above. While it is uncommon to work with fuming nitric acid, if you were to spill even a drop of it onto latex or nitrile gloves they would spontaneously burst into flames, melting the nitrile/latex gloves into your han, making them almost impossible to remove. vinyl gloves have decent resistance against this and will not catch on fire or even heat up, and it takes time for the nitric acid to penetrate the vinyl gloves. They are extremely useful in some situations

This is a story where I leared how important ppe is. I once had a really terryfying contamination in my kitchen. When I was 14, I was preparing some very toxic and corrosive chemical called 'pineapple on pizza'.

Big one for people with animal dander allergies working in biomedical or biological research labs that have mice. Keep an N-95 or KN-95 mask in your pocket or always put it on before entering the room since you might not realize that mice have been brought into the main lab room until you feel the swelling of your lymph nodes.

When you feel too comfortable in dangerous circumstances: stop and re-think what you are doing. Twice. Three times. Think of your loved ones, unless you don't have any. I work on heights, mostly 50-70m above the ground (say, 150-200ft). Two years ago I was a witness of someone climbing with no protection gear. When I asked the guy, he just shrugged and started climbing anyways. Interestingly his colleague broke a toe that day, a metal frame fell on his foot while he didn't wear protective shoes, 'cause "it was too hot". Yes, they got all necessary protection from the employer, yet the attitude was their own. Two contractor workers died recently (last month). There was excessive icing all over the constructions, and they kept working with all the bad habits they gained over the years. It all happened within two weeks, and shook my coworkers much, some were shocked "but how?", others did some deep re-thinking. Don't make the *mistake* of being over-confident! Yes, I felt over-confident too. Now I try to maintain humility over routine. It is just a matter of time until something fails *while* you are vigil and careful. Why shorting the time?

The problem with most heat resistant gloves is that they are made of fabric and don't stop hot liquids (like water on top of the bottle caps in freshly autoclaved bottles). So, you can still burn yourself when picking up wet objects that are hot. The big problem with cryo gloves is the lack of tactile sensation and grip. I've had a little microcentrifuge tube slip out of my cryo glove and fall down to the bottom of the -80°C freezer which meant I had to take everything out of the freezer to recover my tube...

[@matthewmalaker477]

An important thing that wasn't mentioned about laser safety goggles is that they don't all protect from all wavelengths, and the goggles can have rated to different exposure levels across the wavelengths it is protecting you from. Goggles can completely protect you from violet lasers but offer no protection from IR lasers. Each pair of proper laser safety glasses has a code on one of the lenses detailing what wavelengths it is rated to protect for as well as the level of protection. You should always read the specification of a pair of laser safety goggles before putting them on and expecting to be protected. You could go instantly blind while wearing goggles because you aren't wearing the correct type. Any optics lab with any respect for safety (and workplace safety regulations) has a multitude of safety precautions in order to prevent blindness. A lot of labs (particularly those with class 4 visible and class 3B and above IR lasers) have physical barriers (walls) to physically block laser light from reaching the door. Some are built like darkroom with the rotating air-lock like door, and many have automatic kill switches that immediately turn off the laser if a door is opened or someone enters the laser exclusion area. I'm a graduate student at the College of Optical Sciences at the University of Arizona. Virtually every lab has high power lasers in it, many of them well into class 4. We had to take a laser safety training course before we could even dream of working in a lab or taking a lab course. You do not mess with lasers. They are incredibly useful and fascinating tools, but they absolutely deserve and demand respect. It only takes one mistake and you can instantly go permanently blind. It's not like some of the stories in the chempolation series where being quick on your feet to wash out your eyes can save your sight. You can instantly cook your retinas before your body even recognizes there's a problem. Wear the correct pair of goggles. It's not a game.
