Don't Wear Sleeves vs. Burns From Hot Chips

Nitrile medical exam gloves are a far cry from those gloves your pictures show, mate.:grin:

The brand I use, are made from material 0.00275" thick (0.07mm) and despite the pictures they laughingly show of people yanking on them, a pinch and tug will make them tear like a paper towel very fast.

Obviously, I didn't assume anything (that's not in my nature) so I tested their lack of durability (for once, a lack of durability that is desirable!) in a couple of ways. I held a glove like you'd hold a strip of emery cloth on a lathe and got it to snag very briefly on a drill in my drill press but it tore and separated into two pieces. Even holding it loosely and getting it to snag by flipping it near the rotating drill point led to it tearing. In both cases there was hardly any tug on my hands.

Neither test was particularly realistic mind you since, like @pontiac428 , I never, ever put my hands near live work (since reading his post I have started to practice the "giving idle hands work" technique too just to be even more sure and I rather like it).

These aren't the kinds of gloves you see auto mechanics wearing (I have those too, but wouldn't dream of wearing those anywhere near any machine tool; I use those for when I'm Evaporusting or wire brushing or disassembling things). The gloves I have are intended for medical examinations or surgical use.

The size I wear when using machine tools are just very marginally on the small size for my hands and they're tight against my skin, there's no bagginess at all. Pretty much like a second skin, there's little to no chance of the material being able to bunch up. That just under 3 thou of thin latex like material is all the durability that these gloves are going to have.

They're not for keeping my hands warm; they'd be pointless for that.

Their only use is for keeping oils, cutting fluid and MEK off my skin (I also use Rozalex DryGuard barrier cream). If I'm working on brass, I generally don't bother wearing them.

Now, if I worked in a high school or college shop as an instructor, or I ran a workshop where there were likely to be young untrained people working, I'd be dogmatic and not allow any gloves but I'm in my own workshop on my own and I'm a reasonably intelligent person, with a fairly long career in the analysis of problems, specifically looking out for potential trouble down the track. I can keep to the essential spirit of the safety advice but not the letter of it.

This isn't a dig at you mate, I think you know the respect I hold for your skills and experience. Nobody, least of all me, would say you're ignorant of the underlying principles and just mindlessly parroting safety advice (leaving aside the fact that you're the kind of person who wants to know the whys and wherefores and understand things properly, you've seen these principles demonstrated, as per your pictures above and no doubt elsewhere besides).

However you are doing a very human thing, and it is based on a dogmatic approach, just in a different way. You're seeing what I'm saying only in terms of what you know of as 'gloves'; you're not allowing for the fact that in this case, the characteristics of gloves you're not particularly familiar with mean the risk that normally would be present are so reduced that they're negligible.

And of course, I hope you take my disagreement in the genuinely respectful and goodwill filled spirit it's meant. :)

You used all the words!!!

Neither you nor @pontiac428 could offend me, no worries there, we have always had good productive discussions even when we don't see eye to eye. And I know the exact type of nitrile gloves you speak of, I just prefer to not use any, and that will always be my recommendation.

Ive been in shops long enough to know the effects of the "Bad" stuff. Solvents that actually gave you a buzz simply through absorption through your skin, fun stuff like Trichlor, Tetrachloroethylene, Tywol (Xylene) and others, so wearing gloves as a barrier.....That ship has sailed for me and I wouldn't be surprised to wind up with a brain tumor some fine day.

Fun fact, I used to go race tether cars with my uncles who had Hydrazine in gallon jugs.

2nd fun fact, Dihydrogen monoxide is my favorite solvent and I've literally drank it by the gallon with mostly beneficial effects.

The part above in bold is how I see this entire forum. We have crusty old salts who know the risks and can pick and choose what they do personally, but there are also "Big ears in the cornfield" if you get the phrase.

As Charles mentioned, we don't want to set bad precedents to the "Green" guys and have them get hurt before they could even learn the whys and why nots.

What were doing here is productive and its the way these things should be discussed, and you would be surprised to find how often these discussions come up in an industrial setting.
 
Looks like a Kevlar cut resistant glove . They're my favorites for working out in the yard . My ex-company strictly encouraged all mechanics to take home what they wanted/needed as they needed us in at work . They didn't want us losing digits at home and missing work . :encourage: I still have a " couple " pairs in the 3 containers . :grin:

Those were the thinnest gloves we were allowed to have.

I like them tight so I can pick up tiny things while wearing them and have torn the backs out putting them on.



We got them for changing out the dies on the extruders . 650 degrees but no one ever used them . We had hot gloves and the older guys used them with no issues . The news guys saw this and figured they didn't need them either . :rolleyes: They dropped a lot of dies ! :grin:

Heh, picking up hot parts....


I mentioned complacency, but distractions, and just being lost in thought also come into play.

I've taken parts out of the tempering oven that were 1000f and tried to pic them up 5 min later as my mind was elsewhere.

Heat treat things long enough and your finger tips become numb. A party joke I used to play on friends was to pick up a hot coal out of the grill and hand it to them. Sometimes they would take it, sometimes I would be left holding it.

Like I said, chemicals that go through your skin.
 
Spaking of chemicals that go right through, the gloves you choose for the job matter. The breakthrough time is zero for buna-n/nitrile exam gloves with toluene, xylene, and especially ketones like MEK and acetone. If you put on a nitrile glove and spray paint your fingertips while holding a part, sure the pigment and heavier solvents like ethylbenzene stay on the surface of the glove, but the xylenes go right through and into your skin. PVA gloves (cheap food service disposables) do a good job of stopping those solvents.

Fun fact, toluene and xylene are ototoxins, they will make you go deaf from absorbing it through your skin.

I'd like to say that I'm so morally virtuous that's the reason why I avoid getting workshop chemicals on my hands but if I thought I could get high by touching one of them, I'd probably spend even more time in my workshop than I do! :grin:

(That's a joke BTW, there's a time and a place for getting high and that's not the workshop...it's in your late teens and early 20's when you're an annoying tosser at university of course!:grin:)

Actually the reason for avoiding getting chemicals on my hands is that my better half can't stand the slightest grime on my hands and keeping her happy is the reason for my investigation into 'fragile-enough-to-be-safe-but-decent-enough-barrier-for-long-enough-to-ensure-my-hands-are-clean-enough-after-a-post-workshop-scrub' gloves. I go through a lot of these gloves because of their fragility, but it's worth the hassle of putting on new gloves every half hour or hour to avoid the earache! :grin:

Yeah, good on a hot day, but personally I like a bit of 1,3,7-trimethylxanthine and some lactones and lipids dissolved in it. ;)

Yep, fair enough. I do always make sure I'm crystal clear about what kind of gloves I'm talking about and how fragile they are but you might have a point. I can't control how someone reads my posts or how much they read (although I can't imagine anyone not reading all of my profound thoughts :cool::grin:) so maybe you have a point. Maybe I should zip it.

I can imagine. We saw some quite heated discussions about the subject in the canteen at the Cosworth facility. Obviously being in England, it was generally disagreement between those who would insist on wearing their bowler hats, and those who claimed a flat cap was the correct, safe headwear.

:grin:

Yeah, to be fair it seems I can feel MEK starting to chill my fingers pretty quickly after it gets on the gloves and the fingertips pretty quickly disintegrate.

I figured the MEK was attacking the gloves and breaking them down pretty quickly and getting through the damage but you're saying it's just immediately getting straight through.

I try to avoid getting MEK on my hands (to avoid chucking away even more pairs of gloves than I do already) but it sounds like I should be even more careful.

How bad is it to get MEK on my skin? I mean I'm not wallowing in the stuff but I do occasionally get a little on my hands.
 
Worst chemical incident I ever had was with Tywol.

At my press station at this job I used sheets of cardboard stacked up with a hole cut in them to hold a spray paint lid, and put the tywol in this to dip the shafts of parts (Automotive water pumps) in before pressing them onto/into the fan hub.

This layered cardboard would soak up the tywol and one day if a fit, I smashed my hammer down onto the soaked cardboard and the resulting spray went right into my eyes even with glasses on.

I was immediately blinded, well I didn't lose my sight, but lets just suffice it to say opening my eyes felt like having a thousand needles jabbed into them.

This was on a Saturday and there were maybe 5 people in the whole place so there was no help available. I had to stagger and bump my way through a maze of 55gal drums that held the in process parts. Imagine an ever shifting walkway through a sea of drums that changed by the minute when people were taking or leaving finished parts. No way to memorize a path at all, IO just had to bump my way through.

Oh, and the drums were torn and sharp in most cases.

I finally made my way to the tool crib where the eyewash station was and only then did I get help. Eyewash plus a ride to the clinic.

The job I had prior to that was pressure treating lumber with a cyanide Arsenic based solution that turned your skin a greenish orange.

The staples/tags? I put on hundreds of thousands of them with the wood still dripping wet.

Try this to see how fast it penetrates the gloves- inflate one like a balloon, maybe the size of a cantaloupe, then drip one drop of MEK on the balloon and watch what happens. It's instant. Same with toluene. It's a reasonable way to test something, different chemicals have varying breakthrough rates, it all depends on the molecular structure and how it relates to the barrier material.

@RaisedByWolves, that must have been an unfun experience with the toluol, but those pressure treat chemicals are cancer, even after they got rid of the organic metallic salts and switched to chlorinated organic salts. Even the organic copper and tin is bad news. Pressure treat is important for preserving wood in contact with the ground or concrete, but those who work with it at the factory are a high risk group for adverse health outcomes. That's a spooky job among spooky jobs, so keep an eye out.
 
There is always the confidence that two faces are clean once your hand has passed over them, there is nothing better than skin.
Putting things on a magnetic chuck on a surface grinder after a wipe with plastic gloves, nah.

Yep, that is a good point and a downside to wearing the nitrile gloves I do.

That said, their fragile nature often means that you end up with a digit or two easily exposed and frankly, taking them off, feeling the part and then sticking another pair on, if required is no great burden either in time or money (they're not expensive).

All that said, all this talking about chucking multiple pairs of gloves over a two or three hour period in the bin as I do, in this thread is starting to make me feel a bit guilty about my 'plastics footprint'. :oops:

Maybe, when I've used up these last three boxes of gloves (and that won't take that long), I won't order any more.

I've recently been applying a fair bit more Rozalex DryGuard to my hands, and I've noticed it does make getting the grime off a fair bit easier after a workshop session; as long as it's all absorbed, more is definitely more with DryGuard. ;)
 
I have a Lexan gaurd I use on the mill for flying chips, helps with cleanup also.

I also wear long sleeve shirts when it cold.
