I'm sure they think the local version of osha is more of a suggestion.

DemeaninDemon posted:Dumb engineers. What the gently caress? Does he have no idea how that thing actually works? Best case scenario, this burns out the RF generator and costs $10k+ to fix, right? I would offer to run his dumb thing through the machine, but properly prepare the sample first by dissolving it in an appropriate acid solution. Return him the spectrographic analysis and call it a day. For everyone else: an ICP-OES is an inductively coupled plasma optical emission spectrometer. The "torch" is made by pumping argon through a quartz tube and creating an arc through it with a high voltage. The resulting plasma is then fed by a helical RF coil surrounding the tube, which basically turns the tube into a cylindrical microwave oven. The argon plasma inside the tube is hilariously hot, which owns. To do the actual spectroscopy part, you feed a dilute sample contained in an aqueous or organic solution, which is fed via peristalsis pump into a nebulizer that injects a fine spray of it into the plasma torch. The heat of the plasma breaks a lot of those dumb molecular bonds, and causes the constituent atoms to shine in their respective energy spectra. There is a spectrometer pointed at the torch, which captures the emitted light and determines its energy spectrum, and by comparing it to the spectrum of a reference sample you can determine the atomic composition of your sample.

TheWhiteNightmare posted:What does it do to bone We could find out but, as pointed out, we'd have to prepare the bone for analysis in an appropriate solvent. I suggest dissolving it in HF. The thing probably wouldn't even stay lit long enough to toss something in it, sadly. Not to mention the safety switch on the door that turns it off.

Induced a pretty dumbass OSHA moment this evening… Drove my GF home and saw that her father’s car was stuck in the snowbank in the front of the driveway (I think he got a bit too lazy to shovel and figured he could just force the car in). I have a set of something called traction aids in my car which are metal crampons you put behind or in front the wheels to help the car get traction when it’s stuck. As the driveway is full of snow, her father is trying to back the car out - As such I place the traction aids in back of the front wheels (front wheel drive car with no limited slip differential). I try my best to ensure that the crampons are placed firmly in the snow / ice and proceed to push the front of the car to help it out. Her father doesn’t exactly feather the gas, and one of the crampons ends up becoming a projectile flying towards me at a pretty significant velocity landing 30 feet away. That crampon weighs approximately 5 pounds and grazes my thigh a few inches above the knee. No major damage other than ripped pants, some cuts and a solid bruise but I’m thinking this could easily shatter some bones / knee caps if it hits someone with full impact. Stupid and careless moment on my part, but I’ve never had them move out more than a foot or two before (nor been stupid enough to stand in the line of sight...).

I suggest dissolving it in HF. i mean, probably could if you set it up before starting the torch. You could attach the (small) sample to the end of the injector, but it would break off once the torch destroyed whatever was holding it to the injector. You could also just toss it in the tube itself, but that might shatter the tube, since that would create a hotspot on the inner surface.

That's a stupid qualifier. The sun's surface is only ~6,000C, but the sun is ~15,000,000C at its core and ~1,000,000C+ in its corona (which surrounds the sun and extends millions of km into space). The sun's surface is the coolest part of or anywhere around the sun by orders of magnitude. To imply that the torch comes anywhere close to the heat of the sun just to get people to go "wow that's hot!!!" is pretty misleading imo.

We have these face shields at work.  The dumb thing covers my chin but not neck. The gown also leaves the neck open. Yeah I'm sticking to the standard pull down face shield for reagents that want to kill me OK thanks. Though it's cool being Darth Quimicius.

My favorite part is that all of them (even the little girl) realize what's about to happen and run....except for that one chick, who has to turn a full 360 degrees wondering where everyone's gone before following them.

i get to drive our yards big diesel powered forklift around the yard with no real formal training. I'm also an operator so I'm expected to know how to use it. I don't really use it much unless we need to load a skid of bentonite (sorta as hazardous as asbestos, silicate crystals) or lifting big reamers out the back of our chase truck. fork lift drivers that work in factories and poo poo though are crazy. i know they want maximum productivity but most of the time I see them theyre in such a god drat rush its probably dangerous

Yeah, at the training institute I work at our books on overhead cranes and forklifts emphasize that one of the reasons they're so dangerous is because their simplicity encourages business owners to put untrained or informally trained operators ("Just hit this lever to hoist it up, call me if you can't figure it out" on his first day of work) to work on the machines, and then inevitably the completely clueless forklift driver or crane operator gets the blame when they drop something.
