Lab Best Practice

[snoman701]

You can say what you want, or ignore what you want. The reality is that if people spent less time watching YouTube videos and more time in the crc handbook as well as reading the material safety data, and utilizing that information to choose situationally appropriate personal protective equipment, the danger wouldn't exist.

I used to routinely work around unpredictable patients infected with biosafety level three pathogens. If you think I utilize unsafe practices, you'd be dead wrong. I attempt to learn the dangers of everything I do before I do it.

It's not about coming up with new laboratory practices. It's about learning what is an acceptable practice and actually practicing it....not just talking about it.

Thinking about how to improve a process does nothing. Practicing it does. Observing other professionals does.

This whole thread is you saying the same thing over and over again, while seasoned members simply tell you to practice proven situationally appropriate hazard protection.

Practice...not think about, practice.

Despite suggestions to stop bothering, here goes ...

Dunking body parts into acids is not a Good plan, coated with rubber or otherwise.

Would you do that to de-rust a saw blade ?

Personally i'd dunk it in phosphoric acid, wait a while then rinse in a load of tap water, dunk & rinse using a bit of wire to handle it.

At no point would i put on a condom and try to whiz it up with my ****.
Not got a saw that small anyway.

There really is No Need to risk exposing your body to the chemicals you use. None.

Stand back and think about what you do, maybe you'll see what i mean, maybe not.

The Aim is to extract the values over and over again, right ?

If you never ever come in contact with the chemicals - neither the reagents nor the interim products - you'll live longer and extract more values.

If i'm wrong about that, i'm a dog barking up entirely the wrong tree.

I think aga's "best lab practice" is based on foolishness, fear, and paranoia. Gloves are made to get chemicals on them, period. But, to each their own. I've had a lot of people working for me over the years. I never hired people that were afraid of the chemicals or, usually, those that were color blind. The ones that were afraid of the chemicals were very, very dangerous to be around.

Would you mind explaining your reasoning behind that statement ?

From my not-a-professional-refiner point of view ...

Foolishness:-
taking unnecessary risks.
wasting gloves.
losing values all over the gloves.
losing time due to glove changing
adding water due to glove-washing
wasting time evaporating water that did not need to be there in the first place

Fear:-
a worker scarred for life due to leaky gloves, even though they punctured them.
being sued by the same worker, and they win
knowledge of what these chemicals can do to a body. (More Respect for them rather than simple fear)

Paranoia:-
this is a Positive thing. Humans are weak and fickle. We take dangerous short-cuts if not thinking of the consequences.

Gloves are meant to protect hands. Another period.
Gloves are not magic force-fields that make everything OK. Multiple periods.

Seriously, if you're having to paddle around in your acids, surely you can think of ways to avoid that being necessary ? Again, only you know exactly what you do, so it's entirely up to you.

"Kaizen" is what Japanese industry does. It means "Continuous Improvement".
Every day they spend a few moments thinking about how to improve things, if even in a very small way.

The Chemistry in refining is already 99.9999% done, so what else could be improved ? Nothing at all ?

Respect - having an understanding of what will happen if something goes wrong.

Fear - an irrational emotion based upon a lack of understanding of cause and effect.

I have a serious respect for concentrated sulfuric acid. I know what will happen if I get it on my hand. I wear appropriate ppe when handling it.

I have a serious fear of snakes. I no longer make rational, thought out and calculated decisions. I am a liability to any dangerous situation in which a snake must be handled carefully as I am completely distracted by my fear.

With appropriate training and exposure to different situations, one develops confidence and can navigate through situations that they'd never think possible. When the emotion of fear takes over, one freezes.

Please tell us what you Know happens when 98% sulphuric acid gets on your hand.

Acids are most dangerous if your skin is made of copper. :lol:
The thing that i work with, as far as skin goes, that scares me the most is hot Sodium Hydroxide!
I ALWAYS wear eye protection!

I always think of Fried Green Tomatoes when I think of hot lye. For those that don't remember, Frank Bennet gets served up for dinner to the sheriff, with it insinuated that his remains were then rendered in to soap.

Powerful stuff.

Now bbq sounds good. Thanks Palladium.
