Dangers of machining carbon-fiber?

Reminds me of when I worked in a pre-sintered carbide shop. It was so dusty and dirty you needed to wear a Haz-Mat suit and a respirator. Every 3 months they'd bring in a Dr. to examine your lungs and the first thing out of his mouth after he checked you was he'd wish you'd stop smoking. Didn't make a difference if you smoked or not, the diagnosis was the same.
My father-in-law lived all his life in the East Midlands in the UK. He told me that when he was young the doctors recommended smoking cigarettes to coal miners because the hacking and coughing would cough up the coal dust from their lungs.
 
I did not see that in the MSDS where did you find DMHO in the product sheets.
Try and keep up here, Dihydrogen Monoxide is in almost every product that you have ever used, it is deadly and should be banned from all consumer goods.

Dihydrogen monoxide, H2O, otherwise known as water.

Was wondering when someone would get around to that reality:
Di = 2 (x hydrogen)
Mon - 1 (x oxygen)
Or:
H20... = water

Sorry... that site must be a hoax.
Or a goof that is afraid of their shadow.

I think it is actually meant to be satire. The point was to show how ridiculous we can get about "chemicals". Everything on the site is true if you think about it. It's how you spin the truth that makes the difference.

In college, I had a chemistry professor that had previously taught at the Air Force Academy. They had a problem with ethyl alcohol disappearing. They relabeled it ethanol and the evaporation slowed but didn't stop so they relabeled it methyl carbinol and the evaporation stopped.

It just depends on the spin.
 
Your body is mostly made up of water and carbon (carbon based life form).
I could see the "Fiber" part possibly being an irritant to your lungs, but the only health hazard I can think of would be the other materials used in carbon fiber.

Yeah...
This reminds me of a video that circulated around the AC and refrigeration business years ago...
This intelligent looking (and attractive) lady was wandering around a public area asking folks to sign a petition to ban a refrigerant (freon) known as R-718... the video included about a half dozen folks that signed it.
Then the second half of the video she explained to each one of them (probably edited, the explanation happened with the signing)...
That R-718 was water... (true, R718 is water in a chiller).
Folks said it still should be banned because of the damage it did to the environment.

We have lost critical thinking...
However at this point I probably need to quit...
Because the discussion will go to politics...
Have a different forum for that... grin!

True that your body is made up of carbon but the way that carbon exists and what other atoms it is bound to make a big difference.
Example oxygen typically exists as O2 and is pretty safe to us (in fact you die without it) but O3 or ozone is nasty stuff and you really don't want to get anywhere near that.

Carbon fibre as we know it is more than just the carbon fibres, I believe it there are polymers that are used to bind the fibres.

After reviewing multiple MSD sheets, it appear that the dust from machining is about as harmful as walking down a dusty country road. It is considered a benign irritant, but poses no immediate or long term health hazard other than minor irritation. The primary binders for the carbon strands or weave are vinyl esters or epoxies. Any slivers that might become embedded in your skin would be similar to a metal or wood sliver.

As with working with any process which creates dust, it is always advisable to use personal protective equipment. However, in the context of the original post, I wouldn't be too concerned.
