Titanium and niobium dust - toxic?


#1

When hand-working titanium and niobium sheet using emery paper dry
and working about 9" from (unmasked) face, are the resultant fine
particles (metal dust) toxic to inhale or ingest in any other way?

You can bet they aren’t doing you any good, Suzi!

he only answer that is suitable in today’s libel laced world is when
in doubt cover up. Everything in our atmospere is toxic. Is it more
toxic then silver or gold? Microscopic metals will remain in your
longs. Nothing there is strong enough to dissolve them.

How long is apiece of string/ or dont wak under ladders! Any dust or
fumes in large regular amounts will be bad for you.

Find a way to not inhale it.

titanium is a reactive/ getter metal, ie its very difficult to
remove its oxide layer. so even the smallest particles will be
covered in its oxide.

this non reactive coating is one of the reasons its used in medical
plates and pins in orthopedic repair work.

theres a certin particle size of any dust thats particularly
dangerous. its the same size as the internal diaof the smallest air
ducts in your lungs. this size doesnt get breathed out it sticks in
the tubules, smaller particles get breathed out, larger dont get that
far.

also it will depend on the general ventilation of your workshop.

I use a proper industrial vac system for all my polishing, linishing
and finishing setups. Aim for at least 600 cft a min air flow.

it’s never a good idea to inhale dust in any kind. Once in your
lungs, it can’t get out.

Hi

I treat all sanding dust as toxic and use a vacuum cleaner with a
water filter to collect particulate matter.

For my buffer I use a shop vac with bag and a particulate mask.

Niobium MSDS can be found at:

Titanium MSDS can be found at:
http://www.ganoksin.com/gnkurl/ep80bs

MSDS = Material Safety Data Sheet

These are provided by the companies that supply these metals, they
list hazards and safety precautions for the metals.

optimally you should never breath any dust from anything, not rubber
wheels, not compound, not fume, nothing, and if you would rather
not wear a mask then you must have dust collection between the work
and your face, here is a google about titanium and lung effects
