It is a sad state of affairs when MSDS sheets do nothing but remind
us of the fable of the boy who cried wolf. IMHO, the safety industry
nothing but a clever scheme by the 'C' students of the world to take
control. :-)

 Kelly,

Compare the write ups for something you have had experience
with. I got a warning with some sodium chloride we got from a chemical
supply house that warned to use only with goggles and a face mask to protect
against dust. Think of that when you salt your eggs in the morning. The
MSDS is used to protect against any liability, and in my humble opinion
is often over kill.

Hi Jerry,

Thanks for your reply!

Yep, I checked the MSDS.  It does have the most comprehensive safety
information on substances, which raises a good question I've long had about
how to read and use the information in the MSDS.  Because it is complete,
reading an MSDS is often like reading the side-effects of a medication. 
For example, read the side effects of aspirin, and you might think it a
quite dangerous substance, yet we know that it is relatively safe for most
people.  Analogously on the MSDS, consider the following potential
health effects listed for copper:

INHALATION: SHORT TERM EXPOSURE: irritation, metal fume fever

LONG TERM EXPOSURE: metallic taste

SKIN CONTACT: SHORT TERM EXPOSURE: irritation

LONG TERM EXPOSURE: no information on significant adverse effects

EYE CONTACT: SHORT TERM EXPOSURE: irritation, tearing, blurred vision

LONG TERM EXPOSURE: same as effects reported in short term exposure

INGESTION: SHORT TERM EXPOSURE: nausea, vomiting, diarrhea, headache

LONG TERM EXPOSURE: no information on significant adverse effects

Certainly somebody has had these health effects after handling a piece
of copper, but I suspect they are rare.  So, any words of advice on
reading and using the information in the MSDS in general?

Also interesting: there are three references given on all MSDS for Carcinogen
Status: OSHA, NTP, IARC.  Anybody know why?

For Nickel, OSHA says it is not a carcinogen, but NTP and IARC say it
is.

An MSDS has the most comprehensive safety information on a given substance
that I know of.  Maybe your campus safety people could help too...

Hi Everybody,

I'm doing a little background work on my niece's proposed science fair
project - that is, checking the safety issues of the supplies she's requested. 
I thought you all might be able to help me out on this:

She needs a small amount of nickel powder or nickel shot to mix with
soil in which she will be growing plants.

Sites like the Los Alamos Periodic Table say:

Nickel is recognized as being potentially carcinogenic.

"Exposure to nickel metal and soluble compounds (as Ni) should not
exceed 0.05 mg/cm3 (8-hour time-weighted average -
40-hour work week)."

Yet, k-12 science suppliers sell nickel shot and powder, and label it
non-hazardous.

Does anybody know, is handling nickel powder or shot dangerous? 
What are the dangers here?

Thanks for any advice you can send my way - it will help me earn my
good-aunt merit badge!
