Hi there,

I am back again about the Degussa stains. Went out into the garage
and dug out the Material Safety Sheets I received. I noticed one message
about this where the person "presumed" the materials were safe. NEVER
presume something is safe - research it and take care of yourself.

Some quotes from the data sheets.
"Hazard Statement: This product is considered to be a hazardous substance
under that standard (Federal OSHA Hazard Communication Standard 29
CFR 1910.1200).
The key Immediate Hazards are: - skin, eye and respiratory irritant.

Overexposure effects: Contains cadmium compounds. Overexposure to
cadmium by inhalation can result in a metallic taste in the mouth, headache,
shortness of breath, chest-pain, weakness, leg pains and fluid in the lungs.

These signs and symptoms may be delayed, sometimes occuring four to
eight hours follwing exposure. Kidney and liver damage may also occur.
Swallowing can result in severe nausea, vomiting, diarrhea, stomach cramps,
salivation, headache, muscle cramps and dizziness.

Long term overexposure to the fumes and dust of cadmium have been
associated with emphysema, bronchitis and kidney damage. Chronic
overexposure to the metal and cadmium compounds, such as cadmium
oxide, cadmium sulfide, cadmium sulfate and cadmium chloride, may
result in lung cancer,.....

Special Protection Information" (are you all still with me?????)

Emergency Phone: CHEMTREC 1-800-424-9300

I also want to mention one more thing. I got some of these stains from
a supplier here in Texas, and they did not send along any of the above
information. I also received several samples from Cerdec directly and
they mailed along the data sheets (10 pages on each stain!).

Anyway, I just had to add my two cents worth to this.. Let's take care
of our health! Learn to use chemicals safely.
