|
| 3. Hazards Identification |
|
Routes of entry: respiration,
eyes, skin contact
Carcinogenicity: none
Target organs: eyes, lungs
Health impact on eye: Direct contact
of the eyes with its dust might
cause mechanical irritation.
Health impact on skin: Direct
contact of the skin with its dust
might cause slight skin dryness
and slight irritation.
Health impact on digestive system:
Inhalation of fine bentonite dust
might cause mechanical irritation
to the nose and throat.. |
|
| 4. First-aid Measures |
|
Eyes: Flush the eyes with plenty
of water or 0.6% saline solution.
If irritation or reddish swelling
persists, see a doctor.
Skin: An ordinary emollient may
eliminate dryness. If irritation
or reddish swelling persists,
see a doctor. In case of a bruise,
clean the wound with dilute suds.
Digestive system: Since this material
is not absorbed in the digestive
system, it is thought as nontoxic
to the body.
Respiratory system: If this occurs,
move to fresh air immediately.
In case of stop of respiration,
take an artificial respiration
and send the patient to the hospital
immediately. Keep warm and have
enough rest.
Emergency eye washing: If employees
are likely to be exposed to high
concentrations of air-borne dust,
the employer shall provide a water
source nearby to provide against
accidents. |
|
| 5. Fire Fighting Measures |
|
Extinguishing medium: A nonflammable
medium should be used. The medium
selected should not react with
the other components of the product.
Warning on special production

of dust
Fire fighting protection equipment:
no special requirement |
|
| 6. Accidental Release Measures |
|
| Overflow process: no special measure
needed |
|
| 7. Handing and Storage |
|
Handing: This product should be

the dust concentration of the
workshop, which shall not exceed
the normal working range of the
mask.
Hand protection: Protective gloves
are usually not necessary. However,
if there is a need, they can be
used to prevent skin drying and
irritation.
Eye protection: dustproof goggles
Body protection: common working
clothes
Emergency eye washing: If employees
are likely to be exposed to high
concentrations of air-borne dust,
the employer shall provide a water
source nearby to provide against
accidents. |
