Potential Health Effects
----------------------------------
Inhalation:
High concentrations of dust may cause coughing
and sneezing.
Ingestion:
Extremely large oral doses may cause
gastrointestinal disturbances.
Skin Contact:
No adverse effects
expected.
Eye Contact:
Contact may cause mild irritation,
redness, and pain.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention
for any breathing difficulty.
Ingestion:
Give several glasses
of water to drink to dilute. If large amounts were swallowed, get medical
advice.
Skin Contact:
Not expected to require first aid
measures.
Eye Contact:
Wash thoroughly with running water. Get
medical advice if irritation develops.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire.
Special Information:
Use
protective clothing and breathing equipment appropriate for the surrounding
fire.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Sweep up and
containerize for reclamation or disposal. Vacuuming or wet sweeping may be
used to avoid dust dispersal. Small amounts of residue may be flushed to sewer
with plenty of water.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry,
ventilated area. Protect against physical damage. Containers of this material
may be hazardous when empty since they retain product residues (dust, solids);
observe all warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
None established.
Ventilation System:
In general, dilution ventilation is a
satisfactory health hazard control for this substance. However, if conditions
of use create discomfort to the worker, a local exhaust system should be
considered.
Personal Respirators (NIOSH Approved):
For
conditions of use where exposure to the dust or mist is apparent, a half-face
dust/mist respirator may be worn. For emergencies or instances where the
exposure levels are not known, use a full-face positive-pressure, air-supplied
respirator. WARNING: Air-purifying respirators do not protect workers in
oxygen-deficient atmospheres.
Skin Protection:
Wear protective
gloves and clean body-covering clothing.
Eye Protection:
Use
chemical safety goggles. Maintain eye wash fountain and quick-drench
facilities in work area.
