Potential
Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include
coughing, shortness of breath.
Ingestion:
Causes irritation to the gastrointestinal tract. Symptoms may
include nausea, vomiting and diarrhea. Extremely large oral dosages
may produce gastrointestinal disturbances. Calcium deficiency
in blood may result in severe cases of ingestion.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching,
and pain.
Eye Contact:
Highly irritating; may also be abrasive.
Chronic Exposure:
Chronic or heavy acute ingestion may cause tooth enamel erosion.
Aggravation of Pre-existing Conditions:
No adverse health effects expected.
--------------------------------------------------------------------------------
4.
First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, give oxygen. Get medical attention.
Ingestion:
Induce vomiting immediately as directed by medical personnel.
Never give anything by mouth to an unconscious person. Get medical
attention.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes.
Remove contaminated clothing and shoes. Get medical attention.
Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes,
lifting lower and upper eyelids occasionally. Get medical attention
immediately.
--------------------------------------------------------------------------------
5.
Fire Fighting Measures
Fire:
Autoignition temperature: 1011C (1852F)
As with most organic solids, fire is possible at elevated temperatures
or by contact with an ignition source.
Explosion:
Fine dust dispersed in air in sufficient concentrations, and in
the presence of an ignition source is a potential dust explosion
hazard.
Fire Extinguishing Media:
Water spray, dry chemical, alcohol foam, or carbon dioxide.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated
in the pressure demand or other positive pressure mode.
--------------------------------------------------------------------------------
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
--------------------------------------------------------------------------------
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:
A system of local and/or general exhaust is recommended to keep
employee exposures as low as possible. Local exhaust ventilation
is generally preferred because it can control the emissions of
the contaminant at its source, preventing dispersion of it into
the general work area. Please refer to the ACGIH document, Industrial
Ventilation, A Manual of Recommended Practices, most recent edition,
for details.
Personal Respirators (NIOSH Approved):
For conditions of use where exposure to dust or mist is apparent
and engineering controls are not feasible, a particulate respirator
(NIOSH type N95 or better filters) may be worn. If oil particles
(e.g. lubricants, cutting fluids, glycerine, etc.) are present,
use a NIOSH type R or P filter. 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 impervious protective clothing, including boots, gloves,
lab coat, apron or coveralls, as appropriate, to prevent skin
contact.
Eye Protection:
Use chemical safety goggles and/or full face shield where dusting
or splashing of solutions is possible. Maintain eye wash fountain
and quick-drench facilities in work area.
