Potential Health Effects
----------------------------------
Inhalation:
May cause irritation to the respiratory tract.
Symptoms may include coughing, sore throat, labored breathing, and chest pain.
Ingestion:
Large doses may produce abdominal pain, nausea, and
vomiting.
Skin Contact:
May cause irritation with redness and
pain.
Eye Contact:
Contact may cause 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:
Immediately flush skin with plenty of
water for at least 15 minutes. Remove contaminated clothing and shoes. Wash
clothing before reuse. Thoroughly clean shoes before reuse. Get medical
attention if irritation develops.
Eye Contact:
Immediately
flush eyes with plenty of water for at least 15 minutes, lifting upper and
lower eyelids occasionally. Get medical attention if irritation persists.
5. Fire Fighting Measures
Fire:
Autoignition temperature: 611C (1132F)
As with
most organic solids, fire is possible at elevated temperatures or by contact
with an ignition source. Listed fire data is for the Anhydrous Material.
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
Remove all sources of ignition. Ventilate area of leak or spill.
Wear appropriate personal protective equipment as specified in Section 8.
Spills: Clean up spills in a manner that does not disperse dust into the air.
Use non-sparking tools and equipment. Reduce airborne dust and prevent
scattering by moistening with water. Pick up spill for recovery or disposal
and place in a closed container. 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. Isolate from any source of
heat or ignition. 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:
- OSHA Permissible Exposure
Limit (PEL):
15 mg/m3 total dust, 5 mg/m3 respirable fraction for nuisance
dusts.
- ACGIH Threshold Limit Value (TLV):
10 mg/m3 total dust
containing no asbestos and < 1% crystalline silica for Particulates Not
Otherwise Classified (PNOC).
Ventilation System:
A system of
local and/or general exhaust is recommended to keep employee exposures below
the Airborne Exposure Limits. 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):
If the exposure limit is exceeded, a half-face
dust/mist respirator may be worn for up to ten times the exposure limit or the
maximum use concentration specified by the appropriate regulatory agency or
respirator supplier, whichever is lowest. A full-face piece dust/mist
respirator may be worn up to 50 times the exposure limit, or the maximum use
concentration specified by the appropriate regulatory agency, or respirator
supplier, whichever is lowest. For emergencies or instances where the exposure
levels are not known, use a full-facepiece 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.
