Potential Health Effects
----------------------------------
Inhalation:
May cause irritation to the respiratory tract. Symptoms may include coughing,
sore throat, labored breathing, and chest pain.
Ingestion:
Large oral doses may cause irritation to the gastrointestinal tract. Ingestion
may cause intestinal obstruction.
Skin Contact:
May cause irritation with redness and pain.
Eye Contact:
May cause irritation, redness and pain.
Chronic Exposure:
No adverse health effects expected.
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 large amounts of water to drink. 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. 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:
As with most organic solids, fire is possible at elevated temperatures or by
contact with an ignition source. Melted fatty acid can give "grease"
type fire.
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:
Dry chemical, foam or carbon dioxide. Pressure from the extinguishing media
may cause severe dusting. Do not use heavy streams of water, molten
material will float on water.
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.
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:
- 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):
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.
