Potential Health Effects
----------------------------------
This compound resembles phenol in its systemic actions, but is less toxic
because it is almost insoluble.
Inhalation:
May cause irritation to the respiratory tract. Symptoms may include
coughing and shortness of breath. May be absorbed into the bloodstream with
symptoms similar to ingestion.
Ingestion:
Produces abdominal pain, nausea, vomiting, central hyperactivity (e.g.,
talkativeness), and occasionally convulsions, coma and cardiac and
respiratory collapse. Oils and alcohols may promote absorption into the
body. May cause kidney and liver damage.
Skin Contact:
May cause irritation with redness and pain.
Eye 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. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention.
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.
Explosion:
Not an explosion hazard under normal conditions of storage and use, but
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.
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. Keep
unnecessary and unprotected people away from area of spill. Wear
appropriate personal protective equipment as specified in Section 8.
Spills: Pick up and place in a suitable container for reclamation or
disposal, using a method that does not generate dust.
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. Isolate from incompatible substances. 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,ent 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.
