IRRITATION TO SKIN, EYES, AND RESPIRATORY TRACT.
Potential Health Effects
----------------------------------
The toxicological properties of this material have not been investigated.
Inhalation:
No information found, but compound should be handled as a potential health
hazard. May cause irritation to the respiratory tract. Symptoms may include
coughing, sore throat, labored breathing, and chest pain.
Ingestion:
No information found, but compound should be handled as a potential health
hazard. May cause irritation to the gastrointestinal tract. Symptoms may
include nausea, vomiting and diarrhea.
Skin Contact:
No information found, but compound should be handled as a potential health
hazard. May cause irritation with redness and pain. May be absorbed through
the skin with possible systemic effects.
Eye Contact:
No information found, but compound should be handled as a potential health
hazard. 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 while
removing contaminated clothing and shoes. Wash clothing before reuse.
Thoroughly clean shoes before reuse. Get medical attention if symptoms
occur.
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:
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:
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 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.
Other Control Measures:
There is insufficient data in the published literature to assign complete
numerical SAF-T-DATA* ratings and laboratory protective equipment for this
product. Special precautions must be used in storage, use and handling.
Protective equipment for laboratory bench use should be chosen using
professional judgment based on the size and type of reaction or test to be
conducted and the available ventilation, with overriding consideration to
minimize contact with the chemical.
