Potential Health Effects
----------------------------------

Inhalation:
Irritation of upper respiratory tract, irritation of mucous membranes.

Ingestion:
Nausea, vomiting, diarrhea.

Skin Contact:
Irritation.

Eye Contact:
Irritation.

Chronic Exposure:
Bladder, central nervous system depression.

Aggravation of Pre-existing Conditions:
No information found.


4. First Aid Measures

Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Prompt action is essential.

Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention.

Skin Contact:
In case of contact, flush skin with water.

Eye Contact:
In case of eye contact, immediately flush with plenty of water for at least 15 minutes.


5. Fire Fighting Measures

Fire:
Not expected to be a fire hazard.

Explosion:
Strong oxidizer. Contact with combustible materials, flammable materials, or powdered metals can cause fire or explosion.

Fire Extinguishing Media:
Use extinguishing media appropriate for surrounding fire.

Special Information:
Firefighters should wear proper protective equipment and self-contained breathing apparatus with full facepiece operated in positive pressure mode. Flood with water spray to prevent splashing of material.


6. Accidental Release Measures

Wear suitable protective clothing. Stop leak if you can do so without risk. Keep combustibles (wood, paper, oil, etc.) away from spilled material. Take up with sand or other non-combustible absorbent material and place into container for later disposal. Flush spill area with water.


7. Handling and Storage

Powdered material may form explosive dust-air mixtures. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); 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 substance is apparent, consult an industrial hygienist. 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 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 a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.
