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

Inhalation:
Irritation of upper respiratory tract.

Ingestion:
Ingestion of large quantities may be fatal.

Skin Contact:
Severe irritation or burns, May be absorbed through the skin with possible systemic effects.

Eye Contact:
Severe irritation or burns.

Chronic Exposure:
Kidney damage, liver damage.

Aggravation of Pre-existing Conditions:
Damaged skin.


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, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before re-use.

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:
No information found.

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.


6. Accidental Release Measures

Wear self-contained breathing apparatus and full protective clothing. With clean shovel, carefully place material into clean, dry container and cover; remove from area. Flush spill area with water.


7. Handling and Storage

Keep container tightly closed. Store in secure poison area. Material is hygroscopic. 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 (TWA) The PEL for Boric Anhydride is listed under Boron oxide. -ACGIH Threshold Limit Value (TLV): 10 mg/m3 (TWA) The TLV for Boric Anhydride is listed under Boron oxide.

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 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 full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
