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

The most severe health hazards associated with Silica Gel are listed since the exact form of Silica contained in this product is unknown.

Inhalation:
Irritation of upper respiratory tract, excessive inhalation may cause lung damage, pneumoconiosis, silicosis, cyanosis, coughing, difficult breathing.

Ingestion:
None identified.

Skin Contact:
Irritation.

Eye Contact:
Irritation.

Chronic Exposure:
Lung damage, congestion of heart, liver, kidneys, and spleen, alters blood composition.

Aggravation of Pre-existing Conditions:
Respiratory system disease.


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:
None identified.

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 suitable protective clothing. Carefully sweep up and remove. Vacuuming or wet sweeping may be used to avoid dust dispersal.


7. Handling and Storage

Keep container tightly closed. Store in a cool, dry, well-ventilated area away from moisture. 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): 6 mg/m3 (TWA) PEL is for Silica, amorphous, precipitated and gel. -ACGIH Threshold Limit Value (TLV): 10 mg/m3 (TWA) TLV is for Silica - Amorphous, Silica gel.

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 protective gloves and clean body-covering clothing.

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.
