Potential Health Effects

----------------------------------

Inhalation:

Not expected to be a health hazard.

Ingestion:

Mildly toxic by ingestion. Systemic toxicity is unlikely unless massive amounts have been swallowed. Drinking

water with > 500 mg/L may result in gastrointestinal irritation.

 

Skin Contact:

No adverse effects expected.

Eye Contact:

No adverse effects expected but dust may cause mechanical irritation.

Chronic Exposure:

No information found.

Aggravation of Pre-existing Conditions:

No information found.

--------------------------------------------------------------------------------

4. First Aid Measures

Inhalation:

Not expected to require first aid measures.

Ingestion:

Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical advice.

Skin Contact:

Wash exposed area with soap and water. Get medical advice if irritation develops.

Eye Contact:

Wash thoroughly with running water. Get medical advice if irritation develops.

--------------------------------------------------------------------------------

5. Fire Fighting Measures

Fire:

Not considered to be a fire hazard.

Explosion:

Not considered an explosion hazard, but violent explosions occur when potassium sulfate and sodium sulfate are

melted with aluminum.

Fire Extinguishing Media:

Use any means suitable for extinguishing surrounding fire.

Special Information:

Use protective clothing and breathing equipment appropriate for the surrounding fire.

--------------------------------------------------------------------------------

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. 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.

Skin Contact:

No adverse effects expected.

Eye Contact:

No adverse effects expected but dust may cause mechanical irritation.

Chronic Exposure:

No information found.

Aggravation of Pre-existing Conditions:

No information found.
