Section 3. Hazard Identification

Emergency Overview: May cause eye and skin irritation. May cause digestive tract irritation.

            Wash areas of contact with plenty of water.

Target Organs: None known.

Skin/eye Contact: May cause slight irritation, redness, and pain.

Inhalation: Not expected to be a health hazard.

Ingestion: Mildly toxic. May cause throat irritation.



Section 4. First Aid Measures

Inhalation: Remove to fresh air.

Skin/eye Contact: Remove contaminated shoes and clothing. Flush contaminated area with

            plenty of water for at least 15 minutes. Call a physician if irritation develops.

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

            advice.



Section 5. Fire Fighting Measures

Fire & Explosion hazards: Not considered to be a fire or explosion hazard. Sodium sulfate powder

            can create a violent explosion when combined with Aluminum or Magnesium at 800?   C

            (1472?F).

Extinguishing Media: Use any means suitable for extinguishing surrounding fire.

Specific Methods: Firefighters should wear proper protective equipment and breathing apparatus for

            surrounding fire.



 Section 6. Accidental Release Measures

Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in

Section 8. Dilute with water and mop up or absorb spills with absorbent (vermiculite, sand, fuller's

earth) and place in plastic bags for later disposal. Always dispose of in accordance with local

regulations.
