Section 6: Accidental Release Measures

 

Small Spill:

Dilute with water and mop up, or absorb with an inert dry material and place in an appropriate waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.

 

Large Spill:

Poisonous liquid.

Stop leak if without risk. Do not get water inside container. Do not touch spilled material. Use water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Call for assistance on disposal. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system.

 

Section 7: Handling and Storage

 

Precautions:

Keep locked up.. Do not ingest. Do not breathe gas/fumes/ vapor/spray. Avoid contact with eyes. Wear suitable protective clothing. If ingested, seek medical advice immediately and show the container or the label.

 

Storage: Keep container tightly closed. Keep container in a cool, well-ventilated area. Do not store above 24C (75.2F).

 

Section 8: Exposure Controls/Personal Protection

 

Engineering Controls:

Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their respective threshold limit value.

 

Personal Protection: Splash goggles. Lab coat.

 

Personal Protection in Case of a Large Spill:

Splash goggles. Full suit. Boots. Gloves. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.

 

Exposure Limits: Not available.

Section 10: Stability and Reactivity Data

 

Stability: The product is stable.

 

Instability Temperature: Not available.

 

Conditions of Instability: Incompatible materials

 

Incompatibility with various substances: Slightly reactive to reactive with oxidizing agents, metals.

 

Corrosivity: Non-corrosive in presence of glass.

 

Special Remarks on Reactivity:

Hygroscopic (moisture sensitive).

Sodium sulfate reacts violently with magnesium.

Also incompatible with aluminum, potassium mercury, lead, calcium, silver, barium, ammonium ions, and strontium.

Sulfates give precipitates with salts of lead, barium, strontium, and calcium. Silver and mercury form slightly soluble salts.Alcohol preciptates most sulfates out of solution. (Sodium sulfate anhydrous)

 

Special Remarks on Corrosivity:

The rates of corrosion of iron and steel in water are a function of the specific mineral quality as well as the alkalinity and pH values. Sodium sulfate ... is a strong contributor to the rate of corrosion. For example, in water with 400 mg/l of alkalinity (as CaCO3) at pH 7, the corrosion rate will be zero at 200 mg/l of Na2SO4, but when the concentration of sodium sulfate is 400 mg/l, the corrosion rate will be about 100 mg per square cm per day.
