Toxicological Data on Ingredients:  Not applicable.

 

Section 3: Hazards Identification

 

Potential Acute Health Effects: Slightly hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation.

 

Potential Chronic Health Effects:

CARCINOGENIC EFFECTS: Not available.

MUTAGENIC EFFECTS: Not available.

TERATOGENIC EFFECTS: Not available.

DEVELOPMENTAL TOXICITY: Not available.

The substance may be toxic to lungs, upper respiratory tract.

Repeated or prolonged exposure to the substance can produce target organs damage.

 

Section 4: First Aid Measures

 

Eye Contact:

Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used. WARM water MUST be used. Get medical attention if irritation occurs.

 

Skin Contact: Wash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation develops.

 

Serious Skin Contact: Not available.

 

Inhalation:

If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.

 

Serious Inhalation: Not available.

 

Ingestion:

Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight clothing such as a collar, tie, belt or waistband.

 

Serious Ingestion: Not available.

 

Section 5: Fire and Explosion Data

 

Flammability of the Product: Non-flammable.

 

Auto-Ignition Temperature: Not applicable.

 

Flash Points: Not applicable.

 

Flammable Limits: Not applicable.

 

Products of Combustion: Not available.

 

Fire Hazards in Presence of Various Substances: Not applicable.

 

Explosion Hazards in Presence of Various Substances:

Risks of explosion of the product in presence of mechanical impact: Not available.

Risks of explosion of the product in presence of static discharge: Not available.

Slightly explosive in presence of heat.

 

Fire Fighting Media and Instructions: Not applicable.

 

Special Remarks on Fire Hazards:

Calcium Sulfate mixed with phosphorus will ignite at high temperatures.

When primed at high temperature with potassium nitrate-calcium silicide mixture, calcium sulfate mixed with excess red phosphorus will burn.

 

Special Remarks on Explosion Hazards:

Contact with diazomethane causes an exothermic reaction which may lead to detonation.

Many metal oxo-compounds (nitrates, oxides, and particulary sulfates) and sulfides are reduced violently or explosively (undergo a thermite reaction) on heating an intimate mixture with aluminum powder to a suitably high temperture to initiate the reaction. A violent or explosive reaction can occur upon heating when calcium sulfate is mixed with aluminum powder.

Containers may explode when heated.

 

Section 6: Accidental Release Measures

 

Small Spill:

Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.

 

Large Spill:

Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities.

 

Section 7: Handling and Storage

 

Precautions: Do not breathe dust. Keep away from incompatibles such as oxidizing agents, acids.

 

Storage: Keep container tightly closed. Keep container in a cool, well-ventilated area. Hygroscopic

 

Section 8: Exposure Controls/Personal Protection

 

Engineering Controls:

Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.

 

Personal Protection: Safety glasses. Lab coat. Gloves (impervious).

 

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.
