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. 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.

Cold water may be used.

 

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.

Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or

waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth

resuscitation. Seek medical attention.

 

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.

Mixture with charcoal ignites on heating.

Contact with combustible or organic materials may cause fire.

 

Special Remarks on Explosion Hazards:

It will react explosively with hydrocarbons.

Interaction of nitrates when heated with amidosulfates(sulfamates) may become explosively violent owing to liberation of dinitrogen oxide and steam.

Mixtures of sodium nitrate with powdered aluminum or its oxide were reported to be explosive.

Mixtures of sodium nitrate and barium thiocyanate may explode.

Mixture with sodium nitrate and powdered antimony explode.

Mixture of sodium nitrate and sodium thiosulfate or sodium phosphinate explode.

 

Section 6: Accidental Release Measures

 

Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container.

 

Large Spill:

Oxidizing material.

Stop leak if without risk. Avoid contact with a combustible material (wood, paper, oil, clothing...). Keep substance damp using water spray. Do not touch spilled material. Prevent entry into sewers, basements or confined areas; dike if needed. Call for assistance on disposal.

 

Section 7: Handling and Storage

 

Precautions:

Keep away from heat. Keep away from sources of ignition. Keep away from combustible material. Do not ingest. Do not breathe dust. Wear suitable protective clothing. If ingested, seek medical advice immediately and show the container or the label. Keep away from incompatibles such as reducing agents, combustible materials, organic materials, acids.

 

Storage: Keep container tightly closed. Keep container in a cool, well-ventilated area. Separate from acids, alkalies, reducing agents and combustibles. See NFPA 43A, Code for the Storage of Liquid and Solid Oxidizers.            

 

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. Dust respirator. Be sure to use an approved/certified respirator or equivalent.  Gloves.

 

Personal Protection in Case of a Large Spill:

Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.

 

Exposure Limits: Not available.
