Extinguishing Media: Do not use water. Use class D metal fire agent, dry salt or sand.
Special Firefighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.
Unusual Fire & Explosion Hazards: Flammable solid. May self-ignite. Dust may form explosive mixtures with air. Dangerous when wet. Evolves flammable hydrogen with water. Oxidizes readily in air.
V. HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the physical, chemical and toxicological properties of sodium have not been thoroughly investigated and recorded.
Sodium rapidly forms caustic and highly corrosive sodium hydroxide with evolution of heat. Severe thermal and chemical burns will result at every point of human contact.
Acute Effects:
Inhalation: SEVERE IRRITANT AND CORROSIVE. Inhalation of dust will severely irritate the nasal cavity and respiratory tract.
Ingestion: SEVERE IRRITANT AND CORROSIVE. Ingestion will cause burns and perforations of the gastrointestinal tract.
Skin: SEVERE IRRITANT AND CORROSIVE. Severe thermal burns, corrosion and ulceration of the skin may occur on direct contact.
Eye: SEVERE IRRITANT AND CORROSIVE. Severe thermal burns, corrosion and ulceration of the eyes may occur on direct contact.
Chronic Effects: No chronic health effects recorded.
Target Organs: May affect the eyes, skin, mucous membranes, gastrointestinal and respiratory systems.
Carcinogenicity: NTP: No IARC: No OSHA: No
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention
INGESTION: Do not induce vomiting. If conscious, give the victim water and seek immediate medical attention.
SKIN: Remove contaminated clothing, brush material off skin, wash the affected area with soap and water for at least 5 minutes. Seek medical attention.
EYE: Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eyelids open. Get immediate medical attention.
VI. REACTIVITY DATA
Stability: Air sensitive, moisture sensitive.
Conditions to Avoid: Contact with water or of any fine dust with air.
Incompatibility (Material to Avoid): Water, alcohols, oxidizers, oxygen, carbon dioxide, halogens, halocarbons, acids, sulfur, sulfur dioxide, phosphorus, ammonia, chlorinated hydrocarbons, hydrogen peroxide, lead oxide, potassium oxides.
Hazardous Decomposition Products: Oxides of sodium, hydrogen.
Hazardous Polymerization: Will not occur.
VII. SPILL OR LEAK PROCEDURES
Steps to be Taken in Case Material is Released or Spilled: Wear appropriate respiratory and protective equipment specified in section VIII. Provide ventilation. Remove all sources of ignition. Cover with dry sand or other non-combustible material. Sweep or scoop up spill and place in a closed container for proper disposal.
Waste Disposal Method: Disposal must be made in accordance with Federal, State and Local regulations.
VIII. SPECIAL PROTECTION INFORMATION
Respiratory Protection: NIOSH approved respirator.
Ventilation: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels low. General exhaust is not recommended. Handle under argon.
Protective Gloves: Neoprene gloves
Eye Protection: Safety goggles
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.
IX. SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in a tightly sealed container in argon and under mineral oil, in a cool dry place. Handle in argon.
Other Precautions: Sodium is air and moisture sensitive. Handle and store in a controlled environment and under mineral oil. With moisture or human contact, metal rapidly forms caustic and highly corrosive alkali hydroxide with evolution of heat. Severe thermal and chemical burns will result.
Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and smoking. Do not blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
