... /Sodium/ is to some extent pyrophoric. Dispersions of sodium in volatile solvents may become pyrophoric if the solvent evaporates round the neck of a container.

The ignition temp of sodium in air depends on size of surface exposed: vapor ignites at room temp; droplets at about 250 °F; an agitated pool at 400 °F; a calm pool at 500 to 800 °F. In the absence of moisture and hydrogen, the reaction is insignificant below 1000 °F.

... Improved methods for extinction of liq sodium ... fires are described which involve application of low-melting inorganic powder mixtures which melt and form a protective crust. Mixtures of sodium carbonate or graphite, with lithium carbonate, sodium chloride or sodium fluoride are very effective for sodium.

use approved Class D extinguishers or smother with dry sand, dry clay, or dry ground limestone. DO NOT use carbon dioxide or halogenated extinguishing agents. DO NOT use water. Violent reaction may result.

If material on fire or involved in fire: Do not use water. Do not use carbon dioxide. Use graphite, soda ash, powdered sodium chloride, or suitable dry powder.

Sodium and carbon dioxide are normally unreactive till red-heat has been attained, but mixtures of the 2 solids are impact-sensitive and explode violently. Carbon dioxide is unsuitable as an extinguishant for the burning metal alone, as the intensity of combustion is incr by replacing air with carbon dioxide (72.7% oxygen content). However it has been used successfully to extinguish solvent fires where sodium was also present, since it often fails to ignite because of the blanketing effect of solvent vapor. Conversely addition of kerosene to burning sodium enables the whole to be extinguished with carbon dioxide. Finely divided silica (sand) will often react with burning sodium, so is not entirely suitable as an extinguishant. (Anhydrous sodium carbonate and sodium chloride are suitably unreactive for this purpose) ...

Store in cool, dry, well-ventilated location. Separate from water.

Serum cap closures are safer than screw caps.

Sodium must be stored to avoid contact with water, halogenated hydrocarbons, phosphorus and phosphorus compounds and sulfur and sulfur compounds since violent reactions occur. Protect storage containers from physical damage. Keep in an inert atmosphere or under oil. Requires special precautions to avoid contact with moisture, including condensation from other objects and perspiration. Store in a dry, fire resistive room exclusively for sodium storage. Sprinkler systems should not be used, so keep combustibles away. Remove only the amount of sodium needed for immediate use and place dry in a friction top metal can under a layer of oil. Transport in a special container with a tight fitting cover.

One-pound bricks and smaller amounts may be encountered in chemistry laboratories, where it is usually protected from the air by immersion in an aliphatic oil.

Keep water away from release. Do not create dust. Shovel into suitable dry container.

Absorb spilled sodium dry, cover remainder with kerosine, paraffin oil or dry sand, eliminate last traces with methylated spirit.

Evacuate persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Put on proper protective equipment. Blanket with appropriate inert material. Scoop up and place in a suitable, sealed container. Ventilare area after clean-up is complete. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstreen users of potentially contaminated waters...

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Incineration with absorption of oxide fumes.

SCRAPS ... SHOULD BE DESTROYED BY REACTION WITH N-BUTYL ALCOHOL.

In a discussion of safe methods for lab use of sodium, disposal of small quantities (up to 5 to 10 g) by immersion on isopropanol, which may contain up to 2% of water to incr the rate of reaction, is recommended. Quantities up to 50 g should be burned in a heavy metal dish, using a gas flame, (with suitable arrangements for dispersion or absorption of the alkaline particulate smoke so produced).

/SIGNS AND SYMPTOMS/ Short-Term Exposure: Inhalation: Contact with water, including perspiration, causes the formation of sodium hydroxide fumes which are highly irritating to skin, eyes, nose and throat. May cause sneezing and coughing. Very severe exposures may result in difficult breathing, coughing, and chemical bronchitis. High exposures can cause pulmonary edema, a medical emergency that can be delayed for several hours. This can cause death. Skin: Contact may cause itching, tingling, thermal and caustic burns and may cause permanent damage. Eyes: May cause tearing, very painful irritation, and burns. Contact with eyes may result in permanent damage and loss of sight. Ingestion: Causes immediate intense burning sensation in mouth, throat and stomach, followed by salivation, vomiting, rapid breathing, symptoms of shock, diarrhea, loss of consciousness and death.

/SIGNS AND SYMPTOMS/ Occasional severe burns of eyes which have been caused by sodium are attributable principally to sodium hydroxide.

/SIGNS AND SYMPTOMS/ Extremely caustic to all tissue.

/SIGNS AND SYMPTOMS/ Corrosive. Causes severe eye and skin burns.

Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... .
