Health Hazards Information - Recommended Personal Protective Equipment: Maximum protective
clothing; goggles and face shield; Symptoms Following Bposure: Severe burns caused by burning metal
or by caustic soda formed by reaction with moisture on skin; General Treatment for Ecposure: SKIN:
brush off any metal, then flood with water for at least 15 min.; treat as heat or caustic burn; call a
doctor; Toxicity by Inhulation (ThresholdLimit Value): Not pertinent; Short-Tern ExposureLimits: Not
pertinent; Toxicity by Ingestion: Not pertinent; Late Toxicity: None; Vqor (Gas) Im*tant

Extinguishing Agents: Dry soda ash, graphite, salt, or other approved dry powder such as dry
limestone; Fire Extinguishing Agents Not To Be Used: Water, carbon dioxide, or halogenated
extinguishing agents; Special Hazards of Combustion Products: The fumes of burning sodium are
highly irritating to the eyes, skin, and mucous membranes.; Behavior in Fire: Not pertinent; Ignition

Chemical Reactivity - Reactivity with Water: Sodium reacts violently with water, forming flammable
hydrogen gas, and caustic soda solution. Fire often accompanies the reaction; Reactivity with Common
Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and
Caustics: After the reaction with water, the caustic soda formed as a by-product can be diluted with
water and then neutralized with acetic acid; Polymerization: Not pertinent; Inhibitor ofPo&m&ation:
Not pertinent.
