Material Safety Data Sheet for Sodium Azide
Chemical Name Sodium Azide
Chemical Formula NaN3
CAS Number 26628-22-8
Very toxic if swallowed. Contact with acids liberates very toxic gas.
First Aid Measures
Eye Contact Irrigate thoroughly with water for at least 15 minutes. Seek medical advice.
Skin Contact Wash skin thoroughly with soap and water for at least 15 minutes. Remove contaminated clothing and wash before re-use. In severe cases, obtain medical attention.
Inhalation Remove from exposure, rest and keep warm. In severe cases, seek medical advice.
Ingestion Wash out mouth thoroughly with water and give plenty of water to drink. Seek medical advice.
Accidental Release Measures
Wear appropriate protective clothing. Inform others to keep a safe distance. Spread soda ash liberally over spillage. If local regulations permit, mop up cautiously with plenty of water and run to waste, diluting greatly with running water. Otherwise transfer to container and arrange removal by disposal company. Wash site of spillage thoroughly with water.
Handling and Storage
Handling Avoid prolonged contact with copper or lead, especially in drainage systems or mercury and other heavy metals which may result in the formation of explosive azides. Under no circumstances eat, drink or smoke while handling this material. Wash hands thoroughly after working with this material. Contaminated clothing should be removed and washed before re-use.
Exposure Controls / Personal Protection
Respirator Dust respirator
Ventilation Extraction hood
Gloves Rubber or plastic
Eye Protection Lab goggles or face shield
Other Precautions Plastic apron, sleeves, boots - if handling large quantities.
Physical and Chemical Properties
Melting Point No data available
Boiling Temperature No data available
Density No data available
Vapor Pressure No data available
Solubility in Water Very soluble

Stability and Reactivity
Stable unless heated.
Slow reaction at ambient temperature unless water contains dissolved carbon dioxide. Decomposes violently with chromyl chloride. Contact with acids liberates highly toxic gas: forms readily detonable salts with many materials, particularly heavy metals.
After ingestion, irritation of mucous membranes in the mouth, pharynx, esophagus and gastrointestinal tract. Danger of skin absorption.
Chemical residues are generally classified as special waste, and as such covered by regulations which vary according to location. Contact your local waste disposal authority for advice, or pass to chemical disposal company. Rinse out empty containers thoroughly before disposal.
