|SODIUM AZIDE||ICSC: 0950 (April 2014)|
|Hydrazoic acid, sodium salt
| CAS #: 26628-22-8
| UN #: 1687
|EC Number: 247-852-1
|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with acids or metals. Heating will cause rise in pressure with risk of bursting.||NO contact with acids or heavy metals. Do NOT expose to heat, friction or shock.||Use dry sand, special powder. In case of fire: keep drums, etc., cool by spraying with water.|
|PREVENT DISPERSION OF DUST! STRICT HYGIENE!|
|Inhalation||Cough. Headache. Nasal congestion. Fall in blood pressure. Shortness of breath. See Notes.||Use local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Refer immediately for medical attention.|
|Skin||Protective gloves.||Rinse skin with plenty of water or shower. Seek medical attention if you feel unwell.|
|Eyes||Redness. Pain.||Wear safety spectacles or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Abdominal pain. Nausea. Sweating. Fall in blood pressure. Increased heart rate. Weakness. Blurred vision. Shock or collapse. See Effects of short-term exposure||Do not eat, drink, or smoke during work.||Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer immediately for medical attention.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered plastic containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.||
According to UN GHS Criteria
Fatal if swallowed
Causes eye irritation
May cause respiratory irritation
May cause damage to cardiovascular system
Very toxic to aquatic life
|Separated from food and feedstuffs, acids and metals. See Chemical Dangers. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.|
|Do not transport with food and feedstuffs.|

|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 0.29 mg/m3 (ceiling value); A4 (not classifiable as a human carcinogen).
MAK: 0.2 mg/m3; peak limitation category: I(2); pregnancy risk group: D.
EU-OEL: 0.1 mg/m3 as TWA; 0.3 mg/m3 as STEL; (skin)
|The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.|
|In presence of heat, acids and water sodium azide is readily transformed to hydrazoic acid, the vapour of which may be present whenever the salt is handled.
Inhalation of high concentrations of hydrazoic acid may cause severe respiratory irritation including lung oedema.
Decomposition of sodium azide produces large amount of gases. This generates explosion hazard in confined spaces.
