TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Heating will cause rise in pressure with risk of bursting.  NO open flames, NO sparks and NO smoking. NO contact with flammables.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. 
 
EXPOSURE      
Inhalation Cough. Dizziness. Sore throat. Visual disturbances. See Notes.    Refer for medical attention. 
Skin      
Eyes   Wear safety goggles.   
Ingestion      

SPILLAGE DISPOSAL
PACKAGING & LABELLING

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-20S1072 or 20G1O.  Fireproof. Separated from combustible substances and reducing agents. Cool. 

IMPORTANT DATA
Physical State; Appearance
ODOURLESS COMPRESSED GAS. 

Physical dangers
The gas is heavier than air. 

Chemical dangers
The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation. 

Inhalation risk
 

Effects of short-term exposure
The substance at very high concentrations is irritating to the respiratory tract. The substance may cause effects on the central nervous system, lungs and eyes. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of high concentrations may cause effects on the lungs.
