Hazard statements

OXIDIZER. CONTACT WITH OTHER MATERIAL MAY CAUSE FIRE. INHALATION CAUSES HEADACHES, DIZZINESS, DROWSINESS AND NAUSEA AND MAY LEAD TO UNCONSCIOUSNESS. MAY CAUSE RESPIRATORY TRACT IRRITATION. GAS REDUCES OXYGEN AVAILABLE FOR BREATHING. AT VERY HIGH CONCENTRATIONS, CAN DISPLACE THE NORMAL AIR AND CAUSE SUFFOCATION FROM LACK OF OXYGEN. MAY CAUSE TARGET ORGAN DAMAGE, BASED ON ANIMAL DATA. BIRTH DEFECT HAZARD - CAN CAUSE BIRTH DEFECTS. DEVELOPMENTAL HAZARD - CAN CAUSE ADVERSE DEVELOPMENTAL EFFECTS.

Precautionary statements

At very high concentrations, can displace the normal air and cause suffocation from lack of oxygen. Keep away from combustible material. Do not enter storage areas and confined spaces unless adequately ventilated. Avoid exposure - obtain special instructions before use. Do not breathe gas. Avoid exposure during pregnancy. Use only with adequate ventilation. Keep container tightly closed and sealed until ready for use. Wash thoroughly after handling.

Principle Routes of Exposure

Dermal contact. Eye contact. Inhalation.

Potential Acute Health Effects

Inhalation : Can cause central nervous system (CNS) depression. Slightly irritating to the respiratory system. At very high concentrations, can displace the normal air and cause suffocation from lack of oxygen. Exposure to decomposition products may cause a

Health hazards

Serious effects may be delayed following exposure Ingestion Ingestion of liquid can cause burns similar to frostbite. Skin May cause skin irritation. Dermal contact with rapidly evaporating liquid could result in freezing of the tissues or frostbite. Eyes May cause eye irritation. Liquid can cause burns similar to frostbite.
