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 flammable substances.
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.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
ODOURLESS COMPRESSED GAS

PHYSICAL DANGERS:
The gas is heavier than air.

CHEMICAL DANGERS:
The substance is a strong oxidant and reacts with combustible and reducing materials, causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

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:
Lungs may be affected by inhalation of high concentrations.
