TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with flammable substances.
In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
 
EXPOSURE


INHALATION
Ventilation.
Fresh air, rest.
SKIN

First rinse with plenty of water, then remove contaminated clothes and rinse again.
EYES
Safety goggles.

INGESTION


SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Ventilation. NEVER direct water jet on liquid (extra personal protection: self-contained breathing apparatus).
Fireproof if in building. Separated from combustible and reducing substances. Cool.

UN Hazard Class: 2.3
UN Subsidiary Risks: 5.1

PHYSICAL STATE; APPEARANCE:
COLOURLESS GAS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes including fluoride. The substance is a strong oxidant and reacts with combustible and reducing materials. Reacts violently with ammonia, carbon monoxide, diborane, hydrogen, hydrogen sulfide, methane or tetrafluorohydrazine, causing explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 10 ppm; 29 mg/m3 (as TWA) (ACGIH 1995-1996).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.




EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver and kidneys.
PHYSICAL
PROPERTIES
 Boiling point: -129°C
Melting point: -208.5°C
Relative density (water = 1): see Notes		 Solubility in water: none
Vapour pressure, kPa at °C: see Notes
ENVIRONMENTAL
DATA
N O T E S
Vapor pressure is >1 atm at 20°C. Density of the liquid at boiling point: 1.885 kg/l. The odour warning when the exposure limit value is exceeded is insufficient. Methemoglobinemia has been observed in animals, but relevance to humans is unclear. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
