TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire. Not combustible.

NO water. In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

In case of fire: cool cylinder by spraying with water but avoid contact of the substance with water.
EXPOSURE
AVOID ALL CONTACT!

 •INHALATION Burning sensation. Cough. Sore throat. Headache. Nausea. Vomiting. Shortness of breath. Laboured breathing. Symptoms may be delayed (see Notes).
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
 •SKIN Pain. Redness. Skin burns. ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves. Protective clothing.
ON FROSTBITE: do NOT remove clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
 •EYES Redness. Pain. Blurred vision. Severe deep burns. ON CONTACT WITH LIQUID: FROSTBITE.
Safety goggles, face shield, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION
Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Ventilation. Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus.
Keep in a well-ventilated room. Fireproof if in building. Cool. Dry.

UN Hazard Class: 2.3
UN Subsidiary Risks: 8

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

PHYSICAL DANGERS:
The gas is heavier than air.

CHEMICAL DANGERS:
Reacts violently with water and acids to produce toxic and corrosive fumes . Attacks glass and metal.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 ppm (Ceiling value); (ACGIH 2003).
OSHA PEL: none
NIOSH REL: C 0.1 ppm (0.4 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX


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

INHALATION RISK:
On loss of containment, a harmful concentration of this gas in the air will be reached very quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes , the skin and the respiratory tract. The liquid may cause frostbite. Inhalation of this gas may cause lung oedema (see Notes).

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the bones and teeth , resulting in fluorosis.
PHYSICAL
PROPERTIES
Boiling point: -40C
Melting point: -124C
Solubility in water: reaction
Relative vapour density (air = 1): 3.78
ENVIRONMENTAL
DATA

N O T E S
The occupational exposure limit value should not be exceeded during any part of the working exposure. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential.
