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. NO contact with combustible and reducing materials, strong bases, amines and finely divided metals.	In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION	Risk of fire and explosion on contact with combustible and reducing materials.		In case of fire: keep cylinder cool by spraying with water.

EXPOSURE		STRICT HYGIENE!
INHALATION	Cough. Laboured breathing. Sore throat.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
SKIN	ON CONTACT WITH LIQUID: FROSTBITE.	Cold-insulating gloves. Protective clothing.	ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
EYES		Safety goggles 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

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

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes (fluorine, fluorine oxides, chlorine, chlorine oxides). The substance is a strong oxidant and reacts violently with combustible and reducing materials, causing fire and explosion hazard. Attacks some forms of plastics, rubber and coatings.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 3 ppm; 13 mg/m³ as TWA; 6 ppm; 25 mg/m³ as STEL (ACGIH 1991-1992).

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 SHORT-TERM EXPOSURE:
The substance irritates the respiratory tract. The liquid may cause frostbite.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood , resulting in forming of methaemoglobin. The substance may cause fluorosis (see Notes).

ENVIRONMENTAL
DATA

NOTES

Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
