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.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

In case of fire: keep cylinder cool by spraying with water.
EXPOSURE
STRICT HYGIENE!

 •INHALATION Cough. Sore throat. Laboured breathing. Shortness of breath.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. 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 STORAGE PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Ventilation. NEVER direct water jet on liquid. Personal protection: complete protective clothing including self-contained breathing apparatus.
Fireproof if in building.

UN Hazard Class: 2.3
UN Subsidiary Risks: 5.1

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

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance is a strong oxidant and reacts violently with combustible and reducing materials, with risks of fire and explosion hazard. Reacts violently with nitrogenous bases and finely divided organic materials, causing fire and explosion hazard. Attacks some forms of plastic, rubber and coatings.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 3 ppm as TWA, 6 ppm as STEL; (ACGIH 2004).
OSHA PEL: TWA 3 ppm (13.5 mg/m3)
NIOSH REL: TWA 3 ppm (14 mg/m3) ST 6 ppm (28 mg/m3)
NIOSH IDLH: 100 ppm See: 7616946


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. Inhalation of this gas may cause lung oedema (see Notes). Inhalation of high concentrations may cause formation of methaemoglobin. The liquid may cause frostbite. Medical observation is indicated. The effects may be delayed.

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

ENVIRONMENTAL
DATA

N O T E S
Depending on the degree of exposure, periodic medical examination is suggested. 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. 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. Card has been partly updated in October 2005. See section Emergency Response.
