TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO contact with flammables.	In case of fire in the surroundings, use appropriate extinguishing media.
EXPLOSION			In case of fire: keep cylinder cool by spraying with water. NO direct contact with water.

EXPOSURE		AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Cough. Sore throat. Laboured breathing. Shortness of breath.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin	Redness. Pain. Skin burns.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
Eyes	Redness. Pain. Burns.	Wear eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid. Remove gas with fine water spray. Do NOT absorb in saw-dust or other combustible absorbents.	EC Classification UN Classification UN Hazard Class: 2.3; UN Subsidiary Risks: 8 GHS Classification

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-20G2TC. NFPA Code: H3; F0; R1.	Separated from incompatible materials. See Chemical Dangers. Cool. Keep in a well-ventilated room.

IMPORTANT DATA

Physical State; Appearance
YELLOW GAS WITH PUNGENT ODOUR.

Physical dangers
The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.

Chemical dangers
Decomposes on heating and on contact with water. This produces toxic and corrosive fumes including hydrogen chloride and nitrogen oxides. Reacts violently with strong oxidants. Attacks metals. The substance is a strong oxidant. It reacts with combustible and reducing materials.

Occupational exposure limits
TLV (NOT-ESTABLISHED):.

Routes of exposure

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 is corrosive to the eyes, skin and respiratory tract. Inhalation of this gas may cause lung oedema. See Notes.

Effects of long-term or repeated exposure

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: -5 to -6°C Melting point: -64°C Density: g/cm³ Solubility in water: reaction Vapour pressure, kPa at 20°C: 340 Relative vapour density (air = 1): 2.3 Relative density of the vapour/air-mixture at 20°C (air = 1): 5.2	The substance is harmful to aquatic organisms.

NOTES

Reacts violently with fire extinguishing agents such as water.
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.
Rinse contaminated clothes (fire hazard) with plenty of water.
Check oxygen content before entering area.
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
