Types of hazard / Exposure

Acute hazards / Symptoms

Prevention

First aid / Fire fighting

Fire

Extremely flammable. Gives off irritating or toxic fumes (or gases) in a Fire.

NO open flames, NO sparks, and NO smoking.

Shut off supply; if not possible and no risk to surroundings, let the Fire burn itself out; in other cases extinguish with dry powder, carbon dioxide.

Explosion

Gas/air mixtures are explosive.

Closed system, ventilation, Explosion-proof electrical equipment and lighting.

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

Exposure

Strict hygiene！

Inhalation

Cough. Laboured breathing. Sore throat.

Ventilation, local exhaust, or breathing protection.

Fresh air, rest. Half-upright position. Artificial zespiration may be eeded. Refer for medical ttention.

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 ttention.

Eyes

Redness. Pain. Blurred vision.

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

Evacuate danger area! Consult an expert! Ventilation. Remove all ignition sources. NEVER direct water jet on liquid. (Extra personal protection: complete protective clothing including self-contained breathing apparatus.)

Important data

Physical State; Appearance
Colourless compressed liquefied gas, With pungent odour.
Physical dangers
The gas is heavier than air and may travel along the ground; distant ignition possible.
Chemical dangers
The substance decomposes on burning producing toxic gases including nitrogen oxides. The solution in water is a strong base, it reacts violently with acid and is corrosive. Reacts violently with strong oxidants and organic compounds causing Fire and Explosion hazard. Attacks many non-ferrous metals and plastic.
Occupational Exposure limits
TLV: 5 ppm as TWA; 15 ppm as STEL; (skin); (ACGIH 2002).MAK: 5 ppm; 9.4 mg/m³ ; Peak limitation category: I(2);MAK: class Pregnancy risk group: IIc (2002).EU OEL: 5 ppm; 9.4 mg/m³ ; (EU 2002).

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 severely irritating to the eyes and the respiratory tract. Rapid evaporation of the liquid may cause frostbite.
