TYPES OF HAZARD
|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE-FIGHTING|
|FIRE||Not combustible.||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. Combat fire from a sheltered position.|
|EXPOSURE||AVOID ALL CONTACT!||FIRST AID: USE PERSONAL PROTECTION. IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Cough. Sore throat. Chest tightness. Shortness of breath. Nausea. Vomiting. Symptoms may be delayed. See Notes.||Use closed system or ventilation.||Fresh air, rest. Half-upright position. Administration of oxygen may be needed. Refer immediately for medical attention.|
|Skin||Redness. ON CONTACT WITH LIQUID: FROSTBITE.||Cold-insulating gloves. Protective clothing.||ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention.|
|Eyes||Redness. Watering of the eyes. ON CONTACT WITH LIQUID: FROSTBITE.||Wear face shield or eye protection in combination with breathing protection.||Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.|
|PACKAGING & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Ventilation. Shut off cylinder if possible. Remove gas with fine water spray. Isolate the area until the gas has dispersed.||
Symbol: T+; R: 26-34; S: (1/2)-9-26-36/37/39-45; Note: U
UN Hazard Class: 2.3; UN Subsidiary Risks: 8
Contains gas under pressure; may explode if heated
Fatal if inhaled
Causes serious eye irritation
May cause respiratory irritation
Causes damage to lungs
Causes damage to the lungs through prolonged or repeated exposure
|EMERGENCY RESPONSE||SAFE STORAGE|
|NFPA Code: H4; F0; R1.||Fireproof if in building. Isolated from work area. Separated from incompatible materials. See Chemical Dangers. Cool. Dry. Ventilation along the floor.|
Physical State; Appearance
COLOURLESS COMPRESSED LIQUEFIED GAS WITH CHARACTERISTIC ODOUR.
Occupational exposure limits
Routes of exposure
The substance can be absorbed into the body by inhalation.
Effects of short-term exposure
Effects of long-term or repeated exposure
|PHYSICAL PROPERTIES||ENVIRONMENTAL DATA|
Boiling point: 8°C
Melting point: -128°C
Relative density (water = 1): 1.4
Solubility in water: reaction
Vapour pressure, kPa at 20°C: 161.6
Relative vapour density (air = 1): 3.4
A serious intoxication may develop even without experiencing symptoms of irritation or detecting the characteristic odour (grass or hay).
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 are therefore essential.
Do NOT spray water on a leaking cylinder (to prevent corrosion of the cylinder).
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
The information in this ICSC would also apply to phosgene generated by chemical reactions or by decomposition of organic compounds containing chlorine.
