Risk characteristics:
Flammable, mixed with air to form an explosive mixture. Exposure to heat, sparks, flame, or oxidizing agents to burn and explode. The gas is heavier than air, can arrive at a far place lower spread, will encounter fire fire backdraft.
Solubility: soluble in water, soluble in ethanol, ether, etc..
Forbidden compounds: acids, halogen, anhydride, strong oxidizing agent, chloroform.
Emergency:
Skin contact: immediately remove contaminated clothing, wash with plenty of water, at least 15 min. Medical treatment.
Eye contact: immediately lift the eyelids, with a large number of flowing water or physiological saline rinse at least 15 min. Medical treatment.
Inhalation: quickly from the scene to the fresh air. Maintain airway patency. If breathing is difficult, give oxygen. If breathing stops, immediately carry on artificial respiration. Medical treatment.
Ingestion: oral intake of water gargle, to drink milk or egg white, doctor.
Respiratory protection: when the air concentrations exceed the standard, it is recommended to wear a self - absorption filter gas mask (full cover). Emergency rescue or evacuation, it is recommended to wear oxygen respirator or air breathing apparatus.
Eye protection: protection of respiratory system.
Body protection: wear anti-static work clothes.
Hand protection: wear rubber gloves.
Other: no smoking, eating and drinking water. Work finish, shower and change.
Leak emergency treatment:
Harmful combustion products: carbon monoxide, carbon dioxide, nitrogen oxide.
Fire extinguishing method:
Cut off gas source. If you can't cut off the gas supply, are not allowed to extinguish the flame leakeddepartment. Water cooling containers, if possible containers from fire to open. Extinguishing agent: fog water, anti - soluble foam, dry powder, carbon dioxide.
