Environmental hazards: harmful to the environment, which can pollute water, soil and atmosphere.
Danger of explosion: This product is flammable. Hazard characteristics: flammable, and can form explosive mixture when mixed with air. Danger of burning and explosion in case of heat source and open flame. It reacts violently with nitrogen dioxide, nitrogen tetroxide and nitrogen oxides. And react violently with other oxidants. Gas is heavier than air, it can spread to a considerable distance at a lower place, and it will catch fire when it meets a fire source.
Harmful combustion products: carbon monoxide and carbon dioxide.
Fire extinguishing method: cut off the gas source. If the gas source cannot be cut off, it is not allowed to extinguish the flame at the leak. Spray water to cool the container, and if possible, move the container from the fire to an open place. Extinguishing agent: atomized water, foam, carbon dioxide and dry powder. China MAC (mg/m&; Sup3): There is no standard.
Mac (mg/m&; sup3): 100
ACGIH asphyxiating gas
TLVWN: No standard has been established.
Engineering control: the production process is closed and fully ventilated.
Respiratory system protection: generally no special protection is needed, but it is recommended to wear a self-priming filter gas mask (half mask) under special circumstances.
Eye protection: Generally, special protection is not needed, and chemical safety glasses can be worn when exposed to high concentrations.
Physical protection: wear anti-static work clothes.
Hand protection: wear gloves for general operation.
Other protection: Smoking is strictly prohibited in the workplace. Avoid long-term repeated contact. Work in storage tanks, confined spaces or other high concentration areas must be supervised. Propylene mainly invades the human body through the respiratory tract. Inhalation of 6.4% concentration for 2.25 minutes resulted in abnormal sensation and inattention; 12.8%, 1min, the same symptoms are more obvious; 15%, 30min or 24% ~ 33%, 3min can cause unconsciousness; More than 40% people will lose consciousness after only 6 seconds, causing vomiting and dizziness. After a few minutes of contact, it can still cause eyelids and facial flushing, tears and cough; 50%2min caused anesthesia, but it can be completely recovered after stopping contact.
The olfactory threshold of propylene is 17.3mg/m3, and the eyes are slightly sensitive when it is near 1mg/m3. The chronic effect of propylene is similar to that of ethylene. Dangerous goods code: 2 10 18
