Cut off the fire source. Wear self-contained breathing apparatus and general fire protective clothing. Block the leak under safety. Water spray mist reduces evaporation. Mix and absorb with sand or other non-combustible adsorbent. They is then transported to empty areas for burial, evaporation, or incineration. Such as a large amount of leakage, the use of embankment shelter, and then collection, transfer, recycling or harmless disposal after waste.
preventive measure
At a high concentration in the air, a gas mask should be worn. It is recommended to wear a self-contained breathing apparatus during emergency rescue or evacuation.
Eye protection: wear a chemical safety protection eye
mainly used as organic synthetic monomer, used for synthetic resin, plastics, coatings, printing ink, adhesives, lubricating oil additives, dental materials, fiber processing agent, paper agent, etc.
Storage method: store in a cool, ventilated warehouse. The library temperature should not exceed 37℃. Stay away from the fire and heat sources. Packaging shall be sealed and shall not be in contact with the air. Should be stored separately from oxidant, acid, alkali, avoid mixed storage. Should not be stored in large quantities or stored for a long time. Explosion-proof-type lighting and ventilation facilities are adopted. No use of mechanical equipment and tools prone to spark. The storage area shall be equipped with leakage emergency treatment equipment and suitable shelter materials.
