Safe storage:
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Store in a cool, dry, well-ventilated warehouse, away from fire and heat sources, and store temperature not exceeding {{ 4}} ℃, relative humidity does not exceed 70%, keep the container sealed. It should be stored separately from oxidants, alkalis and edible chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials. The "five pairs" management system for toxic substances should be strictly implemented.
first-aid:
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; After contact, first quickly move the poisoned patient to fresh air, remove contaminated clothing, Wash the skin thoroughly, observe at least 24 ~ 48 hours for the responders, give oxygen in time, and give symptomatic treatment such as sedation, expectoration and antispasmodic drugs. When the eye is contaminated, use normal saline early Or rinse thoroughly with clean water, always be alert to the occurrence of delayed poisoning.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Take timely treatment to ensure the safety of staff ’s lives and property, you should learn the corresponding knowledge and emergency response plan beforehand To actively ensure safe production.
Leakage treatment:
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Quickly evacuate personnel from the leaked area to a safe area, and immediately isolate {{ 5}} m, strictly restrict access. Cut off the ignition source. It is recommended that emergency personnel wear self-contained positive-pressure respirators and anti-virus clothing. Do not directly touch the leak, cut off the leak source as much as possible. Prevent inflow into restrictive spaces such as sewers and flood ditches. For small leaks, absorb with sand, embankment or other inert materials. When there is a large amount of leakage, construct a dike or dig a pit to contain it. Cover with foam to reduce steam hazards. Use pump to transfer to tank truck or special collector, recycle or transport to waste disposal site for disposal.
Fire fighting methods:
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Firefighters must wear gas masks to extinguish the wind. Fire extinguishing agents come in the form of water mist, carbon dioxide, foam and sand.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; From this we can understand its destructive power The damage is very serious, so please learn professional emergency knowledge before operating.
