Shen Zhiyong Hukou High School
There are many kinds of chemicals in middle schools, which have complex properties, one thing is dangerous, the other is dangerous, toxic and non-toxic, and dangerous, and they are absolutely inseparable. Therefore, management and storage are extremely difficult. I have been engaged in the management and storage of this bank for 20 years, and there have been no dangerous accidents. My main approach is to focus on the sharing method of theme regularity and characteristics under the principle of combining convenience and accessibility. The main focus of management is people's responsibility, so as to fully understand the performance, storage points, storage rules and addresses of drugs, so as to observe them frequently and find and deal with possible accidents in time.
I. Management Methods and Precautions
1, white phosphorus and yellow phosphorus will spontaneously ignite when exposed to air, and the gas is highly toxic, so they are all sealed with water. Bromine is volatile and vapor is toxic, so it should be stored in a low temperature and ventilated place.
2. Metals K, Na, Ca, Li, Zn powder and CaC2 Na2O2 are flammable and explosive in contact with water, and K and Na are sealed with kerosene. Flammable products in contact with water are strictly prohibited from leaking and contacting water sources.
3, strong oxidant contact with flammable materials, will produce oxidation and spontaneous combustion caused by explosion, to be stored separately, it is strictly prohibited to mix, rely on, centralized storage, impact, close to the fire source.
4, drama drugs, strong rot products must be strictly managed, strictly control the distribution quantity and distribution target.
5. Most organic substances are flammable, toxic and corrosive, so good ventilation and exhaust should be paid attention to in management.
