First, the temperature at which the pesticide is stored should not exceed 25 degrees Celsius, and it should be kept away from fire sources to prevent decomposition of the agent at high temperatures.
Second, pesticides should be concentrated in one place, marked, and bottled pesticides should be stored before inspection. If the bottle is broken, replace the package and label it to prevent misuse.
Third, the powder pesticide should be placed in a dry place to prevent moisture from agglomerating and failing.
Fourth, do not store pesticides together with seeds, food, cooking oil, etc.
Fifth, pesticides with strong volatility should be sealed to prevent evaporation. Such as dichlorvos, pyrethroid pesticides.
Sixth, pesticides should be classified and stored. According to chemical composition, pesticides can be divided into three categories: acidic, alkaline and neutral. Acidic pesticides include trichlorfon, fruit picking, and dichlorvos. Alkaline pesticides include methamidophos, zinc thiophosphorus and the like. These three types of pesticides should be stored separately, not too close to prevent the deterioration of pesticides.
Seventh, do not put pesticides and explosives together, such as smoked agents, gasoline, etc., to prevent fires.
Venous cannula is also a deep venous puncture catheter. The method is to select the appropriate puncture site and insert the needle under the skin, and insert the needle with negative pressure until the dark red blood is absorbed, indicating that the needle has entered the vein, and the guide wire is inserted. Withdraw the puncture needle to leave the guide wire in the blood vessel, and then insert the venous catheter that needs to be indwelled along the guide wire, then exit the guide wire, inject diluted heparin saline and fix the catheter, the deep venous catheterization is completed. The veins for puncture and catheterization are usually selected clinically, including the subclavian vein, internal jugular vein, and femoral vein. After the puncture catheter is indwelled, attention must be paid to the care of the puncture site to avoid infection with thrombus or catheter falling off.
