(1) Before entering the laboratory, you should preview the experiment, master the operation process and pipette tip principle, and clarify the properties of all drugs. It is estimated that dangerous experiments may occur, and precautions should be taken during operation.

(2) Before starting the experiment, check whether the instrument is intact and whether the device is correct and secure. Smoking or eating or drinking in the laboratory is strictly prohibited. After the experiment, wash your hands carefully.

(3) It is absolutely not allowed to mix various chemicals arbitrarily to avoid accidents. Don't touch the medicine with your hands, don't put your nostrils close to the mouth of the container to smell the medicine, and don't taste any medicine.

(4) The remaining drugs in the experiment can neither be put back into the original bottle, nor can they be discarded at will, nor can they be taken out of the laboratory, but should be put back into the designated container.

(5) Pay attention to safety when heating the lamp. When the alcohol lamp is about to burn out and the light has not been extinguished, do not inject fuel; when the alcohol lamp is out, cover it with a lamp cap, do not blow it with your mouth, to prevent accidents; do not use an alcohol lamp to light it, so as not to Alcohol spills, causing burns. Lighted matches should be extinguished immediately after use, and should not be thrown around.

(6) When pouring medicine or heating liquid, do not look down on the container to prevent splashing. When the test tube is heated, do not turn the mouth of the test tube towards yourself or others, and move the test tube back and forth to make the test tube heat evenly and prevent the liquid from spraying out; do not touch the hot test tube with the cold wick.

(7) When dissecting animals, ether is easy to volatilize and turn into gas. If people inhale too much ether vapor, it will cause headache and nausea. Animals should be quickly anesthetized during the experiment, and the windows should be opened to allow air to circulate.
