Practice is the only criterion for testing truth

Discovery comes from exploration, and life lies in struggle!

Anyone who understands instruments, draws circuits, and does it himself; records data, draws lines, and analyzes errors must admit that experiment is the father of science.

All reasoning must be derived from observation and experiment.

Chemistry Laboratory Safety Song

Fire and water are merciless, human life is at stake, safety first, keep it in your heart.

The first is to prevent water hazards, the second is to prevent fire hazards, the third is to prevent explosions, and the fourth is to prevent electric shock.

Before the experiment, prepare in advance, and all protective equipment is available.

During the experiment, you are not allowed to leave without permission, and you must observe in time to prevent mutations.

Leave for a short time and be looked after by your companions. Pay special attention to the water and power outages.

Heating overnight is the most dangerous. If this is really necessary, five insurances are required:

Adjust the voltage, use relays, and silicone oil heat packs as heat sources.

No reflux is allowed, no water cooling is allowed, and the temperature must be constant before you can sleep peacefully.

Be careful when using water, keep the water pipes tightly connected, do not overflow the water, and remove the pipe after get off work.

Before using electrical appliances, check the power cord first to prevent short circuit and leakage.

Use gas with caution, be careful of ignition, stay away from solvents, and stay away from experiments.

Heating by open flame, ventilation first. High-pressure gas cylinders, keep them safe and far away.

Hydrogen cylinders must be handled strictly. Household refrigerator, not suitable for experiments.

Containers in the box must be tightly closed, placed stably, and labeled.

Highly toxic reagents should be collected by designated personnel, and metal potassium and sodium should be stored at designated points.

Do not store too much of various solvents, and store them in a shaded place, especially in summer.

Residues and waste liquids cannot be put into the pool. They should be sorted into categories and returned to their respective places.

In the laboratory, keep it clean and tidy. No eating or smoking is allowed.

Leaving the room in the end is the key. The water, electricity, windows and gate pins are restored.

Fire extinguishing equipment should be checked frequently and first aid medicines should be kept at hand.

In case of danger, turn off the power first. The alarm number can be found everywhere.

After this song, practice it conscientiously, be bold and careful, and stay safe forever
