Chemical 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 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:

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

No reflux, no water cooling, and a constant temperature 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.

When using electrical appliances, check the wires first to prevent short circuits and leakage.

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

Heat with open flame and ventilate 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.

The laboratory must be kept 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 inspected 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 seriously, be bold and careful, and always stay safe

Having

weighted it we know is importance.

Having considered it we know is

drawback.

2. There is no other way to identify errors other than experimentation.

Nothing but experiment can

distinguish mistakes.

3. Science is the commander, practice is the warrior.

Science is a commander while

practice is a soldier.

4. A good scholar will do his best, and a good practitioner will face difficulties.

Find out how to learn to

learn well, Find out how to go to go

farther.

5. Rumors are not as good as Seeing with your own eyes is worse than seeing the shadow.

Seeing is better than hearing and in

vesting is worse than seeing.

6. Those who know are not as good as those who do.

To do is better than to

say.

observation and experiments.

3. Hearing is not as good as seeing, and seeing is not as good as practicing.
