What are the methods for dealing with common accidents in the laboratory?

In the event of a fire, first cut off the power supply, and then choose the appropriate method of extinguishing the fire based on its nature. If the glass container breaks, the appropriate handling method should be chosen based on the toxicity of the substances contained within it; in the case of toxic gases, ventilation is necessary, along with the use of absorbents. In the event of a mercury leak, it must be collected promptly and sulfur should be scattered. Try not to conduct experiments alone; working in two is more convenient and safer.

If it is a fire involving oil, never use water to extinguish it; instead, use a wet cloth and sand.

In the case of acid burns, rinse immediately with plenty of water, and then wash with soapy water； In case of alkali burn, rinse first with clean water, then with a 2% boric acid solution. Finally, rinse with clean water; in severe cases, take the victim to the hospital for treatment. In case of an electric shock, cut off the power supply first before taking the injured person to the hospital for emergency care. In case of a fire, do not shout or run around; instead, extinguish the fire promptly. In the event of a large-scale fire, one should first quickly leave the affected area through the safety exits, and once safe, call 119. It is not advisable to rush into the fire scene alone to put out the fire (the willingness to protect the company’s property is commendable, but such actions will only lead to unnecessary losses). In the event of a localized fire, the power supply should be cut off immediately, and an appropriate fire extinguisher should be used to put out the fire
