Prevention and treatment of common accidents in the laboratory

1.Eliminate man-made hidden dangers.

The main body involved in the experimental work is people, and the unsafe factors of people are the most important reasons for the occurrence of laboratory safety accidents. Therefore, only by starting from "people" and improving the safety awareness and literacy of experimenters through various means can potential safety hazards be minimized.

2.Build a secure environment.

A good safety environment is an important factor to ensure the safety of the laboratory, and the construction of a safe environment should be carried out from the hardware and software.

Hardware: The laboratory (building) should be equipped with complete safety facilities, such as fire-fighting equipment, alarm devices, emergency sprinkler devices, eyewashes, first-aid kits, waste collection devices, etc. It is necessary to frequently inspect the safe passage to ensure that the safe passage is unblocked, and to ensure that the electricity and water used for the experiment are safe and qualified.

Software: Clarify the person responsible for the safety of each laboratory, post obvious signs for the potential hazards of each laboratory, clearly inform the safety precautions and rules for the use of various instruments and equipment, and clearly mark the hazards and emergency treatment measures of the drugs. It is necessary to conduct regular safety inspections, carry out safety learning and safety knowledge experimental technology and management competitions, formulate strict reward and punishment measures, and create a safe atmosphere.

3.Improve the system and improve safety awareness.

The establishment of a sound and clear laboratory management system and strict implementation is an important guarantee for the sustainable development of laboratory safety work, and it is also a necessary condition for the operation of the safety access system. The answer comes from:

Normally, common accidents in the laboratory, such as students accidentally being burned during operation, can be washed with cold water at this time, and it may also cause some operations to cause the poetry to flow blood.

Common accidents in the laboratory are caused by chemical reactions, and prevention must be prepared and sprinkled to extinguish the fire.

A common accident in the laboratory is the leakage of chemicals. Prevention is to do a good job in the management of chemicals.

A common failure in the laboratory is that there may be a certain amount of high-temperature substances, or leakage or combustion, and other dangerous phenomena.

Be sure to pay attention to the safe use of some chemicals and the temperature at which they are stored.

First of all, depending on your lab situation, whether it is a physics lab or a chemistry lab. Different laboratories have different plans.

The reasons for the frequent occurrence of laboratory safety accidents are as follows:

1. The experimental operation is not standardized. Illegal operation or misoperation, such as the use of volatile chemical reagents, uneasy operation requirements, not timely covering; Improper or unqualified operation of high-pressure and high-energy experimental devices; When distilling or concentrating volatile toxic chemical reagents, they are not operated in a ventilated kitchen, etc.

2. Dangerous goods in the laboratory are not properly placed. For example, chemicals and wastes are not classified and stored according to regulations, and toxic waste liquid is dumped at will, and waste is littered.

3. Negligence in laboratory safety management. Among all the reasons, the most important is the negligence of the laboratory for safety management, and the neglect and paralysis of the mind have led to accidents in many cases. Here are some examples:

1. Laboratory equipment and facilities are aging or missing, such as ventilation facilities can not collect and discharge toxic gases, and there is no waste chemical collector.

2. Eating and drinking in the laboratory, and eating contaminated food by mistake.

3. Failure to wear protective equipment according to regulations.

In the face of bloody lessons, many laboratories have established corresponding laboratory safety management systems, such as the implementation of the laboratory safety responsibility system, regular safety training for students, regular inspections and spot checks on safety facilities, and so on.

In fact, the establishment of the system does not mean that the problem is solved, and there is still a lot we need to do for laboratory safety, among which the most important thing is to start from ourselves and adhere to the experimental norms.

1.Fire accidents.

Cause: Forgetting to turn off the power cause the equipment or electrical appliances to be energized for too long, the temperature is too high, and the fire is caused; careless operation or improper use, so that the ignition source comes into contact with flammable substances, causing fire; The power supply line is aging and overloaded, resulting in heating of the line and causing fire; Littering cigarette butts, contact with flammable substances, causing fire, etc.

This type of accident is universal and can happen in any laboratory.

2.**Accident.

Cause: Violation of operating procedures, ignition of flammable materials, and then lead to **; The equipment is aging, there are faults or defects, resulting in the leakage of flammable and explosive materials, and sparks.

Arouse**. Most of these accidents occur in laboratories with flammable and explosive materials and pressure vessels.

3.Biosecurity incidents.

Causes: Negligence and accidents in the management of microbiology laboratories can not only lead to the infection of laboratory staff, but also cause environmental pollution and large-scale population infection; The waste produced by biological laboratories is even more dangerous than that of chemical laboratories, and biological wastes contain infectious germs, viruses, chemical pollutants and radioactive hazardous substances, which can pose great harm to human health and environmental pollution.

4.Poisoning accidents.

Causes: Violation of operating procedures, bringing food into the laboratory of toxic substances, resulting in accidental ingestion poisoning; The equipment and facilities are aging, there are faults or defects, resulting in the leakage of toxic substances or the discharge of toxic gases, resulting in poisoning; Poor management, resulting in the scattering and loss of toxic substances, causing environmental pollution; The wastewater discharge pipeline is blocked or out of course, resulting in the flow of toxic wastewater without treatment, causing environmental pollution.

Most of these accidents occur in chemical laboratories with chemicals and highly toxic substances and in laboratories with toxic emissions.

5.Equipment damage accidents.

Cause: Sudden power failure caused by line failure or lightning strike, resulting in equipment damage caused by the failure of the heated medium to return to its original state as required; Equipment moving at high speed is damaged due to collision or crushing due to careless operation. Most of these accidents occur in laboratories heated with electricity.

6.Electromechanical injury accidents.

Causes: Improper operation or lack of protection, resulting in extrusion, throwing off and collision injuries; Violation of operating procedures or faults and defects due to aging equipment and facilities, resulting in leakage electric shock and arc sparks; Improper use causes harm to people with high-temperature gases and liquids.

This kind of accident mostly occurs in mechanical laboratories with high-speed rotation or impact movements, or electrical laboratories with live operations and some laboratories with high temperatures.

7.Theft of equipment or technology.

Reason: The large turnover of laboratory personnel, the difficulty of equipment and technical management, and the weak security awareness of laboratory personnel allow criminals to take advantage of it.

This kind of accident is a common occurrence of laboratory safety, which not only causes property damage, affects the normal operation of the laboratory, and may even cause the leakage of core technology.

Hope it helps, thank you.
