How to do a good job in laboratory safety and prevent safety risks?

Nowadays, universities, research institutes, and enterprises attach great importance to laboratory hazardous chemicals.

management. How to put the safety management system.

Putting it into practice, not just talking about it? In today's developed information technology, the answer seems to be relatively clear - combined with information technology to strengthen the safety management of chemical reagents, the introduction of a set of functional, easy-to-use chemical reagent inventory management system will be a wise choice. In addition to the dynamic management functions of the whole life cycle of chemical reagents from procurement, warehousing, delivery, return, scrapping, etc., it is also in the management of hazardous chemicals.

There are also the following characteristics: (1) Hazardous chemicals combing: which are hazardous chemicals?

The system sorts out the hazardous chemicals in the laboratory through the CAS number of the chemicals, and gives suggestions for the allocation of hazardous chemicals according to the storage contraindication table, so as to guide the loading of hazardous chemicals on the shelves. (2) Realize the management of sub-warehouses and sub-authorities: the system sets up hazardous chemicals warehouses and ordinary reagent warehouses, and can set up the approval process for hazardous chemicals warehouses, and cooperate with explosion-proof cabinets, double locks and other measures for key control; For ordinary reagents, unattended warehouses can be used, and they do not need to be approved for use, through the mobile app

Experimenters can also easily view the MSDS data of reagents, understand the characteristics of hazardous chemicals in real time, and take corresponding protective measures. (4) The inventory of hazardous chemicals is clear and can be checked and dynamically updated in real time, which effectively reduces the waste of resources caused by repeated purchases and the potential safety hazards caused by excessive backlog of reagents. (5) Reagent barcode management, full traceability:

The barcode refined management method realizes the dynamic real-time traceability of reagents from procurement, warehousing, application, delivery, return, scrapping, etc. (6) The system can export the inventory ledger of hazardous chemicals.

and life cycle information, so as to achieve effective supervision of the whole life cycle of hazardous chemicals. (7) Multi-dimensional reagent information statistics can be carried out; Automatically obtain the monthly report of use, which is convenient to understand the information such as reagent requisition, the busyness of experimenters, fund statistics, project benefit ratio, etc., and provide data support for comprehensive decision-making.

Be prepared and protected to deal with an attack or avoid victimization, so that the protected object is in a safe state that is not in danger, is not violated, and does not have an accident. Obviously, safety is the goal, prevention is the means, and the basic connotation of security is to achieve or achieve the goal of security through the means of prevention.

When doing dangerous experiments, you must be accompanied by a teacher, and you must be accompanied by another person every time you do an experiment, and you cannot leave during the experiment. Laboratories should take protective measures.

The importance of laboratory safety is as follows:

The laboratory is an important place for experimental teaching, scientific research and social service. Laboratory safety management has a profound impact on staff.

From the layout of the laboratory, the maintenance of equipment, to the storage of hazardous chemicals, the use of instruments and equipment, the record of the bureau, the safety inspection records, to the management mode and management system of the laboratory, we are required to be rigorous and realistic, keep improving, and cultivate good habits of safety experiments.

However, there are many risk factors lurking in the laboratory, and a slight negligence is very prone to safety accidents, which affect our physical health, and then affect the smooth completion of work tasks.

Laboratory Safety Guidelines

1. We must adhere to the principle of safety and prevention first: all personnel working in the laboratory should be familiar with the "laboratory safety system" and other rules and regulations related to safety, and should master the knowledge of fire safety, chemical dangerous goods safety knowledge and the safe operation of chemical laboratory testing.

2. New personnel who enter the laboratory to do experiments must go through safety education, training and assessment, and only those who pass can undergo laboratory tests.

3. During the experiment, the operator shall not leave the laboratory without authorization, and someone must take care of it when leaving (experiments with safety guarantee and reliable instrument operation can leave for a short time).

4. Smoking is strictly prohibited in the laboratory.

5. Work clothes should be worn when working, long hair should not be shawled, should be tied up, work clothes should not be worn in public places such as canteens, and protective equipment should be worn when carrying out dangerous work.

The importance of laboratory safety is as follows:The laboratory is an important place for experimental teaching, scientific research, and social services. Laboratory safety management has a profound impact on staff.

From the layout of the laboratory, the maintenance of equipment, to the storage of hazardous chemicals, the use of instruments and equipment, safety inspection records, to the management mode and management system of the laboratory, we are required to be rigorous and realistic, keep improving, and cultivate good habits of safety experiments. However, there are many risk factors lurking in the laboratory, and a slight negligence is very prone to safety accidents, which affect our physical health, and then affect the smooth completion of work tasks.

1. Prevent laboratory accidents, protect the personal safety and health of test personnel, and reduce the loss of property and personal life caused by accidents.

2. Establish personal safety awareness, take the initiative to learn knowledge and pay attention to safe behaviors.

The ultimate purpose of laboratory safety management is to establish the most reasonable cost to obtain the maximum safety guarantee, and through the risk assessment, determine the acceptable risk, reduce the risk to a tolerable level, reduce the risk of disasters in the experimental process, and ensure the health and safety of scientific researchers, so as to meet the safety needs of scientific researchers. The importance of laboratory safety management lies in meeting the needs of rapid, healthy and sustainable development of scientific research; Implement the people-oriented concept and cultivate the needs of innovative talents and compound talents; Safeguard the interests of the country and the people, and safeguard their own occupational health and safety.

1.Safety of laboratory items.

Some laboratories have safety problems due to the negligence in the management of a large number of chemically toxic or even highly toxic pesticide standards, organic reagents, drugs, and high-pressure gas cylinders; Due to the insufficient detection area, the items that need to be stored separately are not completely separated, which has potential safety hazards.

2.Safety of laboratory instruments.

In order to meet the requirements of the testing project, the laboratory needs to be equipped with a variety of large-scale precision instruments. The laboratory should have an emergency power system, otherwise if there is a sudden power failure during the use of the instrument, it is easy to cause damage to the instrument and equipment. The fire emergency, anti-static grounding, exhaust facilities, and instrument signs in the laboratory should be complete and effective.

3 .Safety of laboratory inspectors.

Some experiments need to be carried out under the conditions of high temperature, high pressure, strong magnetic microwave and radiation, strong acid and alkali corrosion and toxic gases, and the laboratory is not equipped with good ventilation, exhaust and other safety facilities, and the physical and mental health of the inspectors will be in great danger. As the person responsible for laboratory safety protection, laboratory inspectors should do a good job of safety protection anytime and anywhere, and report the unsafe factors existing in the laboratory in a timely manner for rectification; In case of safety accidents during the experiment, emergency rescue facilities should be equipped.

4.Laboratory emissions are a potential safety hazard to the environment.

In the process of the experiment, a large number of waste liquid, waste gas and waste will be produced, there are expired or invalid organic reagents and strong acid and alkali corrosive drugs, containing a variety of toxic and harmful substances, if not properly treated, such as not meeting the specified emission standards and discharged into the environment (atmosphere, soil, water), it is easy to pollute the environment, destroy the ecological balance and natural resources, in fact, the laboratory has become a pollution source that can not be ignored.

5.Water and electricity safety in the laboratory.

The phenomenon of improper use of water and electricity by experimenters is widespread, especially in laboratories with flammable and explosive drugs. The reasons for the analysis are: 1. Forget to turn off the water and electricity.

2. Improper operation or improper use of the instrument. 3. The power supply line is aging and overloaded. 4. Cigarette butts are also important safety hazards.

5. The anti-virus and explosion-proof facilities are incomplete.

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.

Universities in Hong Kong take laboratory safety very seriously. For example, postgraduate students are required to undergo mandatory safety training and examinations arranged by the Office of Safety and Environmental Affairs of the University before using controlled materials or apparatus. Safety training should also be mandatory for science and engineering undergraduates, including large-scale education and online courses, and general safety training courses such as fire prevention and escape should be offered.

Tsinghua University has developed an online learning and examination system for laboratory safety courses, and uses modern network information technology and rich network information resources to carry out laboratory safety education.

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.

1. Laboratory safety:

Refers to the state in which the laboratory is exempt from an unacceptable risk of damage.

2. The purpose of laboratory safety:

The laboratory is a complex place, often using a variety of chemicals and equipment, as well as water, electricity, gas, but also encounter high temperature, low temperature, high pressure, vacuum, high voltage, high frequency and laboratory conditions and instruments with radiation sources, if the lack of necessary safety management and protection knowledge, will cause huge losses of life and property.

3. Laboratory safety management:

Laboratories should formulate corresponding safety standards for risk factors that may involve electrical, mechanical, non-ionizing radiation, chemical and microbial risks during operation, so as to improve the safety management and safety technology capabilities of the laboratory and reduce the safety risks of experimental operation. Specific means:

1) Formulate strict laboratory safety management regulations.

Safety Measures in Chemical Laboratories (1) Fire Prevention and Fire Extinguishing Flammability in chemical laboratories. Explosive materials need to be inspected regularly, kept away from fire when used, and should not come into contact with strong oxidizing agents. Smoking is strictly prohibited in the laboratory, and it is strictly forbidden to light a fire for heating; Household appliances should be overhauled frequently to prevent short circuit or overload caused by poor insulation.

In the event of a fire, the combustibles should be removed immediately, the power supply should be cut off, and the ventilation should be stopped. For small fires, a damp cloth should be used immediately. Sand and the like cover the combustibles to isolate the air and extinguish the ceasefire.

In the event of a fire, the police should be called immediately, and the corresponding fire extinguisher should be used according to the nature of the combustibles for rescue to reduce losses. Commonly used fire extinguishers are as follows: 1

CO2 fire extinguisher: suitable for appliances**. 2.

Dry powder fire extinguisher: used to extinguish combustible gas, oil, electrical equipment, articles, documents and other initial disasters. Fire extinguisher:

High-efficiency fire extinguishing agent, used in oil, organic solvents, high-voltage electrical equipment and precision instruments. 4.Foam fire extinguisher:

Suitable for oils and general**. (2) Handling of general injury accidents The laboratory is equipped with a medicine box with commonly used medical supplies: Disinfectants:

75% alcohol, iodine, 3% hydrogen peroxide, alcohol cotton balls. Scald medicine: jade tree oil, blue oil hydrocarbons, scald medicine, petroleum jelly.

Wound medicines: red potion, gentian juice, anti-inflammatory powder. Chemical burn medicines:

5% sodium bicarbonate solution, 1% boric acid, 2% acetic acid, ammonia, 2% copper sulfate solution. **Supplies: cotton wool, gauze, wound protection gel, bandages, tweezers, etc.

1. Cut treatment: keep the wound clean, if there is a foreign body in the wound, it should be carefully removed, then cleaned with alcohol cotton, coated with red syrup, and bandaged with anti-inflammatory powder if necessary, and taken to stop bleeding in severe cases and sent to the hospital. 2 Treatment of scalds and burns:

The wound can be coated with eucalyptus oil or 75% alcohol and then coated with blue oil hydrocarbons. If the wound is large and deep into the dermis, it should be carefully treated with 75% alcohol, and bandaged with scald ointment before being taken to the hospital. 3 Chemical burn treatment methods:

If it is stained with concentrated sulfuric acid, do not rinse with water, first use a cotton cloth to absorb concentrated sulfuric acid, then rinse with water, then neutralize with 3% 5% sodium bicarbonate solution, and finally wash with water. Apply glycerin if necessary and, if blisters, gentian juice. As for other acid burns, they can be rinsed immediately and then treated.

If you are burned by alkali, rinse with water and then wash with 3% boric acid or 2% acetic acid. If the acid and alkali of the fruit splash into the eye, it should be rinsed with water first, and then cleaned with 5% sodium bicarbonate solution or 2% acetic acid. (3) First aid measures for poisoningThere are three ways of chemical poisoning:

Poisoning by inhalation of toxic gases, dust, smoke through the respiratory tract; 2 Poisoning by misingeation through the digestive tract; 3 Poisoning through contact**. When poisoning occurs in the laboratory, emergency measures must be taken, and at the same time, emergency treatment must be taken to the hospital, and the commonly used first aid measures are as follows: 1. Respiratory poisoning, the poisoned person should be evacuated from the scene.

Move to a well-ventilated area to allow the patient to breathe fresh air. Mild cases will return to normal sooner.
