What are the consequences of laboratory safety accidents

Tsinghua University

On February 28, 2004, the hydrothermal reactor explosion in the Shaw Technology and Science Building occurred. The cause of the accident was the illegal use of a high-temperature heating furnace; the reactor was poorly manufactured and had poor safety.

On May 26, 2001, a graduate student washed lithium metal (about 5 grams) that had been in the glove box for a long time in a pool, causing it to burn and explode. , the pool was blown to pieces, furniture was damaged, and door and window glass was shattered.

Nanjing University

At around 2 pm on February 15, 2012, a formaldehyde leak occurred on the 6th floor of the Chemistry Building on the Gulou Campus of Nanjing University, and about 200 teachers and students were evacuated. Three police cars and four fire engines rushed to the scene. In the accident, many students suffered from sore throats, tears, and felt unwell.

Lanzhou University

At 19:34 on April 7, 2009, an ammonia gas leak occurred in No. 515 of the Chemistry Laboratory of Lanzhou University.

Nankai University

At about 11 a.m. on December 7, 2011, a girl from Nankai University had an accident while doing a chemical experiment. The head was seriously injured.

Central South University

At 12:59 noon on October 10, 2011, a fire broke out on the fourth floor of the laboratory building of the School of Chemical Engineering of Central South University.

Jinan University

On the afternoon of June 21, 2011, a glass instrument explosion occurred in an experimental teaching building of Jinan University. A girl was injured in the face. Fortunately, the girl was rushed to the hospital in time and the broken glass in her eye was removed in time.

Sichuan University

At about 15:45 pm on April 14, 2011, three students in Laboratory 1, School of Chemical Engineering, No. 103, Building B, First Experimental Building, Jiang'an Campus, Sichuan University were working During the normal pressure fluidized bed coating experiment, the experimental materials accidentally exploded and three students were injured.

Zhejiang University of Technology

At 9:31 pm on May 25, 2010, a student at Zhejiang University of Technology on Chaowang Road accidentally caused a fire while doing chemical experiments in the classroom. , the fire was relatively large and some students were trapped. When we were still more than 100 meters away from the school, we smelled a pungent burning smell, but no open flame was seen. The fire was in the chemical engineering building on the west side of the campus, and a large amount of thick smoke came out of the building.

Capital Normal University

On August 8, 2005, a fire broke out in a laboratory on the second floor of the laboratory building of the Department of Chemistry of Capital Normal University. There were no casualties.

What is the scope of application of emergency rescue plans for laboratory safety accidents caused by artificial carelessness

p>

What is the scope of application of the emergency plan?

If it is a comprehensive plan, it is applicable to the work and homework in your laboratory! If your plan does not include weather, anti-terrorism and riot prevention, environment, drug leakage, etc., then it only applies to laboratory safety production.

If it is a special plan, you have to separate it. Plans for fires and electric shocks are applicable to the entire laboratory. Mechanical injuries are generally those with mechanical performance testing machines, and poisonings are those with hazardous chemicals and pharmaceuticals. Anyway, the plan must be targeted and have risk analysis, and the scope of application of the plan must be determined according to the risk area.

I hope it can help you learn lessons from the experience. Laboratory safety accidents occur frequently. How to reduce safety?

For laboratory construction, choose an experienced company and pay attention to abide by the experimental rules. Henan is advertised as a laboratory What are the causes of laboratory electrical accidents and biosafety accidents

Common electrical accidents are related to wiring methods. Here are a few common ones: aging and fire, short circuit, overload, open circuit, and virtual connection. Liquid or other corrosive solutions enter the power strip

What are the safety accidents that are easily caused in daily life?

Fires, car accidents, children swallowing jelly and getting stuck, going out to take out the garbage and being locked outside while the gas is turned on at home, the outdoor unit of the air conditioner falling and hitting people due to man-made reasons, etc. What are the equipment in the food testing laboratory safety testing laboratory

Clean table, incubator, autoclave, sterilizer, electric furnace, gas chromatography-hydrogen flame detector, liquid chromatography-UV/visible light detector , atomic absorption meter-graphite furnace detector, atomic fluorescence, gas chromatography-mass spectrometer, which safety accidents may occur in the laboratory

lt; divgt; B lt; divgt;

Question analysis: A is an incorrect operation. The label is not facing the palm of the hand, which will cause the label to be corroded; the bottle stopper is not turned upside down, which will cause contamination of the reagent, but neither situation will cause a safety accident. Therefore A does not choose. B is the answer. Doing so will cause the alcohol in the alcohol lamp above to spill out and cause a fire. So choose B. Operation C is also wrong. Doing so will open up the bottom of the test tube, but it is not considered a safety accident. D has two mistakes. One is that the filtrate does not flow along the glass rod into the funnel, which may spill the filtrate outside the funnel; the other is that the lower opening of the funnel is not close to the inner wall of the beaker, which may cause the liquid to splash out of the beaker. Although it is wrong, it will not cause a safety incident. What policies does the country have regarding laboratory safety?

The "Testing Laboratory Safety" standard is still being formulated, but the opinion draft can be downloaded online. If not I can send you a copy! What are the laboratory safety management rules and regulations? Laboratory management system

Laboratory technician locker room rules and regulations

1. Laboratory work must adhere to the principle of "safety first, prevention first" and strengthen safety education for all teachers and students participating in experiments; each laboratory should establish and improve operating procedures, theft prevention, and fire prevention according to their respective work characteristics. , accident prevention management rules and other rules and regulations, formulate specific requirements and measures, post them in conspicuous places, and strictly implement them.

2. The experimenter of each laboratory is the person responsible for the safety of the laboratory. His responsibilities are: to assist the laboratory director in safety protection work, and to respond to operations that do not comply with regulations or are detrimental to safety. Supervise the factors, have the right to stop operations that hinder safety, and educate and criticize violators. During holidays and specified times, laboratory fire prevention and anti-theft safety measures must be comprehensively inspected and implemented, and safety hazards discovered must be reported and resolved in a timely manner.

3. All kinds of experimental instruments and protective devices must be kept in good condition, and safety devices are not allowed to be modified at will. Precision and valuable instruments and large devices must be operated and managed by dedicated personnel, and unauthorized operation or disassembly is not allowed without approval. Pay attention to waterproofing, dustproofing and rustproofing, and maintain good ventilation.

4. The water and electricity facilities in the laboratory must be installed in accordance with regulations. Overloading of electricity is prohibited, and temporary wiring and grounding are not allowed.
