Laboratory is where colleges and universities carry out talent training、A necessary place for scientific research and social service activities，The safety of the laboratory is crucial to the safety and stability of the entire university。

In order to reduce the occurrence of safety accidents，Enhance everyone’s awareness of safety and environmental protection，Effectively identify sources of danger，Has rich experience in dealing with dangerous accidents，Innovation and Entrepreneurship College2023Year12month5Organize a safety education meeting on the day。This safety education meeting introduces laboratory safety regulations and precautions to laboratory members of the Institute of Innovation and Entrepreneurship。

1. A certain amount of fire-fighting equipment must be stored in the laboratory，Fire-fighting equipment must be placed in a conspicuous location for easy access，All personnel must take good care of fire-fighting equipment，Learn to use，And check and replace regularly as required。

2. Everything stored in the laboratory is flammable、m88 online bettingExplosive items (such as，Hydrogen、Nitrogen、Oxygen, etc.) must be connected to the fire source、Keep the power supply at a certain distance，Don’t pile it up randomly。flammable during use and storage、Explosive materials laboratory，Strictly no fireworks。

3. It is strictly prohibited to stack items in the corridors of the building，Ensure smooth fire access。

NO.02Laboratory Electricity Safety

1. Don’t connect or pull wires randomly，Use electricity without overloading，Do not use high-power electrical appliances；

2. There should be no exposed wire ends in the laboratory，It is strictly forbidden to use metal wire instead of fuse；Do not pile items in the power switch box。

3. Electrical equipment and wiring、Plugs and sockets should be checked frequently，Stay in good condition，Discovered that may cause sparks、Short circuit、Heat and insulation damage、In case of aging and other conditions, an electrician must be notified for repair。

NO.03Technical Security

1． Laboratory staff and students before conducting experimental operations，Receive laboratory safety education in advance，While conducting safety education，Warn the consequences of not following the operating procedures。Laboratory staff and students must strictly follow the equipment and experimental operating procedures to perform experimental operations。

2． For pressure vessels、Strong electricity、Driving、flammable、Explosive、Laboratory for experiments on toxic substances，Should be in accordance with relevant national and school regulations，Develop safety work rules for this laboratory。Those who engage in the above experiments must receive safety technical training，Only those who pass the assessment can operate independently。

3． Laboratories must do a good job in labor protection，For high temperatures、Low temperature、Radiation、Germs、Noise、Toxicity、Laser、m88 online sports bettingDust、Ultra-clean and other environments that are harmful to the human body，We must effectively strengthen the supervision of laboratory environment and labor protection。

NO.04 Laboratory Radiation Safety

1． Purchase radioactive sources、When isotope reagents and ray devices，You should first apply to the school，After review and reporting to the Security Department for filing and approval，Apply to the government environmental department“Purchase permit”, only then can the purchasing department be entrusted with purchasing.

2． Radioactive waste generated from isotope experiments (including isotope packaging containers)，Do not dispose of as ordinary garbage without authorization。Must declare to school，With the consent of the school，The school will ask a qualified company or unit to conduct unified disposal。

3． Each source unit should be equipped with necessary protective equipment and monitoring equipment，Establish and improve the safety inspection system，Radioactive isotopes regularly used in various laboratories、Safety inspection of radiation devices and radiation workplaces，And keep records。Relevant laboratories should regularly check the contamination status of radiation surfaces，And keep records。Test records must be properly kept，Accept inspection and supervision by the school laboratory safety management department and superior departments。

4． Laboratory radiation work sites must be equipped with anti-theft devices、Fireproof、Leakage prevention facilities，Ensure the safety of use of radioisotopes and ray devices。Isotope packaging container、Equipment containing radioactive isotopes、Ray device、Radiation warning signs and work signals must be placed at the entrance to the radiation work site。

Major safety accidents in laboratories

1.Cause of fire accident:Forgot to turn off the power, As a result, the equipment or electrical appliances are powered on for too long and the temperature is too high,m88 bet loginCausing fire；Careless operation or improper use，Expose the fire source to flammable substances，Causing fire；Aging power supply lines，Overload operation, Causing line heating, Cause a fire; throw cigarette butts, Contact with flammable substances, Cause fire etc. The occurrence of such accidents is common,It can happen in any lab.

2.Cause of explosion accident:Violation of operating procedures，Ignite flammable items，In turn causing an explosion；Old equipment，There is a fault or defect，Cause leakage of flammable and explosive items，Explosion caused by sparks。Such accidents often occur in laboratories with flammable and explosive materials and pressure vessels。

3.Cause of biosafety accident:Omissions and accidents in microbiology laboratory management can not only lead to infection of laboratory workers,It can also cause environmental pollution and large-scale population infection；The waste produced by biology laboratories is even more dangerous than that of chemistry laboratories，Biological waste contains infectious germs、Virus、Chemical pollutants and radioactive hazardous substances，May cause great harm to human health and environmental pollution。

4.Cause of poisoning accident:Violating operating procedures by bringing food into a toxic laboratory, causing accidental ingestion poisoning；Old equipment and facilities，There is a fault or defect，Resulting in leakage of toxic substances or failure to discharge toxic gases, Leading to poisoning; poor management, Causing toxic substances to scatter and lose，Causing environmental pollution；The wastewater discharge pipeline is blocked or damaged,Causing toxic wastewater to flow out without treatment，Causing environmental pollution。Such accidents mostly occur in chemical engineering laboratories with chemicals and highly toxic substances and laboratories with toxic gas emissions。

Laboratory safety accidentEmergency handling precautions

m88 sports bettingWhen an accident occurs，To determine the type of accident，Dial the corresponding alarm number in time，And immediately report to the school security office and laboratory equipment management office:

1.When calling for help, please state:

①Accident location;

②Nature and severity of the accident;

③Your name, location and contact number.

2.When an emergency occurs, the following priorities should be followed:

①Protect personal safety, that is, my own safety and the safety of others;

②Protect public property;

③Save academic data.

3.Important phone number:

①Fire alarm phone number:119；

②Police phone number:110；

③Medical emergency:120。
