Analysis of hidden dangers in the construction of Fuzhou chemical laboratory

What should be paid attention to in the construction of Fuzhou chemical laboratory ？SICOLAB Xiaobian will come with you to analyze the details of laboratory construction

One 、 Construction of chemical laboratory ： Environmental hazards

① The reagent warehouse is located in the basement , Small area , Damp and dark , Poor ventilation , Stacking of various reagents , It is suggested to transform and expand .

② The atomic absorption chamber is small , Temperature and humidity cannot be controlled , It is unfavorable to the use and maintenance of the instrument , The temperature is high in summer , And store acetylene gas , Explosive . It is recommended to install an independent air conditioner .

③ There are too few existing fume hoods , And the effect is not good , It is far from meeting the existing experimental requirements . It is recommended to install several more fume hoods .

④ Many gas cylinders are used , There is explosive hydrogen gas 、 Acetylene gas , Storage of gas cylinders is not standardized , There is no separate cylinder room . It is recommended to set up a special gas cylinder room , It also has a monitoring and alarm system .

⑤ Inspection room circuit 、 There are many wires , To avoid fire accidents caused by aging lines . It is recommended to organize electricians to inspect regularly .

⑥ When the sample is crushed , It's noisy 、 More dust , And may affect other samples ( Such as identification ). It is suggested to set up a separate crushing room , And install ventilation facilities .

Two 、 Construction of chemical laboratory ： Hidden dangers of instruments and equipment

① The pressure steam sterilizer in the microorganism room is used every week 2-3 Time , There are also faults from time to time . It is recommended to organize maintenance workers to conduct a comprehensive inspection every quarter , To ensure safe use .

② Evaporative light scatterer directly discharges organic gas into precision instrument room , Great harm to the inspector's health . It is recommended to change the position so that the exhaust gas is discharged outside .

③ When the electric furnace is used , Often put the sample on the electric furnace to heat and dissolve at the same time , While the inspector is doing other experiments , It is difficult to avoid the solvent splashing on the electric stove after boiling , Cause fire accident . It is recommended that all electric furnaces be placed in one fume hood , The user pays close attention to .

3、 ... and 、 Construction of chemical laboratory ： Reagent hidden danger

① Flammable for daily use 、 Explosive 、 volatile 、 Toxic 、 Strong corrosive reagent ( Such as : Ether 、 Petroleum ether 、 phenol 、 Bromine, etc ) Store under ventilated kitchen , Electric stoves and water baths are often used in ventilated kitchens , It is difficult to avoid static electricity in high temperature areas 、 spark , There is a risk of reagent explosion . It is recommended to buy a refrigerator to store low boiling point 、 Volatile reagents .

② There are few reagent storage cabinets in the laboratory , The reagents are placed neatly , But it is crowded . It is recommended to buy a professional reagent cabinet .
