What Are The Places Where Chemical Laboratory Construction Programs Need Attention?

May 25, 2018

What BOKA wants to update for everyone today is the construction of a chemical laboratory. After the various laboratory building plans were released, many customers would respond. The construction of the laboratory and the initial laboratory construction plan will be a bit tricky. In and out, here the VOLAB Xiaobian wants to explain to everyone that the laboratory construction plan that was released before is generally a preliminary rendering. In the construction of the laboratory, it will inevitably lead to other problems and have to change the original plan. This leads to an inconsistency between the renderings and the actual results, which will produce a certain gap. This phenomenon is normal ~~

Chemical laboratory rooms can be roughly divided into three categories: precision instrument laboratories, chemical analysis laboratories, and auxiliary rooms (offices, storage rooms, cylinders, etc.).

1. The Precision Instrument Room precision instrument room is required to have the functions of fire prevention, shockproof, electromagnetic interference prevention, noise prevention, moisture resistance, corrosion resistance, dust prevention, and prevention of harmful gas intrusion. The room temperature should be kept as constant as possible.

2. Analytical laboratory conducts chemical treatment and analysis of samples in the chemical analysis room. Some small electrical equipment and various chemical reagents are often used in the laboratory. If the operation is inadvertent, it also has certain risks. The chemical laboratory is used for these characteristics. The design should be that the building should be fire resistant, the material should have fire resistance; the windows should be dustproof; the indoor lighting should be better; the doors should open outwards.


Chemical laboratories are inseparable from dangerous chemicals.

According to the hazardous characteristics of chemicals, China classifies hazardous chemicals into 8 categories. VOLAB Xiaobian is here to give you a brief explanation.

1Dirty explosives can undergo violent chemical reactions under the influence of external influences (such as heat, pressure, impact, etc.) and instantaneously generate a large amount of gas and heat to explode. Generally contains the following structure: 0-0 (peroxide), 0-C1 (gas acid or peroxyacid compound), N-X (halogen halide), N = 0 (nitro or nitroso compounds), N=N (pile or heavy gas compound), N=C (rareate compound), C^C (acetylene compound, etc.).

2 Compressed gases and liquefied gases Cylinders such as acetylene, hydrogen, oxygen, and nitrous oxide.

3 Flammable liquids Closed cup test Liquid with a flash point equal to or lower than 61 T.

4 Flammable solids, pyrophoric articles, and flammable articles that are wet, such as alkali metal hydrides, calcium carbide, white phosphorus, etc.

5 oxidants and organic peroxides.

6Drugs with oral solid LD 5{)* <500 mg/kg, liquid LD50<2000 mg/kg; LD 50< 100 mg/kg after skin contact for 24 h; dust, fumes, and vapors Human LC5Q <10 mg/L solid or liquid.

7 The radioactive specific activity of radioactive articles is greater than 7. 4X l0 4Bq/kg items.

8 Corrosion products are solids or liquids that can burn human tissue and cause damage to metal objects.

Chemical laboratories have always had a high degree of danger. Because there are a large number of dangerous goods, the chemical laboratory construction program must find professional personnel to carry out design and reconstruction, and must not carry out their own independent work.
