Many of the chemical reagents and laboratory reagent solution varieties, chemicals are toxic and dangerous, to strengthen its management is not only to ensure the quality of analytical data, but also the need to ensure the safety of the.
Laboratory is only suitable for the use of a small amount of short-term domestic demand. Chemical reagents according to the inorganic, organic and biological medium classified storage, inorganic acid, alkali and salt according to classified storage, according to the order of the active metal salts classified storage, biological medium stored in bacteria culture of different classification, which belongs to the hazardous chemicals in the toxic drugs should be locked in the special cabinet in the lock by hand, led by the implementation of custody application and approval, double sign system.
One, belong to the chemical reagents of dangerous goods
1 explosive and unstable substances. Such as the concentration of hydrogen peroxide, organic peroxide, etc..
2 oxidizing substances. Such as oxidation of acid, hydrogen peroxide is also such.
3 combustible material. In addition to flammable gases, liquids and solids, is also included in the moisture will produce combustible material. Such as white phosphorus substances such as alkali metal hydride, calcium carbide and contact air combustion.
4 toxic substances.
5 corrosive substances. Such as acid, alkali, etc..
6 radioactive material.
Two, laboratory chemical reagents storage, use requirements
1 flammable reagents should be stored in safe (more than 1mm thickness), the top cabinets have vents. Is strictly prohibited in the laboratory storage of more than 20 L of bottled flammable liquids. Flammable and explosive drugs should not be placed in the refrigerator (except for explosion proof refrigerator).
Two after mixing or contact with each other can produce intense reaction, combustion, explosion, release of toxic gases of 2 or more than two kinds of compounds known as incompatible compounds, can not be mixed. The compounds are mostly strong oxidizing and reducing substances.
3 the corrosive agent should be placed in the plastic or enamel tray or barrel, in case the accident caused by the rupture of the bottle.
4 to pay attention to the duration of the chemical drugs, some reagents in the process of storage will gradually deteriorate, and even harm.
5 the medicine cabinet and reagent solution should avoid direct sunlight and close to the central heating and other heat source. Light requirements reagents must be packed in brown bottle or black paper or cloth wrapped in dark cabinet.
6 found that the reagent bottle on the label dropped or will be blurred when the label should be posted immediately. No label or label can not be identified as a risk of identification of the reagents should be re identified after careful handling, can not be casually throw, so as not to cause serious consequences.
7 chemical reagents positioned and reset, saving the use of after use, but extra chemical reagents are not allowed to fall back to the original bottle.
