How to run your analytical lab safely

Keywords: laboratory safety operation analysis instrument

Laboratory safety is very important. The experimental operation has very strict regulations. Today, we will tell you about the matters needing attention in the experimental operation.
1. Before adding the reagent, mix it to avoid uneven concentration. The frozen reagents must be completely melted before they can be used.
2. The reagent label should be written with the name and date of the formulator. The date must include not only the month and the day, but also the year. Maybe a bottle of reagents will last longer than you did in the lab.
3, plexiglass can not be wiped with alcohol, otherwise it will turn white, blurred.
4. Do not throw the syringe in the ordinary trash can, otherwise there will be big trouble. Do not take the needle out of the needle sleeve and throw the needle with the needle sleeve together with the needle tube in the box for the sharp object collection.
5, enter the animal laboratory to maintain the habit of wearing a mask to avoid suffering from allergies.
6. For women in the laboratory, pay special attention to:
1 It is forbidden to make up and handle contact lenses in the laboratory; it is not recommended to wear jewelry in the laboratory.
2 Long hair must be placed behind the head and tied up to avoid contact with hands, samples, containers or equipment.
3 Do not advocate shoes with short skirts and exposed toes.
7. Women who are encouraged to work in the laboratory should start with the exact risk factors or less exposure (including the man) in the laboratory three months before the planned pregnancy, and conduct tests on prenatal and postnatal care. If you have a pregnancy and have a history of exposure to risk factors during pregnancy, you can receive TORCH in early pregnancy (within 3 months of pregnancy), Down's screening within 16 to 20 weeks of pregnancy, and ultrasound examination after 4 months of pregnancy. The fetus has obvious congenital malformations. Regular obstetric examinations and ultrasonography can be used to understand the growth and development of the fetus. The human teratogenic artifacts commonly found in laboratories today:
1 Chemicals: methylmercury, polychlorinated biphenyl (PCB), 2,4‐D‐dioxin insecticide, benzene, xylene, toluene.
2 microbial infection: viruses (rubella virus, cytomegalovirus, varicella virus, herpes simplex virus, herpes zoster virus, treponema pallidum, human immunodeficiency virus, etc.).
3 physical factors: radioisotope and other ionizing radiation.
4 If animal experiments are carried out, attention should be paid to the possibility of animals carrying and infecting microbial infections.
5 The effect is not only in pregnancy, but during the lactation period after delivery, some teratogens can also be delivered to the baby through breast milk, so that the baby continues to accumulate certain poisons and damage growth and development.
6 The effect of teratogens on fertility depends on how much contact, exposure dose and length of exposure. Personal protection measures are especially important.
