Guide to waste disposal in biological laboratories
In the process of scientific research, biological experiments will produce a lot of waste. In order to ensure environmental safety and human health, these wastes must be properly disposed of. Therefore, this paper will introduce the classification, treatment methods and matters needing attention of biological laboratory waste in detail.
I. Classification of wastes
1. Ordinary garbage: mainly refers to domestic garbage such as paper scraps generated in experiments.
2. Laboratory organic waste liquid: it mainly includes all kinds of toxic and harmful solvents and reagents produced in the experimental process.
3. Laboratory inorganic waste liquid: mainly including acid-base waste liquid and other inorganic salt solutions.
4. Solid waste: including disposable consumables such as suction heads and centrifugal tubes; As well as experimental animal carcasses and their excretions.
5. Medical waste: mainly refers to sharp instruments (syringes) and infectious articles (inoculation rings) after use.
6. Radioactive wastes: mainly include radioactive sources, radioactive culture media or cell suspensions.
Second, the treatment method
1. Ordinary garbage can be directly thrown into the trash can, but it needs to be stored separately from other types of waste;
2. Laboratory organic waste liquid should be collected centrally and handed over to professional institutions for recycling or destruction;
3. For laboratory inorganic waste liquid, different neutralization methods should be selected according to different pH values before it can be discharged into the sewer system;
4. The plastic products in solid waste can be converted into fuel oil by high temperature pyrolysis to realize resource utilization; The experimental animal carcasses should be incinerated to avoid the spread of the virus.
5. Medical wastes need to be autoclaved in accordance with relevant regulations and finally sent to special medical waste disposal sites for unified disposal;
6. Radioactive wastes must be placed in special containers for decay before further treatment.
Third, matters needing attention
1. Waste must be cleared in time to prevent cross-contamination;
2. When collecting waste, you must pay attention to the protective measures in place to prevent your body from being hurt;
3. Different kinds of wastes should not be mixed together to avoid greater harm;
4. It is necessary to strengthen staff training and improve their understanding of waste management in order to better implement relevant policy requirements.
In short, it is a very important task to do a good job in the management of biological laboratory waste in daily work. Only by arranging each link scientifically and reasonably can we effectively protect the living environment of human beings from being damaged, and at the same time let our research activities be better carried out!
