How to take effective measures to prevent biosafety incidents

Answer 1

The following are some effective measures to prevent biosafety incidents:

** 1. System and Awareness Level **
1. ** Strengthening Awareness of Laws and Regulations **
- The relevant units and personnel should actively implement the spirit of laws and regulations such as the Biosafety Law of the People's Republic of China and the Regulations on the Biosafety Management of Pathogenic Microorganism Laboratory. This will help regulate biological activities at a macro level and prevent the occurrence of biosafety incidents.
2. ** Raise risk awareness **
- The relevant personnel should establish a sense of biosafety risk. Whether it was in the laboratory, customs quarantine, or disease prevention and control, they should start from the subtleties and always maintain vigilance against biosafety incidents.

- The enterprise must earnestly fulfill its main responsibility, strengthen safety management, and strictly abide by relevant laws, regulations, standards, and norms. Everyone should also raise their safety awareness and abide by the safety operating procedures.

** II. Personnel Training and Emergency Management **
1. ** Strengthening personnel training **
- Training for biosafety related staff. For example, the Center for Disease Control and prevention can provide biosafety professional technical training for employees to familiarize them with biosafety management systems and emergency response procedures for laboratory biosafety incidents, focusing on laboratory biosafety risk identification, risk assessment, and handling methods for various safety incidents.
2. ** Perfect the emergency management system **
- The relevant units should update and improve the system and plan system, and implement "one case per case" for biosafety incidents to ensure that there are countermeasures to be followed when the accident occurs.
- It was necessary to strengthen biosafety training and emergency drills, and to make biosafety drills a regular practice so as to improve emergency response capabilities.

** 3. The specific operational aspects **
1. ** Laboratory related precautions **
- ** Personal Protection **
- Before entering the laboratory, the staff had to remove their jewelry, trim their nails, tie up their long hair, and not wear open-toed shoes. Always wear suitable lab clothes in the laboratory (such as long-sleeved, back-opening isolation clothes and one-piece clothes when working in the microbiology laboratory and biosafety cabinet), and do not wear protective clothing outside the laboratory. Do not put on makeup or operate contact lenses in the laboratory work area. Laboratory protective clothing and daily clothing should be stored separately.
- During the general work in the laboratory, especially when dealing with infectious substances, blood, and body fluids, disposable surgical gloves made of Latex, Vlene, or Poly-Nylene materials should be widely used. In experiments that may come into contact with sharp instruments, stainless steel mesh gloves should be worn (but it should be noted that they can only prevent cutting damage, not needle damage). Reusable gloves should be properly rinsed, removed, cleaned, and disinfected. When carrying out dangerous experiments, you must wear goggles and masks (goggles should be worn outside conventional vision correction glasses or contact lenses). When cleaning up the spilled infectious substances and other operations with high risk of contamination, you must use gas masks. Different types of gas masks should be selected according to the type of danger and the filter should be checked and replaced in time.
- ** Operation process **
- Carry out the work strictly according to the operation manual. For example, in the process of biological experiments, comply with the relevant regulations on biological pollution prevention, and dispose of the experimental waste according to the medical waste disposal process.
- They should wash their hands before and after contact with microorganisms or experimental animals. They should also wash their hands after removing gloves, before and after using the bathroom, and before leaving the laboratory.
- ** Emergency response **
- In the event of an accident, such as a pricking wound or a cut caused by a needle, wash the wound immediately with soap and a large amount of flowing water, squeeze out the blood from the injured part as much as possible, and disinfect the wound with 70% alcohol or other disinfectant; if the skin is contaminated, wash the contaminated part with water and soap, and soak it in appropriate disinfectant; if the mucus membrane is contaminated, wash the contaminated part thoroughly with a large amount of flowing water or normal saline; if the clothes are contaminated, take off the contaminated clothes as soon as possible and disinfect them; When the contamination splashed, the small-scale contamination should be disinfected immediately, and the large-scale contamination should be notified to the laboratory supervisor and the person in charge of safety to arrive at the scene of the accident to investigate the situation and determine the disinfection procedure; If there is a major splashing accident in the laboratory, evacuate personnel from the contaminated place (to prevent the spread of pollution), control the pollution, lock the door, inform the laboratory supervisor, safety director, etc. to find out the situation and determine the disinfection process. Under appropriate circumstances, the biological safety cabinet and/or the laboratory can be disinfected with low-temperature steam formalin gas (but the biological safety cabinet and/or the laboratory must have reliable sealing performance, and the personnel must leave completely).
2. ** In terms of customs and quarantine **
- The customs should strictly check the imported biological goods and check the declaration information. For example, when checking the ornamental crabs, they should check whether the specifications and varieties of the goods conform to the relevant list of aquatic animals to prevent the introduction of foreign species and avoid potential threats to the ecological security and biological security of our country.
