How to strengthen the laboratory biosafety management

1 Strengthening safety facilities All facilities, equipment and materials in the laboratory should comply with national requirements and standards, and the hospital management should listen to the advice of the head of the Laboratory Department to provide adequate biosafety equipment. According to the requirements of the laboratory to install biosafety and work in line with the requirements of class II or III biological safety cabinet, negative pressure hood, autoclave, eyewash. Biosafety cabinet installation requirements away from the entrance of the contaminated area and the area where people frequently walk around, the contaminated area should be set up with disinfection devices, there is an independent exhaust system to ensure that the direction of airflow in the laboratory is from the clean area to the contaminated area, but also to ensure that the laboratory air can only be discharged through the high efficiency filtration through the special exhaust ducts. First aid supplies or first aid kit should be set up in the laboratory to cope with occupational exposure and emergencies.

2 biosafety isolation system and personal protective equipment First of all, the laboratory staff should be limited to authorized personnel when entering, and secondly, the laboratory should be clearly separated into clean, semi-contaminated and contaminated areas, and buffer rooms between the area and the area. It should be ensured that the level of protection of the technical test area is controlled within the corresponding assessed risk range, ensuring adequate ventilation and preventing the spread of potentially infectious agents and hazardous gases, and preventing risks from entering the surrounding community. Internationally recognized hazard signage should be present at each entry and exit point of the laboratory. Establish records of tests and develop appropriate operating procedures and management documents. Strengthen personal protection. Personal protective equipment mainly includes: coveralls, isolation clothing, protective clothing, work caps, masks, gloves, respiratory protection devices and positive-pressure gas supply overalls, etc., to prevent accidents.

3 do a good job of sample collection and reception and waste disposal in the laboratory work, sample collection, reception of improper methods, can make the relevant personnel caused by infection and environmental pollution, laboratory - must be strictly formulated out of the relevant SOP standardized management documents. Sample containers should be used leak-proof, lidded, sturdy, safe containers. Receiving specimens should be in a dedicated room, and to establish a specimen receiving registration records. Laboratory waste is a potential source of biological contamination in the hospital. Waste is divided into: pathological waste, drug waste, infectious waste, chemical waste and injurious waste, which contains a large number of bacteria and viruses, with strong toxicity and corrosiveness, a little improper handling, easy to trigger biological pollution, resulting in serious consequences. For this reason, the treatment of waste should be handled by specially trained personnel who are responsible for the collection of waste in a categorized manner. The strict implementation of sealing, marking, aseptic standardized management principles, in accordance with the specified time and route transported to the designated location, by a person for incineration.

4 Laboratory personnel training is the prevention and control of laboratory infections - an important link, the strict establishment of various operating standards, personal behavior, good housekeeping standards and the norms of clearing, disinfection, sterilization after the experiment, so that the staff from the ideological awareness of the importance of biosafety, biosafety prevention is implemented into the work of every day. All personnel should be familiar with the procedures performed after occupational exposure, various emergency medical treatment measures. Can also choose a strong sense of responsibility, high business level for relevant targeted training to strengthen biosafety awareness and basic skills, so that he becomes a qualified biosafety backbone personnel, the existence of the laboratory biosafety management work to guide, supervise and control.
