According to the introduction of the new coronavirus transmission route released by the World Health Organization, we can know that the main transmission route of SARS-CoV-2 virus is respiratory droplet transmission and contact transmission, but in a relatively closed environment, it can also be transmitted through air Sol spread. Unlike droplets, aerosols can float in the air for a period of time and can reach greater distances. This is very dangerous.
How to reduce the spread of COVID-19?
For the first time, it is necessary to strictly control the source of infection and cut off the transmission route. Secondly, it is one of the most effective and economical measures for ordinary people to reduce their going out. When you must go out, you can control it from different aspects to reduce the chance of being infected.
1. Maintaining good hygiene habits can effectively reduce the risk of contact transmission. Wash hands with hand sanitizer or alcohol daily to kill direct or indirect contact sources of infection.
2. For droplet transmission, wearing masks and protective masks correctly and maintaining a safe distance is the easiest and most effective way.
3. For aerosol transmission, ordinary methods cannot achieve good results. The best way is to properly ventilate, renew the air in the room, and reduce the possibility of aerosol spread by installing aerosol adsorbers and air sterilizers in the room.
How can laboratory personnel protect their health?
The working environment of laboratory personnel is more complicated than daily life. They not only face the risk of aerosol infection, but also the strong acid, strong alkali and toxic gases generated during the experiment are also threatening the safety of laboratory researchers at all times. At this time, laboratory personnel should be equipped with personal protective preparations.
Personal protective equipment, often referred to as PPE, refers to equipment used to form a barrier to protect users from any hazards present in the workplace. Not wearing PPE properly can endanger not only your own life, but your workplace and those around you.
In addition, some laboratory protective products can also largely protect laboratory personnel from the hazards of strong acids, alkalis and toxic gases.
1.FUME HOOD
In most laboratories, the Fume Hood is the primary control device for protecting laboratory operators from toxic and hazardous chemicals. At the same time, the Fume Hood can also protect against sudden fires, explosions and chemical splashes at the minimum operating height.
2.LAMINAR FLOW CABINET
Laminar flow cabinet is to protect the experimental material, to create a local high cleanliness air environment, the main role is to ensure the accuracy of the experiment in the operating area, but it cannot provide protection for environment and operator.
3.BIOLOGICAL SAFETY CABINET
Biological safety cabinets (BSCs) are designed to protect the operator, the laboratory environment and work materials from exposure to infectious aerosols and splashes that may be generated when manipulating materials containing infectious agents, such as primary cultures, stocks and diagnostic specimens.
