How to use the biosafety cabinet :
mainly from person to person through respiratory droplets. Respiratory droplets travel into the air when you cough, sneeze, talk, shout, or sing. These droplets can then land in the mouths or noses of people who are near you or they may breathe these droplets in.
Masks are a simple barrier to help prevent your respiratory droplets from reaching others. Studies show that masks reduce the spray of droplets when worn over the nose and mouth.
You should wear a mask, even if you do not feel sick. This is because several studies have found that people with COVID-19 who never develop symptoms (asymptomatic) and those who are not yet showing symptoms (pre-symptomatic) can still spread the virus to other people. Wearing a mask helps protect those around you, in case you are infected but not showing symptoms.

1, all the items before the operation biosafety cabinet should this operation required into the cabinet, to avoid frequent arms through the air curtain stream damage; and 75% alcohol wipe surface-sterilized to remove the contamination prior to use into.
2. Turn on the fan for 5 to 10 minutes, and then carry out the experimental operation after the air in the cabinet is purified and the airflow is stable. Slowly extend your arms into the safety cabinet for at least 1 minute to stabilize the airflow in the cabinet before operating.
3. Items not related to this experiment are not placed in the safety cabinet. The items in the cabinet should be placed in a clean area, semi-contaminated area and contaminated area. The items are easy to use during operation and there is no intersection between the three areas. Items should be placed as far back as possible, but the airway opening should not be blocked to avoid interference with normal airflow.
4. The operation should be carried out from the cleaning area to the contaminated area to avoid cross-contamination. To prevent possible spills, a towel or gauze soaked with disinfectant can be placed on the countertop, but the safety cabinet grille should not be covered.
5. During the operation of the cabinet, it is strictly forbidden to use an open flame such as an alcohol lamp to avoid the generated heat generating airflow and to interfere with the airflow in the cabinet; and the open flame may damage the HEPA filter.
6. Minimize the movement of people behind the work and quickly switch the door to prevent the airflow in the safety cabinet from being unstable.
7. During the experimental operation, the glass window should not be opened, and the operator's face should be above the working window. When operating in the cabinet, the action should be gentle and soothing to prevent airflow in the cabinet.
8. The biological safety cabinet should be regularly tested and maintained to ensure its normal operation. If the safety cabinet is found to be abnormal during work, stop working immediately, take appropriate measures, and notify relevant personnel.
9. After the work is completed, close the glass window, keep the fan running for 10 to 15 minutes, and turn on the UV lamp for 30 minutes. (Voice should be turned off during UV sterilization; UV light is harmful to the human body, pay attention to personal protection.)
10. The biological safety cabinet should be cleaned and disinfected regularly. The contaminants in the cabinet can be wiped with 2% 84 disinfectant after the work is completed and the UV lamp is disinfected. The outer surface of the cabinet should be wiped with 1% 84 disinfectant per day.
11. Items used in the cabinet should be removed after disinfection to prevent pathogenic microorganisms from being carried out and polluting the environment.
