Original title: @ epidemic prevention and control volunteers, you must understand these job classifications and protection points! Recently Many volunteers are fighting on the front line. Assist schools, communities or related units Carry out epidemic prevention and control work In the auxiliary nucleic acid testing, community sealing and control of material delivery, etc. Contribute to each position But While actively participating in epidemic prevention and control Volunteers must also strengthen their self-protection. Now let's take a look. Division standards and control measures for sealing control area, control area and prevention control area As well as the classification of volunteers for epidemic prevention and control and the key points of protection. Expand the full text 1 Sealing control area, control area, prevention and control area Classification standards and control measures 2 Classification of volunteers for epidemic prevention and control and key protection points Category I: administrative or auxiliary Service volunteer protection It can be carried out in low-risk areas or prevention areas. Attention should be paid to wearing surgical mask in indoor multi-person scenarios without special protection requirements. Volunteers engaged in material handling should also wear gloves and carry hand disinfectants. Class II: prevention area (Nucleic acid test assistant volunteers) Keep a social distance from the sample; Disinfect hands frequently; Personal protective equipment of the same level as the medical staff shall be worn when assisting in the sampling operation area (it is recommended to wear disposable work cap, medical protective mask, protective face screen/goggles, medical protective suit, disposable gloves and shoe covers); Other nucleic acid detection AIDS (such as scanning code registration, etc.) It is recommended to wear disposable work cap, N95 or KN95 particulate matter protective mask/medical protective mask, isolation clothing, disposable gloves, work cap, and waterproof work shoes. It is recommended to wear protective face screen or goggles when working continuously for more than 2 hours. Class II: prevention area (Volunteers assisting in building sweeping, scanning code registration, etc.) Disinfect hands in time after touching elevator buttons, door handles, doorbells and other items; Avoid entering the home of the isolated person or having close contact with the isolated person; Control the number of people when taking the elevator to avoid crowding; Pay attention to keeping social distance with clients; Disinfect hands in time after contacting personal belongings of service objects; It is recommended to wear N95 or KN95 particulate respirator/medical respirator, isolation clothing, disposable gloves, work cap and waterproof work shoes. Category III and IV: controlled and sealed area (Nucleic acid test assistant volunteers) Keep a social distance from the sample; Disinfect hands frequently; Personal protective equipment of the same level as the medical staff shall be worn when assisting in the sampling operation area (it is recommended to wear work clothes, disposable work caps, medical protective masks, protective face screens/goggles, medical protective suit, disposable gloves and shoe covers); Other nucleic acid detection AIDS (such as scanning code registration, etc.) It is recommended to wear work clothes, disposable work caps, medical protective masks, protective suit (confirmed cases) or isolation clothing (tight connection), disposable gloves, work caps, shoe covers, and protective face screens or goggles as required. If the operation lasts for more than 2 hours, it is recommended to use medical protective suit.

If the materials are transported to the building where the isolated object resides, it is recommended to wear the personal protective equipment of the same level as the young volunteers who sweep the building, namely, work clothes, disposable work caps, medical protective masks, protective suit (confirmed cases) or isolation clothes (tight joint), disposable gloves, Medical Disposable Coverall ,Full Body Disposable Coverall, work caps and shoe covers.

Young volunteers are limited to support work in the clean area. If it is really necessary to enter the contaminated area due to special circumstances, please use, wear and take off the medical protective suit, gloves, medical protective masks, shoe covers and other personal protective equipment that meet the requirements of the contaminated area protection registration under the guidance of professionals; Do not leave the closed-loop or contact with external personnel during work; When working in the clean area, you should wear a medical surgical mask and wash your hands/disinfect your hands at any time.
