How to select masks for different groups of people
1 High-risk exposure to use medical protective masks (N95, such as: 3m1860, 1860s or 9132)
High-risk exposure to the danger of the personnel:
1 Medical institutions, medical personnel, fever clinic, isolation hospitalization wards, isolation of the intensive care ward, the need to carry out respiratory specimen collection personnel. The personnel who need to collect respiratory specimens.
2 120 emergency personnel: transportation of confirmed or suspected cases.
3 Staff: staff who need to enter the area of the healthcare facility where the suspected or confirmed patient is located for cleaning, body disposal, inspection and supervision.
2 Use of other particulate matter protective masks (e.g. labeled N95, kN95, FFP2) by persons at higher risk of exposure
Persons at risk of higher risk of exposure:
1 Examining healthcare workers at the gate: taking temperatures, and coming into close contact with patients with relevant symptoms.
2 Medical personnel in medical institutions: pre-screening and triage, blood transfusion, fever clinic registration and issuance of medication, radiography, the use of confirmed or suspected patients laboratory specimens of medical personnel.
3 Home isolation or isolation point on the medical staff
4 other field staff: the need to enter the medical institution or isolation observation place of work, but not in direct contact with the patient.
3 Use of medical surgical masks by persons with moderate risk of exposure
Persons at risk of moderate risk of exposure:
1 Medical personnel at the entrance to the examination (excluding the measurement of temperature and close contact with patients with relevant symptoms)
2 Medical personnel in healthcare facilities: general outpatient clinics, medical personnel in general wards
4 Personnel with a lower risk of exposure Use of disposable medical masks
There are lower risk masks protective utility ranking: medical protective masks, medical surgical masks, general medical masks, general masks.
