Detailed Description:
1 Overall designThis study uses the methods of cross-sectional survey and chance sampling
2 Sign the Informed Consent Form
3 Investigation on the basic situation of personnel The gender age and education level of the subjects were analyzed as the factors influencing whether the mask was worn correctly or not
4 Investigation on the types of wearing masks 1 The types of masks worn by the subjects were recorded as the basis of stratified statistics
2 Mask suitability testing
1 Visual inspection whether the mask is close to the face with obvious gaps
2 Breathing test Are there any obvious gaps or whether the cotton around the mask is blown when the subject taking a deep breath
3 Spray test The FT-30 qualitative fitness test system of 3M company was used to test the suitability and correctness of wearing mask
In the spray test all subjects underwent a sensitivity test to prove their ability to smell the bitterness of the reagent sensitive subjects can participate in the direct spray test
In order to objectively reflect the overall situation of the subjects it is necessary to cover many ages and educational levels of men and women
