1. Consider the user's facial features

Close-fitting masks (ie, half masks and full masks) rely on the close contact with the user's face to ensure proper protection. People's faces are various, and each type of design with a close-fitting mask may not be suitable for the owner of labor insurance products, and may leak when worn. How to avoid this situation? Close-fitting face masks usually have different sizes, which can be selected according to the size of the face, but the degree of fit can not be reliably determined only based on the type selection.

Suitability testing is a method to test the suitability of certain types of close-fitting masks for a specific user. The advantage of this is that both protective equipment users and health and safety chiefs can use objective methods to select reasonably-designed products and eliminate the possibility of dangerous leakage. This is particularly important for the selection of negative-pressure respiratory protection products.

Due to the new suitability test method, there are few applications in China, and there are few ready-made inspection products in the market. Starting from the feasibility, the standard uses it as a recommended method for users' reference.

Another factor that needs attention is that men with certain mustaches do not have a close-fitting mask. If you can't persuade them to scrape their beard, they can only choose masks that don't need to be fitted, such as open face masks.

2. Consider people wearing glasses

There are many people who usually wear glasses, so the use of full-face masks can not affect the wearing of glasses, wearing glasses can not affect the closeness of the mask, such as the gasket can not be inserted into the gasket, this will certainly lead to leakage. The best way to solve this problem is to choose a full face mask with a built-in spectacle frame, or choose a hood or an open face mask that does not require close fitting.

3. Some people may not be suitable for respiratory protection

For people with certain disorders of the cardiopulmonary system, the extra respiratory burden will increase their milk-milk heat-resistant gloves; some people will also feel instinctively fearful, have anxiety, or be segregated. The reaction will affect the accuracy of the job and work efficiency, and even affect the danger. The Appendix F of the standard, Medical Evaluation of the Use of Respiratory Protective Devices, describes the factors that should be taken into consideration from the physical and psychological aspects, and helps identify people who are not suitable for use.
