China standard GB2626-2006 refers to the common KN95 mask standard, and the medical KN95 mask standard is GB 19083-20 10. Medical N95 masks need to prevent high-pressure liquid from splashing, so the standard is higher than that of ordinary N95.
Similarly, ordinary people and medical personnel who are not exposed to high-pressure liquid splashing can use ordinary KN95 masks. During the epidemic, minimize going out, keep a distance of more than one meter from others, wash your hands frequently and disinfect frequently.
GB2626-20 19 usually refers to respiratory protection-self-priming and filtering particulate respirator, which can prevent novel coronavirus. Novel coronavirus is usually transmitted by respiratory droplets, contact and aerosols. It is recommended to wear a mask when going out every day and do a good job of protection.
Based on:
According to the Technical Guide for Selection and Use of Masks to Prevent Infection in novel coronavirus, it is suggested to choose medical protective masks. However, it should be noted that if you are engaged in the first aid of infected patients, tracheal intubation, bronchoscopy and other work, you need to wear goggles or protective screens.
When there is a shortage of medical protective masks, you can choose an anti-particle protective mask that meets the standards of N95/KN95 and above, or you can choose a self-priming filter mask with filter cotton (full face or half face) to prevent particles, and the power filter mask has better protection effect.
Therefore, the respiratory protection-self-priming filter type anti-particle mask can prevent novel coronavirus, and it should be cleaned according to the instructions.
In addition, if it is necessary to use the respiratory protection-self-priming filter type anti-particle respirator again, it can be hung in a clean, dry and ventilated place or placed in a clean and breathable paper bag. At the same time, medical standard protective masks cannot be cleaned, nor can disinfectants and heating be used for disinfection.
