Masks should be familiar to everyone and often used in daily life. The masks used in different working environments are also different. The dust in the working environment is much more special. At this time, workers must wear dust masks. Do you really know how to use and store dust masks correctly? The following editor of disposable masks will give users a brief introduction, hoping to popularize this knowledge.
Choose the right mask. According to the concentration of harmful substances, toxicity, dust particle size, worker's face and head size, and labor intensity, select the corresponding dust mask and filter material model; pay attention to the quality of the mask. First, check whether all parts of the mask are intact, whether the exhalation valve is wrinkled, deformed, too thin, and not airtight (at this time, if the air inlet of the mask is blocked, there will be air leakage), the exhalation valve seat and rubber valve Whether the contact is smooth and complete, and whether the connection between the valve seat and the main body is tight.
The curling, breakage and deformation of the mask body or breathing valve are not suitable for use, so the mask should be replaced or a new one should be used.
Pay attention to wearing a mask correctly. The mask must be worn correctly, covering the nose and mouth. There should be no gaps on both sides of the bridge of the nose. If there are any gaps, you can stick them with tape to avoid side leakage. The mask should be fastened separately and not hung on the ear. It is necessary to prevent the mask from loosening, leaking and squeezing the face and nose. For example, my country's dust masks enjoy a good reputation in terms of safety, service life and comfort.
Keep the mask clean. When you are temporarily not wearing a mask, you should put the mask in a protective bag made of plastic to prevent dust and corrosive gases from contaminating the mask. Don’t hang it on your chest, distinguish the inside and outside of the mask, and don’t let the contents touch other clothes.
Clean and maintain various masks and mask bags frequently, and clean them every day, otherwise harmful gases and dust will accumulate, which will not only not protect the body over time, but may also cause harm to the body!
