What mask does the welder use?

Because the particle size of welding dust is about 150 nm, the general mask can not effectively protect it. It is suggested that all employees working in welding environment must take good respiratory protection for your health. Choose a dust mask scientifically and choose a good mask with good protective effect, smooth breathing and economical use. Helps prevent lung injury.

Methods of cleaning dust: Now masks must implement GB2626-2006 standard. Dust masks are divided into KN 100, KN95 and KN90. Among them, the protective effect of KN 100 on ultrafine dust can reach nearly100% (more than 99.97%). If the particle size is large, you can choose KN95 grade. The protection effect depends on two aspects. One is the filtration efficiency of cotton filter. The second is the air leakage rate after the mask is matched with the face.

Therefore, masks must be divided into sizes, and the air leakage rate of masks and faces regardless of size varies from person to person.

Methods of cleaning dust: Scientific selection of dust masks certified by GB2626-2006 is helpful to prevent lung injury.

1, select the composite half mask type. Disposable masks have a high air leakage rate and are not suitable for long-term or occupational protection.

2. Select KN 100 grade. Low protection rate in high dust environment will lead to physical injury.

3, choose silicone mask, long service life, soft and comfortable. Long-term wear is not easy to cause allergic reactions. A mask with high hardness is easy to cause facial depression.

4. The size of the mask is extremely important. It is not recommended to buy those so-called universal masks, which are easy to leak.

5. The mask covers the nose and mouth, and covers the nose and mouth and mandible. Suggest using the latter, which is relatively comfortable.

6. It is recommended to choose a mask with smooth breathing. Some masks are designed with double filter cotton and double filter surfaces, which make them breathe smoothly and have a long service life. The welding environment is recommended to be replaced regularly.

It is suggested that occupational protection should be evaluated from the above aspects of quality, grade, comfort and economy, and a good mask should be selected to effectively prevent pneumoconiosis.
