A large amount of dust will be generated during polishing operations, and wearing the FangDun half mask correctly is an important measure to protect the respiratory system. To ensure the protective effect of the protective gear, the following precautions should be taken:
Pre wearing inspection
Before each use, the appearance of the mask should be checked to ensure that there are no cracks or deformations on the mask body, and that the exhalation valve plate is intact and responsive. Check if the headband has sufficient elasticity and if there is any breakage or looseness. If any damage is found, it should be replaced immediately and not forced to be used.
Correct wearing method
When wearing, the face mask should be tightly attached to the face, and the headband should be adjusted to be moderately tight, neither too tight to cause compression nor too loose to cause air leakage. Subsequently, a airtightness check will be conducted: seal the air intake with your palm and inhale. If the face mask collapses significantly and there is no air leakage, it indicates that the seal is good when wearing it; You can also seal the exhalation valve to exhale and check if there is any airflow leaking from the edge.
Attention during use
When polishing, if you smell dust or feel a significant increase in respiratory resistance, it may be due to clogged filter cotton or ineffective mask sealing. You should immediately leave the work area for inspection. The inside and outside of the mask should be kept clean to avoid the attachment of pollutants. Avoid severe collisions with the face mask during homework to prevent displacement from causing protective failure.
Post use maintenance
After use, the dust adhering to the inside and outside of the mask should be cleaned in a timely manner, and can be wiped with a damp cloth. Do not use organic solvents for cleaning. The filter cotton needs to be replaced regularly. When dust accumulation, darkening of color, or significant increase in respiratory resistance is found, it should be replaced immediately. The face mask should be stored in a clean, dry, and pollution-free environment, avoiding direct sunlight.
regular replacement
FangDun face mask belongs to personal protective equipment. After long-term use, the rubber or silicone material may age and harden, affecting the tightness. It should be replaced regularly according to the product instructions or frequency of use.
