The wearing of breathing masks by coal workers is not an optional form, but a rigid requirement based on the special environment underground. According to statistics, coal miners account for more than 70% of pneumoconiosis patients in China, most of which are related to the long-term lack of effective respiratory protection and inhalation of excessive dust.
The coal dust content in 1 cubic meter of underground air can sometimes exceed 250 milligrams, which is equivalent to half a gram of coal powder entering the lungs with each breath. Over time, it accumulates and gradually erodes the respiratory system, causing symptoms such as coughing, chest tightness, and difficulty breathing, ultimately leading to loss of labor ability and even endangering life. A qualified respiratory half mask can effectively filter dust particles in the air, block respiratory dust from entering the respiratory tract, reduce the risk of pneumoconiosis from the source, and build a solid barrier for the health of coal miners.
Correctly wearing and using the Fandun breathing half mask is necessary to fully utilize its protective effectiveness. Often, the failure of protection is not due to equipment issues, but rather due to improper operation. Before wearing, workers need to clean their hands, carefully inspect the integrity of the half face mask, check whether the filter cotton is damaged or dirty, whether the headband elasticity is good, and whether the exhalation valve is flexible. If there are any problems such as damage or aging, they need to be replaced immediately.
When wearing, it is necessary to fully cover the mouth, nose, and chin with a half face mask, adjust the tightness of the headband to ensure that it fits the head without any pressure, and then use fingertips to press the adjustable nose clip from the nose bridge to both sides to make it closely fit the contour of the nose bridge and prevent dust from seeping into the gap between the nose bridges.
After wearing, it is necessary to conduct an air tightness test: cover the filter cotton with your palm and inhale forcefully. If the mask slightly collapses and there is no airflow leakage, or cover the exhalation valve and exhale without gas overflow, it indicates that the wearing is qualified; If there is air leakage, it is necessary to readjust the headband, nose clip, or replace the mask with a suitable size. During the homework process, it is strictly prohibited to remove half face masks or wear them with exposed nostrils at will, and it is also strictly prohibited to use cotton yarn masks, towels, etc. as substitutes for professional respiratory half face masks to avoid ineffective protection.
Life is paramount, safety is paramount. For coal miners, a small breathing mask protects their health, carries their families, and connects the future. Standardize the wearing, correct use, and timely replacement of the Fandun breathing half mask, implement protection measures, in order to truly stay away from the threat of pneumoconiosis, ensure a safe return from every well, and ensure that every hard work is accompanied by health.
