Ship soldering is one of the core processes in ship manufacturing and maintenance. During the operation, various toxic and harmful pollutants such as lead containing smoke, organic tin compounds, and metal dust are generated. If these pollutants are inhaled by workers, they can cause serious harm to the respiratory system, nervous system, and overall health.
Due to the unique working environment of ships, the layout of cabin spaces is complex, and the ventilation conditions vary significantly. The types and concentrations of pollutants in different working scenarios fluctuate greatly, posing significant challenges to occupational protection work. Among them, the half face mask, as a key protective equipment for workers to resist toxic pollutants, its rational selection and standardized use directly affect the protective effect, and it is also an important defense line to ensure the occupational health and safety of ship soldering workers.
Due to the diverse scenarios of ship soldering operations, there are significant differences in the concentration of pollutants in different compartments and soldering processes. Therefore, the reasonable selection of gas masks is the key to ensuring the effectiveness of protection. When selecting, three core principles should be followed, taking into account both protective performance and job adaptability. For enclosed compartments with high dust concentration, high filtration efficiency filter cotton should be selected to avoid small particles penetrating the filter layer.
Choose the appropriate type based on the homework scenario. For scenarios with good ventilation such as conventional decks, ordinary filtering type gas masks can be used; In enclosed spaces such as cabins and high concentration pollution scenarios, it is recommended to use electric air supply gas masks to reduce respiratory load through active air supply, while maintaining a slightly positive pressure environment inside the mask to prevent welding smoke backflow and adapt to high-intensity work requirements.
No matter how good the protective equipment is, if it is not used properly or maintained properly, it will greatly reduce the protective effect and even lose its protective function. Ship soldering operators must strictly follow the usage regulations, carry out daily use and maintenance of face shields, extend their service life, and ensure stable protective performance.
Occupational health is the foundation of workers and the basis for the safe and stable development of the shipbuilding and maintenance industry. The scientific selection and standardized use of gas masks can effectively build a health defense line for ship soldering workers, prevent occupational health risks, and ensure safe and orderly operation.
