The importance of personal respiratory protection cannot be ignored in the rail vehicle industry. In the manufacturing, maintenance, and operation processes of this industry, workers may be exposed to various harmful environments and substances, such as welding fumes, polishing dust, organic gases generated by spray painting, metal splashes, etc. These hazardous factors not only affect the short-term health of employees, but long-term exposure may also lead to chronic respiratory diseases and other serious health problems.

So, how should we practice personal respiratory protection?

1. Comprehensive assessment of the working environment: First of all, it is necessary to conduct a detailed assessment of the environment that may be encountered during the manufacturing and maintenance of rail vehicles to identify the existing occupational hazard factors.

2. Choose the appropriate respiratory protective equipment: According to the evaluation results, choose the appropriate respiratory protective equipment. This may include:
Full cover: For example, JD-910 full cover, with 9000 series filter box and 9295P filter cotton, can provide full face and respiratory protection, suitable for high-risk environment, dust and poison dual protection, to ensure health.
Half mask: such as JD-905/JD-906, suitable for medium risk environments, protecting the mouth and nose.
Dust mask: such as JD-900/JD-901, for dust and particulate protection, choose a dust mask that meets national standards.

3. Use electric air supply long tube respirator: In hypoxic or toxic gas environment, electric air supply long tube respirator can provide clean air and protect staff from harmful gases.

4. Regular maintenance and testing: All respiratory protective equipment should be regularly maintained and tested to ensure that its performance meets safety standards.

5. Training and education: Staff are trained in the use of respiratory protective equipment to ensure that they understand how to properly use the equipment in different environments.

6. Emergency preparedness: Develop emergency plans, including how to quickly evacuate and rescue measures in an emergency.

7. Regulatory compliance: Ensure that respiratory protection programs comply with national and regional safety regulations.

8. Continuous monitoring and improvement: Continuous improvement of respiratory protection programs through continuous monitoring of the working environment and employee health.

9. Development and prospect of individual respiratory protective equipment: With the progress of science and technology, individual respiratory protective equipment is also developing. Researchers are developing respiratory protective materials and technologies with intelligent health monitoring capabilities that can improve the effectiveness of respiratory protective equipment while monitoring workers' respiratory health.

10. Occupational health training: Strengthen occupational health knowledge training, improve the cognition of employees, guide the enterprise team to carry out occupational health risk factor identification and "5S" activities, so as to reduce the occurrence of occupational diseases.

Through the above program, it can provide a safe working environment for workers in the rail vehicle manufacturing industry and protect them from harmful gases and dust.
