What are the monitoring measures for the working environment of pneumoconiosis?

1. technical measures: eliminating or reducing dust hazards with engineering technical measures is the most fundamental measure to prevent pneumoconiosis.

① Transformation of process flow and production equipment is the main way to eliminate dust hazards, such as remote control, computer control, compartment monitoring, etc., to avoid contact with dust.

(2) Wet operation: such as timely or wet grinding of refractory materials, wet drilling in mines, underground transportation and water spraying, high-pressure water injection in coal seams, etc. By adopting the invention, dust flying can be prevented to a great extent, and the environmental dust concentration can be reduced.

③ Sealing, ventilation and dust removal: For places where wet operation is not feasible, sealing, ventilation and dust removal should be adopted. If the closed dust source is combined with local ventilation, dust can be prevented from escaping.

2. Health measures

① Health monitoring of workers exposed to dust: including pre-job physical examination, on-job regular physical examination and off-job physical examination. Workers who have been exposed to dust for a long time are required to follow up after leaving their posts.

② Personal protection and hygiene: Wear dust protective gear, such as dust helmet, dust mask, air supply helmet, air supply mask, etc. Pay attention to personal hygiene, change your work clothes and take a bath frequently.
