2. Overview of Occupational Environment Monitoring Services

a. What is occupational environment monitoring in aircraft manufacturing factories?

Occupational environment monitoring (or workplace environmental measurement) in aircraft manufacturing factories is the activity of collecting, assessing, and analyzing measurement indicators of occupational environmental factors at the aircraft factory. The goal is to implement timely measures, minimize environmental impacts on worker health, and prevent occupational diseases. Occupational environment monitoring is a mandatory requirement for aircraft manufacturing factories.

Occupational environment monitoring plays a crucial role in caring for, protecting, and enhancing workers’ health, as workers are the primary resource of enterprises and directly generate profit. Workers who are frequently exposed to risk factors exceeding allowable limits will suffer health effects and develop occupational diseases.
