2. Overview of occupational environment monitoring service
a. What is occupational environment monitoring at a speaker factory?
Occupational environment monitoring (or workplace environment measurement) at a speaker factory is the activity of collecting, evaluating, and analyzing measurement indicators of occupational environmental factors at the speaker factory, in order to take timely measures to minimize environmental harm to workers’ health and prevent occupational diseases. Occupational environment monitoring is a mandatory requirement for speaker factories.
Occupational environment monitoring plays the most important role in taking care of, protecting, and improving workers’ health because the main resource of enterprises and the direct creators of profit are workers. Workers frequently exposed to risk factors and occupational hazards beyond permitted standards will have their health affected and may develop occupational diseases.
