Occupational Hygiene Measurement and Analysis Services
Our occupational hygiene services encompass the measurement, analysis, and reporting of physical and chemical factors in work environments. The measurement plan is specially prepared according to the enterprise’s activities and exposure sources.
Measurement Planning
Field conditions, processes, and exposure sources are evaluated.
Sampling
Personal or ambient samples are collected using appropriate methods and equipment.
Analysis
Samples are analyzed in the laboratory according to relevant reference methods.
Reporting
Results are technically evaluated and clearly reported.
