Sick Building Syndrome (SBS) or other allergy illness found among officer’s works and resident depended on the internal and external activities. These arisen issues are needed to manage the joined environment as emerging policy that shall both promote health and enhance the personnel’s capability in their working areas without any negative effects.

To promote a healthier environment, Central Lab Thai establishes a technicians and engineers that will determine indoor air/environment quality (IA/EQ) with state of the art equipment as well as suggestions that shall prevent all indoor air related illness sources.
