Why these tests matter here
Noise-induced hearing loss builds slowly in yards, compressor houses and container terminals — workers often notice only when family complain about the TV volume. Periodic audiometry is how surveillance catches change early.
Spirometry supports monitoring where dust, fumes or solvents affect the lungs. It is not a casual “blow test” souvenir; technique and interpretation matter.
Results sit inside a wider OHD review: exposure history, symptoms, and whether the worker is fit to continue with or without controls.
