How does ventilation design support OSHA air quality compliance?

Proper ventilation design helps facilities manage airborne contaminant levels in alignment with OSHA permissible exposure limits (PELs). By controlling how contaminants are captured and removed, ventilation systems reduce employee exposure and support compliance efforts. Design also plays a role in documentation and defensibility during audits or inspections. A data-driven approach ensures compliance is based on measurable performance, not assumptions.
