When should local exhaust ventilation systems regularly be inspected?

Regular inspection of local exhaust ventilation systems during operation is crucial to ensure that they are functioning effectively. This practice helps identify any potential issues, such as blockages, malfunctions, or deterioration of components, which can compromise air quality and worker safety. Frequent checks allow for immediate adjustments or repairs, thus maintaining the intended ventilation effectiveness, and minimizing exposure to hazardous airborne substances.

Regular inspections during operation also facilitate the monitoring of airflow and capture efficiency, thus ensuring that the system consistently protects personnel from harmful contaminants that may be generated during activities like handling chemicals or operating machinery. This ongoing vigilance is essential for maintaining compliance with safety regulations and creating a safe working environment.
