WHAT IS LOCAL EXHAUST VENTILATION (LEV) INSPECTION

A Local Exhaust Ventilation (LEV) inspection evaluates the performance of ventilation systems that control airborne contaminants such as dust, fumes, vapors, and gases. The process includes LEV testing, which measures system performance to ensure effective contaminant capture and airflow control. 

In Malaysia, LEV inspection is part of good occupational hygiene practice recommended under the Department of Occupational Safety and Health (DOSH) guidelines and the USECHH Regulations 2000, which require employers to maintain their engineering control systems in proper working condition to minimize exposure to hazardous chemicals.

THE ROLE OF LEV INSPECTION IN MAINTAINING WORKPLACE SAFETY

Poorly maintained LEV systems can lead to ineffective containment of harmful substances, thereby increasing the risk of respiratory issues and long-term health effects for workers. Conducting LEV inspections regularly is essential to maintain workplace safety.

Key roles of LEV inspection include:

• Verify that extraction systems effectively capture and remove hazardous contaminants at the source.
• Measure airflow and system performance through LEV testing to ensure optimal ventilation efficiency.
• Identify wear, blockages, or damage that may reduce extraction effectiveness.
• Provide detailed reports and recommendations for maintenance or corrective action.
• Support compliance with DOSH and international occupational health standards.
