Understanding Local Exhaust Ventilation (LEV)


The primary purpose of Local Exhaust Ventilation (LEV) monitoring is to measure how effectively contaminants are removed from the workplace. This system is designed to reduce employee exposure to airborne contaminants such as dust, mist, fumes, vapour, and gas. By using digital anemometers and manometers, we can accurately measure capture velocity, transport velocity, and face velocity. This ensures that contaminants are properly removed from their source and directed safely to an emission point or to a filtration or scrubbing system.

Objectives of LEV Monitoring


The objectives of Local Exhaust Ventilation (LEV) monitoring, examination, and testing are as follows:


  • To examine, test, and evaluate the performance of LEV systems in controlling airborne contaminants effectively.

  • To recommend remedial actions or improvements based on monitoring results that indicate the need for rectification or system upgrades.

  • To document operational conditions and performance findings obtained during monitoring for future reference and record-keeping.

  • To ensure compliance with the Occupational Safety and Health (Use and Standards of Exposure of Chemicals Hazardous to Health) Regulations 2000.

  • To verify that the LEV monitoring process confirms the system design adheres to approved standards and has been tested by a registered Professional Engineer after construction and installation.
