Local Exhaust Ventilation (LEV) Monitoring Objectives and Overview
The primary purpose of Local Exhaust Ventilation (LEV) monitoring is to measure the efficiency of contaminant removal within an exhaust and engineering control system that is specifically designed to reduce employee exposure to airborne contaminants such as dust, mist, fumes, vapour and gas in the workplace. Through Local Exhaust Ventilation (LEV) monitoring, the use of digital anemometers and manometers enables accurate measurement of capture velocity, transport velocity and face velocity to ensure contaminants are properly removed from the source and directed safely to an emission point or to a filtration or scrubbing system.
The objectives of Local Exhaust Ventilation (LEV) monitoring, examination, and testing are as follows:
To examine, test and evaluate the performance of Local Exhaust Ventilation (LEV) monitoring systems in controlling airborne contaminants effectively.
To recommend, where necessary, remedial actions or improvements based on the results of Local Exhaust Ventilation (LEV) monitoring that indicate the need for rectification or system upgrade.
To document the operational conditions and performance findings obtained during Local Exhaust Ventilation (LEV) monitoring for future reference, assessment and record-keeping purposes.
To ensure that all activities related to Local Exhaust Ventilation (LEV) monitoring comply with the Occupational Safety and Health (Use and Standards of Exposure of Chemicals Hazardous to Health) Regulations 2000.
To verify that the Local Exhaust Ventilation (LEV) monitoring process confirms the system design adheres to approved standards and has been tested by a registered Professional Engineer after construction and installation.
In compliance with the Occupational Safety and Health (Use and Standards of Exposure of Chemicals Hazardous to Health) Regulations 2000, employers are required to engage a Hygiene Technician II, registered with the Department of Occupational Safety and Health (DOSH) to carry out Local Exhaust Ventilation (LEV) monitoring.
