Local Exhaust Ventilation system monitoring is governed by Occupational Safety & Health Regulations 2000

This Local Exhaust Ventilation assessment is mandatory to be conducted annually, only by a registered Hygiene Technician. However, on monthly basis your organization is allowed to conduct a general self-inspection on the general condition of the system.

In general, the efficiency of the Local Exhaust Ventilation system shall be gauged by the performance of its Duct Velocity, Face Velocity, Capture Velocity, as well as the performance (horse power) of motor and fan (rpm).

It is a requirement by DOSH that the engineering control equipment or systems (LEV) be inspected at least annually besides monthly checking and recording internally. You may refer to the DOSH guideline for more details.
