Across Malaysia, industries are facing increasing pressure to maintain safe working environments while meeting stricter regulatory requirements.
Whether it's:
Airborne contaminants remain one of the most overlooked workplace hazards.
Many companies only take action when:
The reality is:
An effective Local Exhaust Ventilation (LEV) system requires much more than annual inspection.
It requires proper design, installation, commissioning, maintenance, and continuous performance verification.
A Local Exhaust Ventilation (LEV) system is an engineered control designed to capture airborne contaminants at the source before they reach workers' breathing zones.
A properly designed LEV system consists of:
✔ Capture Hood
✔ Ducting Network
✔ Air Cleaning Device (Dust Collector, Scrubber, Filter)
✔ Fan & Motor
✔ Exhaust Stack / Chimney
If any component is poorly designed or maintained, the entire system's effectiveness can be compromised.
This is why leading industries are moving towards a One-Stop LEV Service Model.
Many facilities engage different vendors for:
This often creates challenges:
❌ Design assumptions not communicated to installers
❌ Incorrect fan selection
❌ Poor commissioning data
❌ Difficult troubleshooting when issues arise
When problems occur, responsibility becomes unclear.
A one-stop solution eliminates these gaps.
Every successful LEV project starts with understanding the process.
Before any calculations are made, it is important to evaluate:
Proper assessment ensures the system addresses the actual workplace hazard.
LEV design is not simply selecting a fan.
Engineering considerations include:
A poorly designed LEV system can consume excessive energy while still failing to control exposure effectively.
Even the best design can fail if installation quality is poor.
Critical installation factors include:
Professional installation ensures the system performs as intended.
Before handover, the system should be verified through:
Commissioning confirms that the LEV system performs according to design specifications.
Under the Occupational Safety and Health (Use and Standards of Exposure of Chemicals Hazardous to Health) Regulations 2000 (USECHH 2000), LEV systems used to control chemical exposure must be examined and tested regularly.
Regular inspection helps identify:
Without periodic verification, system performance can gradually decline without obvious signs.
One of the biggest mistakes companies make is waiting until the system fails.
A structured preventive maintenance program helps:
✔ Reduce unexpected breakdowns
✔ Extend equipment lifespan
✔ Improve energy efficiency
✔ Maintain compliance readiness
Preventive maintenance is often significantly cheaper than emergency repairs or premature equipment replacement.
When performance drops, identifying the root cause quickly is essential.
Common issues include:
Effective troubleshooting restores system performance while minimizing production disruption.
Even the best LEV system can be compromised if operators do not understand:
Training creates long-term sustainability and system effectiveness.
