Most factories believe they are safe… until something goes wrong.
A worker starts coughing.
Dust becomes visible in the air.
A DOE or DOSH officer walks in.
And suddenly, the question arises:
“When was your last LEV assessment?”
For many industries in Malaysia, the answer is either “not recently” — or worse — “never properly done.”
This is where the risk begins.
An Annual LEV (Local Exhaust Ventilation) Assessment is a mandatory performance inspection and testing of your ventilation system to ensure it is still effectively controlling airborne contaminants.
It is not just a routine check.
It is a verification of safety, compliance, and system integrity.
A proper LEV assessment includes:
Under USECHH Regulations 2000 (Regulation 27 & 28):
Engineering control equipment must be examined and tested at least once every 12 months by a competent person.
This includes:
But beyond legal penalties — the real consequence is far more serious.
LEV systems don’t fail overnight.
They fail slowly. Silently.
And while the system looks “operational”…
👉 Your workers may already be breathing contaminated air.
Exposure to:
Can lead to:
And once it happens — it cannot be undone.
If your process generates airborne contaminants, annual LEV assessment is not optional.
Even a small process — like grinding or mixing — can generate hazardous exposure if not properly controlled.
Many companies confuse maintenance with assessment.
They are not the same.
| Maintenance | Assessment |
|---|---|
| Fixing issues | Verifying performance |
| Reactive | Preventive & compliance-driven |
| Equipment-focused | Exposure-focused |
👉 You can maintain a system perfectly —
👉 But still fail compliance if airflow is insufficient.
Only an LEV assessment confirms whether your system is actually protecting workers.
Let’s be real, this is where conversion happens.
Companies often delay assessment to “save cost”.
But the real cost is:
One failed audit can cost more than years of proper maintenance and assessment combined.
At ZABSI, we don’t just inspect — we engineer verification.
✔ Airflow measurement using calibrated instruments
✔ Static pressure profiling across system
✔ Smoke test for airflow visualization
✔ Hood capture effectiveness validation
✔ Dust collector & filter integrity check
✔ Detailed compliance report (audit-ready)
We align with:
You should schedule immediately if:
The most dangerous LEV system is not the one that is broken.
It is the one that appears to be working — but is not performing.
Because by the time you notice the problem…
👉 Your workers may already be exposed
👉 Your compliance may already be breached
Protect your workers.
Protect your operation.
Protect your business.
