In the complex architectural designs of KL and PJ, such as shopping malls, high-rise atria, and industrial warehouses, theoretical airflow calculations must be proven with real-world data. EKG M&E Sdn Bhd specializes in Hot Smoke Testing and Validation, a professional commissioning procedure that uses non-toxic, heated smoke to simulate a real fire. This is the only definitive way to verify that your smoke spill fans, motorized dampers, and pressurization systems perform as intended under emergency conditions.
Standard cold smoke tests only show where air moves under normal conditions. However, in a real fire, smoke is buoyant because it is hot.
Buoyancy Simulation: We use high-output smoke generators equipped with heating elements. This causes the smoke to rise and form a "plume," mimicking the way toxic gases behave in an actual fire.
Plume Entrainment: Hot smoke testing allows us to see how much surrounding air is "pulled into" the smoke layer, helping us validate if the extraction rate (typically 10 ACH) is sufficient to maintain a clear layer for evacuation.
Thermal Stratification: In high atria, we test for "stratification" (where smoke stops rising because it hits a layer of warm air). This ensures your roof-mounted smoke spill fans are positioned correctly to "catch" the smoke before it spreads to lower floors.
As an HVAC & Clean Air Specialist, we conduct a multi-point audit during the smoke test to ensure your building meets BOMBA and UBBL standards:
Clear Layer Height Measurement:
We verify that the smoke extraction system keeps the "Smoke Interface Layer" at least 2.5 meters above the highest occupied floor or balcony. This ensures occupants can breathe clean air while fleeing.
Extraction Efficiency & Plug-Holing:
We monitor the exhaust points to ensure the fans are pulling smoke, not just "clean air" from below the smoke layer (a phenomenon known as plug-holing).
Pressure Shield Verification:
While the hot smoke is active, we check that your Stairwell Pressurization (set at 50 Pa) effectively prevents any smoke from entering the escape routes when fire doors are opened.
Control Logic & Response Time:
We time the system from the moment the smoke detector triggers until the fans hit 100% capacity via the Variable Frequency Drive (VFD) override. BOMBA standards typically require full activation within 60 seconds.
| Stage | Purpose | Benefit |
| New Commissioning | Initial BOMBA Approval. | Guarantees "Form G" compliance. |
| Major Renovations | Change in floor layout/partitioning. | Ensures new walls don't block smoke paths. |
| Annual Safety Audit | Preventive Maintenance. | Proof of readiness for FC renewal. |
| System Troubleshooting | Persistent "Hot Spots" or Smells. | Identifies "Dead Zones" in ventilation. |
Professional Documentation: We provide a comprehensive Validation Report featuring time-stamped photos and video of the smoke movement, along with anemometer and manometer readings. This is a powerful document for insurance audits and BOMBA inspections.
Non-Toxic & Residue-Free: We use high-quality, water-based smoke fluids that are safe for occupants and leave zero residue on luxury retail finishes or sensitive electronic equipment in data centers.
Klang Valley Strategic Support: Based in Kuala Lumpur, we provide on-site hot smoke testing for corporate towers, logistics hubs, and premier shopping malls across the Klang Valley.
