Smoke Extraction Ducting by EKG M&E Sdn Bhd

In the dense urban corridors of Kuala Lumpur and Selangor, the primary threat to life during a building fire is not the flames, but the accumulation of toxic, superheated smoke. Smoke Extraction Ducting (also known as Smoke Spill Ducting) is a specialized mechanical network designed to remove these gases, maintain visibility, and keep temperatures at a level that allows for safe evacuation. EKG M&E Sdn Bhd provides high-performance installations that strictly adhere to BOMBA requirements, MS 1780, and the Uniform Building By-Laws (UBBL).

The Engineering of a Breathable Environment

Standard ventilation ducts fail quickly in a fire. Smoke extraction systems must be "Integrity-Tested" to remain operational while transporting gases at temperatures exceeding 250°C to 400°C.

1. Statutory Compliance (MS 1780 & UBBL)

Under Malaysian law, any non-fire compartmented occupancy exceeding 1,000 square meters above ground, or any basement compartment regardless of size, must be provided with a powered smoke spill system.

• Fire Resistance Level (FRL): Our systems are certified for 120/120/120 (2 hours). This covers Stability (no collapse), Integrity (no smoke leaks), and Insulation (no heat transfer to nearby materials).

• High-Temperature Fans: We install high-static Axial Fans equipped with Class H motors, certified to run at 250°C for 120 minutes.

2. Specialized Construction Methods

• Sheet Metal with Fire-Rated Coating: Conventionally, we use heavy-gauge G.I. ducting (typically 1.2 mm thick for fire compartments) coated with a certified 2-hour fire-rated paint.

• Pre-Fabricated Board Systems: In high-risk areas, we utilize self-supporting calcium silicate or vermiculite board ducts that offer inherent insulation and zero-clearance to walls.

• Zero-Fire-Damper Logic: Unlike standard HVAC, fire dampers must not be installed in smoke extraction ducts, as they would block the extraction of smoke during an emergency.

Critical Operational & Safety Benefits

As a BOMBA-Compliant M&E Specialist, EKG ensures your smoke control infrastructure supports building efficiency:

• TNB Energy Efficiency (Dual-Purpose Logic): Many smoke spill systems serve as daily general ventilation (e.g., removing CO from car parks). By ensuring the system is Class C Airtight, we eliminate air leakage. This allows your Variable Frequency Drive (VFD) to maintain required airflows at lower frequencies (Hz) during normal hours, directly resulting in a lower monthly TNB electricity bill.

• EECA 2024 & Building Compliance: Under the Energy Efficiency and Conservation Act (EECA) 2024, efficient mechanical transport is a core requirement. Our precision-sealed fire ducts prevent the waste of conditioned air, helping lower your Building Energy Index (BEI).

• BOMBA Verification (The 6-Minute Rule): A properly engineered SES ensures that once triggered, the smoke layer is kept high enough that BOMBA personnel can see the "EXIT" signs in lobbies and staircases within 6 minutes of arrival.
