In 2026, the installation of Fire-Rated Kitchen Exhaust Risers is one of the most critical life-safety requirements for commercial buildings. Under BOMBA (Jabatan Bomba dan Penyelamat Malaysia) regulations and MS 1472, any kitchen exhaust duct passing through multiple floors or fire compartments must be fire-rated to prevent the spread of fire and toxic grease-smoke. For high-rise assets in Kuala Lumpur and Selangor, a non-compliant riser is a primary reason for a failed annual Fire Certificate (FC) renewal.
At EKG M&E Sdn Bhd, we apply 34 years of mechanical engineering expertise to the specialized fabrication and high-altitude rigging of fire-rated systems. We ensure your exhaust path is a "Fortified Tunnel" that protects both your occupants and your building's 5-Star Energy Intensity Label under the EECA 2024.
A kitchen exhaust duct is uniquely dangerous because it is often coated in flammable grease. If a fire starts on the stove, the duct becomes a "Fuse" that can carry the fire to every floor of the building.
Stability, Integrity, and Insulation: We install risers that meet the "3-Hour" or "4-Hour" fire rating. This means the duct will not collapse (Stability), will not allow flames to leak out (Integrity), and will not radiate enough heat to ignite nearby materials (Insulation).
Expansion Management: Fire-rated risers are heavy and expand significantly under heat. We rig these systems with specialized Fire-Rated Expansion Joints and heavy-duty anchors to ensure the duct doesn't buckle and break the fire seal during an event.
Installing a vertical riser through a building's core requires high-precision rigging and specialized materials:
We utilize specialized ductwork that is factory-coated with fire-resistant intumescent spray or wrapped in high-density mineral wool with an aesthetic outer cladding.
Airtight Integrity: To satisfy the EECA 2024, every joint is sealed to DW143 Class C standards. This ensures that your exhaust fans don't waste energy sucking air through leaks, directly lowering your Building Energy Index (BEI).
Rigging a 10-story riser requires a detailed "Lifting Plan." We use specialized winches and hoisting equipment to position duct sections within the vertical shaft. Every section is secured with Fire-Rated Support Brackets designed to withstand the duct's massive dead weight.
The point where the duct passes through the concrete floor is the most vulnerable. We install Fire-Stop Collars and specialized fire-rated sealants to ensure the floor's fire integrity is perfectly restored after the duct is rigged.
Our installation reports provide the "Physical Truth" required for your Professional Engineer (PE) and BOMBA:
| Requirement | BOMBA / MS 1472 Standard | EKG Certified Performance |
| Fire Rating | 2 to 4 Hours (as per UBBL) | Certified & Labelled |
| Leakage Class | High Pressure (Grease-Tight) | Verified DW143 Class C |
| Clean-Out Access | Every 3 Meters / Each Bend | Fitted & Accessible |
| Rigging Safety | Certified Lifting Plan | Fully Documented |
| EECA Status | Airtight Path | Audit-Ready for 5-Star BEI |
Annual Fire Certificate (FC) Security: BOMBA inspections for kitchens are increasingly rigorous. We provide the material certificates and pressure test logs that prove your riser meets the current legal standard.
Lowering TNB Maximum Demand: By using aerodynamic, airtight fittings in the vertical run, we minimize "Static Pressure." This allows your exhaust fans to run at lower frequencies via VFDs, flattening your energy profile.
Grease Management: Our risers are fitted with fire-rated Access Doors at every level. This allows for the mandatory professional cleaning required to prevent grease-fire buildup, a key requirement for insurance compliance.
34 Years of Engineering Depth: Based in KL, we understand the "Stack Effect" and thermal expansion challenges of high-rise risers. We don't just "install pipes"; we engineer a life-safety barrier.
Turnkey Documentation: You receive a comprehensive digital dossier, including pressure test reports, material fire-certificates, and "As-Rigged" shop drawings.
BIM Coordination: We use 3D modeling to ensure your fire-rated riser is perfectly positioned in the shaft, avoiding clashes with fire sprinklers or electrical busbars.
Is your kitchen's fire-safety path a certified barrier or a hidden liability? Contact EKG M&E Sdn Bhd today for specialized fire-rated kitchen exhaust riser installation and secure the safety and compliance of your building.
