In the 2026 Malaysian regulatory landscape, a BOMBA Approved AHU Plant Room Layout is defined by its ability to act as a localized "Fire Cell." Under the Fire Services Act 1988 (Act 341) and the Uniform Building By-Laws (UBBL) 2026, the plant room must prevent the spread of fire and smoke while ensuring that mechanical assets—specifically those with an AHU Safety Permit—can be safely accessed and audited.
At EKG (Malaysia) SDN BHD, we design layouts that ensure your mechanical infrastructure is Sterile, Silent, and Statutory-Compliant.
To receive BOMBA approval, the plant room must function as a dedicated fire compartment.
Fire Rating: The room must be enclosed by walls and floor slabs with a minimum 2-hour fire-resistance rating.
Passive Fire-Stopping: Every penetration for pipes, cables, and ducts must be sealed with BOMBA-approved intumescent collars or fire mortar to maintain the compartment's integrity.
Fire-Rated Doors: The entrance must be a certified fire-rated door assembly equipped with an automatic door closer and a valid BOMBA "K" Mark label.
A BOMBA-approved layout must balance mechanical performance with emergency access requirements. Under the 2026 MS 1525 and UBBL updates, "overcrowded" plant rooms are a primary cause of audit failure.
| Layout Feature | BOMBA / Statutory Requirement | Engineering Purpose |
| Maintenance Access | Minimum 1000mm frontal clearance | Ensures fire officers and technicians can access the control panel in emergencies. |
| Service Side | Unit Width + 300mm | Allows for coil pull-out without obstruction, ensuring the unit remains auditable. |
| Exit Path | Clear, unobstructed width of 900mm | Provides a safe egress route for personnel during a fire event. |
| Ventilation | Smoke extraction or high-level relief | Prevents heat and smoke buildup within the "Fire Cell." |
A compliant layout must physically integrate the following active fire protection components:
Motorized Fire Dampers: Installed at every duct penetration point through the plant room wall. These must be interlocked with the Automatic Fire Signal AHU Shut-off.
Duct Smoke Detectors: Positioned in the return air plenum to trigger the shutdown of the IE5 EC Fan Walls before smoke is recirculated.
Portable Fire Extinguishers: A minimum of one CO2 extinguisher (for electrical fires) must be mounted near the AHU control panel at a height of 1.2 meters.
As of January 1, 2026, the physical plant room layout must match the building's Digital Birth Certificate.
BIM Verification: We utilize LOD 500 BIM data to verify that all fire-safety hardware—such as dampers and detectors—are installed at the exact coordinates approved by BOMBA.
Audit Readiness: During the mandatory 5-year periodic audit, BOMBA officers use these digital records to verify that no "unauthorized modifications" (such as adding storage racks that block exit paths) have occurred in the plant room.
Technical Integrity: Our layouts are designed by mechanical engineers who specialize in the intersection of thermodynamics and fire-life safety.
BOMBA Submission Management: We manage the entire Form B submission process and coordinate the witness test for the AHU Safety Permit.
GITA Support: Documented compliance with BOMBA safety standards is essential for claiming the 100% Green Investment Tax Allowance.
