In the fire safety architecture of Kuala Lumpur and Selangor, fire escape vents are critical components that manage air movement within evacuation routes. Their primary purpose is to ensure that stairwells and exit paths remain free of toxic smoke, allowing occupants to flee and BOMBA personnel to enter safely.
EKG M&E Sdn Bhd provides specialized venting solutions that strictly adhere to the Uniform Building By-Laws (UBBL) and MS 1472 standards.
For low-to-medium rise buildings, natural vents are the standard method for clearing smoke from fire escapes.
UBBL Clause 111 Compliance: These buildings must have permanent openings to the exterior. Typically, these vents must equal at least 10% of the staircase floor area or 1.0 square meter per floor.
Buoyancy-Driven Flow: Since hot smoke naturally rises, these vents allow it to exit the building at each landing, maintaining a "clear zone" at the walking level for evacuees.
In high-rise buildings where mechanical staircase pressurization is used, vents act as "safety valves."
The 110 N Safety Limit: If a pressurization fan is too powerful, the air pressure can make fire doors impossible to open. We install Barometric Relief Dampers (BRDs) that automatically open when the internal pressure exceeds 50 Pa, ensuring the door-opening force stays below the mandatory 110 N limit.
Fire-Rated Integration: These vents are often connected to 2-hour fire-rated ducting (FRL 120/120/120) to ensure that fire from one floor cannot "jump" into the staircase via the relief path.
As a BOMBA-Compliant M&E Specialist, EKG ensures your venting infrastructure supports long-term building performance:
TNB Energy Efficiency (Leakage Control):
During normal building operations, poorly sealed vents allow expensive conditioned air to leak out. By using Low-Leakage Motorized Vents, we ensure the staircase is hermetically sealed when there is no fire. This reduces the load on your primary AC system, resulting in a lower monthly TNB electricity bill.
EECA 2024 & Building Compliance:
Under the Energy Efficiency and Conservation Act (EECA) 2024, every mechanical opening must be optimized. Our precision-engineered vents prevent energy waste while ensuring life-safety systems are ready for audit.
Acoustic Comfort:
Properly calibrated relief vents eliminate the high-pitched "whistling" sounds often heard in high-rise stairwells caused by air forcing itself through door gaskets in unbalanced systems.
| Feature | Natural Ventilation Vents | EKG Mechanical Relief Vents |
| Building Type | Low-to-Mid Rise | High-Rise / Basements |
| Activation | Always Open / Fusible Link | Automatic (Pressure-Sensing) |
| Pressure Control | Unregulated | Maintains 50 Pa Safety Shield |
| Fire Rating | Standard Weather Louvers | Mandatory 2-Hour Rated |
| BOMBA Requirement | UBBL Compliance | Mandatory for Fire Certificate (FC) |
Total 3D BIM Coordination: Vents must be placed strategically to avoid "smoke re-entry" into other floors. We utilize 3D modeling to coordinate vent placement with the building's facade and other mechanical services.
Turnkey BOMBA Submission: We perform the mandatory Door Opening Force Test and Pressure Differential Test required for your annual Fire Certificate (FC) renewal.
Precision Engineering: Based in Kuala Lumpur, we provide professional safety audits and installations for Grade-A office towers, luxury condominiums, and hospitals across Malaysia.
