Fire Escape Ventilation

Fire Escape Ventilation by EKG M&E Sdn Bhd

In high-rise safety engineering across Kuala Lumpur and Selangor, fire escape ventilation is the primary defense against the leading cause of fire-related fatalities: smoke inhalation. A fire escape route must remain a "breathable sanctuary" to allow occupants to exit safely and to provide a clear staging area for BOMBA personnel.

EKG M&E Sdn Bhd engineers and installs comprehensive ventilation systems that combine passive design with active mechanical force to meet MS 1472, MS 1780, and UBBL (Uniform Building By-Laws) standards.

The Three Pillars of Escape Ventilation

Effective fire escape ventilation is achieved through a multi-layered approach to air movement.

1. Staircase Pressurization (Active Protection)

For high-rise buildings exceeding 45.75 meters, natural ventilation is often insufficient. We install mechanical pressurization systems that inject fresh air into the stairwell.

• The 50 Pa Shield: The system maintains a positive pressure of 50 Pascals (Pa) inside the stairwell. This physically "pushes back" smoke, preventing it from entering the escape route even if a fire door is opened.

• Velocity Wash: When a door is opened, the system provides an air velocity of 1.0 m/s across the opening to wash away incoming toxic gases.

2. Smoke Lobby & Corridor Extraction (Smoke Spill)

Before smoke reaches the stairwell, it must be managed in the lobbies and corridors.

• Negative Pressure: While the stairwell is pressurized (positive), the fire-affected lobby is put under negative pressure via high-powered extraction fans.

• Fire-Rated Ducting: We utilize 1.2mm heavy-gauge G.I. ducting with a 2-hour fire rating (FRL 120/120/120) to transport hot gases safely out of the building.

3. Natural Ventilation (Passive Safety)

In low-to-mid-rise buildings, we utilize passive vents to clear smoke.

• UBBL Clause 111: We install permanent openings or louvers at every landing. These must be at least 10% of the staircase floor area to allow smoke to buoyant-lift and exit the building naturally.

Critical Operational & Energy Benefits

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

• TNB Energy Efficiency (VFD Synchronization):

  By ensuring all fire-rated ducting is Class C Airtight, we eliminate static pressure loss. This allows your Variable Frequency Drive (VFD) to run motors at lower frequencies (Hz) during mandatory weekly testing, directly reducing your monthly TNB electricity bill.

• EECA 2024 & Building Compliance:

  Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be energy-optimized. Our precision-engineered systems prevent "over-blowing," ensuring energy is used only to maintain the mandatory safety threshold.

• Prevention of "Door-Lock":

  If the pressure is untuned, it can make fire doors impossible to open. EKG calibrates Barometric Relief Dampers to ensure the door-opening force never exceeds the 110 N (Newton) limit.

Ventilation Performance Matrix

Why Choose EKG M&E Sdn Bhd?

• Total 3D BIM Coordination: Fire escape routes are often crowded with sprinklers and electrical conduits. We utilize 3D modeling to route fire-rated ducts with zero "clashes," ensuring optimal placement for uniform air distribution.

• Turnkey BOMBA Submission: We perform the mandatory Pressure Differential Test, Door Opening Force Test, and Anemometer Airflow Traverse required for your Fire Certificate (FC) application.

• Strategic Regional Support: Based in Kuala Lumpur, we provide professional safety audits and installations for Grade-A office towers, luxury condominiums, and hospitals across Malaysia.
