Smoke-Free Escape Routes by EKG M&E Sdn Bhd

In the urban high-rise landscape of Kuala Lumpur and Selangor, fire safety is defined by the integrity of the evacuation path. Smoke-Free Escape Routes are engineered environments—comprising protected corridors, smoke lobbies, and pressurized stairwells—designed to remain tenable even when a fire is active elsewhere in the building.

EKG M&E Sdn Bhd provides the specialized mechanical infrastructure required to keep these routes clear, ensuring full compliance with the Uniform Building By-Laws (UBBL) and BOMBA standards.

The Engineering of a Breathable Sanctuary

A smoke-free escape route relies on a combination of passive compartmentation and active mechanical systems to block the ingress of toxic gases.

1. Staircase Pressurization (The Pressure Shield)

The most critical component of a smoke-free route is the pressurized stairwell. By injecting fresh air into the shaft, we create a pressure differential of 50 Pa.

• Smoke Rejection: When an occupant opens a fire door, the higher air pressure inside the stairwell pushes air out, physically "washing" smoke away from the entrance.

• 1.0 m/s Air Velocity: Under MS 1472, the system must maintain a specific air velocity across open doors to ensure that even in a fully developed fire, smoke cannot "leak" into the escape path.

2. Smoke Lobby & Corridor Extraction

For buildings with deep floor plates, we install smoke spill systems in lobbies and corridors.

• Fire-Rated Extraction: Using 2-hour fire-rated ducts (FRL 120/120/120), these systems suck out heat and toxic fumes, maintaining a clear "breathable zone" at floor level.

• Automatic Activation: These systems are linked to the Fire Alarm Monitoring System (FAMS), activating instantly to ensure the escape route is prepared before the first occupant enters.

Critical Operational & Energy Benefits

As a BOMBA-Compliant M&E Specialist, EKG ensures your safety routes support building efficiency:

• TNB Energy Efficiency (The Airtight Advantage):

  For escape routes to remain smoke-free, the ducting and building envelope must be airtight. By using Class C precision-sealed fire ducts, we minimize static pressure loss. This allows your Variable Frequency Drive (VFD) to run fan motors at lower frequencies (Hz) during mandatory weekly tests, directly resulting in a lower monthly TNB electricity bill.

• EECA 2024 & Building Compliance:

  Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be optimized. Our precision-engineered systems prevent the waste of conditioned air, protecting your Building Energy Index (BEI) and ensuring long-term regulatory compliance.

• The "Golden Hour" for Evacuation:

  A certified smoke-free route provides the "Golden Hour" needed for occupants to exit safely and for BOMBA personnel to enter for rescue and firefighting operations.
