In the enclosed basements of Kuala Lumpur and Selangor, smoke is the most immediate threat during a vehicle fire. Because smoke is buoyant and moves rapidly, it can fill a large carpark in minutes, dropping visibility to zero and raising temperatures to lethal levels. Carpark Smoke Extraction (often called Smoke Spill) is a high-powered mechanical system designed to remove superheated gases and maintain a tenable environment for evacuation.
EKG M&E Sdn Bhd specializes in the design and installation of these life-safety systems, ensuring full compliance with MS 1780, BOMBA regulations, and the Uniform Building By-Laws (UBBL).
Effective extraction is not just about moving air; it is about controlling the movement of smoke to keep it away from people.
The High-Level Layer: Smoke extraction grilles are primarily located at high levels to capture the rising plume. The goal is to keep the "smoke layer" at least 2.5 meters above the floor, maintaining clear visibility at head height for evacuees.
Negative Pressure Shield: The system creates a negative pressure zone in the fire area. This physically prevents smoke from migrating into "positive pressure" zones like elevator lobbies and escape stairwells.
Our systems are engineered to serve two distinct functions using the same ductwork:
Normal Mode (CO Extraction): The fans run at a lower speed (via VFD) to clear vehicle exhaust based on Carbon Monoxide sensor readings.
Fire Mode (Smoke Spill): Upon a signal from the Fire Alarm Monitoring System (FAMS), the fans instantly ramp up to 100% capacity. These fans must be rated to handle temperatures of 300°C to 400°C for at least 2 hours.
As a specialized M&E contractor, EKG ensures your extraction infrastructure supports building efficiency:
TNB Energy Efficiency (VFD Calibration):
By utilizing Variable Frequency Drives (VFDs), we ensure your high-powered extraction motors don't waste electricity during normal operations. Proper calibration ensures the fans hit their mandatory safety targets at the lowest possible frequency (Hz) during weekly testing, reducing your monthly TNB electricity bill.
EECA 2024 & Safety Compliance:
Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be optimized. Our Class C Airtight ducting ensures that the fan's suction is concentrated at the grilles, not lost through leaky joints in the ceiling.
FRL 120/120/120 Fire-Rated Ductwork:
We utilize 1.2mm heavy-gauge G.I. ducting encased in BOMBA-approved fire-rated boards. This ensures the "airway" survives the intense heat of a vehicle fire, allowing the system to continue extracting smoke throughout the evacuation period.
| Feature | Standard Exhaust System | EKG Carpark Smoke Extraction |
| Material Gauge | 0.5mm – 0.8mm GI | 1.2mm (BOMBA Standard) |
| Temperature Rating | Ambient | High-Temp (300°C/2Hrs) |

Total 3D BIM Coordination: Smoke-spill ducts are often the largest conduits in the basement. We utilize 3D modeling to route these heavy ducts with zero "clashes" against sprinklers or structural beams, preserving maximum vehicle headroom.
Turnkey BOMBA Submission: We manage the full process, from technical drawings to performing the mandatory Hot Smoke Tests and Anemometer Airflow Traverse required for your annual Fire Certificate (FC) renewal.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional safety audits and technical proposals for shopping malls, office towers, and luxury residential basements.
