Smoke Control Measures for High-rise Buildings and their Maintenance Requirements

Even though “Smoke Control” is not a defined term in the Fire Code, smoke control features are commonly present in high-rise buildings. Per the requirement of the BC Fire Code, if you have smoke control measures in your building, you are obligated to have these tested to ensure satisfactory operations.

A recent study revealed that the smoke control systems in the majority of high-rise buildings in BC are not tested per the Fire Code. The reason is that there is no stipulated standard on the procedures required for such tests. To make matters worse, most sequence of operations for the originally engineered smoke control features cannot be located. Maintenance contractors are at a loss when it comes to how the smoke control systems are supposed to be tested.

In this presentation, we will attempt to demystify smoke control, by review some of the most common smoke control features in high-rise buildings. We will refer to actual case studies to point out some of the most common issues we found in existing building, explore options on how smoke control features can be evaluated and reviewed. We will then look at means on how a new testing sequence for an existing smoke control system can be re-established and approved.
