This session provides an overview of smoke control measures commonly found in existing buildings, including pressurization systems, smoke exhaust, zoned smoke control, and related fire‑protection features. Attendees will learn how these systems function, how to recognize key components during reviews or inspections, and how to assess whether they align with their intended design objectives.
The session will also highlight common deficiencies encountered in practice—such as improper sequencing, unmaintained equipment, incorrect damper operation, and gaps in documentation—and will present practical strategies for identifying and addressing these issues to improve building safety and compliance.
The following codes and standards will be discussed during the presentation:

2024 Ontario Fire Code Requirements (in force as of January 1, 2026)
2024 Ontario Building Code, Volume 2 – Supplementary Standard SB‑4
NFPA 92 – Standard for Smoke Control Systems
