Seating Arrangements for Large Assembly Events
According to the International Fire Code (IFC) 2021, Section 1029.14, when more than 500 chairs are used for an assembly event held in a gymnasium (or similar venue), they must be either:
Secured to the floor OR
Fastened together in groups of at least three (3) chairs.
2. Why Groups of 3 is the Correct Answer
This requirement ensures organized seating, preventing chairs from shifting or obstructing aisles during emergencies.
Properly fastened chairs reduce the risk of crowd-related hazards, ensuring safe and efficient evacuation if needed.
3. Verification of Other Options
Option A (spaced at least 6 inches apart) - Incorrect, as the IFC requires chairs to be fastened together or secured when over 500 are used.
Option C (groups of not less than 6) - Incorrect, as the minimum required grouping is 3.
Option D (groups of not less than 10) - Incorrect, as the IFC does not mandate groups of 10.
