How wide must exit doors be at minimum, for buildings constructed before 1994?

1. 36 inches

2. 28 inches

3. 30 inches

4. 32 inches

The correct answer is: 28 inches

For buildings constructed before 1994, the minimum required width for exit doors is 28 inches. This measurement is rooted in safety regulations aimed at ensuring that individuals can evacuate a building quickly and safely in an emergency, such as a fire or other urgent situation. The 28-inch requirement is based on the need for accessibility and an effective flow of people during an evacuation. A wider door can facilitate quicker movement and accommodate various mobility devices if necessary. Standards and codes, such as those from the National Fire Protection Association (NFPA) and the International Building Code (IBC), have evolved over time, and more recent regulations often specify wider exit door requirements to enhance safety further. However, understanding historical codes is essential, particularly in the context of buildings built before 1994, where the 28-inch minimum would apply. By knowing this standard, safety professionals can assess older structures and ensure compliance with the applicable regulations for existing constructions.
