According to safety guidelines, how wide must exit doors be at least since 1994?

The correct choice indicates that exit doors must be at least 32 inches wide, a requirement aligned with safety guidelines established to ensure safe and effective egress during emergencies. This width is critical as it allows for the swift movement of people, especially in situations where quick evacuation is necessary, such as during a fire or other hazardous conditions.

The 32-inch width provides adequate space for individuals, including those who may be using mobility aids, to exit without obstruction. Additionally, it helps prevent bottlenecks in crowded situations, where every inch matters for evacuation speed and safety.

This requirement has been consistent in safety codes since 1994, reflecting the increasing awareness of the need for accessibility and rapid exit routes in various building types. In contrast, the other options fall short of this standard set for ensuring safety during emergencies.
