1. 28

2. 30

3. 32

4. 36

The correct answer is: 32

The minimum width for a means of egress door is established to ensure that individuals can safely and efficiently exit a building in case of an emergency. A width of 32 inches is the standard that promotes accessibility and allows for easy movement, especially for people with disabilities or those who may need additional assistance. This width provides sufficient space for individuals moving at a quick pace or carrying objects, as well as for accommodating mobility devices such as wheelchairs. Wider openings are generally preferred in public spaces to enhance safety during evacuation scenarios, reducing the risk of bottlenecks. While other widths such as 28, 30, and 36 inches may have their own applications or minimum code allowances in different contexts, 32 inches is widely recognized in building codes as the minimum required dimension for egress doors, ensuring compliance with safety standards. Thus, it is crucial for contractors to adhere to this specification when designing and installing egress paths in buildings.
