Comprehensive and Detailed Step-by-Step Explanation:
Egress Width Calculation:
According to NFPA 101 (Life Safety Code), Section 7.3.3.1, for non-sprinklered occupancies, the required stair width is 0.3 inches per occupant.
Calculation:
Occupancy capacity = 650 people
Required stair width = 0.3in.×650=195inches0.3 \, \text{in.} \times 650 = 195 \, \text{inches}0.3in.×650=195inches.
Other Options Explained:
Option A (130 in): Too small for 650 occupants.
Option C (217 in): Exceeds the requirement.
Option D (455 in): Far exceeds the requirement.
Summary:
The minimum required total stair width for a non-sprinklered hotel with an occupancy capacity of 650 is 195 inches.
