What are the basic architectural features that provide access to different levels or means of egress from upper levels?

• A. Escalators
• B. Fire escapes
• C. Stairs
• D. Elevators

Answer: (C)

Stairs are the primary vertical connection between floors and the main path people use to get from upper levels to safety. They are designed to stay usable during emergencies, with protected routes, handrails, and landings that keep movement orderly and continuous even when power is out or other systems fail. Escalators and elevators depend on power and machinery and can be unsafe or inoperable during a fire, so they aren’t relied on as the standard means of egress from upper levels. External fire escapes exist in some buildings, but they’re supplemental to the interior stairs and aren’t the universal feature connecting all floors.
