Which statement correctly represents the required features of stairs in the context described?

• A. Stairs must be made of wood and have no handrails.
• B. Stairs must be solid and slip resistant, with landings required and handrails on both sides.
• C. Stairs must be solid and slip resistant, with landings so no flight is greater than 12 feet, handrails on both sides, and walls must have a 1 hour rating for three stories or less and 2 hours for four stories or more.
• D. Stairs require only one handrail on the left side.

Answer: (C)

Stairs used as part of a required means of egress must be designed to keep people safe and allow them to evacuate even under fire conditions. The best representation includes key safety features: a solid, slip-resistant construction so treads won’t trip or slide; landings positioned so that no single flight has a vertical rise greater than about 12 feet, which reduces fall risk and provides needed rest points; handrails on both sides to guide and stabilize evacuees; and walls around the stairs that have fire-resistance ratings—typically 1 hour for buildings of three stories or less and 2 hours for buildings with four stories or more—to keep the stair enclosure intact during a fire. This combination ensures the stair system stays usable, protects occupants, and aligns with standard fire-code requirements. The other options fall short because they omit one or more of these essential features (such as lacking balanced handrails, or not providing the required fire-rated walls, or proposing unsafe materials).
