Walkways shall be properly secured when inclined to a grade of?

• A. 1:4
• B. 1:6
• C. 1:8
• D. 1:10

Answer: (B)

When a walkway is on an incline, its stability becomes a real safety concern because gravity can cause movement of the structure under load or foot traffic. The rule sets a specific slope at which securing the walkway to a fixed support is required, because at that level of incline the risk of shifting, sliding, or tipping becomes significant. Securing the walkway at that grade prevents movement and helps protect workers from falls or the structure failing under use. Softer slopes tend to be stable enough without extra securing, while steeper slopes would also require securing, but the standard identifies that particular incline as the point where securing becomes mandatory.
