Question

Vertical members at both ends of the horizontal members with intermediate vertical supports that are not more than 3 meters apart at their centers describe:

A) Safety nets
B) Warning lines
C) Guardrails
D) Toe boards

Answer 1

The description provided refers to guardrails, which are safety mechanisms comprising vertical and horizontal members designed to prevent falls from heights. Therefore the correct answer is option (C)

Step-by-step explanation:

The description given refers to C) Guardrails. Guardrails are safety features designed to prevent falls or uncontrolled movement into danger areas, commonly found on platforms, walkways, stairways, and around the perimeter of areas where work is being performed at height. They typically consist of a top rail, mid rail, and a bottom rail (sometimes called a toe board) and are supported by vertical posts. The requirement for intermediate vertical supports to be not more than 3 meters apart at their centers ensures stability and the capacity to withstand force without collapse, providing continuous protection along the guarded edge.
