Rule 11.2.3:  At all times during timed construction every builder and the superintendent must wear personal protective equipment in the proper manner (e.g. hardhats with peak in front).

SUGGESTION:  Make sure that your team practices with the equipment properly worn.

Rule 11.2.13: A builder must not use the bridge, a portion of the bridge, a temporary pier, or a tool to support the builder's body weight.  For example, lying, standing, sitting or kneeling on those objects is prohibited.  However a builder may lean on a constructed portion if the builder is kneeling on both knees, knelling on the ground on one knee with the other foot on the ground, or standing with the heels and toes of both feet on the ground.

Common Error:  It is sometimes difficult to stay focused on this rule during the heat of construction.
