The document provides guidelines for officials regarding out of bounds calls and throw-ins: 1) When the ball goes out of bounds, the official should sharply blow their whistle, raise their arm with an open palm, and signal the direction of the new possession. 2) Officials should only call the boundary line that they are responsible for and trust their partners' calls on other lines to avoid double whistles or conflicting calls. 3) Throw-ins must be made within 5 seconds once the ball is given to the inbounding player by the official.
