Stacks of loose bricks that exceed a height of 4 feet should be tapered back every foot. This method is used to create a stable structure that minimizes the risk of the stack toppling over. When bricks are stacked straight up, the center of gravity rises, making the pile more susceptible to falling, especially in windy conditions or if someone bumps into it.

By tapering the stack back, each higher layer of bricks recedes slightly from the layer below, which lowers the center of gravity and enhances the stack's overall stability. This practice is critical in construction to ensure safety and prevent accidents on the job site. Maintaining proper stacking techniques not only complies with safety regulations but also promotes efficient workflow since it reduces the likelihood of having to clear up after toppled bricks or injuries caused by falling materials.
