When is it acceptable to stack lumber higher than 20 feet?

• A. When it is secured
• B. When handled mechanically
• C. When it is treated
• D. When it is dry

Answer: (B)

Stacking lumber higher than 20 feet is acceptable when it is handled mechanically. This is because mechanical handling systems, such as forklifts or cranes, can ensure safe stabilization and transportation of lumber at greater heights, minimizing the risk of accidents that can occur when manually handling heavy materials. When lumber is stacked high, the potential for it to become unstable increases, leading to hazards such as toppling or shifting. Mechanical systems contribute to safety by providing controlled movement and support, making it feasible to manage such heights without compromising safety protocols. While securing, treatment, and drying are important aspects of lumber handling, they do not address the specific challenges posed by the height of the stacks. Proper stacking and handling practices should always incorporate mechanical assistance when dealing with lumber at significant heights to mitigate risks effectively.
