What is the maximum allowable stack height in a lumber yard?

The correct answer indicating a maximum allowable stack height in a lumber yard is 15 feet because this measurement aligns with safety regulations and practices designed to minimize fire hazards. Lumber, being highly combustible, poses significant risks if stacked too high, as the increased height can diminish airflow, make it more difficult to manage the fire, and increase the likelihood of a fire spreading rapidly if one were to occur.

Maintaining a maximum stack height of 15 feet ensures that there is an adequate margin for safety, allowing for better inspection, quicker access in emergencies, and reducing risks associated with potential collapses of unstable stacks. Higher stacks may compromise safety protocols, increasing the risk of accidents and fire hazards, which is why regulatory standards often dictate lower height limits in storage areas like lumber yards.
