How high can stored lumber be stacked if handled manually?

Stored lumber can be stacked up to a height of 16 feet when handled manually in accordance with the guidelines set forth in EM 385-1-1. This limit is established to ensure safety during handling and stacking operations. Stacking lumber higher than this increases the risk of instability and potential accidents, as the lumber may shift or fall if not properly supported or if the stack becomes too tall for safe manual handling.

The guideline emphasizes that workers should maintain safe practices to prevent injuries related to lifting or reaching for high stacks. A maximum height of 16 feet allows for a balance between maximizing storage space and maintaining a safe working environment, reducing the hazards associated with manual handling of heavy or bulky materials.
