What is the smallest width allowed for scaffold planking?

The smallest width allowed for scaffold planking is 10 inches. This minimum dimension ensures adequate support and safety for workers and materials on the scaffold. Planking that is too narrow could lead to instability and increase the risk of accidents, as it may not effectively support the weight of the workers or the tools they are using. The specified width helps to provide a stable platform that minimizes the chance of slips or falls, aligning with safety standards in construction and landscaping practices. This consideration is crucial for maintaining a safe working environment at elevated levels.
