Should planks of different thicknesses be used to deck out a working platform?

Using planks of different thicknesses for decking a working platform is discouraged primarily to maintain safety and continuity in the working environment. When varying thicknesses of planks are used, it can create uneven surfaces that pose tripping hazards for workers. A uniform deck enhances safety by providing a stable and consistent walking surface, reducing the risk of slips, trips, and falls, which are common accidents on construction sites.

The consistency in the thickness of planks not only aids in worker safety but also allows for predictable load distribution across the platform. This means that the weight applied on the deck can be evenly distributed, minimizing structural weaknesses or failures that could occur if some areas are weaker due to varying plank dimensions.
