What is not allowed to be applied to planks used for scaffolding?

• A. Oil Based Paint Or Sealant
• B. Traction Tread
• C. Edges Marked For Identification
• D. Preservative Base Treatment Spray

Answer: (A)

Plank surfaces for scaffolding must stay inspectable and provide good grip. An oil-based paint or sealant is not allowed because it forms a coating that can hide cracks, splits, or rot, making it hard to spot dangerous wear. The coating can also become slippery, especially when wet, increasing the risk of slips and falls. Keeping the plank surface free of such coatings helps ensure any damage is visible and footing remains non-slip. Other options are generally acceptable or used to improve safety (like traction improvements or clear labeling), but coating the wood with oil-based products undermines both visibility of damage and traction.
