Which risk is associated with painting the flat surface of cribbing blocks?

• A. It can hide defects and make the surface slippery
• B. It improves grip in wet conditions
• C. It increases weight
• D. It reduces cost

Answer: (A)

Coatings on the flat surfaces of cribbing blocks can mask hidden damage and create slip hazards. These blocks are relied on to provide stable, level support for heavy loads, so the surface must be capable of transmitting load without hiding problems. Painting can conceal cracks, splits, rot, or other defects that would signal the block might fail under load. A painted surface can also become slick, especially if dirt or moisture is present, reducing friction between the block and the load or supporting surface and increasing the chance of movement or slip. For safety, cribbing should present a clean, unmasked surface that allows quick inspection for damage and maintains good grip. The notion that painting improves grip in wet conditions isn’t accurate, and painting adds negligible weight while not offering a real safety benefit in terms of cost.
