Final Answer:
Non-skid shall be applied within approximately 12 inches from coaming and deck edges.
Explanation:
Non-skid materials are often applied to surfaces to enhance traction and prevent slips and falls. The standard practice in many cases is to apply non-skid coatings or materials within a certain distance from coaming and deck edges to ensure safety. The approximate distance specified for applying non-skid is typically around 18 inches from these edges to provide adequate coverage and traction for individuals moving around the area.
