Step-by-step explanation:
A safety net's maximum mesh openings must not be longer than 15 inches on any side.
According to the information provided, the older conventional rule of thumb was 5 side-to-side and 7-8 deep. However, newer research suggests that the maximum mesh openings can be as much as 8 diameters side-to-side and 15 diameters deep.
Therefore, to ensure safety, the maximum length of the mesh openings on any side should not exceed 15 inches.
