NOTE: When the employer demonstrates that an obstruction cannot be avoided, the distance must be at least 4.5 inches (11 cm). * Verify that each step bolt installed before January 17, 2017 is capable of supporting its maximum intended load, and each step bolt installed on or after January 17, 2017, is capable of supporting at least 4 times its maximum intended load (29 CFR 1910.24(a)(6) - (7)). * Verify that each step bolt is inspected at the start of the workshift and maintained in accordance with 29 CFR 1910.22 (see paragraph 1.4) (29 CFR 1910.24(a)(8)). * Verify that any step bolt that is bent more than 15º from the perpendicular in any direction is removed and replaced with a step bolt that meets requirements before an employee uses it (29 CFR 1910.24(a)(9)).
