Effective January 17, 2017, OSHA 1910 Subpart D (§1910.23 (e) (2) (i)) allows rolling ladders, also known as mobile ladder stands, with a 60 degree or less climb angle to be used by employers, with no minimum climb angle. This change parallels the regulations of the consensus standard for rolling ladders, ANSI ASC A14.7-2011, Safety Requirements for Mobile Ladder Stands and Mobile Ladder Stand Platforms (“ANSI A14.7”), paragraph 4.3.3

Due to updated OSHA requirements (§1910.23 (b) (11)), employers must make certain that ladder users climbing in either direction are facing the ladder steps at all times. ANSI A14.7, paragraph 6.10, allows users to descend rolling ladders facing away from the steps if the climb angle is 50 degrees or less.

As of January 17, 2017, ladders with a 50 degree or less climb angle remain in line with the design regulations of valid OSHA requirements and ANSI standards. Forward decent faced away from ladder steps when climbing downward is no longer permitted by OSHA 1910 subpart D, but is still permitted by ANSI A14.7.

Upcoming revisions of OSHA 1910 Subpart D – Walking-Working Surfaces (click here), and ANSI A1264.1 Safety Requirements for Workplace Walking/Working Surfaces… (click here), also change the regulations for all guardrail systems, gates included. In order to meet the revised requirements, Tri-Arc’s Self-Closing U-Gate will face changes in instillation. Please ensure that current installations meet these updated requirements.

The revisions to OSHA 1910 Subpart D are effective January 17, 2017. ANSI A1264.1-2017, published by the ANSI Standards Action on January 20, 2017, is expected to be available for purchase by February of 2017.
