New fact sheet provides ladder jack scaffolding requirements

Devices must follow specific OSHA standards

Posted May 6, 2016

OSHA published a new fact sheet related to scaffolds, Ladder Jack Scaffolds. It explains how to prevent injuries from falls when using work platforms supported by ladders.

The fact sheet defines ladder jacks including the side rail (over the rail and rung) and the two or three rung bracket ladder jacks (over the rung). It also provides instruction for setting up and using ladder jack scaffolds.

In the document, the agency listed the OSHA standards that apply to construction operations involving the use of ladder jack scaffolding, including:

  • Ladder Jack Scaffold: A platform resting on brackets attached to ladders [§1926.450(b)];
  • Supported Scaffold: One or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames, or similar rigid support [§1926.450(b)];
  • Ladder Jack Scaffolds: requirements applicable to specific types of scaffolds (29 CFR 1926 Subpart L – Scaffolds), including requirement that all ladders used to support ladder jack scaffolds meet the requirements of Subpart X – Stairways and Ladders) [§1926.452(k)];
  • Non-Mandatory Guidelines: 29 CFR 1926 Subpart L, Appendix A – Scaffold Specifications.

The fact sheet also provides platform, ladder, and fall protection requirements as well as the training employers must provide to workers.
