6132 Appendix T3: Ladder Use on Scaffolds or Elevated Platforms |
||
|
|||
When a scaffold or other elevated work platform height is not adequate for a worker to safely reach their area of work, the preferred method for elevating the worker is to add an additional level to the structure. If this is not feasible, Industrial Safety allows a ladder to be used on the platform only when specific requirements outlined in Section 4.0 below are met.
The conditions specified in this appendix apply in the instance when a worker must perform jobs while on an elevated platform and is, by any means, elevated above the passive fall protection (e.g., guardrails) system provided. For further information regarding passive fall protection, refer to Chapter 6131, Fall Protection Systems.
This document is an extension of Chapter 6132, Ladder and Scaffold Safety; all relevant content within the chapter applies to the responsibilities and requirements outlined herein.
Note: Management authority may be delegated to a
task-qualified TJNAF employee at the discretion of the responsible manager.

Contact the Industrial Safety Group for
questions regarding ladder and scaffold safety training.
3.1
Ladder
and Scaffold Workers
· complete SAF307 Ladder Safety training before using a ladder on an elevated platform
· obtain authorization and scaffold training from the Competent Person – Scaffold or Supervisor before using a ladder on a scaffold
3.2 Competent Person – Scaffold and Supervisor
· prior to authorizing ladder use on a scaffold or elevated platform, ensure an alternate method (for examples, adding a level or using a man-lift), is not feasible
· ensure platform setup meets fall protection requirements (see 6131, Fall Protection System)
4.0
Requirements for Using a Ladder on Elevated Platforms
Unless stated otherwise, only trained and qualified ladder and scaffold workers may perform the following steps.
4.1
Examine
the Platform
· all structures: ensure passive fall protection system (such as a guardrail) on the working level of the platform meets or exceeds OSHA requirements; and, all sides of the platform are protected. Contact the Competent Person – Scaffold and/or supervisor if the system is inadequate.
· scaffold structure: ensure structure has been planned, selected, erected, and inspected in accordance with the requirements delineated in 6132, Appendix T2: Scaffolds.
4.2 Inspect Ladder Equipment & Ensure
Proper Use
· Inspect the ladder to be used in accordance with the requirements of ES&H Manual Chapter 6132 Appendix T1 Ladders.
· Ensure the “Highest Standing Level” (designated on the ladder’s Duty Rating Sticker) is adequate for the work.
· position ladder at desired location
· measure the distance from the ladder’s base to the nearest platform edge
IF |
THEN |
the ladder’s highest
standing level (D1) plus 6 feet is greater than or equal to
(>) the distance from the ladder base to the nearest
platform edge (D2), |
Competent
Person – Scaffold or Supervisor ·
increase the top rail height of the guard rail to a
distance adequate to the ladder’s highest standing level (D1) OR ·
incorporate
another method of fall protection as found in ES&H Manual Chapter 6131 Fall Protection Systems |
the ladder’s highest standing level (D1)
plus 6 feet is less than (<) the distance from the ladder base to
the nearest platform edge (D2), |
the guardrail
system, as designed, is considered adequate fall protection |

Mitigation and Ladder Use on Scaffolds
In
all cases, when a ladder is used on a scaffold platform, the following,
according to 29 CFR 1926 Subpart L 451(f)(15) is required.
(15) Ladders shall not be used on scaffolds to increase the working level height of employees, except on large area scaffolds where employers have satisfied the following criteria:
(i) When the ladder is placed against a structure which is not a part of the scaffold, the scaffold shall be secured against the sideways thrust exerted by the ladder;
(ii) The platform units shall be secured to the scaffold to prevent their movement;
(iii) The ladder legs shall be on the same platform or other means shall be provided to stabilize the ladder against unequal platform deflection, and
(iv) The ladder legs shall be secured to prevent them from slipping or being pushed off the platform.
