6132 Ladder and Scaffold Safety



1.0             Purpose


Jefferson Lab recognizes that working at elevation on ladders and scaffolding is a hazard issue. Employee training, routine inspections, and maintenance requirements are used to reduce the risks. 


Jefferson Lab bases its safety requirements for ladders and scaffolds on the laws, regulations, and references outlined in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.


2.0             Scope


This document addresses the following categories of ladders and scaffolding offered for use at Jefferson Lab:




·         Fixed – Permanently attached to a building or structure.

·         Portable:

o  Step – Self Supporting

o  Extension - a ladder having two or more sections joined by a sliding mechanism that allows the ladder to be extended to the total length. 

o  Mobile Ladder Stand - A fixed height self-supporting ladder consisting of wide flat treads in the form of steps accessing a top step. The assembly may include handrails, and is intended for use by one person.

o  Mobile Ladder Stand Platform - A fixed height self-supporting unit having one or more standing levels, provided with means of access or egress to the platform or platforms. The assembly may include handrails and/or guardrails.

·        Baker Type Scaffold: Scaffold that is easily transportable. Narrow in design. Can be manually moved, if on casters.

·        Tube and Coupler Scaffold: A scaffold system using tubes for posts, bearers, braces, and ties. Special couplers connect the parts. Casters may be used.

·        Tubular Welded Frame Scaffold: A scaffold system using prefabricated welded sections that serve as posts and horizontal bearers. The deck can be built with (stamped) scaffold grade lumber or manufactured deckboards spanning the end-frames.


Jefferson Lab only authorizes the use of ANSI Type I (heavy duty – 250 pounds) ladders (or greater).


All ladders and are to meet the following current ANSI standard as applicable:

·         ANSI A14.2 – Portable Metal Ladders

·         ANSI 14.3 – Fixed Ladders

·         ANSI 14.5 – Portable Reinforced Ladders

·         ANSI 14.7 – Mobile Ladder Stands and Mobile Ladder Stand Platforms


Jefferson Lab does not authorize the use of non-ANSI rated step stools. These restrictions can be waived, on a case by case basis, by the AD-ESH&Q. See ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List for other applicable federal, state, and local requirements.


Jefferson Lab requires that all ladders and scaffolding components used on its behalf be in good working order. Equipment is inspected prior to use, or daily if in continual use. Items found to be in need of repair are taken out of service until the appropriate repairs have been made; or they are removed from site if owned by a subcontractor.

3.0             Responsibilities

NOTE:     Management authority may be delegated at the discretion of the responsible manager.


3.1              Ladder/Scaffold Worker

·         Notify your supervisor if you have any health or physical condition that would affect your safety when working at an elevated height. 

·         Request guidance from your supervisor for ladders/scaffolds with which you are unfamiliar.

·         Complete SAF307 Ladder Safety training before using a ladder.

·         Wear appropriate personal protection equipment (PPE) when assembling, using, and disassembling scaffolding.

·         Obtain authorization for scaffold use from the appointed Competent Person – Scaffold.

·         Abide by hazard mitigation training provided by Competent Person – Scaffold.

·         Inspect, set-up/assemble, use, and store ladders/scaffolds in accordance with the manufacturer’s instructions and Jefferson Lab’s requirements.

·         If repair/maintenance is necessary tag the ladder out of service and contact your ESH&Q Liaison or your Safety Warden.

·         Review and abide by the determination of the Scaffold Inspection Checklist prior to mounting the structure.


3.2              Competent Person - Scaffold

·         Complete the following or equivalent as relevant:

o   SAF303A: Baker Type Scaffolding Safety Training

o   SAF303B: Tube and Coupler Type Scaffold Training

o   SAF303C: Tubular Welded Frame Scaffold Safety Training

·         Ensure Scaffold Worker(s) is appropriately briefed and/or authorized. 

·         Provide scaffold workers with the hazard mitigation training associated with the assigned scaffold.

·         Plan, select, inspect, and maintain scaffold equipment in accordance with manufacture’s specifications and Jefferson Lab requirements.

·         Explain the erection procedure to Scaffold Workers.

·         Monitor scaffold erection.

·         Inspect completed structure before initial use and daily thereafter.

·         Address personnel questions or concerns regarding the construction and/or safety of the scaffolding.


3.3              ESH&Q Liaison/Safety Wardens

·         Inspect fixed and portable ladders in your area of responsibility during routine safety observations /monthly inspections.

·         Facilitate repairs/maintenance as required.


3.4              Supervisor/Subcontracting Officer’s Technical Representative (SOTR)/Sponsor

·         Only purchase and authorize the use of ladders that meet or exceed ANSI Type I (heavy duty – 250 pounds) ladders (or greater).

·         Ensure ladders/scaffolds are inspected, set-up, used, and stored in accordance with manufacturer’s instructions and Jefferson Lab’s requirements. 

·         Only assign ladder/scaffold work to those who are appropriately trained and qualified. 

·         Only authorize the use of equipment that is in good working order.

·         Designate a Competent Person – Scaffold for the duration of the scaffold work. (See ES&H Manual Chapter 6132 Appendix T2 Scaffold for further information). 

·         Coordinate with Occupational Medicine if health conditions or medication prevents a Ladder/Scaffold Worker from using the equipment.


3.4.1        SOTR also:

·         Ensure subcontractor is adequately trained and qualified, minimally to Jefferson Lab requirements (see ES&H Manual Chapter 6132 Appendix T1 Ladders, and T2 Scaffolds) or equivalent. Submit equivalency documentation of Industrial Safety for approval.

4.0             Technical Appendices


4.1              Ladders

There are two basic categories of ladders available for use at Jefferson Lab; fixed and portable. Fixed ladders are permanently attached to buildings or other structures. Portable ladders offer four distinct types: Step (self-supporting), Extension, Mobile-Ladder Stands, and Mobile-Ladder Platforms. ES&H Manual Chapter 6132 Appendix T1 Ladders provides appropriate actions for inspection, set-up, use, and storage of ladders available at Jefferson Lab. 


4.2              Scaffolding

Scaffolding is a temporary, engineered structure used to support people and material during construction or repair work. It is usually a modular system made up of metal tubing although it can be made out of other materials. The most common types of scaffolding used at Jefferson Lab are: Baker type scaffolds, tube and coupler type scaffolds, and tubular welded frame scaffolds. Other types may be used as determined by the Industrial Safety. See ES&H Manual Chapter 6123 Appendix T2 Scaffolds for Jefferson Lab’s requirements for the use of this equipment.


4.3              Use of Ladders on Scaffold or other Elevated Platform

When a scaffold or other elevated work platform height is not adequate for a worker to safely reach a work area, the preferred method for elevating the worker is to add an additional level to the structure. When this is not feasible, Jefferson Lab allows a ladder to be used on the platform but only when specific requirements are met.  ES&H Manual Chapter 6132 Appendix T3 Ladder Use on Scaffold or Elevated Platform provides these requirements.


4.4              Scaffolding Inspection Requirements

Scaffold structures at Jefferson Lab are inspected by a trained and authorized Competent Person – Scaffold prior to first use; daily thereafter; and when there are concerns regarding repair/maintenance/use. ES&H Manual Chapter 6132 Appendix T4 Scaffold Inspection Process provides the process steps for performing initial and subsequent daily inspections; and how the findings from these inspections are communicated to Scaffold Workers and others who may be interested.
