Amendment BST WaH and WaH/MH V19 October 2025
1. AMENDMENT TO GWO BST V19 – LADDER USE IN WTG
Modules: BST V19 Working at Height Module, BST Working at Height & Manual Handling Combined Module
Subject: Use of reinforced ladder rungs
Effective date: 30 October 2025
2. RATIONALE Due to recent developments, the recommendations on the use of reinforced ladder rungs in WTGs have changed. As a result, instructors shall explain and demonstrate that reinforced ladder rungs are not automatically suitable as anchor points for fall protection or rescue equipment. Such rungs may only be used as anchor points when their sufficient strength is clearly identified, either in the turbine’s safety manual or by markings on the structure indicating where equipment can be attached. In all other cases, fall protection must be secured to the ladder stiles or to certified and structural anchor points. This guidance applies to several elements of the BST V19 WaH Module and the WaH/MH Module. An overview of the changes to the modules is provided below. This amendment ensures alignment with manufacturer requirements and industry guidelines, while clarifying for participants how and when reinforced ladder rungs may be used. It supports safe decision-making by emphasising that reinforced rungs must only be used when clearly identified as suitable.
3. ACTION REQUIRED
• All BST WaH and WaH/MH training providers shall update training to reflect this amendment
• Participants shall be briefed and practice correct attachment methods during training
• This amendment will be fully incorporated into the BST WaH and WaH/MH Module at the next scheduled release in Q1 2026

Amendment BST WaH and WaH/MH V19 October 2025
Explain and demonstrate that reinforced ladder rungs may not be automatically considered to have sufficient strength for attaching fall protection or rescue equipment
Explain that a reinforced ladder rung of sufficient strength may be used as an anchor point when identified by:
a. information provided in the turbine’s safety manual
b. markings on the structure indicating where fall protection or rescue equipment can be attached (see Annex 1)
Demonstrate how to correctly attach fall arrest lanyards and work positioning lanyards:
a. to the ladder stiles and, where clearly identified as suitable, to reinforced ladder rungs. In all other cases, the hooks should be connected around the stiles
b.
to certified and structural anchor points
Facilitate practical exercises for the participants covering the scenarios presented in this element
Provide constructive feedback on the participants’ performance during the practice
Note Alongside manufacturers requirements, internal organisational and site-specific safety guidelines on attaching fall arrest lanyards should always be followed
While adhering to legal regulations and standards, the training provider must continuously ensure that the training material is updated and aligned with industry guidelines from G+, specifically Working at Height in the Offshore Wind Industry
LESSON 14: ELEMENT 14.2 - CORRECT USE OF RESCUE DEVICES & SLINGS
The instructor shall:
Present that pre-use inspection of the evacuation or rescue device may not be required, if it is permitted by the manufacturer’s user manual and the manufacturer criteria
Demonstrate how to perform pre-use inspection of a rescue device product, by covering the following principles:
a.
markings and labels
b.
equipment is within period of formal inspections
c. the rope has no damage, and the end terminations are in good condition
d. the rope runs freely through the device in both directions

Amendment BST WaH and WaH/MH V19 October 2025
e. checking for integrity and the absence of damage, corrosion, saltwater/chemical/lubricant/dirt exposure or contamination
f. checking for the absence of significant wear of the device
g. connectors operate, and lock as intended and cannot disconnect completely
h.
rope securing mechanism works properly
i.
observe product operating temperature range
Demonstrate how to rig the device onto a ladder stile and, where identified as suitable, onto reinforced ladder rungs. If the rungs are not suitable, slings must be connected around the stiles, positioned on one side and centrally on the ladder system, to ensure the moving parts of the device can operate freely
Explain and demonstrate the principles of lifting angle, angle factor and edge protection
Demonstrate how to rig the device in passive setup, and active setup with deflection or deviation applying a friction connector
Stress the generic approach in pre-use inspecting and using a rescue device focusing on similarities and differences in design, functionality, and operation between different products
Explain the potential task placed upon the participant, in their own organisation on course completion, requiring them to familiarise themselves with other safety equipment products
Create a learning activity such as simple quiz, questionnaire or ask the participants open ended questions about:
a. how to perform pre-use inspection of a rescue device product
b. how to rig the device onto a ladder stile and, where identified as suitable, onto reinforced ladder rungs. If the rungs are not suitable, slings must be connected around the stiles, positioned on one side and centrally on the ladder system, to ensure the moving parts of the device can operate freely
c. the principles of lifting angle, angle factor and edge protection
d. how to rig the device in passive setup, and active setup with deflection or deviation applying a friction connector
