Updated Standards in Release
Merging of Initial and Refresher Standards
Overview of Changes
Merging of Initial and Refresher Standards
Changes
Refresher and initial training now published in the same standard for: • ART & ART Refresher • BST & BST Refresher • CoHE & CoHE Refresher • EFA & EFA Refresher
Where can I find the refresher training content? •
Refer to the table of contents and the overview for the exact locations of refresher training within the standard.
Merging of Initial and Refresher Standards
Impact Each ‘Module’ now includes initial training & refresher training under different sections No impact on approvals or course codes No change to audit requirements
Benefits
Improved accessibility to find in one location Reduced documentation
: Training content is easier
: Fewer overall Standard
documents to manage Maintains modular approach : Preserves the structured, module -based training framework Updated terminology : Clearer distinction between modules and training types throughout the standard
Basic Safety Training (BST) V20
Overview of Changes
Basic Safety Training (BST) V20
Changes
Working at Height Update: •
Implemented updates from Amendment to Ladder Use in Wind Turbine Generators that clarify how and when reinforced ladder rungs may be used • Terminology aligned with GWO ART when referencing fall arrest lanyards and work positioning lanyards • Updates to evacuation and rescue exercises Sea Survival: Walk to Work Update • Addition of new Lesson 8 in Sea Survival Awareness of Motion - Compensated Gangways (Walk -to-Work) Refresher Training Updates • All five modules now have a dedicated refresher training that includes Skill Stations and Scenario -Based Training Removal of Working at Height & Manual Handling Combined Module • Based on manual handling continuing to have high incident rates and analysis of learning objectives, the combined module was removed.
Basic Safety Training (BST) V20
Impact
Updated WAH:
Updated ladder and anchor -point requirements, aligned terminology with
GWO ART, and rescue exercises have been updated W2W: New 30 -minute lesson Refreshers: Refresher training delivered separately from the initial. Refresher delivery includes Skill Stations followed by Scenarios
Benefits WAH: Increased alignment with industry best practices and training that better reflects on
-site
realities W2W: Closes a behavioural and safety training gap related to motion -compensated gangway systems used in offshore Walk -to-Work transfers Refreshers: Improved quality of training for refresher participants (increased practical focus) Refreshers: Reduced refresher training timings
Advanced Rescue Training (ART) V6
Overview of Changes
Advanced Rescue Training (ART) V6
Changes
Simplified structure:
Combined ART and standalone Single Rescuer modules removed; four clear modules: ART
-H,
ART-N, ART -HR and ART -NR.
Aligned durations:
Initial modules now ~12 h (≈1½ days) each; refreshers 7.5 h (1 day) each, giving a 3
-day initial + 2 -
day refresher package.
Single Rescuer embedded: separate SART courses.
≥90 min single -rescuer application lesson in each module (initial + refresher) instead of
WAH / MH decoupled:
ART no longer recertifies BST Working at Heights or Manual Handling; focus is on advanced
rescue only.
Technical clean -up: All tensioned line / zip -line / tramway examples removed; horizontal movement now taught as cross hauling / controlled horizontal transfer within IFUs.
Patient handling clarified:
Strengthened guidance on cervical collars and transfer boards (airway support only;
boards not used as vertical lifting devices).
Language & layout refreshed: current GWO standard template.
Wording, lesson titles, objectives and timetables aligned across modules and with
Advanced Rescue Training (ART) V6
Impact
Training Providers:
Less complexity, clearer expectations, easier local
programme design and equipment risk assessment.
Certification Bodies / Auditors: areas. Owners / Operators / OEMs:
Sharper audit focus (durations, SR scenarios, equipment compliance) and fewer grey
Better alignment with OEM instructions, stronger assurance on advanced & single rescuer
rescue capability, and reduced exposure from non -compliant techniques.
Benefits
Simpler portfolio:
Four clear modules (ART -H / ART -N / ART -HR / ART -NR); Single Rescuer and combined ART courses
removed. Predictable scheduling:
3-day initial + 2 -day refresher structure that is easier to plan, price and resource.
Stronger competence assurance:
Single Rescuer is consistently trained and refreshed in all modules with ≥90 min focused
practice. Higher technical safety:
Tensioned lines/zip -lines removed; scenarios now based on manufacturer -approved cross hauling
and controlled horizontal transfer. Clearer patient handling:
Reinforced guidance on cervical collars and transfer boards reduces misuse and regulatory risk. – Aligned wording, lesson titles and timetables make the standard easier to interpret, deliver and
Cleaner documentation
audit.
Enhanced First Aid (EFA) V6
Overview of Changes

Changes
Onshore Limited Access module:
Incorporates changes
from the BST Working at Height updates and the Amendment to Ladder Use in Wind Turbine Generators, effective 30 October 2025 Equipment list and terminology aligned with WAH Update Impact Updated ladder and anchor -point requirements, aligned terminology with WAH
Benefits
Align with BST Working at Height updates
Control of Hazardous Energies ( CoHE ) V5
Overview of Changes
Control of Hazardous Energies ( CoHE ) V5
Changes: CoHE Standard reduced to 2 modules Electrical Safety Initial Training (ES) & Refresher Training (ES -R) Module Pressure Fluids Initial Training (PFS) & Refresher Training (PFS -R) Module Durations reduced for initial training Aligned to NFPA70E and others Basic Safety ( BaSC ) content moved to BTT, new module is BTT Hazardous Energies Basic Safety (HEBS) Basic Safety Refresher ( BaSC -R) removed completely from GWO Standards
Control of Hazardous Energies ( CoHE ) V5
Impact Electrical Safety Initial Training (ES) duration reduced to 8 Pressure Fluids Initial Training (PFS) duration reduced to 5.5 Hazardous Energies Basic Safety (HEBS) duration reduced to 2
