Case Study: Network Rail
Case Study Summary
Principal Contractor: Network Rail
Support Services Provider: Severn Access & Rescue Services
Project Location: Overbridge, Junction 40 M6, Penrith, CA11 9BD
Date of Works: 19–22 May 2025
Executive Summary
In May 2025, Severn Access & Rescue Services were commissioned by a client on behalf of Network Rail, to provide confined space services and specialist rope access services for the installation of acoustic monitoring equipment on a railway bridge over the M6 motorway at Penrith.
The project demanded high levels of technical competence due to the elevated and enclosed nature of the site, which required full compliance with UK health and safety legislation for confined spaces and working at height.
Project Scope
The primary objective was the installation of acoustic monitoring equipment within the internal cells of the bridge structure. These areas were classified as Complex Confined Spaces (NCX), due to their restricted entry and exit points, environmental hazards, and the potential need for rapid emergency response.
Severn Access & Rescue Services’ responsibilities included:
- Confined space entry supervision and control
- Provision of a standby rope rescue team
- Implementation of a site-specific emergency rescue plan
- Risk assessments and method statements (RAMS)
- Traffic and public interface management
- On-site rehearsals of rescue scenarios to validate preparedness
Project Challenges
- Confined and Elevated Environment:
The bridge cells presented spatial and access limitations, increasing the complexity of safe entry and egress. - High-Risk Operations:
The job was classified as high-risk due to potential hazards such as oxygen deficiency, falls from height, and heat stress. - Night-Time Operations:
Much of the work was conducted at night, requiring additional lighting, visibility aids, and contingency planning. - Integration of Rescue Systems:
Rescue procedures necessitated a combination of horizontal and vertical extraction strategies, requiring tailored equipment and highly trained personnel.
Confined Space Methods Utilised
- Site Setup and Briefings:
All personnel underwent detailed site inductions, pre-task briefings, and rescue plan overviews at a designated Entry Control Point (ECP). - Access and Egress:
Operatives accessed the confined spaces via a Mobile Elevated Work Platform (MEWP), transitioning into the structure under fall arrest systems anchored to Petzl hangers. - Atmospheric Monitoring:
Continuous gas detection was mandated throughout all operations. Each worker was issued with calibrated gas monitors and Emergency Life Support Apparatus (ELSA). - Rescue Planning:
A three-person Entry Control/Confined Space Rescue Team (EC/CSRT) was stationed at the entry point throughout. A twin-line rope rescue system and a Chrysalis rescue stretcher were set up for immediate deployment. - Communication Protocols:
Reliable radio contact was maintained at all times, with emergency protocols in place for scenarios such as gas leaks or fire.
Safety & Regulatory Compliance
All operations were fully compliant with:
- The Confined Space Regulations 1997
- The Work at Height Regulations 2007
- CDM Regulations 2015
- BSEN standards including BSEN 795 for anchor systems and BSEN 137 for respiratory protection
Qualified personnel held certifications such as IRATA L1–3, City & Guilds for high-risk confined space entry, and First Aid (including FREC 3/4 and oxygen therapy).
Project Outcomes
- The project was completed safely, within the scheduled four-day time-frame.
- No incidents or injuries were reported.
- Rescue rehearsals confirmed the viability and readiness of emergency plans.
- Daily safety logs and permit systems ensured full traceability and control over site activities.
Confined Space Services for Network Rail: Conclusion
This project exemplifies best practice in the management of complex access operations within hazardous environments. Through meticulous planning, strict adherence to safety legislation, and the deployment of highly trained confined space rescue personnel, Severn Access & Rescue Services enabled the third party contractor on behalf of Network Rail to achieve their operational goals safely and efficiently. The success of the Penrith deployment reinforces the critical value of integrated access and rescue solutions in high-risk infrastructure maintenance projects
