Operating and Maintaining Mechanical Access Covers eLearning
This course will provide training on how to operate and inspect the different access cover types used across the Thames Tideway Tunnel (TTT) scheme, including hinged access covers; drop-in access covers, multi-leaf access covers, and beamed multi-leaf access covers. It will also provide training on how to replace the seals on the access covers.
Description
Key Topic Areas
Training will cover all manufacturers recommended inspection, routine and reactive maintenance requirements, safe isolation and manual operation where available. This will include:
- Potential hazards and risk mitigation associated with the work – discussed and addressed throughout the training below, as it progresses;
- Operation of:
- Hinged access covers;
- Drop-in access covers, including temporary guarding and lifting;
- Multi-leaf access covers, including temporary guarding, lifting and sealing bar removal;
- Multi-leaf beamed covers, including temporary guarding, lifting, sealing bar and beam removal (West Sites only);
- Visual inspection of:
- Hinged access covers;
- Drop-in access covers;
- Multi-leaf access covers;
- Beamed multi-leaf access covers, including identifying safety critical components and potential defects;
- Cover seal replacement (the same for all types);
- Beam seal replacement (multi-leaf covers only).
Competency/Skills Requirements
Before attending the training session, Delegates are expected to complete:
- Safety Fundamentals - Module 2 (Introduction to Hazards);
- Safety Fundamentals - Module 3 (Chamber Access);
- HMI Operator Training Worksite Level;
- Maintenance Fundamentals.
Before attending the training, Delegates are also expected to have:
- Confined space entry training.
Outcomes
On completion of the training, Delegates are expected to:
- Be able to operate all the different cover types;
- Understand how to inspect the general condition of each cover type and identify safety critical defects;
