Topic Synopsis
This subtopic covers the knowledge and skills required for a secondary role in slinging and signalling loads during tunnelling operations, ensuring safe and efficient load movement through proper planning, communication, and compliance with legislation. It emphasizes the importance of interpreting information, organizing work sequences, selecting resources, and maintaining safety to prevent damage and meet contractual requirements. The practical application involves assisting in rigging, guiding crane operators, and coordinating with the team to move materials or equipment in a confined underground environment.
Key Concepts & Core Principles
- Health and safety legislation: Understand key regulations including the Confined Spaces Regulations 1997, CDM 2015, and the Management of Health and Safety at Work Regulations 1999, and how they apply to tunnelling operations.
- Ground conditions and support systems: Identify different ground types (e.g., rock, clay, water-bearing) and select appropriate temporary support such as steel arches, shotcrete, rock bolts, or lattice girders.
- Excavation methods: Know the difference between hand excavation (e.g., spading, picking) and mechanical excavation (e.g., using a tunnel boring machine or roadheader), including when each is appropriate.
- Monitoring and communication: Use gas detectors, air quality monitors, and communication systems (e.g., radios, signals) to maintain safety in confined spaces and respond to emergencies.
- Risk assessment and method statements: Carry out dynamic risk assessments and follow safe systems of work (SSOW) specific to tunnelling activities, such as excavation, support installation, and mucking out.
Exam Tips & Revision Strategies
- When being observed, clearly verbalise your thought process for each step, including the checks you are performing, to provide evidence of understanding.
- Familiarise yourself with the specific hand signals and radio procedures used on your site, and practice them until they are second nature.
- Always refer to the lift plan and risk assessment before starting any activity; the assessor will look for this disciplined approach.
- Document your inspections and communications meticulously; written records are strong evidence for the portfolio.
- If a problem or near-miss occurs during the assessment, use it as an opportunity to demonstrate your problem-solving and reporting skills, rather than trying to hide it.
Common Misconceptions & Mistakes to Avoid
- Assuming a secondary role requires less understanding of legislation; actually, all team members must be fully aware of LOLER and site rules.
- Using incorrect hand signals or unclear radio communication, leading to confusion and potential accidents.
- Failing to check the load weight and centre of gravity, resulting in an unbalanced lift.
- Neglecting to inspect lifting accessories before each use, which can miss defects like wear or damage.
- Standing in the line of fire or under a suspended load, rather than maintaining a safe position.
Examiner Marking Points
- Clear verbal and non-verbal communication with the crane operator and team members, using standardised hand signals or radio protocols.
- Accurate interpretation of the lifting plan, including weight, centre of gravity, and sling configurations.
- Correct selection and pre-use inspection of slings, shackles, and other lifting accessories, with defects reported and recorded.
- Demonstration of safe positioning during the lift, maintaining exclusion zones and monitoring for encroachments.
- Ensuring the load is securely attached and balanced, with tag lines attached where necessary.
