Assessment criteria
Topic Overview
The TQUK Level 3 Award in Working as Top Person in High Risk Confined Spaces (RQF) is a specialised qualification designed for individuals who will supervise and manage confined space entry operations from a top-person position. This role is critical in high-risk environments such as sewers, tanks, silos, and other confined spaces where atmospheric hazards, entrapment, or other dangers exist. The qualification covers the legal responsibilities, risk assessment, emergency procedures, and communication protocols required to ensure the safety of all personnel involved in confined space work. It builds on foundational confined space training, focusing specifically on the top person's duties, including monitoring entrants, maintaining communication, and initiating emergency responses.
In the context of Health & Social Care, this qualification is particularly relevant for professionals working in environments like hospital maintenance, care home utilities, or community health facilities where confined spaces may be present. The top person role is vital for compliance with the Confined Spaces Regulations 1997 and the Health and Safety at Work etc. Act 1974. Students will learn to select and use appropriate equipment, interpret gas detection readings, and implement safe systems of work. Mastery of this qualification demonstrates a high level of competence in managing confined space risks, which is essential for career progression in health and safety roles within the care sector.
This award is part of a broader vocational pathway in health and safety, often taken alongside other confined space qualifications or as a standalone unit for experienced workers. It emphasises practical skills and theoretical knowledge, with assessment typically involving a combination of written exams and practical observations. By the end of the course, students will be able to confidently act as the top person, ensuring that all confined space operations are conducted safely and in line with current legislation and best practices.
Key Concepts
Core ideas you must understand for this topic
- →Top Person Responsibilities: The top person is the primary safety supervisor outside the confined space, responsible for maintaining communication, monitoring entrants, and initiating emergency procedures. They must never enter the space and must remain at the entry point at all times.
- →Risk Assessment and Safe Systems of Work: Before any entry, a thorough risk assessment must be conducted, covering atmospheric hazards (e.g., oxygen deficiency, toxic gases), physical risks (e.g., engulfment, mechanical hazards), and human factors. A safe system of work, including a permit-to-work system, must be implemented.
- →Emergency Procedures and Rescue Plans: The top person must be trained in emergency response, including raising the alarm, initiating rescue without entering the space, and using equipment like winches, tripods, and breathing apparatus. A pre-planned rescue strategy is mandatory.
- →Communication Protocols: Effective communication between the top person and entrants is critical. This includes using two-way radios, hand signals, or line-pull signals, and ensuring that communication is maintained at all times. The top person must be able to interpret and respond to distress signals.
- →Gas Detection and Monitoring: The top person must understand how to use and interpret gas detection equipment, including pre-entry checks and continuous monitoring. They must know the action levels for oxygen, flammable gases, and toxic substances like hydrogen sulphide or carbon monoxide.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for correctly completing and checking the permit-to-work, including signatures and validity periods.
- Evidence of thorough pre-entry brief covering hazards, roles, communication, and emergency procedures.
- Demonstration of continuous monitoring of gas levels and maintaining log as per procedures.
- Clear and timely activation of emergency response, including calling rescue team and providing accurate information.
- Effective handover report detailing duration, works completed, any incidents, and environmental readings.
- Award credit for correctly sequencing pre-entry checks: permit validation, atmosphere testing, equipment inspection, and team briefing.
- Look for evidence of continuous atmospheric monitoring and candidate’s ability to identify dangerous trends.
- Credit demonstration of clear, closed-loop communication when directing team actions or acknowledging status reports.
- Assess the candidate’s ability to prioritize life-saving actions during an emergency, such as raising the alarm and initiating the rescue plan without entering the space.
- Check that emergency equipment checks include expiry dates, functionality, and suitability for the specific confined space hazards.
- Verify accurate and legible completion of entry/exit logs, including times and cumulative exposure if relevant.
Assessment Guidance
Guidance for achieving higher grades
- 💡In practical assessments, verbalise your actions clearly to show assessors your decision-making process.
- 💡Always refer to the permit and relevant procedures in your evidence to demonstrate adherence to protocols.
- 💡For written questions, use the STAR method (Situation, Task, Action, Result) when describing how you dealt with an incident.
- 💡Use a methodical checklist approach in practical assessments to demonstrate thoroughness in pre-entry and monitoring tasks.
- 💡Verbalize your actions during scenario-based assessments, explaining why you are performing each check or decision.
- 💡Familiarize yourself with the specific confined space equipment you will use in the assessment, including gas detectors and communication devices.
- 💡In emergency simulations, prioritize safety: call for help, establish communication, and never enter the space unless you are the designated rescuer with appropriate support.
- 💡Pay close attention to the assessor’s brief on the scenario—details like the type of confined space and known hazards will guide your correct response.
- 💡Focus on the specific duties of the top person as distinct from other confined space roles. Examiners look for clear understanding of the top person's legal responsibilities under the Confined Spaces Regulations 1997, especially the prohibition on entering the space.
- 💡When answering questions on risk assessment, always mention the hierarchy of controls: elimination, substitution, engineering controls, and then PPE. Show that you can apply this to confined space scenarios, such as using ventilation before relying on breathing apparatus.
- 💡Practice describing emergency procedures step-by-step. For example, outline the sequence: raise alarm, assess situation, initiate pre-planned rescue, and coordinate with emergency services. Use specific equipment names (e.g., tripod, winch, fall arrest harness) to demonstrate practical knowledge.
Common Mistakes
Common errors to avoid in your coursework
- Assuming the confined space is safe without verifying atmospheric test results or permit conditions.
- Leaving the entry point unattended or being distracted during the work period.
- Failing to maintain a clear log of personnel entering and exiting, leading to confusion in an emergency.
- Inadequate pre-brief where team members do not fully understand their roles or emergency signals.
- Assuming the atmosphere remains safe after initial testing without continuous monitoring or re-testing after breaks.
- Overlooking the need to check emergency rescue equipment, such as harnesses and retrieval systems, before the shift starts.
- Failing to verify that the entry team has received a clear briefing on emergency procedures and escape routes.
- Not maintaining an up-to-date entry log, leading to inaccurate personnel counts during an evacuation.
- Attempting a rescue without following the established plan, placing themselves and others at risk.
- Incomplete handover, omitting ongoing hazards or the location of personnel inside the confined space.
- Misconception: The top person can leave the entry point briefly if the entrants are safe. Correction: The top person must remain at the entry point at all times during the operation. Leaving, even for a moment, compromises safety and is a breach of regulations.
- Misconception: If gas detection shows safe levels at the start, monitoring is not needed throughout. Correction: Atmospheric conditions can change rapidly due to processes, leaks, or disturbances. Continuous monitoring is essential, and the top person must act on any alarm immediately.
- Misconception: The top person's role is purely administrative and does not require physical fitness. Correction: The top person may need to operate rescue equipment, handle heavy loads, or respond quickly in an emergency. Physical fitness and the ability to remain alert for extended periods are important.
