What is the difference between a person in charge and a confined space entrant?

The person in charge (PIC) supervises the entire confined space operation and is responsible for safety, risk assessment, and emergency planning. They typically remain outside the space. An entrant is a team member who physically enters the confined space to perform work. The PIC must ensure entrants are trained, equipped, and monitored, but they do not enter unless specifically designated and trained as an entrant.

How often should atmospheric monitoring be done in a confined space?

Atmospheric monitoring should be continuous while the space is occupied. Before entry, a pre-entry test is conducted to check oxygen, flammable gases, and toxic substances. During work, gas detectors should be worn by entrants or placed in the space to provide real-time readings. If conditions change (e.g., due to welding or chemical use), monitoring must be adjusted accordingly.

What are the legal requirements for a confined space rescue plan?

Under the Confined Spaces Regulations 1997, the rescue plan must be suitable and sufficient, based on the risk assessment. It should include trained rescue personnel, appropriate equipment (e.g., tripods, winches, breathing apparatus), and clear communication procedures. The plan must be rehearsed regularly, and rescue equipment must be maintained and readily accessible. The PIC must ensure the plan is in place before any entry.

Can I use a standard gas detector for all confined spaces?

No, the gas detector must be suitable for the specific hazards present. For example, if there is a risk of hydrogen sulfide, the detector must be capable of measuring that gas. Multi-gas detectors are common, but they must be calibrated for the expected substances. The PIC should select detectors based on the risk assessment and ensure they are calibrated and bump-tested before use.

What does a safe system of work include for confined spaces?

A safe system of work is a documented procedure that covers all aspects of the confined space operation. It includes: a risk assessment, method statement, permit-to-work (if required), selection of competent personnel, atmospheric monitoring, ventilation, PPE, communication methods, emergency rescue plan, and supervision by the PIC. The system must be reviewed and updated as needed.

DAO Level 3 Award in Working in Confined Spaces (Person in Charge)

DEFENCE-AWARDING-ORGANISATION

vocational

This subtopic equips learners with the essential knowledge and skills required for a Person in Charge (PiC) in confined spaces, covering the legal and safety implications, implementation of safe work procedures, and correct use and maintenance of gas detection equipment. It focuses on the PiC's duty to manage entry, oversee atmospheric monitoring, and respond effectively to emergencies, ensuring all operations comply with regulatory requirements.

Working in Confined Spaces

Topic Overview

The DAO Level 3 Award in Working in Confined Spaces (Person in Charge) is a vocational qualification that prepares you to supervise and manage confined space operations safely. It covers the legal responsibilities, risk assessment, and emergency procedures required when acting as the person in charge (PIC) of a team entering confined spaces. This qualification is essential for roles in industries such as construction, utilities, and engineering, where confined space work is common.

As the PIC, you are accountable for ensuring that all entry, work, and exit activities comply with the Confined Spaces Regulations 1997 and other relevant health and safety legislation. The course teaches you to develop safe systems of work, including permit-to-work systems, atmospheric monitoring, and emergency rescue plans. Mastering these skills not only protects lives but also ensures legal compliance and operational efficiency.

This award fits into the broader Design and Technology curriculum by emphasizing practical risk management and problem-solving in real-world scenarios. It builds on your understanding of engineering principles and safety protocols, making you a competent leader in high-risk environments. By the end of the course, you will be able to confidently plan, supervise, and review confined space operations.

Key Concepts

Core ideas you must understand for this topic

→Confined Space Definition: A space with limited entry/exit, not designed for continuous occupancy, and posing risks such as toxic gases, oxygen deficiency, or engulfment. Examples include tanks, silos, and sewers.
→Person in Charge (PIC) Responsibilities: The PIC must ensure a safe system of work is in place, including risk assessment, selection of equipment, and supervision of the team. They are legally accountable under the Confined Spaces Regulations 1997.
→Risk Assessment: A systematic process to identify hazards (e.g., hazardous substances, flammable atmospheres) and implement control measures. The PIC must review and approve the assessment before work begins.
→Atmospheric Monitoring: Using gas detectors to check oxygen levels (19.5-23.5%), flammable gases (<10% LEL), and toxic substances (e.g., H2S, CO). Continuous monitoring is critical during entry.
→Emergency Procedures: The PIC must establish a rescue plan, including trained rescue personnel, equipment (e.g., tripods, harnesses), and communication methods. Drills should be conducted regularly.

Assessment Guidance

Guidance for achieving higher grades

💡Always refer to relevant legislation such as the Confined Spaces Regulations 1997 and industry guidance.
💡In practical assessments, clearly verbalise your actions and decisions to demonstrate underpinning knowledge.
💡Use correct technical terms for gas properties and detection methods (e.g., LEL, TWA, STEL).
💡Practice equipment calibration procedures until they become second nature to avoid assessable errors.
💡Structure answers around the hierarchy of control: eliminate, isolate, engineer, administer, and PPE.
💡Tip 1: When answering questions on risk assessment, always mention the hierarchy of controls (elimination, substitution, engineering controls, etc.) and give specific examples relevant to confined spaces, such as ventilation or lockout/tagout.
💡Tip 2: For emergency procedures, emphasize the importance of a pre-planned rescue method that does not put others at risk. Mention the need for rescue equipment to be readily available and regularly inspected.
💡Tip 3: Use correct terminology from the Confined Spaces Regulations 1997, such as 'safe system of work' and 'competent person.' Examiners look for precise language that shows you understand legal requirements.

Common Mistakes

Common errors to avoid in your coursework

Confusing confined space regulations with general workplace health and safety requirements.
Failing to test the atmosphere at multiple levels and corners before and during entry.
Neglecting to maintain constant communication with entrants and standby person.
Assuming a space is safe after one acceptable reading, ignoring potential changes due to work activities.
Overlooking the requirement for a site-specific rescue plan and retrieval equipment.
Misconception: 'A confined space is only a small, enclosed area.' Correction: Confined spaces can be large (e.g., a storage tank) but are defined by limited entry/exit and potential hazards, not size.
Misconception: 'Once the atmosphere is tested, it's safe for the whole shift.' Correction: Atmospheric conditions can change due to work activities (e.g., welding, chemical reactions). Continuous monitoring is required.
Misconception: 'The PIC can enter the space if needed.' Correction: The PIC should not enter unless they are also trained and equipped as an entrant. Their primary role is supervision and coordination from outside.
