Confined Spaces Toolbox Talk Template: Stop, Check, Rescue
Proposed URL: /templates/toolbox-talk-confined-spaces Jurisdiction: Great Britain; site-specific confined-space assessment and competent supervision required. Suggested title tag: Confined Spaces Toolbox Talk Template | UK Site Briefing Meta description: A copyable confined spaces toolbox talk with an entry decision, isolation and rescue prompts, worker questions and briefing record. Related hub: /toolbox-talks.
Direct answer
This toolbox talk is a short pre-task briefing for work near or potentially inside a confined space. It is not an entry permit, atmospheric test, risk assessment, rescue plan or training course. The first question is whether the work can be done without entry. If entry is necessary, the team must follow a task-specific safe system with suitable emergency arrangements already in place. HSE's confined-spaces guidance starts with avoiding entry, then a safe system of work, then rescue arrangements before the work begins. HSE confined-space legislation.

Briefing lead's opening: “We are discussing [specific task and space]. No one enters because a previous job used this space safely. We first check whether the work can be done from outside. If entry is unavoidable, the current assessment, isolation, monitoring, communication and rescue arrangements must be in place. If any control is absent or conditions change, stop and withdraw by the approved route.”
Point at the actual space. The team should identify its entry and exit, any ducts or pipework, process connections, stored energy, potential flooding, gas or oxygen-deficient atmosphere, heat and the people who might be affected outside. Do not classify every small room as a confined space; the legal test involves an enclosed or substantially enclosed space with specified serious risks. Equally, a familiar manhole or tank is not safe simply because it has been entered before. HSE introduction.
Five things to discuss with workers
- Can we avoid entry? Consider inspection cameras, remote cleaning, external access or redesign. If the answer is yes, the entry portion of the job should be cancelled and the method updated.
- What can change? A space may become unsafe after a plant restart, an inflow, welding, solvent use or ventilation failure. Controls must match the actual process and neighbouring work. A one-time pre-entry reading may not be enough when conditions can change.
- Who confirms isolation and conditions? The approved safe system should identify equipment, services, test method, competent tester, frequency, alarms and record. A toolbox talk cannot invent thresholds or authorise a worker to test without competence.
- How do we communicate? Entrants and a designated person outside must know the method, check-ins and what loss of contact means. Mobile signal is not an assumed rescue system.
- How will rescue work? HSE requires suitable emergency arrangements before entry. Do not assume emergency services can replace a site rescue plan; unplanned entry by colleagues can create more casualties. Rescue equipment and trained people must fit the actual space and risks. HSE approved code of practice.
Ask these questions aloud
- Show me the entry decision and the current safe system for this space. What is the non-entry option?
- Which isolation would fail if another team started equipment nearby? Who holds the lock/key?
- What is the stop-work signal? Who is the attendant? How will the attendant know everyone is out?
- What happens if someone collapses inside? Who initiates the planned rescue and from where?
- Has the space or task changed since the assessment was approved?
Record answers that reveal a missing control. “We'll sort it later” is a no entry decision. The supervisor should close the gap through the site's formal process before entry, not simply add a note to the attendance sheet.

Example: drain chamber inspection
A drainage crew is asked to inspect a chamber. An inspection camera from the surface may answer the question, so entry is deferred while that option is tested. If entry remains necessary, the supervisor uses the chamber-specific assessment, checks connected flows and isolations, confirms the competent monitoring and communication arrangements, and verifies a realistic rescue plan before authorisation. A general toolbox talk has helped workers recognise the decision but has not granted entry permission.
Common errors
- Treating a signed attendance sheet as a confined-space permit.
- Copying atmosphere figures, RPE or rescue methods from another chamber.
- Letting a colleague attempt an impulsive rescue.
- Assuming the space remains safe after a shift change or process change.
- Leaving the attendant with another duty that prevents effective monitoring.
