Purpose and outcome (what “good” looks like)

This record is your proof that the asbestos register (and any asbestos survey info) was checked and clearly briefed to everyone who could disturb the building fabric (drill, cut, chase, lift tiles, open voids, expose services).

A well-completed record shows:

✅ You used the current register/survey and the right areas/pages.
✅ The team understands where the asbestos risks are (and where things are unknown).
✅ Clear “no drill / no disturb” rules and controls were agreed for the phase.
✅ Everyone knows the stop work and escalation steps.
✅ Names/signatures are captured and filed in the CPP / site file as evidence of active control (CDM 2015).

Who uses it (roles and responsibilities)

Role	What they do
Supervisor / Working foreman (briefing leader)	Leads the check of the register/survey, delivers the briefing, agrees controls, ensures sign-off, and stops work if anything changes.
Operatives (anyone who could disturb fabric)	Attend briefing, ask questions, follow rules/controls, sign the record, stop and report if anything looks different or becomes damaged.
Site Manager / Principal Contractor (if applicable)	Provides the asbestos information, confirms site rules/permits, checks briefings are being done, and supports escalation and controls.
Asbestos competent person / H&S lead (if you have one)	Supports decisions on unknowns, sampling/survey needs, permits, and what to do after a suspected disturbance.
Administrator (optional)	Files completed records, keeps versions tidy, and makes them easy to find during audits/inspections.

When to use it (trigger points and frequency)

At induction for anyone new to site who may disturb fabric.
Before each work phase where you might open up ceilings, walls, floors, risers, ducts, voids, service routes, boxing, or fix into the structure.
Before intrusive tasks: drilling, coring, chasing, breaking out, lifting floor tiles/boards, removing panels, opening voids.
When the plan changes: new area, new route, different method, change of drawings, or any “unknown” becomes relevant.
After any suspected asbestos issue (even a near miss): re-brief before restarting.

Practical rule: if you’re about to make dust or break the seal of the building (tiles/boards/voids), do a briefing record for that phase.

Before you start (what you must have to hand)

Asbestos register for the building (latest version).
Asbestos survey information if available (management / refurbishment / demolition), including any drawings and sample results.
Plans/drawings for the work area and service routes (even simple mark-ups are fine).
Any previous intrusive works records, permits, opening-up photos, or “area cleared” notes (if they exist).
A list of areas you will access in this phase (rooms, levels, plots, risers, ceiling voids).
Names of attendees and a quick check that their Asbestos Awareness training is in date (you don’t need to copy certificates into this sheet, but you should be able to show evidence if asked).
Escalation contacts (supervisor/manager/competent person) and where the site emergency procedure is kept.

Important: If the register/survey does not cover the exact area/void you need to open up, treat it as suspect and plan controls (or arrange sampling/survey) before disturbing.

How to complete it (step by step on site)

Step 1 — Fill in the job and briefing details (2–3 minutes)

Write the project/site, client, and PC (if there is one).
Record the date/time, who led the briefing, and which phase/task you’re about to do.
Be specific about the areas (e.g., “Level 2 corridor ceiling void”, “Plot 14 bathroom walls”, “Riser A”).

Step 2 — Do the “quick check before you start” (prove you actually checked)

Tick items only when done.
Confirm you have the current version (note the date/revision when you get to the “What information was reviewed” section).
Identify any gaps (no access / not inspected / ceiling void not surveyed) and plan how you’ll manage them.
Confirm everyone being briefed is included—especially anyone likely to drill, fix, core, chase, or open up.

Step 3 — Record what documents were reviewed (make it audit-proof)

For each document, enter the date/revision.
In notes, write the pages/areas used (e.g., “Register pages 12–15; Level 1 plant room; riser drawings”).
If something was not available, mark it and record what you did instead (e.g., “Survey not available—PC to provide; treated ceiling void as suspect; no access until confirmed”).

Step 4 — Capture location-specific risks (this is the most important part)

List each work area and note any known or suspected ACMs (what and where).
Write the rule for that area: avoid / isolate / permit (or “no access”).
Write the agreed control in plain terms (e.g., “use existing holes only”, “surface mount containment”, “permit required before any drilling”, “barrier and supervisor check”).
Use the “unknowns” section for any voids/risers/walls that are not confirmed. State what you will do before disturbing (e.g., “arrange sampling”, “request refurbishment survey”, “open-up only under permit after confirmation”).

Step 5 — Brief the site rules and controls (keep it simple and direct)

Read out the “no drill / no disturb” rules and make sure the team understands what counts as disturbing.
Tick the controls you are using on this phase (avoidance, permit, mark-ups, supervision, barriers, pre-start check, sampling, licensed contractor).
If you tick “permit to work”, make sure the permit exists and note the reference in your site paperwork (and in the change/re-brief section if it’s introduced later).

Step 6 — Walk through “stop work & escalation” (everyone must be able to repeat it)

Confirm the team knows: stop, keep people away, isolate, report, don’t clean up, don’t restart until confirmed safe.
Fill in the escalation contacts clearly (names and phone numbers).
Make sure the “site emergency procedure reference” is a real place (e.g., “site office folder”, “QR on noticeboard” if used by the PC, “CPP section X”).

Step 7 — Attendee sign-off (names that matter)

Get signatures from everyone who could disturb fabric—including supervisors, improvers, labourers assisting, and any subcontractors working in the area.
Record whether asbestos awareness is in date and the expiry/reference (keep it simple).
If someone is not in date, they must not do or supervise intrusive work. Rearrange work or update training first, then re-brief.

Step 8 — Re-brief/change record (use it properly, not as an afterthought)

Use it when new areas are accessed, the method changes, drawings change, or an unknown becomes relevant.
Write what changed, what you checked (register/survey pages), and the new controls/permit reference.
If the change is significant (new floor, new riser, new ceiling void), treat it like a mini re-brief and get signatures again if needed.

Step 9 — Briefing leader confirmation

Sign and date once the briefing is complete and you’re satisfied it was understood.
If there are language/literacy issues, record how you ensured understanding (e.g., verbal briefing, photos/mark-ups, translation by supervisor) in your site notes.

Review and approval (what checks should happen)

This record usually does not need “management approval” in a small company, but it does need a real check.

Briefing leader check: documents listed, areas match the job, unknowns captured, controls make sense, contacts completed, signatures obtained.
Site Manager / PC check (where applicable): confirms you used the correct register/survey and that any permit-to-work or restrictions align with site rules.
Escalation point: if there is any doubt about coverage, condition, or unexpected materials, escalate to the PC/asbestos competent person before work continues.

Recordkeeping (storage, retention, and audit readiness)

File completed sheets in the CPP / site file (paper folder on site and/or scanned copy).
Keep them with: asbestos register/survey copy, permits, marked-up drawings/photos, and any sampling results or emails confirming controls.
Use clear naming if digital (example): Site_AsbestosBriefing_2026-03-05_Phase2_Level1Riser.pdf.
Retention: keep for the life of the project and then in your job archive in line with your company system/contract requirements (longer is usually better for exposure-risk evidence).
Make it easy to produce during inspections: one folder/tab for “Asbestos info & briefings”.

How often it should be reviewed/updated

Every new intrusive phase (don’t rely on a briefing from weeks ago if the work area has changed).
Immediately when accessing a new area/void/riser or changing the method.
After any incident/near miss involving suspect materials, damage, or dust release.
When new information arrives (updated register, survey addendum, sampling results, PC instruction).

Common mistakes (and how to avoid them)

Mistake: “We’ve got a register somewhere” but no date/revision recorded.
Fix: Always write the register/survey date/revision and the pages/areas used.
Mistake: Briefing is too generic (“asbestos may be present”).
Fix: Fill the location-specific table with real rooms/levels/voids and clear rules per area.
Mistake: Unknown areas ignored (ceiling voids, risers, behind boxing).
Fix: Use the “unknowns” section and set a clear action: no access until confirmed, sampling/survey, permit control.
Mistake: Only the main trade signs; labourers/assistants and other trades don’t.
Fix: Anyone who could drill/cut/open-up in the phase must be briefed and sign.
Mistake: Controls ticked but not actually in place (e.g., permit mentioned but not issued).
Fix: Don’t tick it unless it’s real and ready. Reference permit numbers in your phase paperwork.
Mistake: People restart after “a small knock” without checking.
Fix: Follow the stop-work steps every time. No restart until confirmed safe and controls updated.
Mistake: Missing evidence when audited (sheet exists but can’t find survey/register).
Fix: File the briefing record together with the asbestos info, mark-ups, permits, and any results.

Worked scenario (what “good” looks like in real life)

Job: Small office refurb. Your team is installing new data runs and needs to lift ceiling tiles and drill fixings for containment.

The supervisor gets the asbestos register and sees it lists ACM ceiling tiles in one corridor and “no access” to a riser.
On the record, they write: “Phase: ceiling access & containment fixings. Areas: GF office, corridor, riser A (outside only).”
They fill the location-risk table:
- Corridor ceiling: ACM noted → rule: no access; control: re-route cables, no tile lifting.
- GF office ceiling: not listed but survey says “limited” → rule: treat as suspect; control: no lifting until PC confirms coverage or sampling arranged.
- Riser A: “no access” → rule: no entry; control: isolate and request survey/permit plan.
They brief “no drill/no disturb”, confirm stop-work steps, and fill escalation contacts.
Everyone who might lift tiles or drill signs the sheet. The supervisor signs as briefing leader.
Two days later the PC provides an updated note confirming GF office void is clear for access under a permit. The supervisor uses the re-brief/change section to record what changed, what was checked, and the new permit reference before work starts.
