Purpose and outcome (what good looks like)

This guidance note explains how to use the Weekly Site Safety Inspection & Action Tracker as a repeatable walkround that finds real issues, fixes what you can on the spot, and tracks the rest to a clear close-out.

Good completion looks like:

A consistent weekly walkround route (same order each week).
Clear ticks (OK / Action / N/A) with short, specific notes where anything is not OK.
Actions written so someone can do them without guessing (what/where/standard), with an owner and due date.
Dangerous situations stopped and made safe before you move on (and recorded).
Actions followed up mid-week and signed off when closed.
Filed sheets that show planned monitoring under CDM 2015.

Who uses it (roles and responsibilities)

Role	What they do
Supervisor (Inspector)	Leads the walkround, completes the sheet, agrees actions, stops unsafe work if needed, chases close-out.
Worker Rep	Walks with the supervisor, points out “how it’s really being done”, helps agree practical fixes, supports buy-in.
Site Manager / PC Rep (if applicable)	Reviews key findings, supports escalation (plant routes, scaffolding changes, shutdowns), signs if your site rules require it.
Action Owners (trades, foreman, subcontractors)	Complete assigned actions by the due date and provide evidence (photo, tag, receipt, permit, etc.).
Office / Admin (optional)	Files completed sheets, keeps versions in order, helps chase outstanding actions.

When to use it (triggers and frequency)

Frequency: weekly on live sites (pick a fixed day/time if possible).
Also use after:
- a significant change (new phase, new subcontractor, new work at height, new excavation, new lifting plan);
- an incident or near miss (do an extra walkround focusing on that risk);
- major weather impacts (high winds, heavy rain affecting excavations/edge protection).
Project workflow: start once the site is set up and continue through to demobilisation. Use the “carry-over” section to prove you are following up, not just inspecting.

Before you start (inputs and preparation)

Spend 5 minutes getting the basics together so the walkround is quick and useful.

Today’s plan: what tasks are happening, where, and who is doing them.
Key documents on site (as relevant): RAMS/briefing notes, lifting plan, excavation permits/utility scans, scaffold/tower inspection tags, temporary electrics checks/PAT info.
Last week’s sheet: check open actions and bring them with you (so you can close them out or re-plan).
Basic kit: pen, phone/camera for photos, marker spray/tape for quick marking, and the right PPE.
Right people: supervisor + one worker rep. If you know there’s a high-risk activity, invite the relevant trade (e.g., lifting supervisor, groundworks lead).

How to complete it (step-by-step)

Step 1 — Fill in the inspection details (2 minutes)

Project/site, date/time, who inspected, worker rep name/trade, areas walked, approximate headcount.
Be specific on areas walked (e.g., “plot 3 roof edge, rear excavation, compound, loading bay”).

Step 2 — Agree the walkround route (1 minute)

Walk the site in the same order each week. A simple route is: gate/compound → workfaces → plant routes/loading → storage → welfare → emergency routes/exits.

Step 3 — Use the checklist properly (20–45 minutes)

For each line item, tick OK, Action, or N/A.
If you tick Action, write a short note that answers:
- Where? (exact location/level/plot)
- What’s wrong? (what you saw)
- What good looks like? (barrier reinstated, edge protected, leads routed, tags in date, etc.)
Keep notes short. The detail belongs in the actions table.

Stop-and-make-safe rule: if it’s dangerous right now (e.g., missing edge protection, live excavation unprotected, people under a suspended load), stop the activity and make safe before continuing. Record what was stopped and who made it safe.

Step 4 — Convert findings into actions (10 minutes)

Every “Action” tick should result in either:

a fix done immediately (and noted), or
an entry in the Actions Tracker.

Write actions so they can be closed out cleanly:

Action: start with a verb (Install / Repair / Remove / Re-route / Barrier / Label / Inspect).
Owner: a named person or trade lead (not “site”).
Due date: realistic and risk-based (high risk = today/24 hours).
Status: keep it simple (Open/Done) and update it during the week.
Close-out sign-off: name/date once verified on site (not just “they said it’s done”).

Tip: if you take photos, reference them in the action (e.g., “Photo 3 – rear scaffold lift”).

Step 5 — Brief the team (5 minutes)

Share the key findings with the people affected (especially if routes, exclusions, or methods change).
Make sure subcontractors hear the actions that apply to them and accept the due dates.

Step 6 — Follow up mid-week (5–10 minutes)

Do a quick check on open actions (especially high-risk items like edges, electrics, excavations).
Update the status and add evidence notes if needed.
If an action can’t be done by the due date, record why and set a new date (don’t leave it drifting).

Step 7 — Close out and carry over (end of week)

Sign off actions only when you have checked the fix on site.
Use the “carry-over from last week” section to list anything still open and the reason (parts on order, needs shutdown, awaiting PC approval, etc.).

Review and approval (sign-off and escalation)

Minimum sign-off: Supervisor (Inspector) and Worker Rep.
When to involve the Site Manager / PC:
- anything that needs programme change, shutdown, or major re-sequencing;
- scaffold alterations, edge protection redesign, or lifting plan changes;
- plant/pedestrian route changes impacting other trades or public protection.
Escalate immediately if a serious risk cannot be made safe quickly (e.g., unstable excavation, missing critical edge protection, uncontrolled lifting area, unsafe temporary electrics).

Check before signing	What you’re looking for
Actions are clear	Each action has a location, owner, and due date; no vague wording like “sort it”.
High-risk items prioritised	Work at height, excavations, lifting, electrics, plant separation have tight due dates and controls in place.
Stop-work recorded (if used)	What was stopped, where, why, and who made it safe is written down.
Close-out is verified	“Done” means checked, not promised.

Recordkeeping (storage, version control, retention)

Where to store: keep a site copy (folder in the cabin) and a master copy in your normal H&S filing system (digital scan is fine).
Naming: use a consistent filename, e.g., Project_Site_WeeklyInspection_YYYY-MM-DD.
Photos/evidence: save with the same date and reference the action number where possible.
Retention: keep completed sheets for the project duration and long enough to demonstrate planned monitoring if asked. Align with your company retention rules and any client/PC requirements.
Audit readiness: be able to show (1) weekly frequency, (2) actions raised, (3) actions closed, (4) repeat issues being managed.

How often to review or update the approach

Weekly: review open actions and recurring issues (same item appearing 2–3 weeks in a row is a red flag).
Monthly (or per phase): look back at the last 4–6 sheets and ask:
- Which issues keep coming back (housekeeping, leads, edge gaps)?
- Do we need a different control (better storage, more barriers, clearer routes, toolbox talk)?
- Are due dates realistic and being met?
After incidents: update what you focus on in the next inspections (target the real causes).

Common mistakes (and how to avoid them)

Pitfall	How to avoid it
Turning it into “tick-box paperwork”	Walk with a worker rep, ask “what’s annoying/unsafe today?”, and write actions that get done.
Vague actions (no location, no standard)	Write what + where + what good looks like. If someone new joined tomorrow, they should still understand it.
No owner / shared ownership	Name one person. If it’s a subcontractor, name their supervisor and tell them on the day.
Due dates that don’t match risk	High-risk controls get same-day or 24-hour dates. Lower-risk housekeeping can be planned but still dated.
Marking actions “Done” without checking	Close out only after a quick verification on site. Add a note or photo reference if useful.
Repeat issues every week	If it repeats, the control isn’t working. Change the system (storage, barriers, routes, supervision), not just the paper.
Not recording stop-work events	If you stop a task, write it down. It shows good control and helps explain any delays.

Worked example (short site scenario)

Scenario: Small refurbishment site. Roofing works starting, new skip delivered, electricians working from temporary power.

Work at height: You find a roof edge where a section of guardrail has been removed for material loading. You stop the task, reinstate edge protection, and record the stop-work note. If loading is ongoing, you raise an action to agree a safe loading method (e.g., designated loading bay with temporary barrier and supervision).
Temporary electrics: You see 240V leads across a walkway and an RCD not being used. You reroute the leads immediately and raise an action: “Fit cable ramp to main walkway and confirm 110V/battery for hand tools where possible” with an owner and due date.
Housekeeping: Waste timber blocking the fire exit route. Action: “Clear and keep fire exit route clear; mark ‘keep clear’ zone” owned by the supervisor, due end of day, then signed off once checked.
Carry-over: Last week’s action “Replace missing tower toe boards” is still open due to parts delay. You note “parts arriving Thursday; tower not to be used until complete” and set the new due date.
