Daily SWMS Sign-On Done Properly: An Example Briefing and Record

A proper SWMS sign-on means every worker has been briefed on the safe work method statement for today's site and task, understands the hazards and controls, has had a chance to raise concerns, and then signs. The signature records the briefing; it doesn't replace it. A good daily briefing for a traffic crew takes ten to fifteen minutes.

Work on or next to a road used by traffic is high-risk construction work, so a SWMS is required before work starts. The trouble is that sign-ons drift into a clipboard passed around the ute while people are still putting boots on. This guide gives an example briefing script, a record template and the common gaps to avoid. For what the SWMS itself must contain, see SWMS for traffic control. This is general guidance, not legal advice; check your duties with your state regulator.

What a sign-on is actually for

A SWMS sign-on does three jobs:

1. Communicates. Every worker hears the hazards and controls for this site today.
2. Consults. Workers can raise concerns, local knowledge or problems with the plan before work starts. WHS laws require consultation with workers on health and safety matters that affect them.
3. Records. There is evidence of who was briefed, on what, and when.

If any of the three is missing, the sign-on is weak. A list of signatures with no briefing communicates nothing. A briefing with no chance to speak is not consultation. A briefing with no record cannot be shown later.

Before the briefing: what the supervisor prepares

Arrive early enough to prepare. The supervisor should have:

• the SWMS for the task, current version
• the approved traffic guidance scheme (TGS) and any permit or road occupancy conditions
• the day's weather forecast
• the crew list, with tickets checked for each person
• the emergency details: nearest hospital, first aider, assembly point, site address for triple zero
• anything that changed since yesterday: new stage, new crew member, incidents, client requests

Walk or drive the site first if possible, so the briefing reflects what's really there.

A few habits make the briefing work better. Hold it somewhere quiet, away from running plant and passing traffic. Get everyone to stop what they're doing and face you; nobody signs while still loading the ute. Hold up the TGS so people can see it rather than describing it from memory. Keep it to the point, and don't read the whole SWMS aloud word for word: talk through the hazards and controls that matter today and make the document available for anyone who wants to read it.

Example briefing script

Here is how this plays out on a typical job. The site is a lane closure with stop/slow on a two-lane road for stormwater pit works. The crew is a supervisor, TC 1, TC 2 and TC 3 (relief), plus a three-person civil crew from the client. It's 6:10 am.

1. Introduction (1 minute). "Morning all. This is the SWMS briefing for traffic control at the stormwater job. We're on day three. Anyone who hasn't worked with us before? (A new civil labourer raises a hand.) Good, we'll make sure you're across the site."

2. The job and the TGS (3 minutes). "Same TGS as yesterday, stop/slow both ends, single lane past the pit. Today the work moves 40 metres east, so the western station moves with it as per the stage 2 drawing. TC 1 west, TC 2 east, TC 3 relief and rotation every hour. Here's the TGS; have a look at where your station is."

3. Hazards and controls (4 minutes). "Main hazards: traffic not stopping, the excavator and tipper reversing, the open pit, heat this afternoon. Controls: stations off the road with escape routes, which I'll walk with each of you; spotter for every reverse, and the tipper does not reverse without one; pit barricaded at all times; water and shade at the ute, rotation every hour, and tell me if you feel unwell."

4. What's different today (2 minutes). "School pick-up at 3 pm brings more pedestrians on the north footpath. TC 3 will cover pedestrians from 2:45. Forecast says wind picks up after lunch, so check your signs on every rotation."

5. Communication and emergencies (2 minutes). "Radio channel 4, backup channel 6. Radio check before we release anything. If radios fail, both ends hold on STOP. Emergency: first aider is me, kit in my ute, nearest hospital is listed on the sheet, the site address is on the sheet for triple zero. Emergency vehicle: use the call we practised."

6. Questions and concerns (2 minutes). "Anything you've noticed, anything you're not happy with?" (TC 2 says the eastern approach sun is bad in the morning. Supervisor agrees to check the station on the drive-through and adjust within the TGS.)

7. Sign-on (2 minutes). "If you've understood and you're happy, sign on. If you're not happy, say so now."

The new labourer gets a separate five-minute walk of the site with the supervisor before starting.

Example continued: a late arrival and a mid-shift change

The morning briefing is only the start. The same shift shows how the record should grow through the day.

1. 7:20 am, late arrival. A tipper driver from the client's subcontractor arrives for the first time. The supervisor stops him at the ute, not at the work area. In five minutes they cover where trucks enter and leave, that no reversing happens without the spotter, where the pit is, the radio call for emergencies and where to wait. The driver signs on a separate line: "7:20 am, briefed by supervisor, tipper driver, ticket sighted."
2. 9:00 am, rotation. TC 3 relieves TC 1 on the western station. No new sign-on is needed, because rotation was covered in the morning briefing and both are already signed on.
3. 11:15 am, task change. The client asks to close the lane fully for 30 minutes so a crane truck can lift a precast pit lid. That method needs its own approval and arrangements, which the client confirms are in the TGS as a separate stage. The supervisor stops work, gathers the whole crew, and briefs the change: new positions, the crane exclusion zone, who holds traffic and where, and how traffic is released afterwards. Everyone signs the re-brief line with the time.
4. 11:50 am. The lift is done, the stage reverts to stop/slow, and the supervisor tells the crew by radio and in person. The return to the earlier layout is noted in the record.
5. 2:30 pm. The wind picks up as forecast. The supervisor reminds everyone on the radio to check signs on rotation, which was already in the morning briefing, and notes it in the site diary.
6. 3:30 pm, end of shift. The supervisor reviews the sign-on sheet: all names, all times, the re-brief and the late arrival recorded. It goes in the job file and is sent to the office.

The record at the end of the day tells a reader exactly who knew what, and when. That is what makes it useful if anything is later questioned.

The sign-on record

A good record captures more than names. Use something like this.

Keep the record with the job file. The principal contractor may ask for it, and so may the regulator after an incident. The traffic control site diary guide covers the other records to keep alongside it.

When to brief and sign on again

A sign-on covers the work described at that time. Re-brief and sign on again when:

• the task changes (moving from stop/slow to a full closure, for example)
• the TGS stage changes in a way that affects hazards or positions
• the SWMS is revised after an incident or a near miss
• a new worker or visitor arrives
• conditions change significantly, such as a storm or a night shift continuing into fog
• a worker returns after leaving site for a long period

The re-brief can be short, but it must be recorded. See also when traffic management plans need review.

Common gaps and how to fix them

The same principles apply to visitors. A client's engineer arriving to inspect the pit needs a briefing on where to walk and what to avoid. The site visitor briefing guide covers that.

Paper or digital sign-on

Both work if the briefing is real. Paper is simple but can get wet, lost or left in the ute. Digital sign-on on a phone records the time automatically, can show the SWMS document itself, and keeps records in one place for the office. The risk with digital is that it becomes even easier to sign without listening, so the in-person briefing remains essential.

For guidance on SWMS and high-risk construction work, check with SafeWork NSW, Safe Work Australia or your state regulator.

Next steps

Try the seven-part script at your next pre-start and time it. If you want to move sign-on off paper, TrafWise includes SWMS sign-on and signatures in the crew app, with pre-start checks on the same screen, so the record sits with the shift.
