Irish roadworks: SLG, supervision and a clear handover
Understand the different roadworks card roles, identify who is supervising and prepare a handover that makes responsibilities visible.
A useful roadworks handover makes responsibilities visible. Everyone should know which person is supervising the temporary traffic arrangements, which card role they hold and how a concern reaches the right person when work stages or shifts change. Similar card names should not blur different responsibilities.

The distinction in the HSA guidance
For roadworks within Regulation 97’s scope, HSA distinguishes supervision by a competent Signing, Lighting and Guarding CSCS cardholder from the Health and Safety at Roadworks cardholder role. Its guidance describes SLG attendance during installation, modification or removal, regular checks and availability for issues. Where the SLG supervisor is away while work and workers remain on site, HSA describes the on-site Health and Safety at Roadworks cardholder requirement. Read the full conditions in the official FAQ rather than using this summary as a staffing decision.

Check the actual card and course
SOLAS lists Signing, Lighting and Guarding at Roadworks and Health and Safety Roadworks as distinct CSCS categories. Its guidance also sets out recognition routes for overseas qualifications. Do not assume that a similarly named overseas card or a general site induction is automatically equivalent to the category needed for the work.

Prepare a handover the next shift can use
- Identify the current supervisor, relevant card roles and the agreed contact route. Confirm the incoming shift knows who is taking over each responsibility.
- Refer to the current plan and risk assessment. Explain which stage is in place, what changed during the shift and which matters still need attention.
- Describe any reported defect, unresolved concern or departure that has been escalated. Record the action agreed and the person responsible for following it up.
- Keep arrangements for breaks, shift changes and availability explicit. Ask the responsible employer or project lead to confirm coverage rather than inferring it from a name on a roster.
- Use the organisation’s record process so the next person can find the latest information. A handover message should point to the controlled record rather than create an unofficial competing plan.
Keep questions within the right role
A person who notices a problem needs a clear way to report it. That does not mean every worker has authority to redesign the arrangements. Before the shift, make the distinction between raising a concern, correcting something within an authorised role and deciding on a configuration change understandable to the whole team.
This guide concerns the Republic of Ireland. For Northern Ireland, start with the applicable UK and Northern Ireland authorities instead of transferring these CSCS role descriptions across the border.
