Site Access Traffic Marshals

Site Access Traffic Marshals (SATM) are an important part of safe and effective construction site operations. CLOCS offers SATM training to help ensure the safest construction vehicle journeys in/out of sites – a critical part of the CLOCS Standard.

Site Access Traffic Marshals

Site Access Traffic Marshals (SATMs) stationed at the site entrance are the primary and critical interface between the site, fleet operations and the public. They ensure only authorised vehicles and people enter the site, while also ensuring vehicles entering and leaving the site do so safely and efficiently.

Most sites also have Banksmen who guide vehicles within the site hoardings – these are distinct roles and cannot be done concurrently by the same person though often personnel are rotated between roles

SATMs are critical to the implementation of the CLOCS Standard. Competent SATMs are recognised by progressive contractors as essential members of the team as they improve site efficiency and productivity. CLOCS SATMs are equipped with specific skills, attitudes, and have the confidence to effectively implement CLOCS at the gate.

Become a CLOCS-approved SATM Training provider

CLOCS SATM training must deliver the CLOCS Competency Framework, which was developed to lift the quality of training. Training providers wishing to deliver CLOCS ‘approved’ training are assessed by the SATM review panel. Applicants are required to provide detailed evidence of proposed training delivery, quality management systems and past performance as the basis of assessment.

Download the SATM approval requirement and process. Training delivery and course content will be formally reviewed annually to ensure standards are being maintained.

Any organisation with the right experience, skills and systems can apply for their training to be CLOCS-approved. Please contact
