What is a banksman, and when does a site need one?

What a banksman does

A banksman is the person standing where the driver can't see: guiding a reversing wagon off the gate, walking a crane load into a laydown area, keeping pedestrians out of a swept path while a telehandler works a stack. The job title varies across the industry, some sites call it a signaller, some run it as a combined slinger/banksman role, but the function is the same. A second set of eyes doing the thing the vehicle operator physically cannot do alone.

Under the LOLER and PUWER framework, this is about controlling risk from vehicles and lifting operations on site. HSE guidance on vehicles at work, and the CDM regime more broadly, expects you to manage reversing, loading and unloading risks, and a banksman is one of the standard controls for that.

When a site needs one

The honest answer: whenever reversing or loaded-crane movement actually happens near people or other plant, and the driver's view is obstructed. That covers more of a live site than most inductions let on.

• A wagon reversing onto site past a pedestrian walkway with no clear sightline from the cab.
• A crane or telehandler slewing a load over or near an access route still in use.
• A confined yard where multiple vehicles share a single turning circle and blind corners.
• Any reversing movement in a working compound where the traffic management plan can't guarantee a vehicle-free path.

If your traffic management plan already routes vehicles so reversing never happens near people, you may not need one for that movement. But most working sites change week to week. A laydown area creeps a few metres, a temporary fence line moves, a new subcontractor stacks material somewhere that closes off the sightline the plan assumed. That's where a banksman gets added at short notice, because the layout on the ground stopped matching the layout on paper.

Banksman requirements construction sites check

There's no single named qualification that "makes" someone a banksman in law. What inspectors and principal contractors look for in practice:

• Training appropriate to the task. Many sites run CPCS or in-house signaller training, some require it before badging someone onto a reversing or lifting job.
• High-vis distinct from general site PPE, so the driver can pick them out against the compound.
• Standard hand signals or a confirmed radio protocol agreed with the operator before the move starts, not improvised mid-lift.
• A position where the banksman can see both the driver and the hazard. Standing where the driver can see you but you can't see the load is a common finding on audit.

Most audits flag a banksman positioned in the wrong place, or needed and not provided, because the laydown area or access route shifted since the last walk of the logistics plan. A missing qualification is rarely the finding. A plan that no longer matches the ground usually is.

Why this keeps slipping

Traffic management and logistics plans get drawn once, then the site moves around them all project long. Laydown areas creep into swept paths. A stored skip narrows a route a banksman's zone depended on. Edge protection goes up late on a route already carrying plant. None of that shows up until someone walks the site again, and a full manual walk of the whole logistics plan every week is more than most HSE teams have hours for.

That's the gap Site Logistics Audit is built around: a weekly overhead read of the site that flags laydown encroachment, blocked access routes and missing edge protection as a site-wide list, so you know where the plan and the ground have drifted apart before it turns into a near-miss involving a reversing vehicle nobody was banked for.

If your site's layout has moved since the last full walk, that's worth checking before your next inspection.
