A toolbox talk is a short, focused briefing delivered to the workforce on site, usually on a specific hazard or task: working at height this week, the new traffic management, the method for tomorrow’s lift.
They keep safety live between formal inductions and RAMS briefings, and they are two-way: a good talk surfaces what the workforce is actually seeing.
The record matters: topic, date, deliverer and attendees. If an incident is investigated, evidence of what was briefed and who attended is among the first things asked for.
