How it shows up on site
One reason the focus four hazards in construction - common mistakes deserves its own toolbox talk is that the hazard usually grows from a chain of small changes rather than one dramatic mistake. A crew gets comfortable, the environment changes, a control is missing, access becomes awkward, or the task starts to move faster than the original plan.
Examples help make that sequence obvious. A walkway gets cluttered, a cord gets damaged, a lift point is chosen too quickly, or weather changes the ground underfoot. Each change feels small on its own, but together they turn familiar work into something riskier than it looked at first glance.
