Why Task Risk Sits with the Supervisor

Organisations assess risk at several levels. At the top, a site or facility risk assessment looks at major hazards: fires, explosions, structural collapse, toxic releases. In the middle, procedures and generic assessments describe how routine work should be done. At the bottom is the task: this crew, this equipment, this location, today.

Most injuries happen at the task level. The person who knows the task, the crew and today's conditions best is the frontline supervisor. That is why this course treats the supervisor as the owner of task risk. Managers and safety advisers support the supervisor, but they are rarely standing at the job when it changes.

Worked example: a good generic assessment, a bad day

A water treatment plant had a well-written generic assessment for replacing dosing pump hoses. On the day, the usual technician was on leave. His replacement had changed hoses on a different pump model. It was raining, so the crew worked under a temporary cover with poor light. A chemical line upstream had not been fully drained. The generic assessment was correct, but none of these task-level facts were in it. The technician received a chemical splash to the face shield. The investigation found that nobody had checked the generic assessment against the day.

Worked example: the supervisor who checked

At a warehouse, a supervisor was given a generic assessment for racking repairs. She noticed that the area under the damaged bay was still being used by forklift traffic, which the assessment assumed would be closed. She arranged a closure with the warehouse manager before work started. The difference between the two cases is not the paperwork. It is the supervisor matching the paper to the day.
