Before the work starts, somebody says out loud what the task is, what could hurt you, what is being done about it, who does what, and what would make you stop.
Most of what goes wrong was known by someone on site and never said. The conversation is what moves it from one person's head into everyone's.
The stop conditions are the part that gets left off, and they are the reason the conversation works. Agreeing beforehand what would make everyone stop means that when it happens, stopping is following the plan rather than someone losing their nerve. Nobody has to argue for it in the moment.
Check yourself: You are about to start. What is the one question worth asking out loud?
Answer: Ask who verifies isolation before any work begins.
Isolation is the control everything else rests on, and "someone did it" is not a name. Asking who makes it one person's stated responsibility instead of an assumption shared by everybody and held by nobody.
