Pointing-and-Calling out safety risks

I read this excerpt on Tokyo rail station operators’ Pointing-and-Calling system in James Clear’s Atomic Habits, and immediately thought of its implications for regular tasks carried out in construction and industrial environments. If workers and crews spent a few minutes consciously documenting and evaluating their task journey like this while executing it, think of the potential for identifying risks and reducing risky situations. I understand that some companies are already implementing similar pre-work active hazard identification techniques.

The Japanese railway system is regarded as one of the best in the world. If you ever find yourself riding a train in Tokyo, you’ll notice that the conductors have a peculiar habit.

As each operator runs the train, they proceed through a ritual of pointing at different objects and calling out commands. When the train approaches a signal, the operator will point at it and say, “Signal is green.” As the train pulls into and out of each station, the operator will point at the speedometer and call out the exact speed. When it’s time to leave, the operator will point at the timetable and state the time. Out on the platform, other employees are performing similar actions. Before each train departs, staff members will point along the edge of the platform and declare, “All clear!” Every detail is identified, pointed at, and named aloud.

This process, known as Pointing-and-Calling, is a safety system designed to reduce mistakes. It seems silly, but it works incredibly well. Pointing-and-Calling reduces errors by up to 85 percent and cuts accidents by 30 percent. The MTA subway system in New York City adopted a modified version that is “point-only,” and “within two years of implementation, incidents of incorrectly berthed subways fell 57 percent.”

Pointing-and-Calling is so effective because it raises the level of awareness from a nonconscious habit to a more conscious level. Because the train operators must use their eyes, hands, mouth, and ears, they are more likely to notice problems before something goes wrong.
