Pointing and calling is a safety technique widely used in industries such as transportation, manufacturing, and healthcare to reduce human error. The method involves physically pointing at an object or task while simultaneously verbalizing the action being performed or verified. This dual-action process helps individuals stay more focused and attentive to the task at hand by engaging both visual and auditory senses.
Origins and Usage:
- Railways in Japan: Pointing and calling originated in the Japanese railway system in the early 1900s. Known as "Shisa Kanko" in Japan, it is used by train conductors and engineers to ensure that safety checks and tasks are done correctly.
- Reduction in Errors: Studies show that using this method can reduce errors by up to 85%. It forces the brain to process actions more consciously, reducing the likelihood of overlooking important details.
How It Works:
- Point: Physically point to the object, gauge, or task that needs to be checked or acted upon.
- Call: Verbally state what is being checked or done. For example, a train conductor might point at a signal and say, "Signal is green, proceeding."
Benefits:
- Increases focus: Engaging multiple senses helps to stay more alert and avoid distractions.
- Improves teamwork: In group environments, everyone can see and hear what actions are being confirmed, which enhances coordination.
- Reduces fatigue-related errors: Especially in monotonous or routine tasks, pointing and calling can keep workers mentally engaged and less prone to fatigue-related mistakes.
This method has been adopted in various sectors, especially in high-risk industries where safety and accuracy are critical.
