Pointing and calling

Pointing and Calling is a safety method used in various industries to reduce human error by involving both physical movement and vocalization. This method is particularly prevalent in Japan, where it is known as Shisa Kanko (指差喚呼), and has been widely adopted in the railway industry, among others. The technique involves a worker pointing at an object, indicator, or display and calling out the status or reading. This action forces the worker to engage multiple senses, thereby increasing focus and reducing the likelihood of overlooking a critical detail.

Overview

The practice of Pointing and Calling integrates the physical action of pointing at an important indication or component with the verbal action of stating the current condition or required action. This method helps in ensuring that the necessary operations are performed correctly and that any indicators are within the required safety parameters. It is especially useful in environments where routine tasks could lead to complacency, and thus, potential errors.

History

The origins of Pointing and Calling can be traced back to Japan in the early 20th century. It was initially adopted by the Japanese railway companies as a strategy to reduce workplace errors and accidents. Over time, its effectiveness in enhancing safety and reducing errors led to its adoption in other sectors and countries.

Mechanism

The effectiveness of Pointing and Calling is attributed to its dual engagement of both physical and cognitive processes. By physically pointing at an item or indicator, the worker is more likely to focus their attention on it. Vocalizing the observation or action reinforces the mental process, making it more likely for the individual to remember the action and notice any discrepancies.

Applications

While most commonly associated with the railway industry, the Pointing and Calling technique has found applications in various other fields. These include aviation, manufacturing, and even healthcare. In each of these sectors, the method has been adapted to fit specific operational needs, but the core principle of combining physical movement with vocalization remains constant.

Benefits

The primary benefit of Pointing and Calling is the significant reduction in workplace errors and accidents. Studies have shown that this method can dramatically decrease the likelihood of oversight errors, contributing to a safer work environment. Additionally, it can enhance the efficiency of operations by ensuring that tasks are performed correctly the first time.

Challenges

Despite its benefits, implementing Pointing and Calling can face challenges. These include resistance from employees who may find the method awkward or embarrassing, and the need for training to ensure that the technique is used effectively. Furthermore, in environments where noise levels are high, the calling aspect of the method may need to be adapted to ensure it remains effective.

Conclusion

Pointing and Calling is a simple yet powerful tool for reducing errors and enhancing safety in various industries. By engaging both the body and mind, it helps ensure that critical tasks are performed with greater accuracy and attention. As industries continue to seek ways to improve safety and efficiency, the adoption of Pointing and Calling is likely to grow.
