Pointing and Calling

Introduction: Pointing and Calling

Pointing and Calling is a safety technique designed to reduce human error in high-risk environments. It involves two actions: physically pointing at an object or indicator and verbally confirming its status. By engaging both sight and hearing, the method increases focus, heightens awareness, and helps prevent mistakes.

Background

The technique originated in Japan, where it is known as Shisa Kanko. It became widely adopted in railway operations and later expanded to other industries with safety-critical tasks. Research has shown that Pointing and Calling can reduce human error rates by as much as 85%, making it a simple yet powerful error-proofing tool.

Key Elements/Features

• Dual Action: Combines pointing (visual confirmation) and calling (auditory confirmation).
• Engagement of Multiple Senses: Strengthens concentration and reduces inattentional errors.
• Simplicity: Easy to learn and apply, requiring minimal cost or technology.
• Consistency: Works best when embedded as a standard procedure.

Applications/Examples

• Railways: Train operators confirm signals and track switches aloud.
• Aviation: Pilots and ground crews use it during inspections and system checks.
• Healthcare: Nurses and doctors confirm medication dosages and procedures.
• Manufacturing: Workers verify safety checks on machines or equipment.

Relevance/Impact

Pointing and Calling has proven highly effective in reducing errors and enhancing safety culture. Its strength lies in simplicity—making workers pause, observe, and confirm before acting. By embedding this technique into critical workflows, organisations can significantly reduce risk and improve reliability in operations.
