Where should actual methane readings be recorded during an on-shift examination?

Recording actual methane readings during an on-shift examination is crucial for ensuring safety protocols are met in mining operations. The correct choice involves documenting these readings in the mine's on-shift examination record book. This practice serves multiple purposes: it creates a formal and accessible record that can be referred to by safety personnel and regulatory agencies, it ensures compliance with safety regulations requiring accurate and timely reporting of gas levels, and it allows for immediate analysis and action if methane levels exceed safety thresholds. This centralized documentation helps maintain a comprehensive record of atmospheric conditions that can be critical in emergency situations and for ongoing assessments of mine safety.

While personal logbooks, digital devices, and safety compliance reports may serve as useful tools for individual tracking or broader compliance documentation, the on-shift examination record book is specifically designed for real-time data collection and is standard practice to ensure relevant information is available to all necessary personnel promptly.
