Importance and Maintenance of Logs in Boiler Plant Operations

Logs are crucial tools in boiler plant operations, serving as reliable records for decision-making, safety, and legal purposes. While modern plants use electronic devices for data recording, handwritten logs remain indispensable due to their durability and legal credibility.

Key Points:

1. Purpose and Importance of Logs

   • Logs help operators make informed decisions, verify historical data, and improve plant performance.

   • They protect the operator and employer legally, especially during incidents or lawsuits.

   • Logs serve as evidence of operational history and demonstrate operator skill.

2. Limitations of Electronic Data

   • Electronic devices may not record all necessary information.

   • Data can be lost or destroyed during incidents and may be easily altered.

   • Handwritten logs have survived severe plant incidents and are more trusted in court.

3. Best Practices for Log Keeping

   • Use a bound logbook with consecutively numbered pages to prevent tampering.

   • Maintain both handwritten and electronic logs for comprehensive record-keeping.

   • Duplicate electronic logs should be stored securely offsite on non-erasable media.

4. Types of Logs

   • Operator’s Log: Records daily activities, data readings, visitors, and problems.

   • Water Treatment Log: Tracks water analysis and chemical additions.

   • Maintenance and Repair Log: Documents maintenance activities for easy reference.

   • Visitor’s & Contractor’s Logs: Used when there are frequent visitors/contractors.

   • Recorder Charts: Continuous records of pressures, temperatures, and levels.

5. Creating an Effective Log

   • Custom logbooks are preferred for efficiency, consistency, and professionalism.

   • Preprinted logs with assigned data spaces and carbon copies improve record management.

   • A hybrid system combining bound paper logs and computerized databases offers the best approach.
