During an inspection, which documentation must an operator provide?

During an inspection, the operator is required to provide a record of maintenance performed and a log of operating conditions. This documentation is crucial as it indicates that the boiler has been maintained properly and is being operated within safe parameters. Maintenance records show the frequency and type of servicing conducted, which helps in identifying any potential issues that might arise from neglect or improper operation. Additionally, the log of operating conditions provides insights into how the boiler has been functioning over time, including any anomalies or consistent problems that may need addressing.

The other choices, while they may be relevant to some extent in different contexts, do not directly relate to the key requirements during a boiler inspection. A list of all employees working on the boiler, for instance, is not typically a focus during an inspection. Similarly, detailed reports of equipment costs and summaries of energy costs are more financial records rather than operational ones that need to be presented at an inspection. Focusing on maintenance and operational logs aligns with safety protocols and regulatory standards, making it the essential documentation an operator must provide.
