This Log Book closely matches the UK Health and Safety Executive's (HSE) guidance BG01, Section 8 and INDG436 on the information that should be recorded. However it remains the responsibility of the operator on site and the 'responsible person' to ensure that information is maintained and recorded correctly. At the end of each week an additional form summarising boiler operation must be completed and countersigned by the responsible person.

The one week per page layout of the Log Book has been laid out to meet the needs of Typical Arrangements 2, 3 and 4 installation as specified in BG01. This is the most common control arrangement being used in the UK. If your operation remains within Typical Arrangement 1 configuration; comprising low integrity water level controls mounted in external chambers; more frequent testing of limiters is required. This additional testing must be recorded within the comments section of the daily record pages. Where Typical Arrangements 3 and 4 are employed, after a suitable risk assessment, the period between testing may be extended from daily to up to 72 hours, and from weekly to a suitable test period, e.g. as required by EN12953.

All tests and records must be undertaken and recorded by a trained boiler operator. Untrained persons can work on plant but must be adequately supervised. A correctly trained operator will deliver improved efficieny and reliability, delivering reduced fuel costs, lower emissions and extending the operational life of your boiler plant.
