The circuit diagram shown below is provided to
assist a ‘competent person’ in preparing a written
scheme of examination for a system incorporating
the air compressor(s).
Note: The intervals between examination and
calibration of components, eg pressure vessels,
pressure relief valves etc, will be defined by the
‘competent person’ preparing the written scheme.
In defining these periods the ‘competent person’
must take into account the recommendations of
the component part manufacturer, the Health and
Safety Executive (H & SE) and the British
Compressed Air Society (BCAS).
