QNJAC Guidance



The Quarries National Joint Advisory Committee (QNJAC)  is a tripartite body comprising quarrying and extractive industry representatives of employers; employees; the government regulator (Health & Safety Executive, HSE); professional membership bodies; and industry training/educational organizations. 

The purpose of the QNJAC is to debate and develop health and safety policies and implementation strategies.  See Target Zero Vision Statement

The ‘engine room’ of the QNJAC comprises a series of Sub-Committees which focus on particular subject areas or projects, as required.  Approved QNJAC output is principally in the form of Guidance documents which, when confirmed by HSE’s Publications Governance Group,  are published on this website.

To access the QNJAC Guidance easily, the papers are located according to their originating Sub-Committees. Please click on the buttons on the right hand column or click all to view the full range of guidance available.

Guidance on the inspection of lagoons - QNJAC

In this QNJAC guidance you will find information, images and videos covering all aspects of quarry lagoon inspections, it covers the two types of lagoons commonly found in quarries

Below Ground level lagoons which are excavated into the underlying strata usually represent little hazard in terms of geotechnical failure

Above Ground Level Structures which can be concrete or metal constructions but are most commonly embankment type dams. There are some inherent dangers from a number of geotechnical failure mechanisms so they require careful inspection and monitoring.

Guidance on selecting a geotechnical specialist - February 2022

QNJAC has produced some new guidance on the selection of geotechnical specialists.

Where a significant hazard has been identified it is the duty of the operator to ensure that a Geotechnical Assessment is carried out by a Geotechnical Specialist

Whilst the operator appoints a Geotechnical Specialist it remains the duty of the operator to:

  • Ensure that any significant findings and conclusions are recorded by the geotechnical specialist and that the geotechnical specialist signs and dates the document and records his professional qualifications
  • Ensure that any information available to him which may be relevant for the purposes of a geotechnical assessment is made available to the geotechnical specialist undertaking that assessment
  • Ensure that any remedial works identified during the geotechnical assessment are completed by the date specified
