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.
