Stability and design of the operation
Faces, slopes, stockpiles and tipping areas must form part of technical planning. Geology, water and the progression of work affect their stability; judging the appearance of the ground during a visit is not enough.
HSE links quarry prevention to extraction design and geotechnical studies. Changes to faces, roads or accumulations require review before they become routine practice.
Traffic and mobile equipment
Workplace traffic must account for heavy vehicles, pedestrians, visibility, crossings and edges. Routes, their maintenance and the separation of activities are preventive decisions as well as operational ones.
Loading, unloading and manoeuvring should be observed under real conditions. A route that is safe when dry may change with mud, reduced visibility or the presence of a contractor. Who communicates and authorises changes must be decided.
Dust, noise and other exposures
Drilling, crushing, transport and cleaning can generate dust. The presence of respirable crystalline silica depends on the material and process: it must be identified and assessed, without inferring safety from an absence of visible dust.
Prevention must also review noise, vibration and environmental conditions. Capture, emission reduction and maintenance are selected for each source; personal protective equipment does not replace assessment or control at source.
Maintenance and non-routine tasks
Cleaning a facility, clearing a blockage or working on machinery can expose people to movements and energies not encountered during normal operation. Maintenance safety requires defined procedures, resources and responsibilities.
Competence must match the specific task. In underground mining, ventilation, ground control and means of escape also need specialist analysis; quarry measures cannot simply be extrapolated.
Coordination and emergency response
Internal and external teams must know the authorised areas, interactions between activities and conditions requiring work to stop. Supervision must extend to shift changes and occasional interventions.
The response plan must reflect the actual location of work, communications and access for assistance. Its usefulness is checked through exercises and incident reviews, not merely by retaining the document.
Hypothetical example: relocating an extraction face
A quarry moves its extraction point. Before opening the new route, it reviews stability, pedestrian crossings, maintenance access and dust dispersion. It informs hauliers and operators and verifies conditions on site.
The review records responsibility and evidence of the change. In this way, expansion of the operation does not render the preventive arrangements that worked in the previous area obsolete.
