Do quarries need a named competent person?

The Quarries Regulations 1999 are unambiguous: competent advice must be sought, and a competent person named for the site. Not every operator needs a full-time appointment to achieve that. We act as named competent person for quarry operators, a statutory role we have held in practice, giving you a qualified professional on record and on call. Quarry teams are often small, and the regulations exist precisely because the hazards multiply faster than a small team can watch them alone.

Can you support a quarry through an inspection or an audit?

Yes. We audit working quarries: faces and tips, water, plant, blasting arrangements, vehicle movements and isolation, and prepare operators for inspection. The documentation gets built to match your site, because material, extraction method and ground conditions make every quarry unique. The aim is that when the inspector arrives, what is written down matches what is happening on the ground.

What is a quarry health and safety document?

The written document the Quarries Regulations 1999 require every quarry operator to prepare and keep up to date. It identifies the hazards at the quarry, records the risk assessments and controls, sets out the management structure and responsibilities, the rules, and the arrangements for inspection, maintenance, training and emergencies.

What is the workplace exposure limit for silica dust?

For respirable crystalline silica the workplace exposure limit in the UK is 0.1 mg/m³ averaged over an eight hour day. Because silica causes serious lung disease, exposure should be kept as low as reasonably practicable, not just below the limit.

A quarry has the elements of a waste operation and the elements of a construction site, with everything on a larger scale, and at that scale small failures carry large consequences. A geotechnical face movement nobody observed. Falls of material measured in tonnes, not kilograms. Water, which is both part of the environment and a multiplier of hazards. Large plant breaking, sorting and carrying material that varies from site to site, some of it won mechanically, some by blasting. Every site is unique, the teams are often small, and the hazards multiply quickly when management slips. The regulations are unambiguous about what that demands: competent advice must be sought, and a competent person named. We have held that role.

What hazards are associated with quarries?

Quarrying combines heavy mobile plant, unstable ground, water, explosives, dust and noise on sites where teams are often small. The main causes of serious injury and death in the industry are vehicles and mobile plant, falls of material from faces and stockpiles, falls from height, and contact with machinery during maintenance and clearing blockages. Long-term health risks, particularly respirable crystalline silica and noise, harm more people than accidents do.

The Quarries Regulations 1999

The Quarries Regulations 1999 sit alongside general health and safety law and set out what a quarry operator must do. At their centre is the health and safety document: a written record of the hazards at the quarry, how the risks are assessed and controlled, the management structure, the rules, and the arrangements for inspection, maintenance and emergencies. It must be kept up to date.

The regulations also require the operator to appoint competent people, to obtain competent advice, and to make sure everyone working at the quarry, including contractors, understands the arrangements that apply to them.

Named competent person for quarries

Quarry teams are often small, and many operators do not employ a qualified health and safety professional. The regulations do not require a full-time appointment, but they do require competent advice and named competent people for key functions. We act as named competent person for quarry operators: a chartered practitioner on record and on call, a role we have held in practice.

We currently support a multisite aggregates operator with inspections, the health and safety document, plant check systems and preparation for regulator visits.

How often should quarry faces be inspected?

Faces, excavations, tips and stockpiles must be inspected by a competent person at intervals set out in the health and safety document, and before work starts where conditions may have changed, for example after heavy rain, freeze and thaw, or blasting. Where an excavation or tip could be a significant hazard, the regulations require a geotechnical assessment by a suitably qualified person, repeated at least every two years.

The routine inspection is where face movement, undercutting, loose material and water problems are caught early. We build inspection systems that record what was checked, by whom and what was found, so the evidence exists when it is needed.

Blasting and explosives

Where rock is won by blasting, the Quarries Regulations require written rules for the use of explosives, an appointed explosives supervisor, shotfirers who are competent, and a specification for each blast. Explosives storage and acquisition are also covered by the Explosives Regulations 2014. Misfires, flyrock and clearing the area are where the planning gets tested.

Vehicles, plant and isolation

Vehicle and plant movements cause more serious quarry accidents than anything else: reversing, overturning on haul roads and edges, collisions with pedestrians and light vehicles. Segregation, edge protection bunds, haul road design, visibility aids and site rules all need to be documented and enforced.

Fixed plant brings the risk of entanglement during maintenance and when clearing blockages. Isolation and lock off procedures have to work for the plant you actually run, and be followed every time.

Water, lagoons and silt

Water multiplies quarry hazards. Lagoons and silt ponds carry drowning risks and can look solid when they are not; water undermines faces and tips; and flooded workings change the ground. Edge protection, rescue equipment, signage and restrictions on lone work near water belong in the health and safety document.

Silica dust, noise and health surveillance

Crushing, screening and cutting stone produce respirable crystalline silica, which causes silicosis and lung cancer and has a workplace exposure limit of 0.1 mg/m³ averaged over eight hours. COSHH requires exposure to be assessed and controlled, with monitoring and health surveillance where needed. Noise and vibration from plant and tools need the same disciplined approach under their own regulations.

Preparing for inspection

When the inspector arrives, the questions are predictable: show me the health and safety document, the face inspections, the plant maintenance records, the training and competence of your people, and the way contractors are controlled. We audit working quarries against those questions so that what is written down matches what is happening on the ground.
