Why the pre-shift inspection matters

Under the Coal Mining Safety and Health Act 1999, the open cut workings must be examined and confirmed safe before people work in them. The OCE’s signature on that examination is a legal statement. A structured checklist ensures nothing is missed and that the record stands up to scrutiny.

The core pre-shift checklist

Ground and geotechnical conditions

• Highwall and lowwall stability — cracking, tension gaps, scaling or fresh fall material
• Batter and bench condition against design
• Evidence of wall movement or monitoring alarms since the last examination
• Water accumulation, seepage or sump levels

Roads, access and mobile plant

• Haul road condition, windrows, edge protection and signage
• Ramp grades, intersections and sight lines
• Dust and visibility conditions
• Parking-up areas and go-lines

Environmental and other hazards

• Weather — rain, lightning, heat or wind that may change conditions during the shift
• Blasting exclusion zones and misfire controls
• Electrical apparatus, trailing cables and isolation points
• Spontaneous combustion indicators where relevant

Link every hazard to a TARP

A checklist that only lists hazards is incomplete. The value comes from connecting each finding to a Trigger Action Response Plan (TARP) so that when a condition crosses a trigger — say, a monitoring prism accelerates or rainfall exceeds a threshold — the required actions are unambiguous and already agreed. Good OCEs use TARPs to turn observation into decisive action.

Record it properly

The statutory record should capture what was examined, the conditions found, the controls in place, any hazards raised, and who was notified. Legible, complete and timely records are as important as the inspection itself — they are the evidence that the examination happened and that the mine was safe to enter.

Common findings that slip through

• Overnight rain changing wall and road conditions before day shift
• Windrows below height at active dump edges
• Deteriorating sight lines at busy intersections
• Housekeeping and trip hazards around workshops and go-lines

Digitising the pre-shift examination

Increasingly, mines are moving pre-shift examinations onto digital and visual hazard-management tools — geotagging findings, attaching photos, and giving supervisors live visibility of conditions. This makes records more consistent, easier to audit and faster to act on.

What is an Open Cut Examiner?

An Open Cut Examiner is a statutory official appointed under the Coal Mining Safety and Health Act 1999 (CMSHA) and the Coal Mining Safety and Health Regulation 2017. The OCE holds a certificate of competency issued by the Queensland Board of Examiners and is responsible for examining the open cut workings of a coal mine to identify hazards and confirm that the mine is in a safe condition for people to work.

In practice, the OCE is the person who signs off that a section of the pit has been inspected and is safe to enter at the start of a shift. It is a role defined by legal accountability, not just experience.

The legal basis for the OCE role

The OCE’s duties flow directly from Queensland’s coal mining safety legislation. Every coal mine must have a Safety and Health Management System (SHMS), and the OCE operates within that system to discharge specific statutory obligations, including pre-shift and workplace examinations, hazard identification, and record-keeping. Because these duties are set out in law, they cannot simply be delegated away — the appointed OCE carries personal responsibility for the examinations they sign.

Key duties of an OCE

• Pre-shift inspections — examining the open cut workings before each shift to confirm they are safe to enter.
• Workplace examinations — checking active work areas throughout the shift for emerging hazards.
• Hazard identification and reporting — recognising ground, geotechnical, mobile-plant, electrical and environmental hazards and recording them.
• TARP monitoring — applying Trigger Action Response Plans when conditions change (for example, wall movement or weather).
• Statutory record-keeping — completing and retaining the legal records of each examination.
• Communication — briefing crews and the mine’s supervisors on conditions and controls.

When does your mine need an OCE?

Any operating open cut coal mine in Queensland needs OCE coverage for every production shift. Demand for qualified OCEs also spikes during planned shutdowns, roster gaps, sudden absences, and ramp-ups on new projects. Because the certificate of competency takes years to earn, many operators cannot simply hire a permanent OCE at short notice — which is where contract OCEs become invaluable.

Engaging a contract OCE

A contract OCE is a fully ticketed examiner engaged on a short- or long-term basis to provide statutory coverage. The right contractor arrives inducted, current on their certificate, and matched to your commodity and site conditions — ready to keep production moving without compromising compliance.

Red Lion Safety helps current and aspiring Open Cut Examiners perform at their best — through tailored OCE mentoring and oral-exam preparation, SOP and risk-assessment support, and independent SHMS audits. Get in touch and we’ll be in contact within one business day.
