Pre-Start Inspection Requirements for Mining in Australia: What You Need to Know

Pre-start inspections are a legal requirement for all mobile plant and equipment operating on Australian mine sites. Getting them wrong, or failing to document them properly, exposes operators, supervisors, and site managers to WHS prosecutions, equipment failures, and serious safety incidents. This guide covers what the law requires, what a compliant check must include, and how digital inspection software eliminates the compliance risk entirely.

The Legal Obligation: What Australian WHS Law Requires

Pre-start inspections in Australian mining are governed by the Work Health and Safety Act 2011 (Cth) and its state equivalents, along with the Work Health and Safety (Mines and Petroleum Sites) Regulation 2022 in NSW, the Mining and Quarrying Safety and Health Regulation 2017 in Queensland, and equivalent instruments in WA, SA, and Victoria.

The core obligation is that mobile plant must not be operated unless it has been inspected and found to be safe before each shift. This applies to excavators, haul trucks, loaders, light vehicles, and any other mobile equipment used on site. The duty sits with:

• The operator, who must conduct and record the check before starting equipment
• The site operator / principal employer, who must establish and maintain a system for pre-start checks, ensure records are kept, and take action on identified defects
• The supervisor, who must verify checks are completed and that defective plant is taken out of service

What a Compliant Pre-Start Check Must Cover

The specific items vary by equipment type, but a compliant pre-start inspection for mobile plant in Australian mining must address the following categories as a minimum:

1. Braking Systems

Service brakes, park brakes, and emergency braking systems must be tested and confirmed operational before the machine moves. Brake fade or reduced effectiveness must be recorded as a defect and the machine taken out of service until rectified.

2. Steering and Tyres

Full steering travel, fluid levels, tyre pressure, tread depth, and visible tyre damage must be checked. Tyre failures are a leading cause of serious incidents on haul roads.

3. Lights and Warning Devices

All working lights (headlights, reverse lights, warning strobes), horns, reversing alarms, and proximity warning devices must be confirmed functional. On many sites this is a hard stop: plant cannot operate without functioning reversing alarms.

4. Fluid Levels and Leaks

Engine oil, coolant, hydraulic fluid, and fuel must be checked. Any visible leaks must be recorded and assessed before operation commences. Hydraulic leaks in particular create fire risk and ground contamination obligations.

5. Rollover Protection and Seat Belts

ROPS and FOPS structures must be visually inspected for damage. Seat belts must be present, fully functional, and not damaged. Operators must use them. A missing or inoperative belt is a reportable defect.

6. Fire Suppression Systems

Where fitted, automatic fire suppression systems must be checked for charge status and activation mechanism condition. Discharge or activation in the previous shift must be investigated before the machine returns to service.

7. Load Restraint and Attachments

Any attachments, buckets, or rigging must be inspected for structural integrity and correct engagement before operation.

Record-Keeping: The Part Most Sites Get Wrong

Completing a pre-start check is only half the requirement. The record of that check must be:

• Signed or authenticated by the operator conducting it
• Timestamped to the specific shift and date
• Linked to the specific plant item by asset ID or registration
• Retained for the regulatory minimum period (typically five years)
• Accessible to the regulator on request, without requiring manual retrieval from paper filing systems

Paper-based systems routinely fail these requirements. Forms go missing, are illegible, lack signatures, or simply cannot be located when an inspector arrives. In Queensland and NSW, the inability to produce records during a compliance audit has resulted in improvement notices and, in serious cases, prohibition notices stopping site operations.

Defect Management: What Happens When a Check Fails

When an operator identifies a defect during a pre-start check, the process must be:

1. The plant is immediately taken out of service and physically tagged or isolated
2. The defect is recorded with sufficient detail for maintenance to act on it
3. A corrective action or work order is raised and assigned to a responsible person
4. The plant does not return to service until the defect is rectified and a sign-off is recorded
5. The full defect-to-rectification record is retained alongside the original pre-start inspection

This closed-loop process is where manual systems break down most severely. A defect noted on a paper form does not automatically create a work order. Maintenance may not see it until the next day. Plant may re-enter service before a repair is confirmed. The record linking the original defect to its resolution often does not exist.

How Digital Pre-Start Inspection Software Addresses Each Gap

Digital inspection software purpose-built for mining operations, such as Pervidi, addresses every one of these compliance gaps by design:

• Offline capability: Checks are conducted on a mobile device underground or in remote areas with no connectivity, then synced automatically when the device is back in range
• Authenticated records: Each check is linked to the operator's login, timestamped, and associated with the specific asset by barcode or QR code scan
• Mandatory field enforcement: Forms cannot be submitted with blank required fields: every item must be answered before the check is marked complete
• Automatic corrective actions: A defect answer triggers an immediate corrective action or work order, routed to the maintenance team in real time
• Plant lockout integration: Integration with maintenance systems can flag plant as out-of-service until the work order is closed
• Instant retrieval: Any check, for any asset, on any date, is retrievable in seconds from the dashboard, with no filing cabinets required

Frequently Asked Questions

Does a pre-start check have to be done every shift, or just at the start of each day?

Every shift. If a machine is operated on a night shift and then a day shift, two separate pre-start checks are required. The check must be conducted by the operator who will operate the plant on that shift.

Can the site manager sign off on a pre-start check instead of the operator?

No. The operator who will use the plant must conduct and sign off on the check. A supervisor or manager may countersign as part of the site's oversight process, but they cannot substitute for the operator's own inspection.

What happens if a pre-start check is missed?

Operating mobile plant without completing a pre-start check is a breach of WHS regulations and can result in an improvement notice, prohibition notice, or prosecution. Following a serious incident, the absence of pre-start records significantly increases the severity of the regulatory response.

Are there approved forms we must use?

Most jurisdictions do not mandate a specific form, but the check must cover all the required items for the plant type. Sites can design their own checklists (digitally or on paper) provided they capture the required information and are retained as records.

Next Steps

If your site is still running pre-start inspections on paper, the question is not whether to go digital. It is how quickly you can make the transition before an audit, an incident, or a regulator visit makes the decision for you.

Pervidi's mining inspection module is designed specifically for this environment: it works offline underground, handles multiple equipment types with tailored checklists, automatically routes defects to your maintenance system, and gives your compliance team a full audit trail accessible from anywhere.
