The posting

Role Purpose

The Isolation Officer is responsible for the safe coordination, execution, verification, and control of all plant energy isolations associated with maintenance, inspection, commissioning, breakdown, shutdown, and operational activities within the processing plant. The role is critical to ensuring zero harm through the effective application of Lockout/Tagout (LOTO), Permit-to-Work (PTW), and hazardous energy control systems across the Gamsberg Phase 2 concentrator, with particular emphasis on the Crushing Plant, Gyratory Crusher, Conveyors, Milling, Flotation, Pumping, and associated process equipment. The Isolation Officer ensures that all electrical, mechanical, hydraulic, pneumatic, gravitational, thermal, and stored energy sources are positively isolated, verified, controlled, and safely reinstated in accordance with site procedures, MHSA requirements, and operational standards.

Key Responsibilities

  • Isolation Management & Hazardous Energy Control
  • Coordinate and execute safe isolations for planned maintenance, breakdowns, shutdowns, inspections, and commissioning activities.
  • Implement and enforce Lockout/Tagout (LOTO) procedures across the processing plant.
  • Ensure all isolation activities are conducted in accordance with approved isolation procedures, risk assessments, and plant operational requirements.
  • Identify all primary and secondary energy sources prior to commencement of work.
  • Ensure positive isolation and verification of equipment before work is released to maintenance or operations personnel.
  • Prevent uncontrolled release of hazardous energy that may result in injury, equipment damage, or plant downtime.

Crushing Plant & Gyratory Crusher Isolation

  • Lead and coordinate isolations associated with the Gyratory Crusher, apron feeders, conveyors, transfer chutes, vibrating screens, lubrication systems, dust extraction systems, and associated auxiliary equipment.

Verify isolation of:

  • Crusher drive motors
  • Hydraulic systems
  • Lubrication systems
  • Conveyor drives and take-ups
  • Pull-cord and interlock systems

Stored mechanical and gravitational energy sources

  • Ensure conveyor sequence interlocks and control logic are safely isolated prior to maintenance intervention.
  • Coordinate isolations during crusher liner changes, blockage clearing, maintenance shutdowns, and commissioning activities.
  • Ensure all guarding, pull cords, emergency stops, and safety devices are reinstated before plant startup.

Process Plant Isolation Coordination

Coordinate isolations associated with:

  • SAG and Ball Mills
  • Pumps and slurry systems
  • Flotation cells and blowers
  • Thickeners and filter systems
  • Reagent systems
  • Compressors and utilities
  • Electrical substations, MCCs, switchgear, and VSD systems
  • Water reticulation and process services

  • Verify that isolations are correctly applied before releasing equipment for work.
  • Maintain strict control of lock registers, isolation boards, keys, tags, and lock allocation systems.
  • Participate in pre-task risk assessments, toolbox talks, and work planning activities.

Verification & Zero Energy Testing

  • Conduct physical verification of all isolations prior to work commencing.
  • Confirm zero energy state using approved testing methods and equipment.

Verify absence of:

  • Electrical voltage
  • Hydraulic pressure
  • Pneumatic pressure
  • Rotational movement
  • Stored mechanical energy
  • Gravitational movement potential
  • Ensure equipment cannot be started locally, remotely, or automatically while maintenance activities are underway.

Shutdowns, Commissioning & Operational Readiness

  • Support commissioning, operational readiness, and shutdown execution activities through disciplined isolation management practices.
  • Coordinate isolations during:
  • C1 to C5 commissioning phases
  • Functional testing activities
  • Dry and wet commissioning
  • Maintenance shutdowns Statutory inspections
  • Assist in developing safe isolation procedures and plant-specific isolation philosophies during commissioning and startup phases.
