Use the correct authority before any machinery task begins.
This page provides general orientation only. The approved manual for the exact machine model and configuration, the site-specific risk assessment and procedures, applicable local law, and direction from a competent authorised person take precedence.
Review the Authority Framework
Safety precedence
General web guidance cannot authorise work.
Only the controlled documents and responsible people for the actual machine, site, jurisdiction and task can define an approved method. Where sources appear inconsistent, stop the task and obtain a documented resolution through the site’s safety-management process.

Authority framework
Establish the documents, duties and decisions that govern the task
These controls operate together. This page does not replace, relax or reinterpret any machine-specific instruction, site control or legal obligation.
-
Model documentation
Confirm the exact manual and machine configuration
Use controlled documentation applicable to the machine identity, installed options, controls and current modification state. A manual for a similar product cannot establish the operating, isolation, inspection or maintenance method for another configuration.
Review Machine Categories -
Site risk assessment
Assess the actual task and operating environment
Consider material behaviour, access, traffic, utilities, adjacent processes, staffing, foreseeable intervention and emergency arrangements. Reassess when equipment, layout, material, operating mode or work organisation changes.
Prepare Site Requirements -
Local requirements
Identify applicable law and mandatory site controls
Legal duties, inspection regimes, guarding expectations, electrical requirements and worker-protection rules depend on jurisdiction and use. Obtain qualified local review; information written for another market does not demonstrate compliance.
Review International Coordination -
Competent control
Assign authority according to task and demonstrated competence
Training attendance alone does not authorise every task. The site should define who may operate, inspect, isolate, diagnose, maintain, modify and return equipment to service, including supervision and escalation limits.
Discuss Engineering Scope -
Energy isolation
Control supplied and stored energy before exposure
The approved isolation procedure must address all relevant electrical, hydraulic, pneumatic, mechanical, gravitational and residual-energy states. Verification, restraint and return-to-service requirements must be defined for the actual task by authorised personnel.
Review Maintenance Boundaries -
Emergency readiness
Plan response without creating further exposure
Define alarm, shutdown, communication, first-response, rescue-access and external-support arrangements for the site. Emergency actions must be practised and coordinated; unplanned entry into a hazard zone can compound the event.
Review Process Interfaces
No entries match the selected filters.
Hazard awareness
Screen the complete task, not only normal production
Risk review should cover foreseeable operation, cleaning, adjustment, blockage response, inspection, maintenance and abnormal conditions.
-
Mechanical hazards
Crushing, shearing and trapping zones
Identify moving structures, closures, feed and discharge interfaces and locations where material movement can create an exposure. Safeguards must remain effective for the defined operating mode.
-
Control hazards
Unexpected start or automatic movement
Review remote commands, stored sequences, restart conditions, interconnected equipment and fault recovery. A stopped control state must not be assumed to be an isolated state.
-
Stored energy
Pressure, gravity and retained mechanical force
Identify energy that can remain after a supply is disconnected, including raised or compressed components and loaded material. Use only the approved task-specific method to achieve and verify a safe state.
-
Material hazards
Ejection, instability and unknown contents
Material can shift, spring, fall, leak or conceal incompatible objects. Characterise the stream and define rejection and escalation rules before it enters the machinery process.
-
Workplace interfaces
Access, falls, vehicles and adjacent work
Coordinate pedestrian routes, mobile equipment, platforms, housekeeping, lighting and concurrent tasks with machinery controls. The installation boundary includes the workplace around the machine.
-
Environmental hazards
Dust, noise, heat, fire and substances
Assess exposure and ignition conditions using site knowledge and material evidence. Ventilation, detection, personal protection and emergency controls require competent selection for the actual environment.
No entries match the selected filters.
Controlled work
Maintain authority through the complete task lifecycle
A safe plan remains conditional on the equipment and workplace matching the approved assumptions.
- 01
Define the task
Identify scope, people, interfaces, hazards, documents and the person authorised to approve the work.
- 02
Establish the safe state
Apply and verify the approved controls for access, isolation, restraint and surrounding activities.
- 03
Work within control
Follow the authorised method and maintain communication, boundaries, tools and supervision defined for the task.
- 04
Respond to change
Stop and reassess when conditions, personnel, material, equipment state or scope differ from the plan.
- 05
Authorise return
Complete inspection, safeguard restoration, clearance, communication and formal return-to-service requirements.
