Objective 01: Plant Maintenance Flashcards
What is a critical factor in the successful operation of all types of equipment?
Proper maintenance
Maintenance
The combination of all technical and administrative actions, including supervision actions, intended to retain an item in, or restore it to, a state in which it can perform a required function.
What does ‘item’ refer to in the formal definition of maintenance?
All hardware and associated software such as equipment, components, devices, systems, and other physical assets.
What does ‘required function’ refer to in the formal definition of maintenance?
A combination of design (which defines the limits of use) and operation (which describes its actual use)
What does ‘to retain an item in, or restore it, to a state’ refer to in the formal definition of maintenance?
The purpose of maintenance is either to perform actions that keep equipment performing as required by doing preventive maintenance (to retain), or to repair it when it has failed by doing corrective maintenance (to restore).
What does ‘combination of all technical and administrative actions, including supervision action” refer to in the formal definition of maintenance?
Maintenance is not only the execution of maintenance tasks, but also administrative actions (such as planning and scheduling) and supervisory actions (such as hiring and training skilled personnel)
What are the 4 categories of the major aspects of maintenance?
- Overall Planning
- Preventive Maintenance
- Corrective Maintenance
- Maintenance Enhancement
What does Overall Planning entail for maintenance?
- management of maintenance
- maintenance program development
- maintenance planning and scheduling
What does Preventive Maintenance entail?
- maintenance planning and scheduling
- maintenance execution
- maintenance assessment
- maintenance improvement
What does Corrective Maintenance entail?
- Maintenance Planning and Scheduling

- Maintenance Assessment
- Maintenance Improvement
What does Maintenance Enhancement entail?
- maintenance improvement
- maintenance program development
- maintenance planning and scheduling
Whose responsibility is Management of Maintenance?
Supervisors and Managers
What does Management of Maintenance include?
- Developing a high-level maintenance strategy for an organization
- Managing, coordinating, and supervising maintenance groups
- Providing finances and managing maintenance budgets
- Providing resources for maintenance, such as skilled staff, spare parts and materials, maintenance facilities, tools and support equipment, and manual and computerized information systems
Whose responsibility is the Maintenance Program Development?
Maintenance planners with involvement from maintenance personnel
What does Maintenance Program Development include?
- Identifying preventive maintenance tasks
2. Determining support resources needed for preventive maintenance tasks
Whose responsibility is the Maintenance Planning and Scheduling
Maintenance Planners
What does Maintenance Planning and Scheduling include?
- Planning resources needed to carry out specific preventive and corrective maintenance tasks
- Scheduling maintenance tasks within the limits of available resources
Whose responsibility is Maintenance Execution?
Maintenance Staff
What does Maintenance Execution include?
- Obtaining resources, e.g. spare parts and specialized tools
- Traveling to the work site
- Following safety and environmental procedures
- Dismantling, repairing, and reassembling equipment
- Investigating and diagnosing failures
- Documenting the results of work done and resources used
Whose responsibility is Maintenance Assessment?
Maintenance Planners and Maintenance Personnel
What does Maintenance Assessment include?
- Assessing and documenting the success of maintenance actions
- Measuring maintenance performance indicators
- Performing failure analysis, especially for major failures
- Assessing equipment availability, reliability, and cost
- Reviewing the success of preventive maintenance programs
Whose responsibility is Maintenance Improvement?
Maintenance Staff and others, e.g. design engineering
What does Maintenance Improvement include?
- Design improvements or modifications
- Changes to operating procedures
- Changes to maintenance procedures
- Improvements to preventive maintenance tasks and resources
What are 2 ongoing cyclical processes that occur in maintenance?
- Maintenance Cycle
2. Continuous Improvement
What does the Maintenance Cycle entail?
Maintenance tasks are identified or triggered, planned, scheduled, executed, and assessed
What does the Continuous Improvement entail?
Incorporating changes and improvements in equipment, procedures, and tasks
How is reliability achieved in operating machinery?
- Equipment is designed for the required operating conditions and performance
- Equipment is operated within design limits and according to specified operating procedures
- Required maintenance is carried out
What are some factors that can be used to measure the success of a maintenance program?
- reliability
- availability
- product quality
- production capacity
- cost
