Remove components from electrical process plant and equipment

URN: COGPEM18
Business Sectors (Suites): Process Engineering Maintenance
Developed by: Cogent
Approved on: 27 Mar 2018

Overview

This standard is about your competence in removing electrical components. You will be required to identify, remove, check the condition, mark and store for further use. You will be following your organisation's safe working practices and working within the work permit procedures.

This standard deals with the following:
1 Remove components from electrical process plant and equipment

During this work you must take account of the relevant installation procedures and safe working practices AS THEY APPLY TO YOU.

Performance criteria

You must be able to:

P1 work safely at all times, complying with health and safety and other relevant regulations and guidelines including the requirements for isolating and locking off the electrical supply and checking for zero electrical supply to the work area   P2 establish, and where appropriate, mark component orientation for re-assembly P3 ensure that any stored energy or substances are released safely and correctly P4 remove the required components using approved tools and techniques P5 take suitable precautions to prevent damage to components, tools and equipment during removal P6 check the condition of the removed components and record those that will require replacing P7 label and store the removed components in an appropriate location P8 store or discard the removed components in accordance with approved procedures P9 maintain documentation in accordance with organisational requirements

Knowledge and Understanding

You need to know and understand:

K1 you must have a working knowledge and understanding of what your responsibilities are in respect of health, safety and environment. This should include the limits of your personal responsibility, your legal responsibility for your own health and safety and the health and safety of others K2 you must have a working knowledge of the relevant regulations and the safe working practices and procedures including the requirements for isolating and locking off the electrical supply and checking for zero electrical supply within your work area K3 you must have an appreciation of the engineering drawings and related specifications to which you will be expected to work, including: technical drawings (component, assembly, general arrangements, isometrics, 1st and 3rd angle projections), method statements and product worksheets, tolerances K4 you must have working knowledge of what the types of component removal methods and techniques, i.e. isolations and connections, are that have to be made, and which tools, equipment and methods can be used to remove specific components from specific products/assets K5 you must have an appreciation of how to assess and identify the condition of removed components K6 you must have working knowledge of how to label and store components for re-use including the marking systems for specific components and connections K7 you must have an appreciation of how to dispose of unwanted components and substances. This should include what substances could be released during the removal of components, which risks are associated with the release of substances, and where to access information on the environmental standards, including an appreciation on COSHH, SEPA and company procedures K8 you must have an appreciation of what your responsibilities are for ensuring the care and security of tools and equipment that you use K9 you must have an appreciation of your responsibilities with regard to the reporting lines and procedures in your working environment

Scope/range

Scope Performance

1 The level and extent of responsibility in the context of this standard, extends to working with a detailed specification, varying techniques and activities and applying appropriate methods to achieve the best possible result in the conditions applying. You will be accountable for the integrity of the work site and ensuring the work is recorded in a formal manner albeit you will be expected to refer to others. Authorisation for proceeding with the work will be given by authorised signatories within the Permit to Work system

2 The Equipment to be worked on will be operational assets and should include:
2.1. Rotating equipment and tools
2.2. Protection methods
2.3. Electrical distribution systems

3 The type of components to be removed may be robust or fragile. Robust components are those which are resistant to most forms of damage or disruption during their working lives

Fragile components are those which are easily disrupted or damaged. Damage or disruption could be due to physical, chemical or other forces (e.g. Electro-magnetic)
Typical robust components could be:
3.1. Components of power/lighting transmission
3.2. Motors/components of motors
3.3. Components of process control systems
3.4. Heat exchangers
3.5. Components of electrical back-up systems


Typical fragile components could be:
3.6. Components of electrical circuit protectors
3.7. Electrical meter devices
3.8. Circuit boards
3.9. Safety/protection devices
3.10. Components of electrical panels

4 Removal techniques or procedures to be followed
The components to be removed may require a sequential series of steps to complete the removal. The component may be difficult to access and may be surrounded by other fragile/valued components and may need specialised tooling requirements. Removal may involve more than 1 differing technologies and/or involve a significant number of fragile components

The specifications to which a candidate would be expected to work to could include:
4.1. Product worksheets
4.2. Technical drawings (components, assembly, general arrangement, isometrics)
4.3. Method statements
4.4. Maintenance schedules

5 The removal operations will be simple. Simple removal of components refers to situations where the component is quickly and easily removed from its position. Typical examples could include lifting out of plug-in components and undoing threaded fasteners to release the component

Scope Knowledge

The Knowledge and Understanding levels expressed indicate the minimum level of knowledge and understanding sufficient to perform your role in a manner that would normally be associated with the minimum acceptable performance of a competent person undertaking your role.

The expression “an appreciation” is intended to indicate a level of knowledge and understanding equating to:

1 An awareness of the existence, the scope and the background to the content covered by the knowledge and understanding statement
2 How and where to find further detail and information that you will need
3 Having obtained the information, you will be expected to check your interpretation and then to be able to apply it to your situation

The expression ”working knowledge and understanding” indicates you are able to:
4 Identify and apply relevant information, procedures and practices to your usual role in your expected working environments needing only occasional recourse to reference materials
5 Describe, in your own words, the principles underlying your working methods. This does not mean the ability to quote “Chapter and verse”. Rather you must know what supporting information is available, how and where to find it and from whom to seek further guidance and information confirm any additional required detail
6 Interpret and apply the information obtained to your role, your working practice and in your expected working environment
