Section 1 – Scheme information 1.1 Scope of the awards NVQs for the Electrotechnical Sector are work-based qualifications designed to reflect the roles and responsibilities of ‘occupation operatives’ within the sector. The Level 3 NVQ awards are based on a mandatory unit structure for the different occupational areas which facilitates opportunities for enhancement and transfer of competence from one electrotechnical occupation to another. The mandatory units cover those areas which have a common approach, such as safety and team working. The occupational units offer a choice that can be combined to meet the needs of organisations and candidates. 1.2 National Occupational Standards and Key/Core Skills The full National Occupational Standards and key skills mapping are included in this documentation. Centres should print whichever units are required by their candidates. 1.3 Restrictions on entry There are no restrictions on entry to this award, however, candidates should not register for this award if they hold or are registered with City & Guilds or another awarding body for a similar award at the same level. 1.4 Qualification structure The qualification structure requires candidates to complete mandatory units specific to each certificate.

Section 2 – Assessment requirements Assessment Guidance for Level 3 Electrotechnical NVQs: • Electrotechnical Services (Installation – Buildings & Structures; Installing

Instrumentation & Associated Equipment; Electrical Maintenance; Installing Highway Electrical Systems & Associated Equipment)

• Electrotechnical Panel Building • Electrical Machine Rewind & Repair Assessment must be carried out in accordance with the requirements of the Sector Skills Council for Building Services Engineering SummitSkills. The information which follows is developed from the ‘Assessment Strategy for Electrotechnical N/SVQs as amended June 2004. 2.1 Introduction SummitSkills as the Sector Skills Council for Building Services Engineering has developed an assessment strategy for the electrotechnical industry so that the requirements for the assessment of competence can be directly related to the national occupational standards which make up the above NVQs. The information below is intended to provide approved users of the NVQs with a consistent and standard approach to assessment. This includes the component parts of the assessment, recording systems and quality assurance. It also takes account of the differing backgrounds and experiences of those working in the sector and how this assessment strategy is to be applied. The SSC recognised that the level and amount of assessment required can vary according to the occupational role and experience of the candidate. In order to assist centres with the application of this three assessment categories have been identified

New Entrant Practising Operative Occupational Enhancement

Further details in respect of the assessment requirements for each are contained in the Appendix to this section. The assessment strategy sets out external quality control through the use of Practical Performance Assessment (PPA), assessment within the workplace, requirements for assessors and verifiers and guidance on implementation. In order to obtain an NVQ a candidate must satisfy the components parts of the assessment. The components of the Electrotechnical assessment are: 1 Practical Performance Assessment (PPA) in an independent assessment structure for

the key safety-critical aspects relevant to the identified national occupational standard being assessed which includes approved independent assessment of ‘Applied Knowledge’. (the only exception to this is where Practicing Operatives can provide suitable evidence)

2 The assessment of job knowledge using an externally set of guided written

assessments and/or assignments which are objectively marked. (This requirement would be met by achievement of a vocational qualification such as the technical certificate.)

3 Evidence from the workplace that demonstrates the candidate’s competence in the

non safety-critical aspects of the national occupational standards.

10

Practical Performance Assessment (PPA) and assessment of ‘Applied Knowledge’ will be carried out in an independent assessment structure, which will provide the conditions for these activities to take place. These activities will relate to the key safety-critical aspects of the relevant national occupational standards. SummitSkills has set criteria for the conditions for an independent assessment structure which must be approved by SummitSkils. Information on this can be obtained from SummitSkills Job Knowledge is assessed using an externally set of guided written assignments or assessments used to ensure objectively marked results and which must reflect the job knowledge requirements of the occupational standards being assessed. These assignments or assessments should relate to vocationally related taught qualifications, in part or whole, endorsed by SummitSkills. For all units performance must be assessed using evidence sourced from the workplace. The quality of evidence collected for those non safety-critical aspects must be sufficient, current and valid. Evidence from the workplace, including direct observation will demonstrate competence against the standards. Guidance for this is provided through Evidence Profiles (see below) which are available for each unit and which detail the scope and source. For the non safety critical units it will be necessary to provide evidence over three occasions. Key safety critical units require two such occasions and success in the PPA. Evidence and assessment planning must also demonstrate a candidate’s maturity in terms of competence and experience relevant to the level of national occupational standard being assessed, particularly for the key safety-critical aspects of the national occupational standards The totality of evidence will consist of evidence sourced from the workplace, plus evidence from an independent assessment structure for the key safety-critical aspects of the national occupational standards (PPA) and underpinning knowledge. 2.2 External quality control The SSC recognises that the industry cannot afford for candidates to make mistakes in key safety critical and technically critical aspects within the workplace. Similarly it is not always possible for candidates to have the opportunities to gain sufficiency and quality of evidence for these aspects. In order to ensure that the system produces candidates with valid, reliable and quality assured evidence of their competence the Sector Skills Council (SSC) requires all candidates performance and knowledge be assessed within the key safety critical aspects and where appropriate relevant technically critical aspects.

These aspects are identified below. The key safety critical aspects of the qualification are

• inspection testing and commissioning

• safe isolation

• aspects of health and safety including risk assessment

• diagnosing and correcting electrical faults The technically critical aspects of the qualification are

• termination of cables, conductors and cable carriers

• application and connection of electrotechnical wiring systems and equipment

• interpretation of technical specifications and diagrams/drawings Therefore to provide external quality control SummitSkills has developed the independent assessment structure, Practical Performance Assessment (PPA) to provide for this by means

11

of simulated conditions. This aspect of the assessment strategy is controlled and monitored by SummitSkills. All details of the specification and approval criteria must be obtained from SummitSkills.

The independent assessment structure will provide facilities for activities using tools and equipment which model those found in the real workplace. The structure will also facilitate assessment of the candidates’ ability to apply knowledge to the practical work (‘Applied Knowledge’) that they are being asked to do. This will most likely be by approved forms of questioning. Therefore, the independent assessor will be assessing both the candidate's skill and knowledge. The assessment undertaken through the PPA is an additional measure of the assessment within the units. Evidence of closely supervised experience of the candidate’s involvement with the identified key safety-critical aspects and technically–critical aspects of the National Occupational Standards in the workplace must pre-support their assessment in the PPA. 2.3 Evidence Specification As with all NVQs competent performance must be demonstrated consistently and supported by evidence from a variety of sources. To provide an audit trail to support this each unit has an Evidence Profile. Each profile sets out the performance objectives which must be met, the source of the evidence taken from the ‘Key Words and Phrases’ and the scope of the evidence, i.e. how many wiring systems. All performance objectives identified in the Evidence Profile for each unit must be assessed. The ‘Scope of Evidence’ defines the minimum number of items from the ‘Source of Evidence’. Subject to the performance evidence being assessed, typically in the form of observation, witness testimony, or products of work as detailed in the Assessment columns of the Evidence Profile it is recommended that three pieces of evidence should be provided. The Evidence Profile provides for this with three columns, assessment 3 will be evidence sourced from the workplace or for the safety critical features by Practical Performance Assessment (PPA), as indicated in the Evidence Profile. Where performance evidence is not available for the Sources not identified within the ‘Scope‘, alternative evidence must be provided which shows that the whole of the range has been assessed. This should be in the form of candidate reports, or written log supported by oral or written questioning. Performance evidence assessed by a PPA must be pre-supported by a workplace

‘Endorsement Visit’. The amount and level of the evidence will depend on the particular assessment category so it is important to relate this with the additional information provided in the Annex to this section. 2.4 A summary of the Electrotechnical assessment strategy: In summary, practical performance assessment (PPA) and assessment of ‘Applied Knowledge’ will be carried out in an independent assessment structure, which will provide the conditions for these activities to take place. These activities will all relate to key safety-critical aspects of the relevant national occupational standards. In addition, SummitSkills requires that job knowledge is assessed using an externally set of guided written assignments or assessments used to ensure objectively marked results and which must reflect the job knowledge requirements of the occupational standards being

12

assessed. These assignments or assessments could relate to vocationally related qualifications, in part or whole, approved by SummitSkills. The requirements to meet the outcomes of the Electrotechnical assessment strategy are: 1 Practical Performance Assessment (PPA) in an independent assessment structure for

the key safety-critical aspects relevant to the identified national occupational standard being assessed and independent assessment of ‘Applied Knowledge’ relevant to identified national occupational standards.

2 The assessment of job knowledge using an externally set of guided written

assessments and/or assignments which are objectively marked. 3 Evidence from the workplace that demonstrates the candidate’s competence in the

non safety-critical aspects of the national occupational standards.

In addition, Summitskills also requires that assessors and verifiers have

14

occupational experience, as explained below, regardless of which Electrotechnical NVQ/SVQ they are assessing or verifying. Both Assessors and Internal Verifiers must:

• possess a qualification relevant to the occupation and level of competence being assessed

• be at least 25 years old with a minimum of three years' experience as a qualified operative/ practitioner in the electrotechnical sector

• possess a current health and safety qualification; for example, IOSH Working Safely certificate or an approved equivalent.

External Verifiers must:

• have had relevant experience of occupational assessment. Additionally SummitSkills recommends assessors and verifier also have the following:

• a thorough understanding of the national occupational standards for electrotechnical qualifications.

• knowledge of current practice and emerging issues in the qualification area

• experience and a working knowledge of the operation and assessment processes

specifically for Electrotechnical NVQs/SVQs. 2.7 Use of the national occupational standards It is the responsibility of assessment centres to ensure that all assessors are using currently accredited national occupational standards

All candidates being assessed should understand the national occupational standards to which they are being assessed in terms of the relationship with the qualification, relevant grading structures, technical competence and job roles/responsibilities Where assessors or verifiers believe that the national occupational standards could be reviewed to make them easier to understand or easier to assist in the assessment process, they have a responsibility to contact SummitSkills and suggest the change in wording. 2.8 Access to assessment There are no entry qualifications or age limits required for these awards unless this is a legal requirement of the process of the environment. Assessment is open to any candidate who has the potential to reach the standards laid down for this qualification. Aids or appliances which are designed to alleviate disability may be used during assessment providing they do not compromise the standard required. 2.9 Further guidance Further guidance to general procedures for the assessment of NVQs and sample recording forms is found in the N/SVQ Centre Guide (stock reference EN-11-0001)

Appendix 1 Level 3 National Occupational Standards assessment routes The component parts of the assessment strategy must be applied to each assessment route accordingly. 1 ASSESSMENT ROUTE: New Entrant A New Entrant is a NVQ/SVQ candidate who has undertaken or is undertaking a learning and assessment programme with no experience in the Electrotechnical Industry. Therefore evidence of their competence against the relevant National Occupational Standards (NOS) must be demonstrated using the listed assessment instruments:

1. Evidence sourced from the workplace, including direct observation as relevant, that demonstrates the candidate’s competence in non safety–critical, key safety-critical and technically-critically aspects of the relevant NOS

2. Practical Performance Assessment in an “Independent Assessment Structure” (See

above) of the key safety-critical aspects of the NOS and approved independent assessment of “Applied Knowledge”

3. The assessment of job knowledge using SummitSkills approved externally set guided

written assessments and assignments which are objectively marked.

2. ASSESSMENT ROUTE: Practising Operatives Practising Operatives are individuals who are working in the industry, and although competent have no formal recognition of their occupational competence. Evidence of their competence against the relevant National Occupational Standards can be demonstrated using, as appropriate, the listed assessment instruments and/or formal evidence of skill/knowledge:

1 Evidence sourced from the workplace, including direct observation as relevant, that demonstrates the candidate’s competence in non safety-critical, key safety-critical and as appropriate, technically-critically aspects of the relevant NOS. .

2 Practical Performance Assessment in an “Independent Assessment Structure” of the key safety-critical and, as appropriate, technically-critical aspects of the relevant NOS only where this cannot be demonstrated using evidence sourced from the workplace .

3 Evidence of qualifications, which reflect the job knowledge requirements of the relevant NOS and/or the assessment of job knowledge. This should include examples of relevant qualifications such as the IEE Wiring Regulations. NB Evidence of competence in the safety-critical and technically-critical aspects of the NOS sourced from the workplace must not be more than 24 months old.

3 ASSESSMENT ROUTE: Occupation Enhancement This assessment route is for individuals who have been in an occupational role such as electrotechnical operatives on oil rigs or in the armed forces and are seeking to obtain an electrotechnical NVQ as their occupational role could not provide the opportunities to acquire

16

sufficiency and quality of evidence for all the key safety-critical and technically-critical aspects of the relevant NOS. In these circumstances enhanced assessment must be undertaken to demonstrate their competency meets the requirements of the relevant NOS:

1 Evidence sourced from the workplace, including direct observation as relevant, that demonstrates the candidate’s competence in non safety–critical, key safety-critical and technically-critical aspects of the relevant NOS.

2 Practical Performance Assessment in an “Independent Assessment Structure” (above) of the key safety-critical and technically critical aspects of the relevant NOS which cannot be demonstrated using evidence from the workplace and the independent assessment of “Applied Knowledge”

3 Evidence of qualifications, approved by SummitSkills, which reflect the job knowledge

requirements of the relevant NOS and/or the assessment of job knowledge.

Appendix 2 Assessor Guidance This part of the guide has been introduced to enable assessors to have a clear indication of the evidence requirements of the Level 3 NVQ awards. The first section of the guide includes materials that were first produced as part of the awarding body guidance when the award was first accredited with QCA. Since this time the Sector Skills Council (SSC) SummitSkills has revised the assessment strategy that defines three specific routes for the assessment of skilled operatives. These routes are the new entrants (someone who has never worked in the industry before, as an example an apprentice), the practising operative (for example those working in the industry today but who do not have current recognition of their skills) and occupational enhancement (as example some one leaving the military). The guide explains in detail the assessment requirements for each of these routes. In producing this guide the awarding body has taken into account the advantages offered by digital assessment techniques, such as digital cameras, digital recorders, PDAs and digital pens along with traditional paper assessment. In doing so it has also provided guidance on how holistic assessment methods can reduce assessment requirements in portfolio production. In addition guidance is produced that confirms that assessment planning is a mandatory requirement for all awards and completed by all assessors. Evidence of which must be produced for both IV and EV procedures.

Initial assessment and assessment planning Initial assessment It is good practice for all candidates to receive an initial assessment at the very start of their NVQ. The results of the initial assessment can be used to identify the correct point at which a candidate starts the assessment. Subsequently, the results of initial assessments should also be used to inform the overall training and assessment plan for each individual candidate. Assessment Planning Following initial assessment the candidate should be provided with an individual assessment plan. Every NVQ portfolio should reflect the individual candidate’s 'unique' opportunities to collect and present appropriate evidence. This varied and individual package of evidence is what the assessor can then use to form the basis of an assessment decision. An assessment centre should show how it currently demonstrates that candidates receive an initial assessment prior to starting the qualification. The information below relates to the three routes, it offers tabular assessment guidance for each unit detailing both keywords and performance objectives. These were previously provided with the introduction to the Level 3 qualification along with copies of the NOS. The evidence exemplar for the one of the units, is provided, this details the type of evidence that could be provided and how they relate to both keywords and performance. Guidance in terms of knowledge evidence is also detailed within this introduction.

18

Evidence Requirements The New Entrant For the purposes of this guidance it should be noted that new entrants to the industry are not just young apprentices they may also include adults who are new to the industry and therefore subject to the same assessment requirements, as they are both new to the electro-technical industry and have no previous experience to offer as evidence. The evidence requirements for the new entrant will be derived primarily from the use of observation and evidence sourced from the work place. Questioning of candidates completed by assessors will support the evidence gained from workplace. When carrying out direct observation in the workplace the assessors should document the visits by the use of photographic evidence from the workplace. In order to demonstrate consistent competent performance a minimum of three different evidence examples will be required. The awarding body has made recommendations that the observation should be used to ensure that candidates are ready and capable of assessment under the controlled conditions of the PPA test. The knowledge assessment requirements of the new entrant will be satisfied by using approved externally set guided written assessment such as the 2330 certificate in electro technical technology, as well as pertinent supplementary questioning of evidence sourced from the workplace. The Practising Operative A practising operative defines individuals who are working in the industry and although competent have no formal recognition of their occupational competence. The candidate is required to produce evidence a minimum of three pieces of evidence within each unit to demonstrate competence against the all units required for the award. There is no specific requirement for the candidate to be assessed on site by observation, however an assessor may wish to use evidence by observation in certain employment circumstances e.g. self employed. In addition the practising operative is not required to undertake the PPA test provided all acceptable evidence submitted for assessment is less than 2 years old. It is expected that assessment of all written materials will be validated by questioning of the candidate, and those employers or clients for whom the candidate has worked or is working. With reference to job knowledge, the candidate would be expected to provide evidence of qualifications which reflect the requirements of the job knowledge of the qualification and in addition satisfy the assessor of their current understanding of technology and working practice, this may require the assessor to carry out supplementary questioning. The Enhancement route The candidate following the enhancement route is one who would already be able to generate evidence against his/her existing experience in the industry and so is more likely to be able use evidence from the mandatory units from previous experience and so only need to generate evidence from the optional units remaining from the new set of units required for enhancement. This will normally mean that they would be subject to the same requirements for assessment as the new entrant.

Assessment principles This section is intended to set out how the various forms of evidence should be used within the assessment of the level 3 NVQ (2356). A format has been produced which sets out these principles and provides an audit trial for candidates, assessors and verifiers. An evidence profile has been produced for each unit. An example of this grid is noted for unit 302 for each route.

19

Performance objectives All performance objectives must be achieved. The grid defines the amount of evidence and scope of evidence required. This would include evidence sourced by the use of observation, questioning and the use of product evidence accordingly. Performance evidence The scope and source of evidence of performance are indicated in the grid of the award, defined by the tables following this introduction, they are defined by the scope of the unit in terms of how many of a particular unit are required. Knowledge evidence Knowledge evidence will be provided by the primary use of current and past certification of relevant awards. Observation It is recommended that when observing candidates in the workplace the holistic assessment process should be used, gathering evidence for several units as appropriate will link relevant units together. When completing assessment in the workplace the assessor should also use photographic evidence of the candidate completing the observed work. At the same time assessment should also include questioning of the candidate which may include supplementary job knowledge. For the avoidance of doubt, observation on site means on observation of competent performance, not attendance to observe a candidate working badly. For new entrants and those following the enhancement route there would be a single observation in the workplace completed prior to the PPA test. Observation of practising operatives may be used to verify performance evidence provided by the candidate. Oral and Supplementary questioning Oral questioning of the candidates will be used to fill gaps in the assessment process. The use of oral questioning and supplementary questioning would not be sufficient to complete the assessment of a unit. The use of digital recording of the questions is recommended as this would add to the validity of the assessment process. When it is not possible to observe a candidates work then it is a requirement that the outstanding performance outcomes are covered by assessment using supplementary questioning. Product evidence Product evidence such as drawings, distribution board charts, specifications, evidence may be used to confirm the assessment requirement within the performance requirements of the awards. Witness testimony The use of witness testimony is a valid form of assessment within the level 3 awards. The assessment system used shall provide a method of checking who the witness is for the candidate. It shall be possible for the assessor to contact the witness to confirm the work and competence of the candidate. PPA Success in the PPA test is a mandatory requirement for the award of the NVQ. However there can be exemption for practicing operatives subject to the assessor confirming the candidates meet the criteria under that route.

UNIT 304 (NET Unit 81): Maintain a healthy and safe working environment

UNIT OVERVIEW This unit is for: you whilst at work. The Health and Safety at Work Act, 1974, seeks to secure the health, safety and welfare of people whilst they work and protect other people against risks to health or safety arising from the activity of people at work.

Read ‘important note’ following overleaf:

This unit is about: maintaining a healthy and safe working environment


• ensure that your own actions do not create any health and safety risks • not ignore hazards with significant risk in your workplace, • take sensible action to put things right


39


KEY WORDS AND PHRASES The Health and Safety Executive (HSE) is the body appointed to support and enforce health and safety law. They have defined two important concepts as follows: Hazard ‘a hazard is something with potential to cause harm’ Risk ‘a risk is the likelihood of the hazard's potential being realised’ Emergencies this includes: fire, explosions, toxic atmosphere, electrical

shocks Working conditions: This refers, to the working conditions which exist at that

point in time when the work is due to take place, but which could vary. It could be, for example, that the work is to take place outside, in which case you may need to take account of the weather conditions. Or, perhaps other (non-electrical) contractors come onto the site to start their work - their subsequent activities may cause the site to become hazardous.

Working environment: This refers to different types of the worksite where the

installation is to take place. These include: agricultural, industrial, commercial sites, or confined spaces or working near other machinery. The working environment is something you would not be able to change.

Relevant people: These include: customers, clients, client representatives,

charge-hands, supervisors, other contractors, colleagues. Working practices: This includes: activities, procedures, use of materials or

equipment and working techniques used in carrying out your job.

Important Note: According to the Health and Safety at Work Act: Employers must safeguard so far as is reasonably practicable, the health, safety and welfare at work of all the people who work for them and ‘other persons’. This applies in particular to the provision and maintenance of safe plant and systems of work, and covers all machinery, equipment and substances used. Employees also have a duty under the Act to take reasonable care to avoid harm to themselves or to others by their working practices, and to co-operate with employers and others in meeting statutory requirements. The Act also requires employees not to interfere with or misuse anything provided to protect their health, safety or welfare in compliance with the Act.

40


There is an array of health and safety regulations and codes of practice which affect people at work. There are regulations for those who, for example, work with electricity, or work on construction projects, as well as regulations covering noise at work, manual handling, working with VDUs, or dealing with substances hazardous to health, etc. The specific requirements for all or any of these can be obtained from HSE local offices. The phrase ‘the legal responsibilities for health and safety as defined by any specific legislation covering your job role’ is intended to relate to those specific pieces of legislation important to your workplace and/or activities which you should be able to find out about.

The Health and Safety at Work Act 1974 is the main piece of legislation under which nearly all the other regulations are made. It is for this reason that only this piece of legislation is specifically referred to in this Unit.

41

UNIT 325 (NET Unit 81a): Maintain a healthy and safe working environment when building panels UNIT OVERVIEW This unit is for:

a person carrying out activities at work –regardless of where that work might be. The scope of the Health and Safety at Work Act 1974 covers ‘all persons’ whether employers, employees, self-employed, contractors, etc. Amongst other things the Act seeks do is to secure the health, safety and welfare of people whilst they work and protect other people against risks to health or safety arising from the activity of people at work. This unit does not require the candidate to undertake a full risk assessment, it is about having an appreciation of significant risks in the workplace and knowing how to identify them and deal with them. It is important to note the following that according to the Health and Safety at Work Act:

Employers must safeguard so far as is reasonably practicable, the health, safety and welfare at work of all the people who work for them and ‘other persons’. This applies in particular to the provision and maintenance of safe plant and systems of work, and covers all machinery, equipment and substances used. People at work also have a duty under the Act to take reasonable care to avoid harm to themselves or to others by their working practices, and to co-operate with employers and others in meeting statutory requirements. The Act also requires employees not to interfere with or misuse anything provided to protect their health, safety or welfare in compliance with the Act.

This unit is about:

is about having an appreciation of hazards which may cause serious harm in the workplace and knowing how to deal with them. It describes the competences required to ensure that: - your own actions do not create any health and safety risks, - you do not ignore hazards with significant risk in your workplace, and - you take sensible action to put things right, including: reporting situations which

pose a danger to people in the workplace and seeking advice


that you understand the health and safety requirements in the workplace, and that you check your own work activities and work area for any hazards which may harm you or others. You should be able to identify those risks you can safely deal with yourself, and those which you must report to the ‘responsible’ person for attention.

130

UNIT 325 (NET Unit 81a): Maintain a healthy and safe working environment when building panels KEY WORDS AND PHRASES

The Health and Safety Executive (HSE) is the body appointed to support and enforce health and safety law. They have defined two important concepts as follows: Hazard ‘a hazard is something with potential to cause harm’. Risk ‘a risk is the likelihood of the hazard's potential being realised’. Almost anything may be a hazard, but may or may not become a risk. For example:

1. A trailing electric cable from a piece of equipment is a hazard. If it is trailing across a passageway there is a high risk of someone tripping over it, but if it lies along a wall out of the way, the risk is much less.

2. Toxic or flammable chemicals stored in a building are a hazard, and by their nature may present a high risk. However, if they are kept in a properly designed secure store, and handled by properly trained and equipped people, the risk is much less than if they are left about in a busy workshop for anyone to use - or misuse.

3. A failed light bulb is a hazard. If it is just one bulb out of many in a room it presents very little risk, but if it is the only light on a stairwell, it is a very high risk. Changing the bulb may be a high risk, if it high up, or if the power has been left on, or low risk if it is in a table lamp which has been unplugged.

4. A box of heavy material is a hazard. It presents a higher risk to someone who lifts it manually than if a mechanical handling device is properly used.

Emergencies In this unit this includes: fire, explosions, toxic atmosphere, electrical shocks

Working conditions: In this unit this refers to the working conditions which exist

at that point in time when the panel building takes place. One example may be the physical dimensions of the panel being built may affect working practices.

Working environment: In this unit this refers to the work area where the panel

building is to take place and this may be affected by other associated or allied trades, for example, paint spraying, sheet metal work, etc.

UNIT 332 (NET Unit 81d): Maintain a healthy and safe working environment when repairing or rewinding electrical machines UNIT OVERVIEW This unit is for:

a person carrying out activities at work –regardless of where that work might be. The scope of the Health and Safety at Work Act 1974 covers ‘all persons’ whether employers, employees, self-employed, contractors, etc. Amongst other things the Act seeks do is to secure the health, safety and welfare of people whilst they work and protect other people against risks to health or safety arising from the activity of people at work. This unit does not require the candidate to undertake a full risk assessment, it is about having an appreciation of significant risks in the workplace and knowing how to identify them and deal with them. It is important to note the following that according to the Health and Safety at Work Act:

Employers must safeguard so far as is reasonably practicable, the health, safety and welfare at work of all the people who work for them and ‘other persons’. This applies in particular to the provision and maintenance of safe plant and systems of work, and covers all machinery, equipment and substances used. People at work also have a duty under the Act to take reasonable care to avoid harm to themselves or to others by their working practices, and to co-operate with employers and others in meeting statutory requirements. The Act also requires employees not to interfere with or misuse anything provided to protect their health, safety or welfare in compliance with the Act.

This unit is about:

is about having an appreciation of hazards which may cause serious harm in the workplace and knowing how to deal with them. It describes the competences required to ensure that: - your own actions do not create any health and safety risks, - you do not ignore hazards with significant risk in your workplace, and - you take sensible action to put things right, including: reporting situations which

pose a danger to people in the workplace and seeking advice


that you understand the health and safety requirements in the workplace, and that you check your own work activities and work area for any hazards which may harm you or others. You should be able to identify those risks you can safely deal with yourself, and those which you must report to the ‘responsible’ person for attention.


160

UNIT 332 (NET Unit 81d): Maintain a healthy and safe working environment when repairing or rewinding electrical machines Key Words and Phrases The Health and Safety Executive (HSE) is the body appointed to support and enforce health and safety law. They have defined two important concepts as follows: Hazard ‘a hazard is something with potential to cause harm’. Risk ‘a risk is the likelihood of the hazard's potential being realised’. Almost anything may be a hazard, but may or may not become a risk. For example:

1. A trailing electric cable from a piece of equipment is a hazard. If it is trailing across a passageway there is a high risk of someone tripping over it, but if it lies along a wall out of the way, the risk is much less.

2. Toxic or flammable chemicals stored in a building are a hazard, and by their nature may present a high risk. However, if they are kept in a properly designed secure store, and handled by properly trained and equipped people, the risk is much less than if they are left about in a busy workshop for anyone to use - or misuse.

3. A failed light bulb is a hazard. If it is just one bulb out of many in a room it presents very little risk, but if it is the only light on a stairwell, it is a very high risk. Changing the bulb may be a high risk, if it high up, or if the power has been left on, or low risk if it is in a table lamp which has been unplugged.

4. A box of heavy material is a hazard. It presents a higher risk to someone who lifts it manually than if a mechanical handling device is properly used.

Emergencies In this unit this includes: fire, explosions, toxic atmosphere, electrical shocks

Working conditions: In this unit this refers to the working conditions which exist

at that point in time when the electrical machine repair takes place. One example may be the physical dimensions of the electrical machine being repaired may affect working practices.

Working environment: In this unit, this refers to the work area where the electrical

machine repair is to take place and this may be affected by other associated or allied trades for example paint spraying, sheet metal work, etc.
