NVQ 2356-99 Level 3 in Electrotechnical Services Experienced Worker – Electrical Machine Repair and Rewind

The Electrical Machine Repair and Rewind NVQ 2356 Level 3 consists of seven units, 326 to 332, and each unit needs to be completed over three separate occasions.

This can be any number of jobs / tasks and does not necessarily mean three separate jobs or three separate locations.

These three occasions can be done by observations / professional discussions by your assessor or witness statements / site diary created by yourself using evidence collected from jobs / tasks.

The additional Unit 399 (AM2 Practical Assessment) is NOT required for this NVQ.

Unit 326 – Ensure Safe Working Practices For Electrical Machine Repair and Rewind

This unit is for you if you are repairing an electrical machine as you will need to ensure the workplace is safe for working.

This unit is about ensuring that the workplace is safe for work to start through an assessment of the working environment where the work will take place. It is also about using safe working practices, including monitoring that the workplace continues to be safe and that the workplace is left in a tidy and safe condition on completion of the work.

You need to show that you possess the skills and knowledge to:

  • Assess the working conditions for health and safety purposes
  • Carry out safe working practices including use of mechanical handling equipment
  • Monitor that the workplace continues to be safe for work to continue, and
  • Store tools and equipment away safely after use.

Unit 332 – Maintain a Healthy and Safe Working Environment When Repairing or Rewinding Electrical Machines

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 learner 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 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
  • You take sensible action to put things right, including: reporting situations which pose a danger to people in the workplace and seeking advice.

You need to show 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.

To help with your understanding, the ‘Key Words and Phrases‘ section below gives more details about some of the words and phrases which have been used in this unit.

Unit 332 Key Words & 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 is 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.
Relevant people: These include: customers, clients, client representatives, chargehands, supervisors, other contractors, colleagues.
Working practices: This includes: activities, procedures, use of materials or equipment and working techniques used in carrying out your job.

Unit 332 Performance Objectives

You must ensure that: 

  1. You identify which workplace health and safety procedures are relevant to your working environment
  2. You identify evacuation procedures and emergency exits before work commences
  3. You review your working practices and your working environment for hazards which could cause serious harm
  4. You control those health and safety hazards within your capability and job responsibility limits
  5. You report those hazards which may present a high risk to the relevant persons responsible for health and safety in the workplace
  6. Your personal conduct around the workplace does not endanger the health and safety of yourself or other persons
  7. You follow the workplace policies and suppliers’ or manufacturers’ instructions for the safe use of tools, plant and equipment
