and Associated Equipment

NVQ 2356-99 Level 3 in Electrotechnical Services Experienced Worker – Installing Instrumentation and Associated Equipment

The Installing Instrumentation and Associated Equipment NVQ 2356 Level 3 consists of seven units, 301 to 304 & 312 to 314, 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) needs to be covered only on one occasion and this is a three day practical assessment taken at an AM2 Centre anywhere in the UK.

Unit 304 – Maintain a Safe and Healthy Working Environment

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’ under key words and phrases. 

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

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

  • 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.

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 304 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’.
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, 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.

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.

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.

Unit 304 Performance Objectives

Safe system of work: In this unit, this refers to a system of work which will include procedures such as safe isolation, permits to work, wearing personal protective equipment, as appropriate, identified as being necessary during an assessment of risks. The system of work may take the form of a method statement.
Scope of work: In this unit, this may take the form of verbal and written specifications.
Site services: In this unit, these are services associated with the instruments and associated equipment, these could include, for example, water, gas services, oil, electricity, hydraulics and pneumatics.
Working conditions: In this unit, this refers to the working conditions which exist at that point in time when the installation is due to take place, but they could vary. It could be, for example, that the installation is to take place outside, in which case you may need to take account of the weather conditions. Or, they could include other (non-electrical) operatives who come onto the site to start their work – their subsequent activities may change the working conditions.
Working environment: In this unit, this refers to the different types of site, including hazardous areas, where the installation is due to take place. The working environment is something you would not be able to change. The type of site will determine whether the working environment affects the type of instrumentation and associated equipment to be installed.
