Assessment criteria - the learner can
...
Describe the specific safety precautions to be taken while carrying out the
assembly (including any specific legislation, regulations or codes of practice
relating to the activities, equipment or materials)

2
...
Describe the COSHH Regulations with regard to the substances used in
the assembly process

4
...
Describe the personal protective equipment and clothing to be worn
during the assembly activities

techniques; the purpose and function of the components (including
identification systems such as colour codes, manufacturer’s specification)

10
...
Explain how to identify and use the correct component handling
procedures (including relevant handling equipment)

12
...
Explain how the components are to be routed, aligned, adjusted and
positioned prior to securing, and the tools and equipment that are to be used

14
...
Describe the quality control procedures to be followed during the
assembly operations

16
...
Explain how to detect assembly defects (such as ineffective joining
techniques, component damage), and what to do to rectify them

18
...
Describe the importance of ensuring that all tools are used correctly and
within their permitted operating range

20
...
Describe the problems with the assembly operations, and the importance
of informing appropriate people of non-conformances

22
...
If equipment
is fitted with guards these must be used
...

Risk assessments are kept in a filing cabinet within the mechanical workshop

Q2: PPE can include items such as safety helmets, gloves, eye protection,
hazmat suits, high-visibility clothing, safety footwear, safety harnesses, ear
plugs, ear defenders and respiratory protective equipment
(RPE)
...
 Employers have duties concerning the provision and use of
personal protective equipment at work
...
You can prevent or reduce workers exposure to
hazardous substances by:

• finding out what the health hazards are

• deciding how to prevent harm to health

• providing control measures to reduce harm to health

• making sure they are used

• keeping all control measures in good working order






providing information, instruction and training for employees and
others

providing monitoring and health surveillance in appropriate cases

planning for emergencies
...
Another measure that can be taken is visual

inspect the components of the circuit ensuring that all appropriate
connections are made and there are no exposed wires
...
Other equipment such as insulating tool may also
improve health and safety conditions

Q5:

PPE can include items such as safety helmets, gloves, eye protection,
hazmat suits, high-visibility clothing, safety footwear, safety harnesses, ear
plugs, ear defenders and respiratory protective equipment (RPE)
...


Q6: I would summarise it in a few steps: familiarise yourself with the scale of
the drawings, Understand the basic symbols used in the engineering
drawings, Look for circled numbers, Identify specific abbreviations and finally
Work with colleagues
...
For
the third angle projection, the object is placed below and behind the viewing
planes meaning the plane of projection is between the observer and the
object
...
You will have an understanding of the product being assembled
and its application, and will know about the equipment, relevant components
and joining techniques, in adequate depth to provide a sound basis for
carrying out the activities to the required specification
...
Scientists, designers and
engineers have worked to invent and improve systems that impact lives
...
How the system will work is the
‘process’ and the ‘input’ is the part of the system that enables the process to
start happening
...
You will be required to check that specified
components are available and fit for purpose, to obtain all relevant and
current documentation, to obtain the tools and equipment required for the
assembly operations and to check that they are in a safe and usable
condition
...


Q11: Components should be handled by the edges when possible
...
Hand creams and lotions containing silicone
must not be used since they can cause solder ability and epoxy adhesion
problems
...


Q12: In carrying out the assembly operations, you will be required to work to
instructions in order to produce the required assembly
...
On completion of the
assembly activities, you will be expected to return all tools and equipment to
the correct location, and to leave the work area in a safe and tidy condition
...
There is a multitude of methods available to perform
accurate alignment, any of which can deliver the desired result
...
dial indicators,
parallel blocks, taper gauges, feeler gauges and a tape measure
...
You will be expected to work to instructions, with a
minimum of supervision, taking personal responsibility for your own actions

and for the quality and accuracy of the work that you carry out
...
You will be required to demonstrate safe working practices
throughout, and will understand the responsibility you owe to yourself and
others in the workplace
...


Q16: work safely at all times, complying with health and safety legislation,
regulations and other relevant guidelines

Plan the electrical assembly, wiring and testing activities before you start
them

Use appropriate sources to obtain the required specifications, circuit
diagrams, components, assembly and test

Obtain the correct tools and equipment for the assembly and test
operations, and check that they are in a safe and usable condition

Use the appropriate methods and techniques to assemble the components
in their correct positions

Secure the components ,using the specified connectors and securing
devices

wire and terminate cables to the appropriate connections on the
components

Use appropriate test methods and equipment to check that the completed
assembly is safe and meets all aspects of the specification

Deal promptly and effectively with problems within your control, and seek
help and guidance from the relevant people if you have problems that you
cannot resolve

leave the work area in a safe and tidy condition on completion of the
electrical assembly and testing activities

Q17: Quality control professionals typically classify quality defects into three
main categories: minor, major and critical
...


Early Stage Strategies for Reducing Defects Product Design: Poor product
design can obviously result in product defects
...
Inspection:
...
Quality
Control:
...
Not all
work equipment needs formal inspection to ensure safety and, in many
cases, a quick visual check before use will be sufficient
...
The need for inspection and inspection frequencies should
be determined through risk assessment
...

safe for use, maintained in a safe condition and inspected to ensure it is
correctly installed and does not subsequently deteriorate
...


Q20: Leaving a tool in or near an aircraft or its engine is not just an
inconvenience, but a safety risk
...


Tool control is essential to ensure that all aviation tools can be accounted for
at the end of the day
...


Q21: Assembly Line Issues

• Over (or Under) Producing Due to a Change in Demand
...


• Diminishing Returns on Lean Manufacturing Efforts
...


• Lack of Real-Time Information
...


• Unbalanced Station Workloads
...


• Lengthy Changeover Time
...


• Low Production Quality
...
You may find it helpful to suggest what you would like them to do
to resolve your problem
...


If they raise these concerns informally with you or as part of a performance
review, it is generally best to try to agree a solution then
