EAL - Using and interpreting engineering data and documentation

1. Explain what information sources are used for the data and documentation that they use

in their work activities

I will gather information documentation from my Line Manager or Project Engineer. I can also access

the company intranet for documentation - I can get information such as Employee Handbook, Health

and Safety information and Risk and Method statements. I can get data online from regulation

bodies and government websites. If I need information for a particular product I can search the

manufactures website or guidebook. There are COSHH documents and building guides in our

workshop. Technical manuals are kept in stores.

2. Explain how documents are obtained, and how to check that they are current and valid

Job cards and wiring diagrams are obtained from our project engineers that are overlooking that

particular job. I check they are current by the looking at the date, check what version of drawing

and if it is the latest and job number. I can check documents are up to date online and by the date

they were published.

3. Explain the basic principles of confidentiality (including what information should be

available and to whom)

1. At Powerstar all information that:-

a. is or has been acquired by you during, or in the course of your employment, or

has otherwise been acquired by you in confidence;

b. relates particularly to our business, or that of other persons or bodies with

whom we have dealings of any sort; and

c. has not been made public by, or with our

authority;

shall be confidential, and (save in the course of our business or as required by law) you

shall not at any time, whether before or after the termination of your employment,

disclose such information to any person without our prior written consent.

2. You are to exercise reasonable care to keep safe all documentary or other material

containing confidential information, and shall at the time of termination of your

employment with us, or at any other time upon demand, return to us any such material

in your possession.

3. You may not during or after the termination of your employment (without the limit)

use or disclose or allow to be used or disclosed (other than in the proper course of your

duties) any confidential information relating to us (or any Group company) or our (or

their) business, clients or customers. For these purposes confidential information

means any information which is commercially sensitive or which may not be readily

available to others engaged in a similar business to the Company or to the general

public, including but not limited to (add specific items).

Customer information strictly has to be kept confidential. Sensitive information could lead to risks

such as robbery or fraud.

Customer information strictly has to be kept confidential. Sensitive information could lead to risks such as robbery or fraud.

4. Describe the different ways/formats that data and documentation can be presented (such as such as drawings, job instructions product data sheets, manufacturers’ manuals, financial spreadsheets, production schedules, inspection and calibration requirements, customer information) At Powerstar we have the Projects Sheets which is basically a Job Card – it will tell us the customer information what type of product they want from us, the size, transformer information, install information etc. We have wire diagrams, circuit diagrams, drawings etc. We have these in paper form or we can gather this information from the computers. Schedules will be on white boards. We have information manuals for our tools. We have TV monitors in the meeting rooms which can be linked up to laptops and data can be shown for training. Inspection documents are often in tables, this is to help split up different steps of the job that is easily read and filled out once completed a step 5. Explain how to use other sources of information to support the data (such as electronic component pin configuration specifications, reference charts, standards, bend allowances required for material thickness, electrical conditions required for specific welding rods, mixing ratios for bonding and finishing materials, metal specifications and inspection requirements, health and safety documentation) So if for example we have been given a job card to complete a Powerstar Max unit I can use the Assembly guide to help me in the process. This is accessed by the company intranet or in a folder in the Max Department. Photos of step by step guides are also available. When it comes to terminate cables on the busbars we need to use the torque wrench. We can use a torque guide, for example it tells us torque all M5 device fixings 4Nm and torque all the m8 device fixings 11Nm. Health and safety guides and Risk Assessments are available to support our work. We also have graphs and bar chats on the company performance review board showing the company’s efficiency over the last 12 months. 6. Describe the importance of differentiating fact from opinion when reviewing data and documentation It is crucially important to differentiate between fact and opinion when reviewing any kind of data or documentation. Facts cannot be disputed, and provide the empirical evidence needed to draw direct conclusions from your work. Opinion is the basis with which thought and knowledge progresses. Opinion is an idea which can then be tested and proven or disproven. If we view facts as being Quantitative data - facts, figures, numbers etc. And opinion being Qualitative data - anecdotal, experience based etc. When given data from a Project Engineer and they say it needs doing this way you take the data as fact and follow it. 7. Describe the importance of analysing all available data and documentation before decisions are made I must always analyse all available data and documentations before decisions are made because sometimes you might make a decision which is completely wrong simply because you didn’t read the document all the way through. Also if I read the drawing properly I may find easier, faster and better ways to complete the job or parts. 8. Describe the different ways of storing and organising data and documentation to ensure easy access There are several ways to store and organise documents and data for easy access the more modern and common way of doing this is on a computer. You just need a small USB memory pen; you can

electrical side of things, this shows components needed such as switches and batteries it is simplified making it easier for the worker to read.

14. Explain what types of documentation are used and how they interrelate (such as production drawings, assembly drawings, circuit and wiring diagrams, block and schematic diagrams) When building a Virtue we use wiring diagrams, layout diagrams, and circuit diagrams. They all interrelate because most tasks will need consideration to all of these things, i.e. when working on a plate you would need to where the cables will be fed from and what else is in the vicinity that may present problems. Also job sheets for the Max units have an inspection and a final inspection, they both interrelate as the first inspection is smaller visual checks but the final one will be live working. 15. Explain the imperial and metric systems of measurement; tolerancing and fixed reference points Imperial and metric are both systems of measurement, metric being the more dominant in Europe and the UK, this consists of things like the millimetre, centimetre and meter, this is a more accurate and in my opinion and simpler way of measuring. Imperial measurements are in the inches and metrics are in the Millimetres, the chart below describes the convert. Metric Imperial 1 millimetre (mm) 0.03937 in 1 centimetre (cm) 10mm 0.03937 in 1 mere (m) 100cm 1.0936 yd 1 kilometre 1000 m 0.6214 mile Imperial Metric 1 inch (in) 2.54 cm 1 foot (Ft) - 12 inches 0.3048 m 1 yard (yd) - 3 feet 0.9144 m 1 mile - 1760 yd 1.6093 km 1 int nautical mile - 2025. 1.853 km Metric countries use simple multiples of metric units to size their products. Metric building products are sized in multiples of 10 cm. Metric beverage containers are in simple multiples of millilitres or litres (250, 500, 1, 1.5, etc.). In America (the last large non-metric country), building products are sized by USCS units of inches or feet. E.g. 2x4 [inch] stud* (lumber), and 2 x 4 [foot] lighting panel. Alcoholic beverages are sized in metric measures — but with standards approximating the previous USCS standards — the old 1/ gallon, 1/5 gallon (“a fifth”), and pint are replaced by 1.75 L (~1/2 gallon), 750 ml bottles (1/5 gallon), 375 ml (half bottle, or “pint”), and 187.5 ml (quarter bottle or “half-pint”). (Note: 1/2 and 1/5 gallons are close to their current metric sizes, but a metric “pint” became much smaller.) American automobile tires are in a worse state, with height (outer radius) in millimeters, width in percentage of height, and wheel rim diameter in integer inches. Also: - 1 inch is about 25 millimeters or 2.54 centimeters - A 3-foot measurement is almost exactly 1 meter

1 Kilogram is just over 2 pounds
1 pound is about 454 grams
For British visitors, 100 pounds = 7.14 stone
1 mile equals 1.6 Kilometers. 16. Describe the meaning of the different symbols and abbreviations found on the documents that they use (such as surface finish, electronic components, weld symbols, linear and geometric tolerances, pressure and flow characteristics) Examples of symbols: Diameter Width of square section Slope Taper Examples of abbreviations: ASSY - Assembly DRG - Drawing ENG - engineering QTY - Quantity R – Radius The guidelines we follow at Powerstar are:
