Flinders University School of Biological Science Electrical Safety Testing in 2004 or Doing More with Less
A brief summary to date Biology started electrical safety testing in 1999 Seaward Supernova and Pat1000 testers were supplied as standard testers WinPat software was chosen as the preferred management tool
Test types enter via barcode scanner
Tests originally available
How it worked…… A tester was used to perform the electrical safety test on an item. Test data were temporarily stored in the tester An item record was then manually added into the Winpats software running on a personal computer. Information keyed in at this stage covered item location, asset number, serial number, class of test, retest interval etc….. Actual data about the test was then uploaded onto the computer via a hardware link from the testers memory The two parts of data were then combined in the Winpats database (a Microsoft Access database) which was located on one of the Schools servers
So why change anything? The School was faced with the reality of regularly retesting in excess of 5,000 items and few resources to perform the task. This led to a review of our complete process.
Issues Identified Test were slow to perform – lots of buttons and keystrokes for each test Too much information was being kept about the test – all we needed to know was: did it pass or fail? Two data entry points for each test Data stored in the testing unit was susceptible to being deleted prior to being uploaded to the computer – this is a problem with multiple users of the Supernova tester Winpats software was perceived as not being user friendly
How can testing be improved? Perform pass or fail testing with a simple tester One data entry point for ALL required information – including retest management Easier data entry A more portable system that suits the layout of the building and lab areas
The new *TNT tester Test and Tag *Meeting AS/NZS 3760:2001 Industry Standards
Simpler lead testing
Simpler item testing
Simpler test menu structure X
How to handle the data entry? Use a web based system for single point data entry into a database located on a central server – Users need access to an active web browser Develop browser windows that will suit both portable data entry via a Pocket PC (with wireless network access) and standard notebook or desktop computers Provide an easy method to list retest due items
Pocket PC Application
How do I connect it? AC power needed Network connection needed
What no barcode reader…..
Must scan the right way up! Barcodes must be in good condition!
The Pocket PC will default to this page when Internet Explorer is opened An overview of data entry First logon to this web address Note……. You can test drive this software by going to the site above and using test for the username and test as the password. A sample barcode number of will allow you to evaluate the software. The test login will not allow you to save any changes made.
An overview of data entry The user logon screen Pocket PC (PDA) Logon Screen OR Standard Computer Browser Logon Screen
An individual who has completed the University training course in electrical safety testing is issued a username and password When a person logs on to the system, their name is automatically registered as the one who will be performing the electrical safety test – this eliminates the need to retype entries The logon screen also makes the database information more secure An overview of data entry Why a user logon screen?
An overview of data entry The Main Menu Screen For new items (or previously untested items) select this option and click Submit at the bottom of the screen To find details of a previously tested item by using its barcode number select this option, enter the barcode number in the box provided and click Submit To locate items that are due for retesting select this option and click Submit The Administration Screen allows those with admin rights to manage usernames, passwords and test locations - select this option and click Submit
An overview of data entry Adding a new item…. Select Add New Entry Then click Submit
An overview of data entry Adding a new item…. When all data is entered click Submit
An overview of data entry Adding a new item…. After clicking Submit you will be asked to confirm the updating of the database If any boxes remain incomplete you will see this error message
An overview of data entry How do I find items needing retest? Select Find EST Barcode from the main menu screen Then click Submit
An overview of data entry Finding a bar coded item….
An overview of data entry How do I find items needing retest? Select Other Search Options from the main menu screen Then click Submit
An overview of data entry How do I find items needing retest?
An overview of data entry What results will I be given?
An overview of data entry Updating the test….. When all data is entered click Submit
An overview of data entry Updating the test….. After clicking Submit you will be asked to confirm the updating of the database If any boxes remain incomplete you will see this error message
An overview of data entry Finding items…..
An overview of data entry Finding items by keyword…..
An overview of data entry Entering short term tests….. Use EST barcode numbers as you normally would in this box….. Select Short Term in the Retest box Please note that Short Term tested items will not appear in any of the retest due lists – they are ONLY one- off tests designed for items that are not permanently located within Biology (or Biology related) areas. From the Add New Entry item in the main opening menu:
Other ways to find items that need retesting Rapid retesting identification by the smart use of identifying labels
An overview continued New tested/retest labels….. The current use to labels Current test sticker show the date tested and person that performed the test (in this case number 4) (this label will be replaced - see next slide) University Asset number (only used on major equipment items) (this remains the same as previous) EST barcode label (this remains the same as previous)
An overview continued The new tested/retest label….. Colors and test dates shown are for demo only and may change Color indicate the year a retest is due – based on a 5 year cycle The following dates are valid for tests being performed in 2004 For 6 month or 1 year retest due items Will not be used till next year For 3 year retest due items Will not be used till next year For 5 year retest due items Cycle repeats starting 2010 Flinders University – Biology Electrical Safety Retest in Tested by: ____________ Flinders University – Biology Electrical Safety Retest in Tested by: ____________ Flinders University – Biology Electrical Safety Retest in Tested by: ____________ Flinders University – Biology Electrical Safety Retest in Tested by: ____________ Flinders University – Biology Electrical Safety Retest in Tested by: ____________ Flinders University – Biology Electrical Safety Retest in Tested by: ____________ The above labels are used on ALL tests performed White Orange Yellow Green Pink White – again….
Any of the above items that are likely to remain fixed in one location will only require a EST tested/retest label (ie no EST barcode) using a 5 year retest color Any of the above items that are used in higher risk areas should have EST barcodes and EST tested/retested labels attached of the corresponding color for the retest due date An overview continued Testing IEC cords, power boards and extension leads…..
An overview continued What if something fails the test? If an item fails electrical safety testing choose FAILED from the ReTest menu -Then enter the reason the item failed in the Comments box – YOU MUST COMPLETE THIS ENTRY IN ORDER TO PROCEED - After the Submit button is clicked an will be sent to with details of the item that failed - In addition, THE FAULTY ITEM MUST BE CLEARLY MARKED FAULTY WITH THE DO NOT USE – ELECTRICALLY UNSAFE LABEL PROVIDED
Electrical testing side issues! Or little useful tips……
Reminders…… When testing equipment with a physical ON/OFF switch, ensure the switch is ON before starting the test Check that the earthing clip from the TNT tester (or other tester model) is attached to a suitable metal part of the item being tested
Confused about what is double insulated? Sometimes an item with no earthing points is not marked as double insulated. Our technical staff can check it out and, if compliant, give it a sticker. If it has internally earthed components, they will add a test point, usually a stainless steel bolt near the mains inlet. Industry standard symbol for double insulated devices
ELECTRICAL APPLIANCES IN THIS CUPBOARD MUST BE SAFETY TESTED PRIOR TO USE What about items in the area that may not be used in the near future? Think about the use of these labels
Other test methods….
Check by first shorting the leads
Use yourself to check if the multimeter is reading correctly
Cant remember what pin is what?
What is this weird plug?
Andrew Daddow for his database and programming skills The many technical staff within Biology that have contributed to the design and testing of this solution Software products used include: –MySQL (open source – no cost) –PHP (open source – no cost) –SQLion (purchased software used for converting the old database information to SQL – Approx $70 Aust) Acknowledgments
