Safe Isolation

  1. Martindale Meets Voltage Indicator Safety Standards

    On the left of the image white, large text reads "Voltage indicator safety standards". Beneath this in smaller, yellow text, it reads "Martindale VI-13800 Voltage Indicator". Martindale's logo is in the top-left of the image. On the right of the image  a Martindale VI-13800 Voltage Indicator is being used to prove a circuit. In May 2013, a new safety standard, BS EN 61243-3:2010, came into effect. It required voltage indicator manufacturers to incorporate a different method of limiting current in the event of cable damage. To ensure compliance with this revised British and European standard, which has been included in every subsequent edition of HSE’s GS38 Guidance Note, Martindale has updated their VI-13700/2 Two-Pole Voltage Indicator.

  2. Safe Isolation: Staying A.L.I.V.E

    It has been sixteen years since Michael Adamson, an experienced 26-year-old electrician, tragically died after cutting a cable marked “NOT IN USE”. The cable had been wired into a distribution board and was not safely isolated; Michael suffered a fatal electric shock. Over the years, leading bodies, such as the Electrical Safety Roundtable, have worked to develop procedures and protocols designed to prevent injuries and fatalities caused by a lack of safe isolation. Now, Martindale has developed an easy-to-follow and memorable safe isolation process: A.L.I.V.E.[1] Continue reading →
  3. What Are CAT Ratings?

    On the right of the image a DiLog CombiVolt Tester is being proved using a DiLog PU690 Proving Unit. The proving unit is hanging on the wall in a black fabric case with a clear, plastic window through which the PU690 can be seen and accessed. On the left of the image it reads 'What Are CAT Ratings?' in white and yellow block lettering. In summary, CAT ratings are overvoltage categories; they are safety ratings that indicate the types of electrical environments in which test and measurement instruments can be safely used. Understanding these categories is crucial to ensuring that you select the correct tool when working on an electrical installation.[1] Continue reading →
