HSE aims to reduce work-related death, injury and ill health.

For loop impedance, RCD or multifunction testers, the fuse will typically be 10A. The document provides advice and guidance on how to work safely and ensure the right equipment is used and maintained properly.

Risky business Vehicle safety on farms Kidsafe: The guidance has not fundamentally changed from the previous version. This document provides advice and guidance on how to achieve this. This standard, which came into full effect in Mayis the standard that all new two pole voltage indicators should comply with. A brief guide Electricity at work: The Electricity at Work Regulations require those in control of all or part of an electrical system to ensure it is safe to use and maintained in a safe condition.

A newly added paragraph touches on the importance or carrying out risk assessments, putting into place relevant safety measures and the use of appropriate PPE.

This website uses non-intrusive cookies to improve your user experience. A final change regarding test leads relates to the use of fused leads.

However, if those leads ga38 not rated to the same category as your gs338, you could be putting yourself at risk.

Firstly the Guidance Note has been amended to reflect relevant changes to the standard for two pole voltage indicators, BS EN This fourth edition includes current test equipment and references and links to further guidance have been updated. Clarification of the different installation categories BS EN CAT ratings is included in the guidance note as a reference and a visual guide is available to download at the end of this article.

Whenever there are changes made to legislation and best practice, questions are often raised regarding existing equipment and whether it can still be used. Related products Electrical safety and you: If you find you have leads or test equipment that no longer meet these requirements, jse have been damaged, it would be advisable to replace them to ensure your ongoing safety.

There are particular requirements for the use hsf non-contact devices in coalmines. GS38 Fourth edition Download gs83 free copy. Only devices which make contact with the conductor ie not proximity devices should be used for proving dead. For existing leads and equipment predating these standards, or manufactured to a different standard, GS38 states they must be maintained to prevent danger and should comply with the guidance probes and clips in paragraph 9 download the yse guidance note below.

A footnote has been added to clarify that live working is defined as any testing or fault finding on live systems. Throughout this section, revisions have been made to include the need for ongoing risk assessments to ensure safety is maintained as well as re-emphasis of the need for selecting the right CAT safety rating for the installation under test. This has changed in the fourth edition, emphasising the importance of using test leads and test equipment that is suitable for the category of the installation.

This has a new paragraph added regarding the use of non-contact detectors, or volt sticks: The Regulations permit few circumstances where it is acceptable for live working activities to be carried out on electrical equipment or systems, this includes electrical testing and fault finding. Such devices should be proved before and after use. Two key points have been added to the examples of common problems to look for: Setting the multimeter to the gw38 voltage range will lead to a false reading, but having it set to measure current or resistance can result in excessive current being drawn through the test probes, leads and multimeter.

There are several points highlighted here that should be considered closely when it comes to test equipment selection. This is an important safety issue as using equipment that is not correctly rated for the installation category can and has resulted in serious injury and death. Provided your existing equipment or leads meet either of the above there should be no need to replace anything until they need it. This includes electrical testing where dead tests are often as effective as live measurements.

If your leads break during testing it can be easy to swap them for another set hsse a multimeter or clamp meter. This should be done preferably on a voltage proving unit some devices have built-in hsd units or otherwise on a known live source of similar voltage to the circuit under test providing precautions are taken to prevent danger arising. When it comes to proving dead this has always been advised against by Electrical Safety First previously the Electrical Safety Council.

This section has some in-depth points regarding correct equipment selection.

Wherever possible, all work on electrical systems should be carried out with the system dead. Updates regarding the causes of accidents This section has been expanded on to include additional issues that have been raised since the previous publication: Trusted by Professionals Search: The fourth hsee of GS38 makes two important points regarding the hs38 of new equipment and the use of older equipment.

Hsse this page useful? Specific requirements for test leads In line with changes made to the standards that cover the manufacture of test leads, there are some specific requirements that leads should comply with added in the fourth edition: Precautions before testing This section has been expanded upon to recognise additional test processes covered by the guidance note.

While it has sg38 remained the same as the previous version, there are some key additions that could affect the way you test, or the equipment you are using. When it comes to buying new voltage detectors, you can be sure compliance with GS38 if the unit you are buying complies to BS EN For multimeters, fused leads should have a high-breaking capacity fuse hbc or hrc with a current rating that usually should not exceed mA.

An important point raised in the causes of accidents is the use of multimeters. Hs working practices Memorandum of guidance on the Electricity at Work Regulation. General changes The guidance note has been amended to reflect she wide range of people who ys38 on electrical systems, particularly those where electrical testing is not a primary activity such as gas installers and alarm installers.
