    Overhead Line Hazard Training

    Understanding the Risk Above the Ground

    Overhead power lines kill and injure workers every year. Unlike buried services, overhead conductors are visible, but that visibility creates complacency. The consequences of contact are immediate and almost always fatal. GS6 exists to give workers and managers the knowledge to recognise the hazard, plan their work correctly, and apply the control measures that prevent contact from occurring.

    Sygma's GS6 Overhead Power Lines course is delivered against the GS6 fourth edition and ENATS 43-8. It is available in two formats: a half-day classroom and assessment session for teams that need the theoretical grounding, and a full-day programme that adds a practical site element covering the use of the supa rule and the application of control measures in a real working environment.

    Both formats include a written assessment with a 70% pass mark. A verbal assessment is available as an alternative for delegates with dyslexia or other reading difficulties (contact Sygma at the time of booking to arrange this).

    Course Formats

    Choose the Format That Fits Your Needs

    Half-Day Awareness

    Classroom and written assessment only

    The half-day format covers the full classroom programme: legislation, GS6 fourth edition, voltage classifications, conductor behaviour, safe approach distances, and control measures. Delegates complete a written assessment before the session ends.

    ›Complete classroom programme covering GS6 and ENATS 43-8
    ›Written assessment at 70% pass mark
    ›Certificate of attendance on successful completion
    ›Suitable for teams needing theoretical grounding without site practical

    Full-Day with Practical

    Classroom, site practical, and written assessment

    The full-day format adds a practical site element to the classroom programme. Delegates use the supa rule to measure conductor heights in the field, identify tower and structure types, apply safe approach distances on site, and set up the control measures required before work can begin.

    ›Full classroom programme as above
    ›Practical site element including supa rule conductor height measurement
    ›Field identification of tower and structure types
    ›Applying control measures on a representative site
    ›Written assessment at 70% pass mark
    ›Certificate of attendance on successful completion

    Classroom Content

    What the Classroom Element Covers

    The classroom programme is common to both formats. It covers the legislative context, the technical content of GS6 and ENATS 43-8, and the practical control measures required before any work near overhead lines can take place.

    ›Legislation and guidance: Health and Safety at Work Act, CDM, Electricity at Work Regulations, and the role of GS6
    ›Consequences of overhead line contact: live incidents, statistics, and what happens in a contact event
    ›GS6 fourth edition: requirements, application, and what it means for your work activities
    ›ENATS 43-8: network specifications and what they tell you about the lines on your site
    ›Tower and structure types: wood poles, lattice towers, H-frames, and how to identify them
    ›Voltage classifications: extra-high, high, and low voltage overhead systems and what they look like
    ›Conductor sag: why conductors droop, what affects sag, and why this matters for approach distances
    ›Safe approach distances and the exclusion zone: the three-zone model and how to calculate required clearances
    ›Risk assessments for work near overhead lines: what they must contain and who carries them out
    ›Control measures: goal posts, crossbars, suspended loads restrictions, spotter roles, and danger notices
    ›Emergency procedures: what to do in a contact or near-miss incident, who to call, and how to manage casualties safely

    Site Practical (Full-Day Format)

    Applying the Theory on Site

    The full-day programme adds a practical element where delegates apply what they have learned in a real or representative outdoor environment. Sygma trainers use a flexible approach, adapting site activities to the location available.

    ›Reading and interpreting overhead line route drawings and DNO records
    ›Identifying tower and structure types in the field
    ›Estimating voltage from visual inspection of infrastructure
    ›Using the supa rule to take conductor height measurements
    ›Applying the three-zone model to a specific site scenario
    ›Setting out goal posts and crossbars at the correct clearance heights
    ›Completing a risk assessment for a representative work activity near overhead lines
    ›Discussion of spotter responsibilities and communication requirements on site

    Note on site requirements for the full-day format

    The full-day practical requires an outdoor area with a representative overhead line infrastructure within a reasonable distance of the training location. Sygma will confirm site suitability with you at the time of booking. If your site does not have suitable overhead infrastructure nearby, Sygma can advise on alternative arrangements.

    Assessment

    Written Assessment: 70% Pass Mark

    Both formats conclude with a written assessment. Delegates must achieve a minimum of 70% to receive the certificate of attendance. The assessment is completed at the end of the classroom programme, before the practical element on the full-day course.

    A verbal assessment is available as an alternative for delegates with dyslexia or other reading difficulties. This must be requested at the time of booking so that Sygma can make appropriate arrangements in advance.

    Common Questions

    Frequently Asked Questions

    Which format is right for my team?

    The half-day awareness format is suitable for teams that need the theoretical knowledge: understanding the hazard, the legislation, the control measures, and what the standards require. The full-day format is appropriate where delegates will have a direct role in applying control measures on site, operating plant near overhead lines, or conducting risk assessments. If you are unsure, contact Sygma and we will advise based on your team's roles and responsibilities.

    What is the supa rule and why is it relevant?

    The supa rule is a telescopic measuring pole used to determine the height of overhead conductors at a safe distance from the line. It allows the measured clearance height to be compared against the known sag curve data for that type of line, which in turn determines the maximum safe height for plant and equipment working in the vicinity. The supa rule is used as part of the risk assessment process under GS6 and is covered in the practical element of the full-day format.

    What does ENATS 43-8 cover?

    ENATS 43-8 is the Energy Networks Association technical specification that sets out the minimum clearance distances for overhead line construction in the UK. It provides the technical basis for the approach distances used in GS6. Understanding ENATS 43-8 allows delegates to understand why specific clearance distances are set as they are, rather than simply memorising numbers.

    Does passing this course give EUS recognition?

    No. The GS6 Overhead Power Lines course is an awareness and training programme delivered against the GS6 fourth edition. It does not form part of the EUSR (Energy & Utility Skills Register) qualification framework. Delegates who successfully complete the written assessment receive a certificate of attendance from Sygma.

    Can a verbal assessment be arranged?

    Yes. Sygma offers verbal assessment as an alternative to the written paper for delegates with dyslexia or other reading difficulties. This must be requested at the time of booking so that the trainer can prepare accordingly. The verbal assessment covers the same content and is conducted at the same pass mark threshold.

    Can you deliver this alongside other Sygma training on the same day?

    Yes, depending on the format. The half-day awareness programme can be combined with other half-day modules where your team has multiple training needs in the same visit. Contact Sygma to discuss combining GS6 awareness with other elements of your utility safety training programme.
