EUSR Endorsed GS6 Avoidance of Danger from Overhead Services

Course details

The GS6 – Avoidance of Danger from Overhead Lines course provides essential safety training for individuals who plan, supervise, or carry out work near overhead electrical services. Aligned with HSE Guidance Note GS6 (Fourth Edition), the course focuses on recognising overhead line hazards, understanding legal duties, and implementing control measures to prevent contact with live power lines.

This training equips delegates with the skills to establish and apply a Safe System of Work (SSOW), promote best practices, and reduce the risk of serious injury or fatalities when working in environments where overhead lines are present.

Who Should Attend

This course is suitable for anyone involved in work near overhead power lines, including:

• Managers and supervisors
• Site safety teams
• Designers, including Temporary Works Coordinators (TWC) and Supervisors (TWS)
• Plant and machinery operators
• Construction, civil engineering, and agricultural personnel
• Scaffolders and access contractors
• Arborists and tree-cutting operatives
• Telecommunications and renewable energy staff

It is particularly recommended for personnel responsible for planning, supervising, or carrying out work near overhead lines where accidental contact could result in serious injury or fatality.
