Are overhead power lines safe, especially considering concerns about EMFs and health?
2025-07-19Overhead power lines are an essential and generally safe component of modern electrical infrastructure, designed and constructed to stringent safety standards worldwide. Concerns about Electric and Magnetic Fields (EMFs) have been extensively researched globally for over 40 years. The overwhelming scientific consensus, as affirmed by organizations like the World Health Organization (WHO), is that there are no proven health effects below established exposure limits.
Our equipment and the methods we advocate for, such as tension stringing, are specifically designed to ensure maximum safety during construction and maintenance, minimizing risks to workers and the public. We prioritize equipment that helps maintain safe clearances and facilitates adherence to international safety guidelines. While EMFs are naturally present wherever electricity flows (including in homes and appliances), the fields from overhead lines diminish rapidly with distance. Utilities worldwide operate within strict guidelines to ensure public safety.
