When it comes to high voltage (HV) installations and trenching, safety isn’t just a box to tick, it’s a non-negotiable priority. With the potential for serious injury, service disruption and costly delays, managing risk on site is critical to the successful delivery of any power infrastructure project.
At KNTC, safety is built into every step of our process. From planning through to execution, we follow rigorous procedures to protect our teams, the public and the integrity of the network.
HV installation: understanding the hazards
HV installations and trenching come with a unique set of challenges. Working near live systems, operating heavy machinery, and managing deep excavations all carry significant risk. Add to that changing ground conditions, the presence of existing utilities, and unpredictable weather, and the importance of proper safety measures becomes even clearer.
Key risks include:
- Electrical hazards from proximity to or contact with live equipment
- Collapse risk in unsupported or poorly managed excavations
- Striking buried services, which can cause serious injury or network outages
- Manual handling injuries and machinery-related accidents
- Environmental hazards, such as flooding or contamination
Building safety into every stage of HV installation
Minimising risk starts long before a spade hits the ground. At KNTC, we begin with thorough site surveys and utility searches, using up to date mapping and, where necessary, vacuum excavation to locate services safely.
Risk assessments and method statements (RAMS) are tailored to each project, and our teams are briefed clearly on site-specific hazards and safety procedures. Where HV work is involved, we adhere strictly to industry guidelines and DNO/IDNO protocols.
During trenching, we use approved shoring and support systems, safe access points, and constant supervision to avoid collapse. Trenches are securely fenced and signed to protect workers and the public. Live HV work is only carried out by fully qualified operatives, with appropriate permits, PPE, and lockout-tagout procedures in place.
By staying proactive, adaptable, and vigilant, we ensure that every KNTC site operates with the highest standards of care and professionalism. If you need a trusted partner for HV civil works and trenching, KNTC can help.
