What Recent UK Strikes Reveal About the Lack of HSG47 Awareness on Site
When one looks closely at the incidents happening across UK construction and utilities, a pattern does become hard to ignore. Most strikes don't come from rare equipment faults or freak site conditions but from people who were never fully aligned with what EUSR HSG47 expects of a competent excavation team.
While cable strikes are a known fact in the UK, there are the same red flags that repeat themselves, and each one of them ties back into gaps in either planning, locating, or safe-digging practices that HSG47 sets out clearly.
Poor pre-excavation planning shows up first
HSG47 expects a process before any machine touches the ground: reviewing plans, identifying risks, confirming service positions, and questioning anything that doesn't make sense. Yet many recent strike reports show missing or outdated records, no follow-up questions, and no structured approach to checking the information.
When teams skip that early thinking, they enter the work believing the ground is exactly as the drawings show, even when the plans are inaccurate or incomplete.
Locating steps are rushed or incomplete
Another common thread running through recent incidents is how locator sweeps are conducted. Some teams only do one pass when a full multi-direction sweep is required. Others remain in a single mode without realising what they are losing. HSG47 is clear that locating should be methodical, variable and verified. If this doesn't happen, utilities are often misread or missed altogether.
In many cases, operators were familiar with CAT devices but hadn't been trained to interpret complex or distorted signals. That is the gap that becomes obvious when you compare the incident to what EUSR hsg47 requires.
Strikes expose weak communication between teams
A worrying number of incidents point to miscommunication rather than purely technical mistakes. Someone completes the sweep but doesn't explain uncertainties to the dig team. Markings are unclear or missing detail. Supervisors assume the locator results are accurate without checking them. HSG47 places heavy emphasis on communication for a reason: one unclear message on a busy site is all it takes for someone to dig in the wrong place.
Old habits no longer match modern utility layouts
So many of the UK strikes over the past year have occurred in areas of congested utilities or those that share the same trench. The signals operate differently in those locations, and old locating habits simply won't work. EUSR HSG47 is built around understanding such conditions and altering techniques to suit. Where teams cling to old habits, they miss the very clues that would have prevented the strike.
What This Really Tells Us
The message is simple. Strikes aren't isolated mistakes; they're indicative of root causes that key elements of safe-digging guidance were either never followed or not fully grasped. Many of these incidents simply wouldn't happen with regular training, structured planning and better communication.
