Your gang has plans showing where the buried cables are on a site.
How far can you rely on the plans?
Choose one answer.
- AA. Only as a guide; cables still need tracing on site
- BB. Completely, as they show exactly where every cable is
- CC. Not at all, so there is no point getting them
- DD. Only if the plans are less than a year old
Show the answer and explanation
Answer: A
- A. Right: Right. HSE says plans give only an indication of where services are. Cables must be traced with a locator and marked before digging.
- B. Wrong: Wrong. Plans can be wrong or out of date, and cables move.
- C. Wrong: Wrong. Plans are a useful starting point. They just need checking on site.
- D. Wrong: Wrong. Even new plans only show roughly where services are.
Explanation
Service plans only show roughly where cables are. Trace and mark them with a locator, then confirm with hand-dug trial holes.
