Experts have sounded a warning after mindless trespassers broke into a Derbyshire quarry and scaled a massive chimney.
The intruders breached security at Lafarge’s quarry in Hope and climbed the 100-metre tall chimney – then took pictures for a website.
Nigel Jackson, chief executive of the Mineral Products Association (MPA), blasted the life-threatening “cheap thrill”.
He said: “It’s complete madness.”
The shock news emerged this week as the MPA launched a summer drive to highlight the tragic hazards of trespassing into quarries with hidden, life-threatening dangers including ice-cold lakes, steep cliffs, falling rocks and quicksand pools.
The campaign is backed by Tracey Walker whose 15-year-old son Ryan drowned while swimming in abandoned Far Hill Quarry, locally known as the Blue Lagoon, near Ashover, three years ago.
Mrs Walker, of Clay Cross, said: “It was a lovely, hot, sunny day – May 31, 2009 – and Ryan and some friends had decided to go to the Blue Lagoon.
“Later, I heard fire engines and helicopters but didn’t think anything of it.
“Then we got a phone call to say Ryan had gone underwater and he’d not come back up.”
Mrs Walker, who has called for more safety measures at quarries, described Ryan as a “fun-loving, popular and outgoing lad with a cheeky smile”.
Over the summer, the MPA will visit schools to highlight the campaign, which has a group, called Stay Safe... Stay Out Of Quarries, on Facebook.
