QUARRY operators are asking parents and teachers across Herefordshire to be on the alert this summer to deter youngsters from putting their lives at risk in search of adventure.

Unless tabs are kept on children, another summer-long headache is in store for quarry managers and other industry operators, including asphalt plants.

More than half of those who responded to a Quarry Products Association (QPA) survey said they were concerned about trespass by children and teenagers.

The county has 15 industry locations, of which six are active quarries.

Local QPA members are giving their backing to the QPA's annual "Play Safe, Stay Safe" campaign to bring the message home to youngsters via school visits and information and by publicising the problems to parents and teachers.

A video is available for use in schools via the QPA's website at www.qpa.org or from local operators.

Problems that most concern quarry managers are:

Swimming in often deep and dangerously cold quarry lakes.

Climbing on and vandalising quarry machinery.

Climbing on rock faces.

Digging caves in sand stockpiles that can collapse.

Cycling or motorcycling.
