In a recent communication from the MPA Security Forum we have been informed about some mineral sites in Dartmoor National Park who suffered unwanted trespass during working hours by individuals participating in a straight-line marathon organised by a group named “STORROR”. There are various YouTube films online associated with them, and they have c.8 million followers.

The route took the participants right through two large mineral sites where operations were underway. The participants trespass without deviation regardless of obstacle or ownership. Both local police and the Dartmoor National Park Authority were advised of the incursion.

We would like to remind all Site Managers to review their risk assessments and procedures to ensure suitable precautions are in place to deter trespassers. These include fencing and signage at site boundaries and other significant hazards, minimising the risk to trespassers from hazards such as open water, access to heights and excavations, mobile plant and confined spaces.
