Article 5
United Kingdom
In the case of loss of structural integrity for tailings dams, human lives shall be deemed to be threatened where water or slurry levels are at least 0,7 m above ground or where water or slurry velocities exceed 0,5 m/s.
The assessment of the potential for loss of life and danger to human health, shall comprise at least the following factors:
the size and properties of the facility including its design;
the quantity and quality including physical and chemical properties of the waste in the facility;
the topography of the facility site, including damping features;
the travel time of a potential flood-wave to areas where people are present;
the propagation velocity of the flood-wave;
the predicted water or slurry level;
the rising rate of water or slurry levels;
any relevant, site-specific factors that may influence the potential for loss- of- life or for danger to human health.
