Figure F.7 — Example of a tripod anchor device (in this example with working line and safety line rigged for rescue)F.3.3.4 After testing and/or a risk assessment, a single deadweight anchor may be used if it is judged that it would have sufficient mass and frictional resistance to the ground to provide an unquestionably reliable anchorage for both the working line and the safety line, and that there are appropriate attachment points for these anchor lines. Where the frictional resistance of one deadweight anchor is insufficient, two or more deadweight anchors may be used. Their frictional resistance should be confirmed as sufficient by testing and/or risk assessment.
