Fall Danger Zone

According to DGUV publication 201-056 (formerly BGI 5164), walkways that are less than 2 meters from the falling edge (where the outer edge of the structure is at least 3 meters above ground level) is considered the fall danger zone. ASR A2.1 are in agreement with this, stating: "Workplaces and accesses that are at least 2.0 m from the falling edge are outside the fall danger zone."

Working in a fall danger zone

Only those individuals are allowed to work closer than 2 meters to the precipitous edge, if they are accordingly secured from falling. As a rule, this is achieved through personal fall protection equipment (PPE) which is used by trained employees to attach themselves to locally-installed anchorage devices. The prescribed equipment always includes a safety harness and a suitable lanyard. If no anchorage points or lifeline systems have been permanently installed on the building structure, mobile anchorage devices can also be deployed on flat roof surfaces. These are generally weighed down with weights, e.g. concrete slabs or synthetic weights. However, if the danger zone needs to be accessed regularly, a collective protection measure is required, e.g. through installing a guardrail.
