INFORMATION
Fall clearance
There must be sufficient clearance below the user to arrest a
fall before the user strikes the ground or another lower level
hazard. The clearance required is dependent on the following
factors:
–
Elevation of anchorage
–
Anchorage deflection
–
Lanyard length
–
Lanyard elongation on deceleration pull out (personal
energy absorber)
–
Operator height
–
Fall distance residual clearance
See AS/NZS 1891.4:2009 Section 7 for a detailed explanation.

System requirements
The worker must wear a full body harness when connected to
any fall arrest system including a personal energy absorber
compliant with Australian and New Zealand Standards
AS/NZS 1891.2:2001 and AS/NZS 1891.4:2009 limiting the
force on the anchor and operator to a maximum of 6kN.
Harness connectors must support at least 15kN. Non-
compatible connectors may unintentionally disengage (roll-
out). Carabiners supplied with proprietary systems must not
be removed or substituted with any other component.
Inspection and Maintenance
Inspection and recertification of fall arrest systems and
equipment is required at least every 12 months by competent
person in accordance with manufacturer’s specifications and
requirements of Australian and New Zealand Standard
AS/NZS1891.4:2009 Section (9).
