Compatibility:
When making connections with Metal Energy Absorber, eliminate all possibility of roll-out.
Roll-out occurs when interference between a hook and the attachment point causes the hook gate to
unintentionally open and release. All connections must be selected and deemed compatible with Metal
Energy Absorber by a Competent Person. All connector gates must be self-closing and self-locking, and
withstand minimum loads of 3,600 lbs. See the following for examples of compatible/incompatible
connections:
Correct Anchorage Positioning:
This chart details allowable working zones required
to reduce risk of swing falls and improper side loading.
ALWAYS adhere to information specified by chart.

For example, if the anchorage connector is 6’ from the leading
edge (Y), the working distance (X) is 8’ in each direction from
the perpendicular, which translates to a 53° working angle.
Swing Falls:
Prior to installation or use, make considerations for eliminating or minimizing all swing fall
hazards. Swing falls occur when the anchor is not directly above the location where a fall occurs. Always work
as close to in line with the anchor point as possible. Swing falls significantly increase the likelihood of serious
injury or death in the event of a fall.
As shown in following image, there are potential danger zones for swing falls when using a single HLL span.
Use multiple HLL spans to expand area of coverage.
