ANSI standards are voluntary consensus standards, and are generally regarded
among the best practices where fall protection is concerned. Some states have
incorporated one or more of the ANSI standards by reference, meaning that they may be
enforced by some state or local agencies. Check with your State Department of Labor
for further details. ANSI standards are available for purchase through the e-standards
store at

Appendix A – EcoAnchor with Checkline Clear-Fall Requirements
When a pair of EchAnchors are used with the Checkline 4-User Temporary
Horizontal Lifeline System, the flexibility and movement of the anchors during a fall
event changes the performance of the Horizontal Lifeline (HLL) element when compared
to its typical performance when attached to rigid anchorages. When using the Checkline
THLL with EcoAnchors, refer to the Chekcline Instructions for the installation procedure,
but use the values below to evaluate Clear-Fall Requirements.
In order to properly demonstrate the feasibility of this system and to plan for the
Clear-Fall Requirements of this system, please review the following details:

*Dynamic Sag values include the distance that the EcoAnchors will potentially

In order to determine the actual Clear-Fall Distance you will need to plan for, use the
chart below. In the column that shows the length to which your HLL will be adjusted,
enter the
Actual Free-Fall Distance
your system will allow when installed and the
Height of the tallest worker
who will be using your system. To determine the total
Clear-Fall Required, add the five numbers in that column together.
