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:
Horizontal Peak Loads:
HLL Span: 1 User 2 Users 3 Users 4 Users
30 feet – 75 feet 900 lbs 1,100 lbs 1,350 lbs 1,550 lbs
75 feet – 100 feet 1,300 lbs 1,550 lbs 1,900 lbs 2,200 lbs
Minimum Clear-Fall Distance:
HLL Span: 0’-15’ 16’-30’ 31’-50’ 51’-75’ 76’-100’
Free-Fall Distance 6’ 6’ 6’ 6’ 6’
Height of tallest worker 6’ 6’ 6’ 6’ 6’
Deceleration Distance 3.5’ 3.5’ 3.5’ 3.5’ 3.5’
*Dynamic Sag 4’ 7’ 10’ 11’ 13’
Safety Factor 2’ 2’ 2’ 2’ 2’
Total Clear-Fall: 22’ 25’ 28’ 29’ 31’
*Dynamic Sag values include the distance that the EcoAnchors will
potentially slide in a fall event.
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.
Clear-Fall Worksheet:
HLL Span: 0’-15’ 16’-30’ 31’-50’ 51’-75’ 76’-100’
Actual Free-Fall Distance:
Height of tallest worker:
Deceleration Distance: 3.5’ 3.5’ 3.5’ 3.5’ 3.5’
Dynamic Sag: 4’ 7’ 10’ 11’ 13’
Safety Factor: 2’ 2’ 2’ 2’ 2’
Total Clear-Fall Required:
Warning: If the Clear-Fall Requirements in the worksheet above can
not be met at your work location, you will need to increase the set
back distance of the EcoAnchor/Checkline System or look for an
alternative system. Failure to provide adequate Clear-Fall Distance
may result in serious injury or death.
Appendix B – EcoAnchor with PSR Clear-Fall Requirements
When a pair of EchAnchors are used with the PSR 2-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 PSR THLL with EcoAnchors, refer
to the PSR 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:
Horizontal Peak Loads:
HLL Span: 2 Users
11 feet – 30 feet 2,787 lbs
31 feet – 60 feet 2,940 lbs
Minimum Clear-Fall Distance:
HLL Span: 11’-20’ 21’-30’ 31’-40’ 41’-50’ 51’-60’
Free-Fall Distance 6’ 6’ 6’ 6’ 6’
Height of tallest worker 6’ 6’ 6’ 6’ 6’
Deceleration Distance 3.5’ 3.5’ 3.5’ 3.5’ 3.5’
*Dynamic Sag 6’ 6’ 9’ 10’ 10’
Safety Factor 2’ 2’ 2’ 2’ 2’
Total Clear-Fall: 24’ 24’ 27’ 28’ 28’
*Dynamic Sag values include the distance that the EcoAnchors will
potentially slide in a fall event.
In order to determine the actual Clear-Fall Distance you will need to
plan for, use the chart on the next page. 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.
