Installation and Use
4.1
Plan the Personal Fall Arrest System (PFAS):
Inspect the HLL subsystem before each use in accordance with the procedures detailed in
Section 6. Examine the work area and take action to address hazards. Falls are a serious hazard when working at height. Training and
equipment are the tools of fall hazard management. There are several closely related facets of fall hazard management with a PFAS;
•
Anchor Point Selection
•
Anchorage Connector
•
Deceleration Device
•
Maximum Arrest Force
•
Deceleration Distance
•
Minimum Required Fall Clearance (MRFC)
•
Body Wear
•
Rescue
4.2
Anchor Point Selection:
Select a suitable anchor point. Consider the area where the work is being performed. In an overhead anchorage
condition, the area below the anchorage is the work zone. Lateral movement away from the anchorage is hazardous. As distance from
the anchor increases, the work zone expands, and so does the hazard. Work zone expansion is measured in feet and has a direct influence
on user safety. Always work as close to the anchor as possible.
If used in applications with leading edge hazards, anchorage locations must be selected so that the deflected HLL shall not come in
contact with a leading edge in the event of a fall. For below D-ring anchor point installations for use with this HLL system, contact
PALMER SAFETY
4.3
Anchorage Connector:
Anchorage Connectors used as part of a PFAS should be designed for use with specified anchor points and
compatible with the PFAS components and connectors to be used in the assembly of a complete PFAS. Care should be taken to ensure
proper assembly, installation and maintenance of all Anchorage Connectors to be used when planning a PFAS. Failure to inspect,
assemble, install and/or maintain Anchorage Connectors could result in injury or death.
4.4
Connectors/Deceleration Devices:
Connectors and Deceleration Devices such as Shock Absorbing Lanyards, Self-Retracting
Devices/Lifelines, and Fall Arrestor Connector Subsystems (Vertical Lifeline/Rope Grab Combinations) are designed to connect the
user’s
body wear to the Anchorage Connector and/or Anchor Point of a Personal Fall Arrest System.
4.5
Product Assembly and Installation:
System installation requires end anchor points that are a minimum of 5,000 lbs. (22.2 kN) for one
and two workers, see Figure 8. The lifeline shall be installed higher above the shoulder
to limit free fall to 6’ or less*. When using SRDs
the lifeline must be positioned overhead and the SRD must be have anti-racheting design. The horizontal lifeline should be positioned in a
manner to minimize free fall while allowing ease of use. Movement away from the lifeline should be limited to reduce the potential for
swing fall. Lifeline end anchors should be installed at approximately the same elevation so that the lifeline itself is not sloped more than 5
degrees.
Step 1:
Determine the location of the end anchorages and, in accordance with Section 3.2, evaluate their strength. Determine the span
length of the system and determine the minimum required clearance for safe use in accordance with Section 2.7.
Step 2:
Install the end anchorage connectors. The PALMER SAFETY 2-Person Temporary HLL system comes with 2 pass-through anchor
straps for wrapping around columns. If using pass through anchor straps, ensure strap is wrapped at least twice around the end
anchorage, see Figure 9. This will help prevent sliding of the anchor straps during use. If using alternative anchorage connectors, please
ensure the connectors are compliant and conform to the requirements of Section 3.2. Not all anchorage connectors are designed for use
with horizontal lifeline systems. In all cases, refer to the user’s instruction manual for the end anchorage connectors to be
used.
