Inspection
KEEP INSTRUCTIONS AVAILABLE FOR REFERENCE. Record date of first use.
Prior to EACH use, inspect SRLs for deficiencies, including, but not limited to, corrosion, deformation,
pits, burrs, rough surfaces, sharp edges, cracking, rust, paint buildup, excessive heating, alteration,
broken stitching, fraying, bird-caging, and missing or illegible labels. IMMEDIATELY remove SRL from
service if defects or damage are found.
Prior to EACH use, check retraction of each lifeline by pulling out a minimum 4' and allowing them to
retract under light tension; lifelines must retract completely. Pull each lifeline sharply to test braking
function; brakes must engage. Check impact indicator for signs of deployment. Impact indicator is a
Guardian Logo tag sewn to lifeline webbing. If tag is fully visible, or if any tag stitching is broken,
DO NOT USE. IMMEDIATELY remove from service if SRL does not function properly, of if exposed to
forces of fall arrest.
Ensure that applicable work area is free of all damage, including, but not limited to, debris, rot, rust,
decay, cracking, and hazardous materials. Ensure that selected work area will support the application-
specific minimum loads set forth in this instruction manual. Work area MUST be stable.
EVERY month, a Competent Person other than the user must inspect SRLs. Competent Person
inspections MUST be recorded in inspection log in instruction manual and on equipment
inspection grid label. The Competent Person must sign their initials in the box corresponding
to the month and year the inspection took place.
During inspection, consider all applications and hazards SRLs have been subjected to.
Product Specific Applications
!
WARNING
Personal Fall Arrest: Double Blow Blockers may be used in Personal Fall Arrest applications to
support a MAXIMUM 1 Personal Fall Arrest System. Structure must withstand loads applied in
the directions permitted by the system of at least 5,000 pounds. No vertical free fall is allowed.
SRL must always be positioned at or below anchorage connection point. Applicable D-ring:
Dorsal.
Restraint: Double Blow Blockers may be used in Restraint applications. Restraint systems
prevent workers from reaching the leading edge of a fall hazard. Always account for fully
deployed length of SRL. Structure must withstand loads applied in the directions permitted by
the system of at least 1,000 pounds. No vertical free fall is permitted. Restraint systems may
only be used on surfaces with slopes up to 4/12 (vertical/horizontal). Applicable D-rings:
Dorsal, Chest, Side, Shoulder.
For all applications: worker weight capacity range (including all clothing,
tools, and equipment) is 130-310 pounds, or up to 420 pounds if used
in combination with equipment explicitly certified for such use.
Use of equipment in unintended applications may result in serious
injury or death. Maximum 1 attachment per connection point.
