Maintenance, Cleaning, and
Storage
If Halo Big Block SRL fails inspection in any way,
immediately remove it from service, and contact
Guardian to inquire about its return or repair.
Cleaning after use is important for maintaining
the safety and longevity of Halo Big Block SRL.
Remove all dirt, corrosives, and contaminants
from Halo Big Block SRL before and after each
use. If Halo Big Block SRL cannot be cleaned with
plain water, use mild soap and water, then rinse
and wipe dry. NEVER clean Halo Big Block SRL
with corrosive substances. When not in use, store
equipment where it will not be affected by heat,
light, excessive moisture, chemicals, or other
degrading elements.
Limitations
Fall Clearance: There must be sufficient
clearance below the work surface to arrest a
fall before the user strikes the ground or an
obstruction. When calculating fall clearance,
account for a MINIMUM 2 ft (0,6 m) safety factor,
deceleration distance, user height, length of
lanyard/SRL, harness stretch, free fall, and all
other applicable factors.
See Diagram B on page 7.
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.
Compatibility
When making connections to the Halo Big Block
SRL, eliminate all possibility of roll-out. Roll-out
occurs when interference between a connector
and the attachment point causes the connector
gate to unintentionally open and release.
All connections must be selected and deemed
compatible with Halo Big Block SRL by a
Competent Person.
All connector gates must be self-closing, self-locking,
and withstand a minimum load of 3,600 lb (16 kN).
See Diagram A on page 7.
Installation and Use
WARNING! Guardian Halo Big Block
SRLs MUST NEVER be used in Leading
Edge (LE) applications.
No free fall is allowed.
ALWAYS avoid lifeline contact with sharp or
abrasive edges and surfaces.
Prior to Installation, plan your system
1. All components of the PFAS must be selected
and deemed compatible with SRL by a
Competent Person.
2. Ensure structure to which SRL is to be
attached, and on which work is to be
performed, is free of all hazards, including,
but not limited to, debris, rot, rust, sharp or
abrasive edges and surfaces, and hazardous
materials.
3. Halo Big Block SRL may be used in stationary
applications only; attach Halo Big Block SRL
carabiner to selected anchorage connector,
and attach snap hook to applicable harness
D-ring.
4. Ensure 100% tie-o will be maintained at all
times, which may require the use of a back-up
or supplementary fall protection system.

Safety Information
WARNING! Failure to understand and
comply with safety regulations may result
in serious injury or death. Regulations
included herein are not all-inclusive, are
for reference only, and are not intended
to replace a Competent Person's (CP)
judgment or knowledge of federal or state
standards.
Do not alter equipment.
Do not misuse equipment.
Workplace conditions, including, but not limited
to, flame, corrosive chemicals, electrical shock,
sharp objects, machinery, abrasive substances,
weather conditions, and uneven surfaces, must
be assessed by a Competent Person before fall
protection equipment is selected.
The analysis of the workplace must anticipate
where workers will be performing their duties,
the routes they will take to reach their work, and
the potential and existing fall hazards they may
be exposed to. Fall protection equipment must be
chosen by a Competent Person. Selections must
account for all potential hazardous workplace
conditions. All fall protection equipment should
be purchased new and in an unused condition.
Fall protection systems must be selected and
installed under the supervision of a Competent
Person, and used in a compliant manner. Fall
protection systems must be designed in a
manner compliant with all federal, state, and
safety regulations. Forces applied to anchors
must be calculated by a Competent Person.
Unless explicitly stated otherwise, the maximum
allowable free fall distance for lanyards must not
exceed 6’ (1.8 m).
Harnesses and connectors selected must be
compliant with manufacturer’s instructions, and
must be of compatible size and configuration.
Snap hooks, carabiners, and other connectors
must be selected and applied in a compatible
fashion. All risk of disengagement must be
eliminated. All snap hooks and carabiners must
be self-locking and self-closing, and must never
be connected to each other.
See Diagram A on page 7.
A pre-planned rescue procedure in the case
of a fall is required. The rescue plan must be
project-specific. The rescue plan must allow for
employees to rescue themselves, or provide an
alternative means for their prompt rescue. Store
rescue equipment in an easily accessible and
clearly marked area.
Training of Authorized Persons to correctly erect,
disassemble, inspect, maintain, store, and use
equipment must be provided by a Competent
Person. Training must include the ability to
