Operation And Use - 3M DBI SALA 5908549 User Instruction Manual

3.0 OPERATION AND USE

WARNING: Do not alter or intentionally misuse this equipment. Consult
3M Fall Protection when using this equipment in combination with
components or subsystems other than those described in this manual.
Some subsystem and component combinations may interfere with the
operation of this equipment. Use caution when using this equipment
around moving machinery, electrical hazards, chemical hazards, and
sharp edges.
WARNING: Consult your doctor if there is reason to doubt your
fitness to absorb the impact from a fall arrest. Age and fitness can
affect your ability to withstand fall arrest forces. Pregnant women and
minors must not use this system.
3.1 BEFORE EACH USE inspect this equipment according to section
5.0. Do not use this equipment if inspection reveals an unsafe or
defective condition. Plan your use of the fall protection system
prior to exposing workers to dangerous situations. Consider all
factors affecting your safety before using this system.
A. Read and understand all manufacturer's instructions for each
component of the personal fall arrest system. All 3M Fall
Protection harnesses and connecting subsystems are supplied
with separate user instructions. Keep all instructions for future
reference.
B. Review sections 1.0 and 2.0 to ensure system limitations and
other requirements have been adhered to. Review applicable
information regarding system clearance criteria, and ensure
changes have not been made to the system installation (i.e.
length) or occurred at the job site that could affect the required
fall clearance. Do not use the system if changes are required.
3.2 SYSTEM INSTALLATION: Figure 1 shows a typical Sayfline
horizontal lifeline installation. When using an energy absorbing
lanyard to connect to the system, the end anchorages must be
located at a height which will limit the free fall to 6 feet (1.8m).
When using a self retracting lifeline (SRL) to connect to the
system, the end anchorages must be located above the user. The
SRL, when fully retracted, must be above the harness attachment
level. The horizontal lifeline system should be positioned at a
level that will minimize free fall while allowing ease of use. The
horizontal lifeline should be positioned near the work location to
minimize swing fall hazards. The connecting subsystem length
should be kept as short as possible to reduce the potential free
fall and required clearance distance. Both anchorages must
be installed at approximately the same elevation, so that the
horizontal lifeline system is not sloped more than 5°.
Step 1. Determine the locations of the end anchorages and
evaluate their strengths in accordance with section 2.4.
Determine the span length and evaluate the required
clearance using Figures 4, 5, or 6 and Tables 1, 2 or 3.
