asseMbly anD Use

warnIng: Do not alter or intentionally misuse this equipment. Consult if using this equipment in combination
with components or subsystems other than those described in this manual. Some subsystems and components
combinations may interfere with the proper operation of this equipment. Use caution when using this equipment
around moving machinery, electrical and chemical hazards, and sharp edges.
warnIng: Working at height has inherent risks. Some risks are noted here but are not limited to the following:
falling, suspension/prolonged suspension, striking objects, and unconsciousness. In the event of a fall arrest and/
or subsequent rescue (emergency) situation, some personal medical conditions may affect your safety. Medical
conditions identified as risky for this type of activity include but are not limited to the following: heart disease,
high blood pressure, vertigo, epilepsy, drug or alcohol dependence, psychiatric illness, impaired limb function
and balance issues. We recommend that your employer/physician determine if you are fit to handle normal and
emergency use of this equipment.
3.1 BEFORE EACH USE inspect this equipment according to steps listed in section 5.3. 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 DBI‑SALA 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 PLAN y our fall arrest system before starting your work. Take into consideration factors affecting your safety at any
time during use. The following list gives some important points you must consider when planning your system:
A. ANCHORAGE: Select an anchorage point that is rigid and capable of supporting the required loads. See
section 2.4. Locate the roof anchor in accordance with section 3.3.
B. OTHER CONSIDERATIONS:
• Place the Counterweight System at least 8 ft (2.5 m)
away from any edge or opening. See Figure 4.
• Personal fall arrest systems must be rigged to limit
any free fall to a maximum of 6 ft. (1.8 m) (OSHA
and ANSI Z359.1) (see section 1.2 F).
• Avoid working above your anchorage level since an
increased free fall distance will result.
• Avoid working where your line may cross or tangle
with that of another worker or another object.
• Do not allow the lifeline to pass under arms or
between legs.
• Never clamp, knot or otherwise prevent the lifeline
from retracting or being taut, avoid slack line.
IMPortant: Do not lengthen the SRL by connecting a lanyard or similar component without consulting
DBI‑SALA.
C. TOTAL FALL DISTANCE: Should a fall occur, there must be at least 15 ft of clearance in the fall area
to arrest the fall before striking the ground or other object (see Figure 4). The total fall distance is the
distance measured from the onset of a fall to the point where the fall is arrested. A number of factors
can influence the total fall distance including; user's weight, anchorage location relative to the fall (swing
fall), body support with sliding D-ring, and the type of fall arrest equipment you attach to the LEAP
anchor. For specific clearance requirements read and follow the manufacturers's instructions for your fall
arrest equipment.
D. SWING FALLS: See Figure 5. Swing falls occur when the anchorage point is not directly above the
point where a fall occurs. The force of striking an object while swinging (horizontal speed of the user
due to the pendulum affect) can be great and may cause serious injury. Swing falls can be minimized
by working as close to the anchorage point as possible. In a swing fall situation, the total vertical fall
