Assembly AND Use

WARNING:
Do not alter or intentionally misuse this equipment. Consult with DBI‑SALA if using the Roof Top Counterweight
Anchor System 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 4.3. Do not use the Roof Top Counterweight
Anchor System 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 your 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 Roof Top Counterweight Anchor System at least 2.5 m away from any edge or opening (see A and C in
Figure 4).
• Personal fall arrest systems must be rigged to limit any free fall to a maximum of 1.8 m (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 5.2 m of clearance in the fall area to arrest the
fall before striking the ground or other object (see B in 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. These factors include the 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 Roof Top Counterweight Anchor System.
Users must add 1.5 meters (5 ft) into fall clearance calculations to account for any movement in the counterweight
anchor base while arresting a fall. For specific clearance requirements read and follow the manufacturer's instructions
for your fall arrest equipment.
D. SWING FALLS: Swing falls occur when the anchorage point is not directly above the point where a fall occurs (see A
in Figure 5). 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. Unexpected hazards can increase the chance of injury in a swing fall (see
B in Figure 5.). Swing falls can be minimized by working as close to the anchorage point as possible. In a swing fall
situation, the total vertical fall distance of the user will be greater than if the user had fallen vertically directly below
the anchorage point. The user must therefore account for an increase in the total free fall distance and the area
needed to safely arrest the fall.
The SRL (if applicable) will activate (lock-up) regardless of it's orientation and location relative to the user's position,
however, a commonly followed guideline is work as directly between the anchorage point and roof edge as possible.
Do not captivate the lifeline of an SRL, it may affect the performance of its braking. If a swing fall hazard exists in
your application, contact DBI-SALA before proceeding.
E. SHARP EDGES: (See Figure 6) Avoid working where the subsystem (i.e. SRL (E), full body harness (C),
lanyard,lifeline, etc.) or other system components connected to the anchor system (D) will be in contact with or
abrade against unprotected sharp edges (A). If working with this equipment near sharp edges is unavoidable a
Leading Edge SRL should be used. If one is not available, protection against cutting must be provided by using a
heavy pad or other means over the exposed sharp edge (B), and use an SRL approved for horizontal or factor 2
usage.
WARNING:
Read and follow the manufacturer's instructions for associated equipment (i.e. SRL, full body harness, lanyard,
lifeline, etc.) used in your personal fall arrest system.
