SPECIFICATIONS:
This fall arrest anchor is for single and multiple users on a low slope roof application (4/12 pitch or less). A Horizontal line fall restraint system
of up to four workers may be used if designed and inspected by a qualified person.
RECOMMENDED INSTALLATION:
Roof Anchors must be installed and spaced a maximum of 20ft. apart. Installation around the perimeter of the leading edge areas is
recommended to ensure compliance and allow the user to easily switch from anchor to anchor. Recommended spacing is between 6 and 10ft.
from edge of roof. Do not install the roof anchor on unsupported roof structures such as overhangs or inadequately secured decking.
1. ANCHORAGE: Select an anchorage point that is structurally secure and capable of supporting the required loads, see below installation suggestions.
2.CONSIDERATIONS: Personal fall arrest systems must be rigged to limit any free fall to a maximum of 6 ft. 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.
3. FALL DISTANCE: Should a fall occur, there must be sufficient clearance in the fall area to arrest the fall before striking the ground or other
object. 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 roof anchor. For specific clearance requirements read and follow the manufacturers’s
instructions for your fall arrest equipment.
4. SWING FALLS: 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 directly below 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. A commonly followed guideline is not to extend your work zone over 30° from
the anchorage point.
5. SHARP EDGES: Avoid working where the connecting subsystem or other system components will be in contact with, or abrade against
unprotected sharp edges. If working with this equipment near sharp edges is unavoidable, protection against cutting must be provided by
using a heavy pad or other means over the exposed sharp edge. Compatibility and total fall distance issues must be considered if this is done.
WARNING: This product is part of a personal fall arrest system. The users must read and abide by the manufacturer’s instructions for each
element of the system. Installation of this roof anchor must be certified by a qualified person or engineering service. These
directions must be given to the users of this equipment. The users must read and understand these instructions or have them explained
to them before using this equipment. Manufacturer’s instructions must be followed for proper use, care and maintenance of this product.
Alterations or misuse of this product or failure to follow instructions, may result in serious injury or death
