Purpose
The 3M Concrete Anchor Straps are designed to be used
as part of a personal fall arrest system, to help limit the fall
arrest forces in the event of a fall.
Use Instructions
1. Failure to follow all instructions and limitations on the
use of Concrete Anchor Straps may result in serious
personal injury or death.
2. Before using a personal fall arrest system, employees
must be trained in accordance with the requirements of
OSHA 29 CFR 1910.66 in the safe use of the system and
its components.
3. Personal fall arrest systems, including Concrete
Anchor Straps, must be inspected prior to each use for
wear, damage, and other deterioration and defective
components must be immediately removed from service,
in accordance with the requirements of OSHA 29 CFR
1910.66 and 1926.502.
4. The complete fall protection system must be planned
(including all components, calculating fall clearance, and
swing fall) before using.
5. Users must have a rescue plan, and the means at
hand to implement it, that provides the prompt rescue
of employees in the event of a fall, or assures that
employees are able to rescue themselves.
6. Store Concrete Anchor Straps in a cool, dry, clean
environment, out of direct sunlight, when not in use.
7. After a fall occurs, the Concrete Anchor Straps must be
removed from service and destroyed immediately.

3,600 lb (16.0 kN) with certifi cation of a qualifi ed
person, or 5,000 lb (22.2 kN) without certifi cation.
3. Concrete Anchor Straps are designed to be used in
temperatures ranging from -40ºF to +130ºF (-40°C to
+54°C).
4. Do not expose Concrete Anchor Straps to chemicals
or harsh solutions which may have a harmful effect.
Contact 3M Technical Service with any questions.
5. Caution must be taken when using Concrete Anchor
Straps near moving machinery, electrical hazards,
sharp edges, or abrasive surfaces, as contact may cause
equipment failure, personal injury, or death.
6. Minors, pregnant women and anyone with a history
of either back or neck problems should not use this
equipment.
7. Do not use or install equipment without proper training
from a "competent person" as defi ned by OSHA 29 CFR

8. Only 3M, or persons or entities authorized in writing by
3M, shall make repairs or alterations to the equipment.
Compatibility Limitations
All 3M Concrete Anchor Straps must only be coupled to
compatible connectors. OSHA 29 CFR 1926.502 prohibits
snaphooks from being engaged to certain objects unless
two requirements are met: snaphook must be a locking
type and must be "designed for" making such a connection.
"Designed for" means that the manufacturer of the snaphook
specifi cally designed the snaphook to be used to connect to
the equipment in question. The following connections must
be avoided, as they are conditions that can result in rollout*
when a nonlocking snaphook is used:
• Direct connection of a snaphook to horizontal lifeline.
• Two (or more) snaphooks connected to one D-ring.
• Two snaphooks connected to each other.
• A snaphook connected back on its integral lanyard.
• A snaphook connected to a webbing loop or webbing
lanyard.
• Improper dimensions of the D-ring, rebar, or other
connection point in relation to the snaphook dimensions
that would allow the snaphook keeper to be depressed by
a turning motion of the snaphook.
*Rollout: A process by which a snaphook or carabiner
unintentionally disengages from another connector or object
to which it is coupled. (ANSI Z359.1-2007)
Performance
3M Concrete Anchor Straps have a minimum tensile
breaking strength of 5,000 lb (22.2 kN) when statically tested
