Limitations and Warnings
Trinity Highway, in compliance with NCHRP Report
350, contracts with ISO 17025 A2LA accredited
testing laboratories to perform crash tests, evaluate
tests, and submit the test results to the FHWA for
review.
The CAT® System has been deemed eligible
by FHWA as meeting the requirements and
guidelines of NCHRP Report 350, Test Level 3
(“TL-3”). These tests typically evaluate product
performance defined by NCHRP Report 350
involving a range of vehicles on roadways,
from lightweight cars (approx. 800 kg [1,800 lb.])
and full size pickup trucks (approx. 2,000 kg [4400
lb.]) at 100 kph [62 mph].
The CAT® is tested pursuant to the test matrix
criteria of NCHRP Report 350 as designated by
FHWA. The FHWA tests are not intended to
represent the performance of systems when
impacted by every vehicle type or in every
impact condition existing on the roadway. Every
departure from the roadway is a unique event.
Trinity Highway expressly disclaims any warranty or
liability for injury or damage to persons or property
resulting from any impact, collision or harmful
contact with its products, other vehicles, or nearby
hazards or objects by any vehicle, object or person,
whether or not the products were assembled in
consultation with Trinity Highway or by third parties.
The
CAT®
is intended to be assembled, delineated,
and maintained within
the state/specifying agency
and
federal guidelines. It is important for the
state/specifying agency to select the most appropriate
product configuration for site specifications.
The state/specifying agency’s careful evaluation of
the site layout, vehicle population type and speed,
traffic direction, and visibility are some of the
elements that require evaluation in the selection of
a highway product. For example, curbs could cause
an untested effect on an impacting vehicle.
After an impact with the system, all debris must be
removed from the area immediately in compliance with
the most applicable state/specifying agency policy. The
specified CAT® must be evaluated and restored to its
original specified condition or replaced as the
state/specifying agency determines/requires, as soon
as possible. Product selection, approval, proper
installation, and maintenance of any highway product is
the sole responsibility of the state/specifying agency.
Safety Alert Symbols appear throughout this
manual and indicate Danger, Warning, Caution or
Important statements. Failure to read and follow
these warnings could result in serious injury or
death in the event of a vehicle impact with the
system.
WARNING: Do not assemble, maintain, or repair
the CAT® until you have read this manual
thoroughly and completely understand it. Ensure
that all Danger, Warning, Caution, and Important
statements within the manual are completely
followed. Please
call Trinity Highway at (888)
356-2363 if you have any questions about
instructions in this manual.
WARNING: Safety measures
incorporating
appropriate traffic control devices and personal
protective equipment ("PPE") specified by
the
state/specifying agency must be used to protect
all personnel while at the assembly,
maintenance, or repair site. Work gloves, apron,
eye protection, safety-toe shoes, and
back
protection shall be used.
WARNING: Ensure the assembly site meets all
appropriate Manual on Uniform Traffic Control
Devices (“MUTCD”) and the state/specifying
agency standards.
WARNING: Use only Trinity Highway parts that are
specified by Trinity Highway for use with the CAT®
for assembling, maintaining, or repairing the
CAT®. Do not utilize or otherwise commingle
parts from other systems even if those systems
are other Trinity Highway Systems.
Such
configurations have not been tested, nor have they
been approved for use. Assembly, maintenance or
repairs using unspecified parts or accessories is
strictly prohibited. Failure to follow this
warning could result in serious injury or death
in the event of a vehicle impact with such an
UNACCEPTED system.
WARNING: Do NOT modify the CAT® in any way.
IMPORTANT:
Trinity
Highway
makes
no
recommendation whether use or reuse of any part
of the CAT® is appropriate or acceptable after
system impact. It is the responsibility of the
state/specifying agency
and its engineers to make
that determination.
IMPORTANT: It is the responsibility of
owner,
state/specifying agency, or specifier
to inspect the
CAT® after assembly is complete to ensure the
instructions provided in this manual have been
strictly followed.
