Warning:
Use only Trinity Highway parts on the Vulcan
®
Barrier for assembly,
maintenance, or repair. The assembly or comingling of unauthorized parts is
strictly PROHIBITED. The Vulcan
®
Barrier and its component parts have been
accepted for state use by the FHWA. However, a comingled system has not
been accepted within the applicable criteria.
Important:
Trinity Highway makes no recommendation whether use or
reuse of any part of the system is appropriate or acceptable following an
impact. It is the sole responsibility of the local highway authority and its
engineers to make that determination. It is critical that you inspect this
product after assembly is complete to make certain that the instructions
provided in this Manual have been strictly followed.
Warning:
Ensure that this assembly conforms with the guidance provided by
the AASHTO Roadside Design Guide, including, but not limited to, those
regarding placement on or adjacent to curbs.
Limitations and Warnings
Trinity Highway, in compliance with the National Cooperative Research Highway Program 350
(NCHRP Report 350) “Recommended Procedures for the Safety Performance of Highway
Safety Features,” contracts with FHWA approved testing facilities to perform crash tests,
evaluation of tests, and submittal of results to the FHWA for review.
The Vulcan
®
Gate has been approved by FHWA as meeting the requirements and guidelines of
NCHRP Report 350. These tests typically evaluate product performance defined by Report 350
involving a range of vehicles on roadways, from lightweight cars (approx. 820 kg [1800 lb.]) to
full size pickup trucks (approx. 2000 kg [4400 lb.]). The Vulcan
®
Gate is certified to the Test
Level(s) as shown below:
Test Level 3: 2000 kg [4400 lb], 100 km/h [62 mph], 25 degrees
Test Level 4: 8000 kg [17,600 lb], 80 km/h [50 mph], 15 degrees
These FHWA directed tests are not intended to represent the performance of systems
when impacted by every vehicle type or every impact condition existing on the roadway.
This system is tested only to the test matrix criteria of NCHRP Report 350 as approved by
FHWA.
Trinity Highway neither represents nor warrants that the impact results of these federally
established test criteria prevent or reduce the severity of any injury to person(s) or damage to
property. These tests only demonstrate the occurrence of certain results following an impact
within NCHRP Report 350 criteria. Every departure from the roadway is a unique event.
The Vulcan
®
Gate system is intended to be assembled, delineated, and maintained within
specific state and federal guidelines. It is important for the highway authority specifying the use
of a highway product to select the most appropriate product configuration for its site
specifications. Careful evaluation of the site lay out, vehicle population type; 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 occurs, the debris from the impact should be removed from the area
immediately and the specified highway product should be evaluated and either restored to its
original, specified condition, or replaced, as the highway authority determines, as soon as
possible.
