Danger:
It is critical that CASS
®
S4(29) posts are
placed in suitable soil that will allow the system to
fully perform in accordance with design
specifications. Should you have any questions
about this, please contact the appropriate
state/specifying agency that specified CASS
®
S4(29) at this particular location for guidance.
Trinity Highway is available for consultation with
that state/specifying agency.
Warning:
Do not allow pedestrians or workers to stand
near this system, when under tension, in
circumstances where the cable may be impacted or
cut. Failure to follow this warning can result in serious
injury or death to the workers, bystanders and/or
pedestrians in the event of a vehicle impact with the
system.
Warning:
It is imperative, before assembly, that you
contact a Trinity Highway representative and
state/specifying agency engineer for special criteria for
soils which do not meet or exceed NCHRP Report 350
soil conditions. It is also recommended that you consult
your own geotechnical engineer.
Warning:
Be aware of hazards of using compressed
air (small objects may become projectiles). Failure to
follow this warning can result in serious injury or death
to the workers and/or bystanders.
Warning:
When drilling rock, it is the responsibility of
the installer to consult Occupational Safety & Health
Administration (“OSHA”) silica respiratory standard 29
Code of Federal Regulation (“CFR”) 1910.134 for
debris removal and ensure compliance
.
Warning
: Ensure that CASS
®
S4(29) delineation used
meets all federal and state/specifying agency
specifications.
Warning:
CASS
®
S4(29) shall be placed on a median
or roadside without obstructions, depressions, etc. that
may significantly affect the stability of an errant vehicle.
Grading of the site and/or appropriate fill materials may
be required. The assembler shall “flatten” or “round”
various topographical inconsistencies that could
interfere with the ability to consistently maintain the
design height (in relation to the terrain) of the cables.
To address assembly in rock, see Appendix C:
Encountering Rock.
Note:
Based on soil conditions at the site, ANY or ALL
foundations may need larger/deeper concrete footings
or larger soil plates (for driven applications) as
determined by soil analysis.
