Important: The energy absorbing HDPE Cylinders lose their ability to absorb
energy with increasing number of system impacts. After multiple full capacity
design impacts, the system will no longer be able to meet the requirements as
specified in MASH. To ensure that Cylinder replacement is accomplished before
this condition occurs, it is essential that this part of the inspection be conducted
every time the Hit Indicator indicates the system has been impacted.
The rear-most Cylinder must measure at least 26” [660 mm] for proper impact performance
(Figure 39). If distance is less than 26” [660 mm], replace all ME1 and ME2 Cylinders. If distance
is greater than 26” [660 mm], inspect all Cylinders for major cracks, tears or cuts. Replace any
damaged Cylinders. Please call the Trinity Highway Customer Service Department if you have
any questions (p. 3).
10) Ensure the system is deployed to its full length.
Caution:
Systems that are not restored to their full length may not perform to
impact performance standards of MASH.
11) Make all necessary repairs as described above and see the following page for Post-Impact
Instructions.
12) Reset Hit Indicator if necessary.
13) Note the location and condition of the QuadGuard ® Elite M10, and any work done, in your
Impact Attenuator Inspection Logbook under the date of this inspection. If further repair
is required, note repair request date in logbook. Walk-up inspections are recommended
as needed based upon volume of traffic and impact history. Refer to Post-Impact
Instructions on the next page for more information.
