Note:
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 42). 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 Customer Service if you have any questions (p. 3).
9) 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.
10) Make all necessary repairs as described above and see the following page for Post-Impact
Instructions.
11) Reset Hit Indicator if necessary.
12) Note the location and condition of the QuadGuard
®
Elite M10 Wide, 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 for more information (p. 41).
