Paul Peterson Company supplies NCHRP-350 compliant devices
As of January 2005, the Ohio Department of Transportation started
enforcement of NCHRP-350. This standard is a crashworthiness test of
all items in the work zone. Non-certified equipment may be removed
from the job and the job may be shut down. For us, it is critical
that all of our equipment is certified. We currently have a list of
compliant items we rent and sell. Please visit the
FHWA NCHRP-350 site for further information.

NCHRP-350 Categories
-
Category 1 includes those items that are small
and lightweight, channelizing and delineating devices that have
been in common use for many years and are known to be
crashworthy by crash testing of similar devices or years of
demonstrable safe performance. These include cones, tubular
markers, flexible delineator posts, and plastic drums with no
attachments. These devices may be allowed for use on the NHS
based on the developer's self-certification.
-
Category 2 includes devices that are not
expected to produce significant vehicular velocity change, but
may otherwise be hazardous. Examples of this class are
barricades, portable sign supports, intrusion alarms, and drums,
vertical panels, or cones with lights. Testing of devices in
this category will be required. However, they may qualify for
the reduced testing requirements. The compliance date for this
category is October 1, 1998.
-
Category 3 is for hardware that is expected to
cause significant velocity changes or other potentially harmful
reactions to impacting vehicles. Hardware in this category must
be tested to the full requirement of NCHRP 350. Barriers, fixed
sign supports, crash cushions, and other work zone devices not
meeting the definitions of Category 1 or 2 are examples from
this category
-
Category 4 includes portable or trailer-mounted
devices such as Arrow Displays, Temporary Traffic Signals, Area
Lighting Supports, and Portable Changeable Message Signs. After
compliance date of October 1, 2002, this class of devices may
not be used unless they are placed behind crashworthy barriers
or shielded with TMAs or crash cushions.
