Specifications
for Guardian Safety Barrier
Intent
It is the intent
of this specification to describe a lightweight portable
plastic barrier. The intended use of the GUARDIAN Barrier
is to prevent vehicular penetration of a work zone, traffic
channelization, pedestrian control, security barriers, erosion
control, street and road closures and blockading, race track
safety barriers, etc.
Scope
This specification
recognizes the need for a lightweight and portable barrier
to perform some of the functions of cement barriers, rubber
cones and barrels and other such devices used to control,
direct, channel and stop pedestrian traffic for purposes
of containment and/or safety.
Construction
The barrier is
made using the rotational molding method to ensure watertightness
integrity. It is available in three sizes: 42 inches (Standard),
28 inches (Lowered) or 54 inches (Extended), each with a
base width of 24 inches. The usable, un-nested length is
72 inches with an additional 6 inch protrusion to one end
to form the male connection. Opposite the male end is a
6 inch intrusion of the same shape to accept the male protrusion
to form a continuous wall connection. The barrier has, in
the center, a filling hole which is 4 1/2 inches in diameter.
The sides of the barrier have two sloping surfaces, the
topmost being nearly vertical and the lower surface being
approximately 25 degrees from vertical. The lower sloping
surface will terminate at the top of an 8 inch vertical
rise. On the bottom of the barrier are two 6 inch wide forklift
slots. All corners in all areas of the barrier shall have
no less than a 1 inch radius. A drainage hole and plug on
the lower area is placed within a drainage slot in such
a fashion as to be readily accessible. The barrier shall
have the appearance of the precast concrete barrier.
Material
The material used
is a recyclable low-density polyethylene. It is rotationally
molded to a thickness of 8 millimeters and is uniform in
thickness.
Ultraviolet
Light
An ultraviolet
light inhibitor is introduced into the raw material mix
so as to provide sufficient protection to ensure reasonable
life of the product in outside weather conditions.
Colors
The standard colors
of the barriers are opaque ivory, international yellow and
safety orange. Other colors may be introduced form time
to time, however, they must conform to state and federal
specification on uniform color-coding and/or military specifications,
or as specifically requested by the customer.
Baffles
There are a plurality
of baffles molded into the bottom of each barrier and extending
upwardly inside the barrier for a distance of 14 inches.
The baffles are a necessary part of the structural integrity
of the barrier. The baffles shall make intimate contact
with the exterior corrugations along each side of the barrier.
Gussets
The barriers shall
have gussets (or corrugations) molded in each side that
will begin at the top of the vertical rise in the base of
the side. These gussets will coincide with the edges of
each baffle to form a uniform, side-to-side monolith.
Weight
The 42-inch barrier
shall not exceed 170 lbs. when empty, and will accept up
to 1,525 lbs. of liquid or solid ballast. The 28-inch barrier
shall not exceed 90 lbs. when empty, and will accept up
to 1,100 lbs. of liquid or solid ballast. The 54-inch barrier
shall not exceed 195 lbs. when empty, and will accept up
to 1,825 lbs. of liquid or solid ballast. Each shall retain
both their shape and structural integrity when filled. |
