Image of the Guardian Safety Barrier 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.
