1.04 PRODUCT DELIVERY, STORAGE, AND HANDLING

A. Thermoplastic pipe shall be stored on the job site in accordance with AWWA
M23 and the manufacturer’s recommendations. Thermoplastic pipe that has been
subjected to excessive ultraviolet radiation from the sun shall not be used.
Noticeably faded materials shall not be installed and shall be promptly removed
from the site.

B. Store thermoplastic pipe in the field by supporting the pipe uniformly per AWWA
M23. Do not stack the pipe higher than 1.22 m (4 feet) or with weight on the bell
ends. Cover stored thermoplastic pipe to protect it from the sun’s ultraviolet
radiation. Pipe that has been contaminated with any petroleum products (inside or
outside) shall not be installed.

rejection of the materials.

D. Equipment used for unloading shall be covered with wood or rubber to avoid
damage to the exterior of the pipe, fittings, and accessories. Do not drop or roll
materials off trucks. All thermoplastic pipe shall be handled with padded slings
or other appropriate equipment. The use of cables, hooks or chains will not be
permitted.

E. The materials shall be inspected before and after unloading. Materials that are
found to be cracked, gouged, chipped, dented, or otherwise damaged will not be
accepted.

F. Interiors of pipe, fittings, and accessories shall be kept free from dirt and foreign
matter.

G. Store pipe and fittings on heavy wood blocking or platforms so they are not in
contact with the ground.

H. Pipe, fittings, and specials shall be unloaded opposite to or as close to the place
where they are to be used as is practical to avoid unnecessary handling.
