Exposure to UV and Weather PAGE 03 Polyethylene pipe products are protected against deterioration from exposure to ultraviolet light and weathering effects. Color and black products are compounded with antioxidant's, thermal stabilizers and UV stabilizers, Color products use sacrificial UV stabilizers that absorb UV energy and are eventually depleted. In general, non -black products should not remain in unprotected outdoor storage for more than two years; however, some manufacturers may allow longer unprotected outside storage. Black products contain at least 2% carbon black to protect the material from UV deterioration. Black products with and without stripes are generally suitable for unlimited outdoor storage and for service on the surface or above grade. Cold Weather Handling Temperatures near or below freezing will affect polyethylene pipe by reducing flexibility and Increasing vulnerability to impact damage. Care should be taken not to drop pipe, or fabricated structures, and to keep handling equipment and other things from hitting pipe. ice, snow, and rain are not harmful to the material, but may make storage areas more troublesome for handling equipment and personnel. Unsure footing and traction require greater care and caution to prevent damage or injury, Walking on pipe can be dangerous. Inclement weather cavi make pipe surfaces especially slippery WARNING: Keep safety first on the jobsite; do not walk on pipe.
