Sheryl Smith of Wichita wants to know why nitrogen tanks are chained to some telephone poles.
First of all, it's not like there are nitrogen tanks on every other pole.
The tank Sheryl saw was at Harry & Woodlawn. Sheryl wanted to know what happens if a car hit the pole?
Verizon sources say the tanks are completely safe, saying"if a tank was punctured, nitrogen would dissipate in the air without harming anyone around it, or the environment."
A Verizon technician says nitrogen is used to pressurize underground cables to drive out moisture. The cables are not perfect, and will occasionally leak, causing shorts in copper strands. The nitrogen is used to dry them out if there is a leak.
