In Use Installation Toxic releases to the general public and worker exposure. Since utility poles are virtually everywhere, public exposure to them is widespread. Preservative depletion while a pole is in service represents the most significant release reported in the literature, although it is acknowledged that there has not been adequate research.
Dermal exposure poses a significant risk to utility workers who install and climb poles.
Splinters from the pole can also carry toxic materials directly into the bloodstream. Workers who handled CCA-treated wood have been awarded compensation by the courts. Toxic chemicals can seep out of poles, resulting in concentrations of highly contaminated soil, or pooled liquid residue at the base of poles. Many of these poles are in cities, parks, playgrounds and backyards. The bare ground around a pole in a backyard may provide the pet cat's favorite place to find loose soil.
