Does invasive pole inspection reduce pole strength?

To some extent. With Genics products it is not necessary to drill a hole any larger than 1/2". It has been shown mathematically that 3  - 1/2" holes drilled at 45 degrees 120 degrees apart will reduce a 40" circumference pole by less than 1.5%. Most procedures call for 6" vertical separation of drill holes reducing this to less than 0.5%.

 
Are the chemicals used for treatment toxic?

Genics Inc. produces and distributes the most environmentally responsible and safe to use wood pole treatment products available. The toxicity of the chemicals comprising the products has a toxicity to mammals somewhere between that of salt and table sugar. Our employees prefer Genics products.

  
I have noticed that many utilities only check the pole above ground. Is below ground inspection necessary?

Yes! It is imperative that the shell below ground line be checked for surface decay. Most of the strength of a wood pole lies in the outer 2" of the pole.
