142's title is IEEE Recommended Practice for Grounding of Industrial and
Commercial Power Systems
It's divided into separate sections on "what do do with a structure" ,
"what to do with specific manufacturing processes", and "how to connect
it to Earth"
For instance, there's stuff about dusty areas (flour mills and bakeries,
for example)
It doesn't say much about towers, per se.
