Here is something that never occurred to me before but should have. Irrigation is made up of long metal poles and equipment that is out in the field and can be frequently hit by lightning because it is often the tallest thing in the field. I did not realize that it can hold a charge that could be dangerous to any farmer or helper that touches it. This article from Southeast Farm Press describes this in more detail and tells you how to use a voltage detector to help protect yourself from electrocution. Be safe and know how to protect yourself from lightning, both when you are out in the field and when it hits your equipment!
