Seriously guys... The ground rod will give you a good ground, but the problem is static discharge.
Unless EVERYTHING in the proximity of the equipment is at the same potential, you risk an ESD event that can create a spark.
When you are standing on a wet concrete floor wearing Nikes, your hand is NOT at the same potential as the bench that is resting in that water until you touch it.
JUST grounding your bench can create an even worse situation. I was working in Victorville in a bucket 30ft up, about 70ft below the HVAC lines crossing the desert from Hoover Dam to Fontana.
I was getting "bit" from the traffic signal gear.
The pole was obviously grounded... but my body was not. I was standing in a fiberglas bucket 30ft above the ground.
I touched the signal pole with my fingertip and slowly drew it back. I was able to produce and HOLD an arc almost an inch long.
