Re: pic: Design Challenge: Pits

I have seen teams manufacture lighting solutions from parts obtained from big box stores. They then manufacture power distro to provide power to all of the lights and then use a custom method of mounting these lights to the metal parts of the structure without any known good protective ground. This allows the metal framework, under certain conditions, to become elevated above ground. In and of itself, a danger but may not be fatal. However when someone contacts a grounded system in the adjacent pit while contacting (i.e. holding on to) the structure you suddenly have a serious possibility of loss of life, spark hazard and fire. I have seen things that curl my hair, what's left of it.
