Alan and others,
My approach has been to not require gloves rated above the output of the electrofisher (e.g., linesman's gloves) for practical concerns (i.e., too heavy, thick, and hot). It seems unreasonable to employ gloves that must withstand the operator touching both anode and cathode (or two electrodes of an AC unit). Careful operators should never encounter that situation. I've approached the glove issue primarily to ensure a dry, non-conductive barrier between the operator and the water. This also means keeping your hands relatively dry from sweat, leaks, or splashes inside the gloves. I've tried to purchase gloves with some kind of fabric or cotton inner liners (attached to glove), which absorb minor amounts of moisture (about $10/pair at a hardware or farm store). So far, so good, and no one's been shocked -- at least not due to conductive waders or gloves -- but are we assuming reasonable risk?
Is the above approach reasonable? Smith-Root (a US manufacturer of electrofishing gear) suggests that "all personnel should wear rubber lineman's gloves and a safety helmet." They sell gloves for $85/pair, rated to 5 kV, which extend up to the elbow. Then you should periodically test those gloves for leaks at considerable additional expense. Is it practical to use shorter gloves that are not rated? What's with the helmet? Can we be practical and safe? How much assumed risk is reasonable?
Alan, what do you and Jim Reynolds recommend when teaching the US Fish and Wildlife Service training course?
