 Well, gloves, that's one of the primary forms of safety, first line of defense really. We have rubber gloves that protect us. That's really the first thing, once we get in the bucket, we have on so we can touch anything that's primary. You know, we're on the ground, we take them out of the bag, we test them, do visual inspection, just to make sure while we're doing the job, we didn't get no pin hole, no cuts, anything in the glove or we'll do the air test or you can put water in there and just fold it down and get some air in there or something water and just look listen see there's air coming out of the glove or water coming out gloves are pretty much our first line of defense right there.
