In addition to everything that was already mentioned, our spill kit includes two small flat plastic shovels, actually sandbox toys, to use for scooping the contaminated baking soda into the plastic bag with the leaking battery. Our gloves are hazmat-type gloves with rough surfaces so that a wet, slippery battery can be safely handled.
The best training video I've found to illustrate how to spot and properly take care of a battery leak can be found at
http://www.youtube.com/watch?v=noRe87GWIqI. Students and mentors who handle our batteries or are part of our safety crew will all see this video, and then we discuss how this would relate to our size batteries and environment.
Please be careful with batteries, and be ready for an accident, even if it never happens.
