If you need to do mass 1st aid for a bunch of lacerations that are not life theatening, I think you should go the route we do for houses: 3M Vetwrap bangages, preferaably 3", a full box or more of 4 x 4 telfa non-sticks, twice that many boxes of 4 x 4 gauze, a can of antibiotic spray, like Furacin, and several cans of spray sterile saline.

Roughly debride with saline, spray on some Furacin, slap on a telfa pad and a couple of gauze pads, and sent them out the door. In such an emergency, there is not time for more.
