Seems y'all might need to have a major meeting with Bozo McGadget. Even the version that shoots a stream, instead of a spray, will generate a mist when it hits something. Flushing with copious amounts of water is the recommended immediate first aid. I have heard of a product sold through police supply places that will neutralize it in the field, but I doubt is is intended for use in the eyes. Don't use any soap or such before the affected area has been flushed well with plain water, and you don't want to open the skin's pores with too-warm or hot water.
