Last summer both my son and daughter were lifeguards. On pool opening day they were both on duty at the same pool. Hordes of little kids came running in and managed to find the broken glass that some morons had managed to hide in the grass. So when the bloody foot patrol came running up, my kids went and got the pools official first aid kit. It contained two bandaids and a roll of gauze. Wonderful. My kids temporarily closed the pool while one of them ran next door to the store and bought supplies. After that us parents went and bought each kid a nicely stocked kit and they took these with them for all subsequent lifeguard shifts. We reported the ridiculousness of the existing first aid kits to the pool management, who did some restocking after that.
