mine is similar to Russ's kit... don't overlook several pairs of nitrile gloves and disinfectant wipes for any first responders, and some way to irrigate with clean water... chance of battery acid or glass in the face... a mylar blanket to cover the deceased

a note... if you need to use a dry chemical extinguisher on a vehicle fire, with others in attendance... give them a warning first... breathing the powder is not pleasant
