A great number of professional rescuers are needed after huge disaster such as earthquake, whose rest and health gain less attention than the injured. This makes them exhausted and difficult to keep work well done continuously. The Friendly Helmet has an inflatable pillow and a pair of eyeshades inside it, convenient for the rescuer to take a nap in any condition, so that they can continue work well later.
