Verso of card reads: "(Preliminary Fire Extinguishing with Jet from Stirrup Hand Pump) Much damage may be caused in an air raid by light incendiary bombs. The intense heat and smoke from such a bomb and the which it will have started make close approach impossible until the atmosphere has been cooled down and the fire partly extinguished. This is done with a jet of water from a hose not less than 30 ft. long. The stirrup hand pump . . . is recommended for this purpose. The girl in the picture is kneeling, as smoke is not so thick close to the ground."
