AMBULANCE VENTILATION.
Ford ambulances in the service of the A.E.F. are to be bored with one inch auger holes at three-inch intervals in double rows through the wooden front just at the driver's back and immediately beneath the roof; in the tail-board, also, there will be fifteen holes. This is to secure proper ventilation, as deaths have been known to occur, in other Allied services, within the enclosed bodies of the ambulances which are equipped with exhaust gas heaters. Ambulance drivers are cautioned to investigate the condition of their passengers at five-minute intervals.
