Abstract : This report documents engineering investigations of potential toxicity hazards in enclosed Navy gun mounts and techniques for hazard elimination. Guns ranged in bore size from 3 to 16 in. Carbon monoxide emerged as the primary threat to health. A severe potential hazard was isolated in certain mounts. Design factors involved are: (1) propellant charges; (2) breech opening times; (3) bore evacuators; (4) gas ejectors; (5) case ejection times; and (6) mount ventilation provisions. Tactical factors involved are: (1) number of rounds fired; (2) rate of fire; and (3) relative winds. (Author)
