Abstract
This report describes an evaluation of the Graesby Otto fuel monitor OFM 2. This Otto fuel monitor was procured to replace the aging MK 15 Mod O Otto fuel vapour detectors used on ships and submarines. Shortly after introduction of the Graesby OFM 2 to the fleet inexplicably high levels of atmospheric Otto fuel contamination were reported on several instances. These high positive indication of atmospheric contamination caused considerable concern regarding either potentially hazardous conditions to human health or the reliability of the new unit. Therefore DREA Dockyard Laboratory was requested to conduct a laboratory evaluation of the new monitors and this report describes the preparation and calibration of gas phase standards that were used to evaluate the Graesby OFM 2 response to atmospheric propylene glycol dinitrate (PGDN) concentration from Otto fuel. The unit was found capable of detecting PGDN atmospheric levels of 0.018 parts per million (v/v) and the response of the unit increased with increasing concentration up to 0.049 parts per million (v/v).
