Abstract
Prior to the Canadian Navy's move to the new Victoria class submarine (former RN Upholders), DCIEM was tasked to re-examine the air quality on an Oberon class submarine to determine if the atmosphere complied with Air Purificatoin Standard BR 1326. The objective of the study was to obtain information to assist in developing plans for future submarine air quality management. Since the information would be directly applicable and transferable to the Victoria submarines, the conduct of a trial on an Oberon was warranted. This trial represents a baseline evaluation of submarine air quality under patrol conditions. Over a 24-hour period, the functional and detection capabilities of analytical instruments for monitoring the atmosphere were assessed and a 'fingerprint' of the contaminants onboard was obtained. A profile of Carbon Dioxide (CO2) accumulation and Oxygen (O2) consumption was determined and the effectiveness of air purification (CO2 scrubbing; O2 generation; and, snorting) was assessed. In addition, Carbon Monixde (CO) was monitored and Carboxyhemoglobin (COHb) was measured in representative smokers and nonsmokers, Ammonia (NH4), Ozone (O3), and Nitrous compounds (NOx) were measured to assess, respectively, whether the sanitary systems, electrical systems, and engine exhaust gases posed any problems.
