As an alternative to developing exclusionary performance-based selection standards, the approach of this study was to modify the demands of shipboard damage control tasks by using mechanical aids. Tasks selected included a manikin drag maximum distance in 30 sec and a CO2 bottle extinguisher carry sec. A tether device and a shoulder strap were developed to improve performance on the respective tasks. Subjects were 24 women and 23 men stationed onboard the USS Emory S. Land AS-39. Results indicate that average manikin drag distance was 8.lm for men and 25.2m for women. Although no difference was observed between the two drag techniques, use of the tether significantly reduced overall rating of perceived exertion RPE. On average, CO2 bottle extinguisher carry times for women were 59 slower for women than for men. Use of the shoulder strap did not significantly affect time to complete the task or overall RPE. However, RPE for the right arm and right hand were reduced significantly during the strap-assisted carry 38 and 48, respectively. These prototype devices have been refined and utility in similar and sustained damage control task scenarios have been assessed.
