25 impact on urinal ops. Due to the marginal airflow, it was not possible for the female crewmember to do the same for hygienic reasons. Urinal ops were terminated the evening of flight day 4 due to the inability to dump the waste tank. Apollo fecal collection bags and some emesis bags were utilized for urine collection the remainder of the mission. These bags were found to be totally unacceptable for this purpose, and a different backup urine collection scheme needs to be devised. The WCS accessories bag (holds personal funnel covers and urine filters) is supposed to be deployed on the back wall of the WCS. However, this arrangement blocks access to the stowage compartment on the port side of the WCS. It is recommended that the accessory bag be designed for deployment on the starboard WCS wall. When activating the WCS it was found there was no velcro on the Orbiter wall to mate with the extended privacy curtain velcro. Trash Trash stowage volume was adequate. On the evening of flight day 4 the wet trash volume cover was raised and it was estimated the volume was approximately half full. From this point until reentry, the crew used the wet trash only for the urine bags (48 Apollo bags plug 4 emesis bags) and it was totally full at reentry. While inserting an Apollo bag which contained a towel for urine absorption, the rubber grommet over the wet trash was pulled out of its holder. Until the wet trash was used for urine stowage, there was no odor from the volume. Even after the urine was stowed, an odor was noticeable only when the cover was opened. One of the long, narrow food package trash bags was periodically used to compress the wet trash to achieve maximum volume. A crewmember would insert his arm into the bag and reach into the wet trash to force items away from the entrance. This procedure worked well and it is recommended that spare food package bags be carried for this purpose. The dry trash volumes (Volume B) were also used for food container stowage, particularly beverage containers (containers sealed in plastic bags) after flight day 4. The volume was adequate and there was no odor problem. Miscellaneous The fabric foot restraints are extremely useful. We recommend that more be placed in the cabin relaunch. 41-D had three on the aft flightdeck floor and four on the middeck floor. While the optimum number and placement is probably flight specific, it was felt that one could not err in having too many. Four on the aft flightedck floor and six on the middeck floor would probably be a reasonable relaunch configuration with others stowed for crew deployment, especially with larger crew size.
