Personnel assigned to the 502nd Logistics Readiness Squadron utilize a water pump to squeeze water through a gas mask drinking tube to clean out a gas mask more efficiently Nov. 13 at Joint Base San Antonio-Lackland. Jason Rios, 502nd Logistics Readiness Squadron material handler, had the idea to use a water pump to effectively eliminate the need to perform the slow and arduous squeezing action from the old way of using a canteen. Rios entered the Air Force Spark Tank competition with his idea on Oct. 29, 2020, but was not chosen to represent Air Education and Training Command at Spark Tank, but the idea is being refined and may be expanded to other AETC installations.
