Children at Kadena Elementary School use a pulley system to easily move a heavy stretcher with a dummy on it during fire prevention week Oct. 5, 2016, at Kadena Air Base, Japan. Kadena firefighters brought their trucks, equipment and smoke trailer to the schools on base to teach kids the importance of fire safety, how to check smoke alarms and what to do in the case of a fire.
