This incident resulted in a minor injury to one of his colleagues.Power outages affected more than 170 households in Seoul's Seongbuk district at 5:30 a.m., likely due to trees falling on telegraph poles and electric wires under the snow's weight, as reported by the Korea Electric Power Corp. Additional households in Eunpyeo ng-gu experienced power interruptions. In Gangwon Province, car crashes due to heavy snow resulted in one fatality and nine injuries.The adverse weather conditions also impacted air travel, with 150 flights canceled nationwide, including 71 flights at Incheon International Airport, as per the Korea Airports Corp. and Incheon International Airport Corp.
