On Monday, February 22nd the entire Yorba Linda High School Staff was trained on the use of emergency supplies and what to do in an active shooter situation. Jake Ching and his partner Brandon from Los Angles County Fire spent the day showing teachers basic first aid and how to use the supplies provided for each classroom. Each teacher received a backpack with emergency supplies and a bucket with lock down or long term disaster supplies provided through a partnership between Eastside Christan Church and PYLUSD.
