Article: Lisa Pina never thought she would need the fire safety training she received during her apprenticeship as a union painter and dry waller. On Friday morning,she was thanking God she had _ . On Thursday night,while Pina was babysitting her granddaughter,nephew and two nieces in her sister's apartment,she smelled smoke and realized the apartment building was on fire. When her 4yearold granddaughter Ilean Garcia began saying,"We're going to die,"she knew she had to act.Pina,39,first sealed the door,and then told all four children to get on the floor. After calling 911,she told the children to start singing and promised them all treats as soon as they reached safety. "I said,'OK,we're going to lie down and we're all going to play a game,'" Pina said. "We all started singing our ABCs and 123s.I was just trying to make it fun." Pina patiently waited,and a few minutes later,Riverside County sheriff's deputies arrived. Pina,Ilean,8yearold Gabriel Parga,5yearold Aubreyana Parga and 4yearold Meriyah Parga were all trapped on the second floor as flames filled the first story. Pina did the only thing she could. She opened the window and dropped the children,onebyone,into the arms of the sheriff's deputies about 15 to 20 feet below. "I just needed to keep the kids calm so they wouldn't be afraid,"Pina said."I was deathly afraid inside,but I couldn't let them know that."[Not long after dropping the children out of the window,firefighters arrived with a ladder and rescued her. Ten people were treated at the scene for suffering smoke,but nobody was seriously injured.
