Fire trucks lined Neil Avenue Thursday as firefighters went to work in a building that wasn’t even on fire.Ohio State gave permission to the Columbus Division of Fire to use the Neil-17th building for training exercises for firefighters.”We’ve got a great working relationship with the university,” said, Charles Bardocz, battalion chief. “It is great that they gave us this building to use.”The building, which has been vacant about a year, is scheduled to be torn down in about two months, said John Kleberg, assistant vice president of business and administration.”We work with (the fire department) to provide training opportunities and communication between their equipment and the university police,” he said. “It’s a very cooperative working relationship.”Firefighters from all over Columbus came together to learn rescue techniques for situations in which they may need to rescue fellow firefighters.”We’re always taught how to save citizens, and it hasn’t been until recently that there has been a focus on how to save firefighters,” said Robert Karn, a Columbus firefighter.Firefighters practiced rescuing other firefighters who had fallen through a hole in the floor, maneuvering a firefighter out of an extremely confined space inside a building, saving a firefighter by means of a ladder, and a self-rescue technique.The techniques are tough, but it is imperative that the victim is rescued out of the building as quickly as possible, Bardocz said.”This was a teaching scenario,” Karn said. “It was a learning experience for a lot of people.”Approximately 100 firefighters are killed by fire each year, he said.”There have been numerous situations across the country where firefighters have died in the line of duty while attempting to make rescues or just fight a fire,” Bardocz said. A course called ‘Saving Our Own’ was developed in Champaign, Ill., by fire personnel around the nation who had lost firefighters to similar situations, and they developed techniques for those situations, Bardocz said. “It showed a lot of people the need for these techniques,” said Karn, who had attended the course.Once firefighters have learned how to perform these rescue techniques, they will try them in more realistic conditions by adding artificial smoke.
