PARMA, Ohio - The city of Parma has a large industrial area, which means there are huge factories like the GM plant.
Like firefighters throughout northeast Ohio, those in Parma get a lot of training in industrial fires and chemical fires. But you can't always go "by the book" when you're trying to save lives.
Parma firefighter Doug Turner said firefighters do yearly inspections and a walk-through of area factories to become familiar with the plants.
They keep pre-planning books that detail what types of chemicals are in the plants and where they're located.
Firefighters also rely on the Emergency Response Guidebook, which matches the codes of hazardous chemicals and informs firefighters how to fight the fire. It also tells them which chemicals have the potential to explode or contain hazardous fumes.
If no lives are in danger and the huge fire is out of control, sometimes firefighters will back off and let the fire burn itself out.
But because firefighters want to save lives, backing off isn't in their blood.
