Subjects studied in Fire School are; fire department organization, public relations, first aid, chemistry of fire, ventilation theory and practice, forcible entry, rescue and salvage, building code, radiology, tools and equipment, and other technical subjects. Each student makes a notebook which he keeps as reference and study aid. In addition to classroom studies, ladder and hose drills, and rescue procedures, the rookie is involved in a physical conditioning program. The very nature of the fire fighters work demands that he be in good physical shape. Techniques of emergency removal of trapped victims or firemen from tall buildings are demonstrated at the state fair.
