Lessons that are learned while visiting the Indianapolis Firefighters Museum

• The horse-drawn chemical wagon is like a big Soda Acid fire extinguiser. Sodium Bicarbonate was dropped in the top hatch and the chemical reaction created pressure to charge the hose lines. It was used for quick attacks on small fire outbreaks.
• The horse-drawn steam pumper was built in 1898. It is an American LaFrance type 3 Metropolitan.
• The hand pumper was built in 1850 and probably was used in a small town or factory. Water was pumped by hand from streams, lakes and puddles for putting out fires.
