Large font and simple text tell who firefighters are and what they do.  These men and women put out fires, help others, and visit schools and talk about fire safety.  Special clothing protects them from heat and smoke, tools help get water to the fire.  Different trucks also have specific uses: carry water, pump water, extend ladders.  When on duty, many firefighters live at the fire station so they will be ready to respond to emergencies.  Each spread has a large photograph to accompany the text.  Glossary, index, additional reading and an internet site included.
