My grandpa was a firefighter for a long time. Besides controlling and put out fires, he saved people from burning buildings. He did a lot of another things, too. After the fire, he had to check and clean his tools so that they were always ready to the next fire. He also learned of new ways to put out fires and new things to help him did his job. Now, he has new job. He does not go into burning buildings anymore. Grandpa visits schools to share knowledges about fire safety. He showed students the burn marks on his old coat. He tells everyone how to prevent fires and how to do if there is a fire and how to be safely. My grandpa is a hero.
