Controlling crowds and directing traffic may look easy, but it can be dangerous at times.
"You have to be on your toes. You don't want another accident to happen or someone getting hit," said Joshua McFarland, a new member of the Hagerstown City Police Department's volunteer Fire Police division.
Fire police are given the responsibility of crowd control and directing traffic at fires, accidents and crime scenes.
They may have to stand for hours at a scene and deal with motorists who can be disgruntled at the prospect of being detoured.
They are also there to direct traffic for special events such as concerts at the Maryland Theatre.
McFarland said he doesn't take it personally when confronted by upset motorists and doesn't find the job physically taxing.
"You're adrenaline gets pumping," he said.
For McFarland, 24, joining the Fire Police was a way to meet people after moving to Hagerstown from Pennsylvania more than a year ago.
