Firefighting is largely a man's world, but one suburban Boston firefighter is among a few women trying to change that.

Ashland fire Lt. Lyn Moraghan founded Camp Bailout for girls in 2011 to give them a feel for what a firefighting career entails and to provide mentoring.

The camp that launched Monday is one of about a dozen all-girl firefighting camps around the nation, seen as crucial in boosting the number of female firefighters. The National Fire Protection Association estimates that just 7 percent of firefighters are women.

On their first day, the high-school-age girls at Camp Bailout learned how to use a fire extinguisher to put out straw and propane fires. Over the week they'll learn other critical skills and hear from several women in leadership positions.
