The Maine Fire Marshal’s Office on Saturday will get the keys to a new command post donated by a former Mainer whose company specializes in building mobile facilities.

Gil and Anne Blais, owner of La Boit Inc. of Ohio, are Lewiston natives. They are donating the 33-foot mobile command post to help the Fire Marshal’s Office conduct investigations. The facility includes a workstation, conference rooms, a bathroom and a galley for cooking meals.

Investigators with the Fire Marshal’s Office respond to suspicious fires and explosions across the state to determine the cause and, if they are arson, help identify suspects.

The $180,000 command center will be presented to the state at the Central Fire Station, Two College St., in Lewiston Saturday at 10:30 a.m. Gov. Paul LePage is expected to be on hand for the presentation.
