Workers force evacuation of Dorchester apartment building by using gas-powered saw in basement

The Boston Fire Department reports that workers removing an old boiler at 16 Algonquin St. this morning set off carbon-monoxide alarms when they fired up a gas-powered saw in the basement.

You're not supposed to use gas-powered saws indoors, the department says. As soon as workers shut off the saw, readings went down, the department says, adding that the four-story building was evacuated but that nobody required medical care.
