All checked out OK on May 5 at Page Avenue Village in Wiscasset after fire and rescue crews responded to make sure there was no carbon monoxide problem, Wiscasset Fire Chief T.J. Merry said. A man who lives there had gone from his workplace to a hospital with an elevated level of carbon monoxide in his blood, so crews were just checking to make sure levels were OK at home, Merry said. All four apartments in the block where the man lives had no evidence of a carbon monoxide problem, Merry said.
