3 hurt in explosion in building on Rockland waterfront

ROCKLAND, Maine (AP) - Fire officials say three people were hurt in an explosion on the waterfront in Rockland, Maine.

Officials say sparks from a grinder ignited fumes from a 55-gallon drum that had contained chemical stripping agent, causing the explosion Thursday night.

All three were hospitalized. Officials say one of them was transported via LifeFlight to a burn center. Identities weren’t immediately released.

Firefighters say the victims may have made things worse by trying to douse the fire themselves instead of immediately calling the fire department.
