Overview

• A propane-powered concrete saw used improperly during unpermitted construction in the same building as the Kittery day care caused carbon monoxide exposure.
• Eleven individuals, including seven children, were hospitalized with non-life-threatening symptoms but released the same night.
• The Building Blocks Learning Center staff quickly evacuated 27 children and 10 staff members after noticing an odor and symptoms of sickness, preventing a more severe outcome.
• Investigators found that carbon monoxide likely entered the day care through an HVAC duct or exposed ceiling during construction, and some detectors near the saw were covered.
• The Maine State Fire Marshal’s office is continuing its investigation into the incident, including assessing the building's alarm system and potential legal violations.
