An early morning fire at TidalHealth Peninsula Regional has been ruled accidental.

The fire was reported at around 1:25 a.m., in an Environmental Services Storage Closet. Crews were able to control the blaze in just over 20 minutes.

Maryland State Fire Marshals say the fire involved an electric vacuum cleaner attached to the wall and was caused by the failure of a lithium-ion battery. The incident reportedly took place in an employee-only area and was controlled by the automatic sprinkler system. No patients were displaced or required evacuation, and hospital operations were not affected. The sprinkler and alarm system were placed back in service.
