Around 8:15 p.m. Saturday night July 9, Baltimore County (MD) Fire Department Engine 13 (Westview station) was dispatched for an automatic fire alarm at the Days Inn hotel in the 5700 block of Baltimore National Pike in Catonsville. Upon arrival, firefighters had smoke showing from a 7-story hotel building and requested a full fire box. Firefighters found fire on the upper floors of the hotel and had a difficult time getting water, and made several rescues via aerial ladder. The fire quickly escalated to four alarms with multiple additional equipment special called to the scene. Mutual aid was sent from Baltimore City Fire Department, Maryland Air National Guard at Martin State Airport (air unit), Carroll County's Lineboro Volunteer Fire Department (Air Unit 7), and Cabin John Park Volunteer Fire Department in Montgomery County, which sent its airboat to assist with ventilating smoke from the building. More than 160 occupants of the hotel escaped the fire, with two transported to an area hospital to be treated for smoke inhalation. One firefighter also suffered minor injuries. The fire's cause and origin are under investigation by the Baltimore County Police Department Arson Unit continues to investigate the fire, which they believe began in a locked seventh-floor storage room. Fire investigators estimate that the fire caused about $2.5 million worth of damage to the hotel and about $1 million to the hotel's contents.
