Information from the alarm company, along with reports from occupants in neighboring businesses indicated the presence of smoke coming from the Aqua Nails Bar. First-arriving fire crews encountered dark grey smoke inside the Aqua Nails Bar and also found the fire sprinkler system activated. Additional firefighters arrived and began to evacuate neighboring businesses within the complex which contained more than a dozen retail shops, office spaces and restaurants. Due to the size of the structure and the volume of smoke, the incident commander requested a second alarm for additional firefighting resources. Firefighters worked on scene for over 40 minutes to evacuate smoke and water, and to salvage belongings. Although fire damage was contained to the Aqua Nails Bar, some adjacent businesses had moderate smoke damage. There were no injuries. Assisting TVFR firefighters on scene were crews from the Lake Oswego Fire Department, Gladstone Fire Department, Clackamas Fire District, and AMR ambulance. A TVF&R fire investigator is working to determine the cause of the fire.
