9:56 AM: Seattle Fire has a full response arriving at Alaska House apartments in The Junction for a report of a possible fire on the (update) ninth floor Updates to come.
9:59 AM: Firefighters have not yet confirmed a fire – but an alarm is sounding.
10:02 AM: Firefighters are telling dispatch that it appears the alarm was set off by dust from concrete grinding – but they’re checking every floor to be sure.
10:04 AM: And that’s now verified. They say the grinding is happening in the basement but the dust apparently has spread to multiple floors.
10:06 AM: However, firefighters have just said they “recommend to have all residents stay down in the hallways – the air is not good for breathing.” That’s of note particularly because the building is primarily for senior/disabled tenants.
10:25 AM: Just talked to the incident commander. They don’t think it was a lot of dust – they’re using a fan to clear the air.
