ORIGINAL 9:32 AM REPORT: In case you heard this from eastern West Seattle, or a workplace along the Duwamish: Fire crews are still on the scene at a South Park business where something exploded within the past hour. KIRO TV links aerial photos from its online story and identifies the business as Independent Metals; SFD spokesperson Helen Fitzpatrick tells our partners at the Seattle Times as well as KING5 (their report here) that everyone’s accounted for. While the 911 log shows a massive response, scanner traffic indicates some of the units have been canceled. There’s no official word yet on injuries, though the scanner mentioned at least two patients, one of which was being handled with a private ambulance, which indicates non-life-threatening injuries. According to its website, Independent Metals is a scrap-metal recycling company that’s been in business more than a quarter-century.

10:01 AM: SFD has just posted online that indeed, there were two people hurt, “minor injuries.” The explosion is blamed on a propane tank going into a metal shredder. We’re adding an SFD photo of some of the damage on the building’s exterior.
