Steam From Atop Salesforce Tower Prompts Calls To Firefighters, Social Media Stir

SAN FRANCISCO (CBS SF) – Steam from the top of the Salesforce Tower in San Francisco raised concerns among locals and even prompted calls to authorities early Wednesday.

Around 6:30 a.m., people posted on social media about possible smoke coming from the skyscraper on 415 Mission Street, the tallest in the Bay Area. The scene was particularly unsettling, with Wednesday also being the 18th anniversary of the September 11, 2001 terror attacks.

Firefighters were called to the scene. Shortly after 7 a.m., the department confirmed that it was steam from a vent, not smoke at the Salesforce Tower.

"Our Crews along with Salesforce building management were able to quickly determine that this was steam venting only. This incident is resolved. Thank you to the alert public who called 911 to report," the Fire Department said in a statement.

The stir over the steam did not go unnoticed by Salesforce CEO Marc Benioff.

"Don't worry we're just a little steamy today," Benioff tweeted, more than an hour after firefighters left the scene.
