It Must Be Tuesday @Noon
Most people who live and/or work in San Francisco have heard the City’s Outdoor Public Warning System. Although most are familiar with the sirens—and perhaps even check their watches by it—the point of the system is to alert the public to an emergency and is one of several tools DEM uses to disseminate alerts and warnings.
The test message and siren tone you hear every week are just one way for us to make sure the system is in good working order. The sirens are run by radio technology, and like any technology, routine maintenance is required. During the next several weeks, the sirens will be undergoing said scheduled maintenance. (But the weekly test will still happen as usual.)
We wanted to take this opportunity to remind you that while the sirens are one of the most well-known forms of emergency notification, we also have many other tools to disseminate alerts. If you haven’t already tapped into them, now is a great time to opt in.
Other Means of Receiving Emergency Alerts
Anyone who lives and works in San Francisco is highly encouraged to sign up for the City’s text and email based alert system, AlertSF. We use AlertSF to communicate life-safety and other emergency information. We will also tweet any incidents of citywide significance via @sf_emergency. Tuning into the news on radio (such as KCBS 740 AM or 106.9 FM) and TV also is a good way to get information about an emergency.
At the heart of the matter: we encourage you to check as many information sources as possible.
