What should I do when I receive an alert?

Follow the directions of CMU-Alert messages unless doing so will place you in greater danger. CMU-Alert warnings are intended to support decisions for personal safety. When you become aware of a warning, make sure others around you are also aware of the potential danger. DO NOT respond to the scene of an emergency unless directed to do so. In addition to the possibility of becoming injured, your presence could interfere with the work of emergency response personnel.

How can I keep CMU-Alert messages from being marked as spam?

It is recommended that you list the CMU-Alert number, 412-268-ALRT, in your cellphone as a contact, and white-list the number in any third-party spam-identification applications such as Hiya, NoMoRobo, and Robokiller. In most cases, this should prevent an erroneous "Spam Risk" identification from appearing on your cellphone.
