What is the UH Outdoor Warning Siren System?
The University of Houston Outdoor Warning Siren System is designed to alert persons on campus of an emergency situation that requires them to seek shelter indoors for their safety. There are three sirens located on the highest points of campus so that it can effectively alert persons outdoors throughout the campus.

When is it used?
The UH Outdoor Warning Siren System will only be used when there is an imminent threat to the lives and safety of people on the UH campus where it is unsafe to be outdoors. This threat could come in the form of severe weather, an environmental threat such as a hazardous chemical release, or some other emergency situation.

What should I do if I hear the UH Outdoor Warning Siren System?
