Do you know what to do in the event of a major disaster such as the San Bruno pipeline explosion? The Office of Emergency Services oversees the city's disaster plan and coordinates relief and recovery plans with the state and FEMA. In addition, OES provides trainings for residents, from CPR to search and rescue. Milpitas has sirens in the northwest and southwest parts of the city. Residents who hear the siren should seek shelter and follow instructions from city media, such as radio station 1620 AM and TV station channel 15, or the City of Milpitas website.
