Resources During a Disaster

GKN Aerospace HazMat Incident

Orange County has transitioned its emergency response operations back to normal business. As part of this change, all questions or concerns related to reimbursement, personal / individual claims or similar matters should now be directed to the owner / operator GKN Aerospace- http://gkngg.com/. For information related to small business claims, please see the Business & Disaster Recovery Resources section of the website below.

Beginning May 29, 2026, the Orange County Health Care Agency (HCA), serving as the County's Certified Unified Program Agency (CUPA), will lead multi-agency site cleanup and waste removal activities related to the incident, working closely with GKN Aerospace (where the incident occurred).

During the cleanup process, air monitoring will be conducted at the GKN Aerospace fence line and in the community under the oversight of South Coast Air Quality Management District (AQMD). The U.S. Environmental Protection Agency (EPA) will provide technical advisory support to South Coast AQMD and the HCA throughout the cleanup phase. Updates regarding the site cleanup and waste removal will be posted on www.occupainfo.com.

Hi-Lo Siren

Some of the Sheriff's Department's patrol units are now equipped with a new siren feature to alert residents to evacuation orders during emergencies, such as a fire or flood. The system also is equipped with an external PA system that can play recorded messages to notify residents about the need to evacuate.

Our priority during any emergency is your safety, and this new tool will help bolster our response efforts during mass evacuations. Remember: When you hear hi-lo, it's time to go!
