OC Supervisor Katrina Foley Commends First-Responders Following Potential Haz Mat Threat in Costa Mesa

ORANGE COUNTY, CALIFORNIA — Orange County Supervisor Katrina Foley released a statement following an incident in Costa Mesa where authorities discovered hazardous explosive materials in a resident’s garage. The OC Sheriff’s Department (OCSD), the OC Health Care Agency (HCA) Haz Mat Emergency Response team, the Costa Mesa Police Department (CMPD), and the Costa Mesa Fire Department (CMFD) safely removed a crystallized jar of Picric Acid from the home for safe detonation. 

“I applaud the OC Sheriff’s Department, the OC Health Care Agency, the Costa Mesa Police Department, and the Costa Mesa Fire Department for quickly averting a potential crisis by swiftly and safely removing the hazardous, explosive materials from the residence,” said Supervisor Katrina Foley. “Public safety remains one of my top priorities. Our residents can rest easy knowing our law enforcement and safety teams are well trained, equipped, and own the tools to continue to keep our communities safe.”


Because crystallized picric acid is sensitive to heat, shock, friction and detonation, OCSD used a containment vessel to safely transport together with CMPD to detonate the jar at the Bee Canyon greenery at the Frank R. Bowerman landfill in Irvine.
