Hazardous Material Commodity Flow Map

Fire & Rescue


Conducting Commodity Flow Studies (CFS) that examine the HazMat Shipments and their associated hazards moving along the State's transportation system contain critical information for improving HazMat emergency response capabilities and life safety. Sharing that information with the emergency response community can benefit all.

California Governor's Office of Emergency Services (Cal OES) created this webpage to:

  • Determine were CFS have been completed and where they are needed
  • Build a mechanism to share CFS with local emergency responders and planners
  • Assist local jurisdictions in determining the HazMat risks within their communities
  • Assist local jurisdictions in improving their HazMat emergency response capabilities
  • Facilitate Hazardous Materials Emergency Preparedness (HMEP) Grants for eligible agencies to conduct CFS


This webpage displays:

  • Icons on a map of California representing locations where CFS were conducted by jurisdictions throughout the state
  • CFS brief summaries, including abstract and contact information, while hovering your cursor over the icons

Jurisdictions throughout the state voluntarily provided the CFS information to Cal OES for inclusion on this webpage. Request to add your jurisdiction's CFS information to this webpage.
