The purpose of this annex is to outline operational concepts and organizational arrangements for firefighting during emergency situations at LSCS. LSCS, is dependent upon local firefighting agencies to provide fire service including the responsibility for rescue, warning, and radiological protection operations as addressed in Annexes R, A, and D, respectively.

Concept of Operations

The Harris County (HCFMO), Montgomery County (MCFMO), San Jacinto County (SJFMO) and City of Houston (COHFMO) Fire Marshal’s Offices are responsible for coordinating fire protection efforts for their respective jurisdictions within the LSCS service area. Actual fire service will be provided by local fire departments (FDs) which operate independent of each other. Fire services have the primary responsibility for protecting our community from fire hazards, hazmat spills, and radiological incidents. During emergency operations, local FDs may require assistance from the following agencies:

  1. Law enforcement – LSCS Police, Harris County Sheriff’s Office, or Constables
  2. EMS – local EMS provider
  3. LSCS Facilities
  4. Local public works – local MUD or FWD
  5. IC and specialized hazmat support -- HCFMO
  6. Additional resource support – mutual aid partners, HCFMO, COHFMO, SJFMO, HCOHSEM, and Texas Forest Service
  7. Medical Examiner - Harris County Institute of Forensic Sciences
  8. County Attorney

A listing of local fire department resources is found in Annex M, Resource Management. During routine operations, FD’s and other first responders should communicate on their local frequencies. During a disaster, all agencies should have functional interoperable communications.
