Sources to obtain on-site information about hazardous material being transported: ✔✔Warnings
and Indicators: Shipping manifests, Placards, Labels.
Interviews: Driver, others involved in transportation of materials. Witnesses and or Victims.
Communications: Texas Law Enforcement Telecommunications System(TLETS).
*Shipper at point-of-origin.
National Incident Management System(NIMS): ✔✔* Command and Management
* Preparedness,
* Resource Management,
* Communication and Information Management * Supporting Technologies
* Ongoing Maintenance and Management
Incident Command System(ICS): ✔✔* Purposes of the ICS
* Integrated organizational structure
* ICS as a part of NIMS
Initial Assessment and Response at a Incident: ✔✔* Observations(Odors, noises, wind direction,
placards, signs, etc.)
* Assessment(Hazard level, casualties, need for additional resources, etc.)
* Plan(Response, exit strategy, precautions, etc.)
* Communicate(Dispatch, casualties, good Samaritans, etc.)
* Respond(Establish perimeter, first aid, enable ICS, etc.)
Removing Citizens from the Affected Area: ✔✔* Limit spread of contamination when moving
people that are potentially contaminated
* Establish safe travel routes for the public
* Enforce perimeter security
Minimizing Health Hazards for Responders: ✔✔* Stay outside of designed perimeter
* Remain upwind
* Wait for qualified assistance
Practical Guidelines for Law Enforcement First Responders: ✔✔Shorter times in a HAZMAT
zone are ALWAYS better. Distance and upwind location from a HAZMAT zone are ALWAYS
better.
Decontamination Concepts: ✔✔* "End the Exposure"
* Remove
* Dilute
* Absorb
* Neutralize
* Isolate
