Four Objectives for evacuations (TRIN)
Notification
Transportation
Relocation
Information
Four instances to evacuate
- leak with unknown gas from large capacity storage containers
- explosives or large quantities of materials that could detonate or explode
- Leak that cannot be controlled and expected to continually leak
- Leak that cannot be controller involved in fire
Basic spill guidelines
- don’t wash a spill down a drain
- dike with dirt or sand
- city and County Public Works for sand/absorbent
- hydrocarbon based product spill less than 20 gallons, utilize dirt/sphagsorb and sweep to the side of the road
- flammable liquid spill should consider health concerns over fire problems
Who is responsible for clean up costs of a HAZMAT?
Person/property owner that caused the spill
After a HAZMAT spill who do you coordinate with to make contact with the state?
Coordinate with HIRT/Environmental Health to notify State OES
As a general rule who is responsible for cleanup of a HAZMAT?
Person responsible for the spill/property owner
ERG sections on guide pages
- Potential hazards (fire/explosion)

- Emergency response (Fire/spill/first aid)
- Additional green section for toxic gas/contaminated water
Small versus large spill
55 gallons liquid
660 pounds solid
When to use green section in ERG

Defensive HAZMAT tactical priorities
Define hazard zone
Isolate hazard zone
Search and evacuate exposures
Protect exposures
Three evacuation types
Site evacuation- on site personnel or immediate exposures to holding site in cold zone
Intermediate level Evacuation- off site occupancies but less than 100 people for greater period of time
Large scale evacuations- 100 to thousands of people forced out of homes for several hours. Need evacuation shelters. Close coordination with LE.
