What are the different control zones/perimeters for a hazmat incident?
Support/Cold zone/green/outer - ICP, medical group, etc, members do not have to wear SCBA
Contamination Reduction/Warm zone/yellow/secondary - safe refuge and decon, wearing one level below
Exclusion/Hot zone/red/inner - area of isolation, only individuals with specific tasks in proper gear
perimeter - outside security line around all control zones
Who can provide an MSDS/SDS sheet?
- Workplace involved in incident
- Manufacturer and/or distributer of product
- CHEMTREC
What are the limits of protective clothing material?
Penetration - movement of chemicals through zippers, stichted seams or imperfections in the material.
Degradation - loss of or change in the fabric’s chemical resistance or physical properties due to exposure to chemicals, use (or misuse) or ambient conditions (sunlight)
Permeation - process by which a chemical dissolves in and/or moves through a protective clothing material on a molecular level.
What are the typical methods of defensive containment?
5D FC
Dike - make small curb with dirt
Dam - build overflow dam for product that sinks
Divert - build small dike to change direction
Disperse - apply fog spray in chlorine cloud
Dilute - apply water to water soluble material
Cover - lay salvage cover over powder spill
Foam - apply AFFF to large gasoline spill
What are the different types of dams?
Simple dam - barriers across a waterway or between two objects intended to hold back flowing water or material.
Underflow dam - used for release involving materials that float on water
Overflow dam - used for release involving materials that sink in water
What are the typical methods of offensive control?
Plug and patch - fix hole or valve in drum
Absorb/Adsorb - apply pads to spill
Transfer - remove product to waste vacuum truck
Containerize - put leaking drum into overpack drum
Stop - reposition drum or shut off valve
What is technical decon?
- responder decontamination
- provided for personnel working in exclusion zone and/or contamination reduction zone (hot/warm zones)
- normally done by Hazmat group
What is emergency decon?
- urgent, field expedient process
- use any available water source
- intended for exposed persons displaying symptoms
- normally done by first responders
- usually done prior to setting up formal decon
What is the Hazardous Materials Group Org chart?
- operations section chief
- Hazmat group supervisor
(3 report to HazMat group sup) - entry leader
- site access control leader
- decontamination leader
(reports to decon leader) - decontamination element
What notifications are mandatory?
- Local Dispatch
- Administering Agency/CUPA
- CalEMA Warning Center
- National Response Center
What is the difference between flammable and combustible liquids?
flammable liquid - below 141F.
combustible liquid - above 141F.
*per OSHA, the cut off is 100F.
What is the difference between flammable liquids and combustible liquids?
Per FRO flammable = flash point <141F
combustible = flash point >141 F
Most common is flash point of 100 F
What markers should be in place for pipeline markers?
- marked with words “Warning, Caution, Danger”
- followed by the name of hazardous liquid transported (ie. Petroleum or Carbon Dioxide Pipeline”
- POC (point of contact) information
Where must pipeline markers be located?
- each public road crossing
- railroad crossing
- along each buried line
May be: waterways or underwater crossings
Every Hazmat response should have what 2 things?
- Safety Officer assigned (one who has knowledge in the operations being implemented)
- Site Safety Plan (preferrably in writing)
