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?

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 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?

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)
