Flashcards in Hazardous Materials Book Deck (43):
What are the primary functions of the hazmat IC structure?
Who bears all responsibility of managing the incident
What must IAP (Incident Action Plan) have in order to be completed?
Must be in writing and include:
Site Safety Plan
Goals & Objectives
Who dictates that a hazmat incident must be operated with an incident management system (IAP) in place?
OSHA and EPA
When was the use of NIMS implemented and mandated?
If other positions of responsibility are not needed, who will assume those duties?
If the section of the structure go unassigned, who will have responsibility?
What are the (3) critical responsibilities of the IC?
1. Assume and Announce command and establish an effective operating position
2. Rapidly evaluate the situation by conducting a thorough and complete size up
3. Initiate, maintain and control the communication process
Is the Unified Command structure the most efficient and safest means of operation?
What is the concept of a Unified Command?
All agencies that are functionally involved in the Incident contribute to the process
What is the purpose of a Unified Command?
To help determine strategies and overall incident objectives and help plan jointly for tactical objectives
In the US structure, who directs the IAP?
Operation Section Chief
Who would be the Operations Section Chief of an Incident?
The jurisdiction having the greatest involvement and shall be designated by all agencies represented in a Unified Command.
What are the responsibility of the Hazmat Branch?
To manage all tactile operations carried out within the control zones
What does the Hazmat Branch manage?
Containment and Confinement
Sampling medical monitoring
What does the NFPA recommends?
the use of risk base response to hazmat incidents pr emergencies
What two factors does NFPA evaluate when utilizing the risk management matrix?
severity and probability
The severity of a chemical hazard focuses on what four areas concerning the hazard?
What is the Eight Step Process?
It is the tactical decision making model that focuses on Hazmat/WMD incident safe operating practices
what are the steps of the Eight Step Process?
1. Site Management and control
2. Identify the problem
3.Hazard Assessment and risk evaluation
4. Select protective clothing and equipment
5. Info management and resource coordination
6.Implement response objectives
8. Terminate the incident
What is HazmatIQ?
a four step process decision making response model that is used by major fire and law enforcement agencies in the US
What are the 4 HazatIQ steps?
1. A quick chemical size up
2. A streamline chemical size up using supplied charts
3. Meter selection
4. PPE selection
What does DECIDE response model stand for?
Detect, Estimate, Choose Response, Identify, Do best option, Evaluate progress
What is the DOT (8) step response model?
1. Approach cautiously uphill, upwind
2. Secure the scene
3. Identify the hazard
4. Assess the situation
5. Obtain help
6. Decide on site entry
8. Above all, do not assume
What action are taken during Nonintervention?
Allows the incident to run its course
What actions are taken during Offensive?
Includes actions to control the incident such as plugging and diking. Responders take aggressive measures, direct action on the material, container or process of equipment involved in the incident.
What actions are taken during Defensive?
Provides confinement of the hazard to a given area by performing diking, damming or diverting actions. Responders seek to confine the emergency to a given area without directly contacting the hazardous material involved.
What is the Medical Surveillance plan?
Consists of medical monitoring. should start far before the incident.
Who is the Medical Surveillance plan required by?
OSHA 29 CFR 191.120.
What is the four point system for the Medical Surveillance plan?
1. A baseline physical
2. An annual physical
3. An exposure physical
4. An exit physical
A way of expressing the weight of liquid and solids
is the measure of thickness or flowability of a liquid at a given temperature
describes compounds that contain no water or crystals that lack chemically bound water of crystallization
is the minimum temperature to which a substance must be heated so it produces enough vapor to support sustained combustion
means dry or without water.
element that will repel water. example car wax
use when referring to corrosives and oxidizers. Will react with spill control products such as saw dust or other cellulose bases
Bases (or Caustic)
are materials that produce hydroxide ions when dissolved with water
Halogens, organic compounds and peroxide salts are examples of:
matter that can change it state from solid to liquid, liquid to gas and back again
is the temperature at which the vapor pressure of a liquid is equal to the atmospheric pressure around the liquid.
