Hazardous Materials Book Flashcards
What are the primary functions of the hazmat IC structure?
Operations
Planning
Logistics
Finance/Administration
Who bears all responsibility of managing the incident
Incident Commander
What must IAP (Incident Action Plan) have in order to be completed?
Must be in writing and include:
Pre-incident survey Response modes Hazard Assessment 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?
2003
If other positions of responsibility are not needed, who will assume those duties?
IC
If the section of the structure go unassigned, who will have responsibility?
IC
What are the (3) critical responsibilities of the IC?
- Assume and Announce command and establish an effective operating position
- Rapidly evaluate the situation by conducting a thorough and complete size up
- Initiate, maintain and control the communication process
Is the Unified Command structure the most efficient and safest means of operation?
Yes
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?
Site Safety Rescue Entry Operations Decon 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?
Health
Fire
Reactivity
Radioactivity
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?
- Site Management and control
- Identify the problem
- Hazard Assessment and risk evaluation
- Select protective clothing and equipment
- Info management and resource coordination
- Implement response objectives
- Decontamination
- 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?
- A quick chemical size up
- A streamline chemical size up using supplied charts
- Meter selection
- 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?
- Approach cautiously uphill, upwind
- Secure the scene
- Identify the hazard
- Assess the situation
- Obtain help
- Decide on site entry
- Respond
- 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?
- A baseline physical
- An annual physical
- An exposure physical
- An exit physical
Specific gravity
A way of expressing the weight of liquid and solids
viscosity
is the measure of thickness or flowability of a liquid at a given temperature
Anhydrous
describes compounds that contain no water or crystals that lack chemically bound water of crystallization
fire point
is the minimum temperature to which a substance must be heated so it produces enough vapor to support sustained combustion
Anhydrous
means dry or without water.
hydrophobic
element that will repel water. example car wax
hydrophilic
absorbs water
Aggressive Materials
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:
Oxidizers
Temperature change
matter that can change it state from solid to liquid, liquid to gas and back again
boiling point
is the temperature at which the vapor pressure of a liquid is equal to the atmospheric pressure around the liquid.
what is the relationship between temperature and pressure?
they are both proportionately to one another
