Flashcards in Hazardous Materials Book Deck (43):
1

What are the primary functions of the hazmat IC structure?

Operations
Planning
Logistics
Finance/Administration

2

Who bears all responsibility of managing the incident

Incident Commander

3

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

4

Who dictates that a hazmat incident must be operated with an incident management system (IAP) in place?

OSHA and EPA

5

When was the use of NIMS implemented and mandated?

2003

6

If other positions of responsibility are not needed, who will assume those duties?

IC

7

If the section of the structure go unassigned, who will have responsibility?

IC

8

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

9

Is the Unified Command structure the most efficient and safest means of operation?

Yes

10

What is the concept of a Unified Command?

All agencies that are functionally involved in the Incident contribute to the process

11

What is the purpose of a Unified Command?

To help determine strategies and overall incident objectives and help plan jointly for tactical objectives

12

In the US structure, who directs the IAP?

Operation Section Chief

13

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.

14

What are the responsibility of the Hazmat Branch?

To manage all tactile operations carried out within the control zones

15

What does the Hazmat Branch manage?

Site Safety
Rescue
Entry Operations
Decon
Containment and Confinement
Sampling medical monitoring

16

What does the NFPA recommends?

the use of risk base response to hazmat incidents pr emergencies

17

What two factors does NFPA evaluate when utilizing the risk management matrix?

severity and probability

18

The severity of a chemical hazard focuses on what four areas concerning the hazard?

Health
Fire
Reactivity
Radioactivity

19

What is the Eight Step Process?

It is the tactical decision making model that focuses on Hazmat/WMD incident safe operating practices

20

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
7. Decontamination
8. Terminate the incident

21

What is HazmatIQ?

a four step process decision making response model that is used by major fire and law enforcement agencies in the US

22

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

23

What does DECIDE response model stand for?

Detect, Estimate, Choose Response, Identify, Do best option, Evaluate progress

24

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
7. Respond
8. Above all, do not assume

25

What action are taken during Nonintervention?

Allows the incident to run its course

26

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.

27

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.

28

What is the Medical Surveillance plan?

Consists of medical monitoring. should start far before the incident.

29

Who is the Medical Surveillance plan required by?

OSHA 29 CFR 191.120.

30

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

31

Specific gravity

A way of expressing the weight of liquid and solids

32

viscosity

is the measure of thickness or flowability of a liquid at a given temperature

33

Anhydrous

describes compounds that contain no water or crystals that lack chemically bound water of crystallization

34

fire point

is the minimum temperature to which a substance must be heated so it produces enough vapor to support sustained combustion

35

Anhydrous

means dry or without water.

36

hydrophobic

element that will repel water. example car wax

37

hydrophilic

absorbs water

38

Aggressive Materials

use when referring to corrosives and oxidizers. Will react with spill control products such as saw dust or other cellulose bases

39

Bases (or Caustic)

are materials that produce hydroxide ions when dissolved with water

40

Halogens, organic compounds and peroxide salts are examples of:

Oxidizers

41

Temperature change

matter that can change it state from solid to liquid, liquid to gas and back again

42

boiling point

is the temperature at which the vapor pressure of a liquid is equal to the atmospheric pressure around the liquid.

43

what is the relationship between temperature and pressure?

they are both proportionately to one another
