5 What are three main types of bulk transport? • Rail

• Cargo (trucking)

• Intermodal (containers designed to be transported by rail, truck, and ship)

6 What is the most damaging kind of radiation? ionizing radiation

7 What does a highlighted entry in the ERG (yellow or blue section) indicate? That the material is toxic by inhalation and the user should immediately consult the green section for initial isolation and protective action distances. (Quick evacuation needed!)

8 What kinds of information does a monitoring device provide? kind of material, quantity, and/or concentration of hazmat

9 What are the primary types of monitoring devices used at hazmat incidents? • CGIs (Combustible Gas Indicators)

• pH papers

• radiation detectors

• detector tubes

10 What do GGIs monitor? Combustible Gas Indicators monitor

• concentration of a gas in the air

• percentage of the LEL of the gas

• parts per million of the gas in air

11 What materials does a four-gas monitor check for? • combustible gases – hexane or pentane

• oxygen

• carbon monoxide

• hydrogen sulfide

12 What do indicator papers such as pH papers generally check? Indicator papers indicate specific hazards such as oxidizers, hydrogen sulfides, and peroxides. Some can now indicate biohazards such as anthrax. pH papers indicate alkaline or acid levels.

13 What do Geiger counters indicate? Levels of alpha, beta, and gamma radiation present, as indicated by the number of ions present.

14 What is a personal dosimeter? Device worn to measure and identify a person’s exposure to a particular radiation.

15 What is a detection tube and how does it work? A detection tube is a glass tube filled with a substance that changes color when a particular gas or vapor comes into contact with it. Most useful when a specific chemical is suspected.

16 What are some drawbacks to detection tubes? • require a pump to draw in vapors

• takes time to show results

• tubes have a shelf life

17 Labels Every hazardous material is required to have

a label(s). The label usually corresponds to

a hazard class and are listed in the Hazardous

Materials Table Column 6.

18 Shipping Papers Shipping papers are intended to accurately

describe the hazardous material being

shipped, including its possible hazards.

Shipping papers also identify all parties

associated with the material

50 Which of the following items will provide minimum shielding from gamma radiation? Several inches of lead

51 Under federal regulations, medical surveillance is required for Members of hazardous materials teams only

52 Biological monitoring measures The amount of an agent in your body

53 Simple asphyxiants displace oxygen in the air. Chemical asphyxiants Prevent the body from using inhaled oxygen

54 Etiologic means that an agent is Infectious

55 Which of the following organs is considered the primary “transfer point” for chemicals in

the body? The lungs

56 Which of the following statements is true regarding the hazard identification phase of

pre-incident planning? Transportation routes as well as fixed sites should be identified.

57 What influence does topography have on the spread of a poisonous gas that is heavier

than air? It may either increase or prevent the spread of the gas.

58 Which of the following is not true regarding weather conditions? Cold temperatures have little effect because of physical demands in fire


59 The hazard identification phase of pre-incident planning primarily involves Gathering information

60 Facilities that use only very small quantities of hazardous materials May not need to follow government reporting procedures

61 What is the next step in a pre-incident plan once you have collected all pertinent information? Develop a comprehensive plan of action

62 If after preplanning a facility, you find you would not have sufficient resources to respond

to an incident, your department should Take preventive measures
