This Exam contains:

-Guarantee passing score -84 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: Describe which written documents should be prepared as a result of the critique.

Answer:

1: LERP and SOP/SOG

2: Site safety plan

3: Written elements of the plan of action

Question 2: What is a disadvantage of Solidification?

Answer:

Could pose additional problems when liquid contaminant increases in volume as it solidifies. If the liquid is in a container, when the solidifier is added, as the volume increases it may damage the container.

Question 3: What should safety briefings with entry and backup teams cover?

Answer:

1: Explain potential safety and health hazards

2: Cover objectives and tasks to be performed

3: Confirm designated radio channels

4: Hand and verbal emergency signals

5: PPE requirements

6: Location and layout of decontamination

Question 4: What is the purpose of Neutralization?

Answer:

To add a chemical to a contaminant, in order to change its chemical structure, with the goal of eliminating or rendering it harmless.Question 5: Safety considerations that should be addressed in the plan of action include.

Answer:

1: Analysis of the hazards and risk

2: Site map or sketch

3: Site work zones

4: Use of buddy system

5: Site communications

6: Command post location

7: SOP and safe work practices

8: Medical assistance

9: Hazard monitoring plan

10: Decon

11: Oth

Question 6: What are the disadvantages to Level C?

Answer:

1) The hazard has to be known, they protect only against specific contaminates.

2) Limited life of its filters and canisters.

3) Periodic monitoring of the air must be performed.

4) Can not be used in atmospheres with less than 19.5% oxygen.

Question 7: Define Resources in relation to IMS (Incident Management System)

Answer:

1: Tracks available personnel and equipment, kept at the staging area until assigned.

2: Coordinates functions with the Operations Officer

Question 8: What is a disadvantage of Disposal?

Answer:

Requires encapsulating the contaminated item(s) while being transported, in order to eliminate spreading vapour hazards posed by the contaminant.

Question 9: What is a disadvantage of Neutralization?

Answer:

The neutralizing chemical may not be readily available, which could pose a problem if time is of the essence in controlling the spread of the hazard.

Question 10: What is a disadvantage of Dilution?

Answer:

Some contaminants require an inordinate amount of diluting solution. Run-off must be collected and disposed of properly. Could create large quantities of diluted contaminated waste product, causing containment issues.

Question 11: Describe the key topics of an effective debriefing?

Answer:

1: Identity of materials

2: Signs and symptoms of exposure

3: Signs of critical incident stress

4: The duration of a recommended observation period for signs and symptoms

5: Medical contact

6: Safety and health hazards remaining at site

Question 12: What is the purpose of Chemical degradation?

Answer:

To let the contaminate degrade itself over time by allowing it to age.

Question 13: What is the purpose of Evaporation?

Answer:

Allow the contaminant to evaporate.Question 14: What factors must be considered in selecting the proper respiratory protection for a specified action option?

Answer:

1) Key is the level of protective clothing

2) Use highest level until levels of concentration have been determined.

Question 15: Give three examples of decontamination stations that can be established.

Answer:

1: Mass Casualty

2: Technical Decontamination

3: Emergency Decontamination

Question 16: What are the disadvantages to Level B?

Answer:

1) A non-encapsulating suit, with the SCBA worn on the outside.

2) The face piece serves as a barrier against chemical permeation for respiratory protection.

3) Can not be used when there is a high concentration of hazardous vapors or severe skin hazard

Question 17: What is the purpose of Vacuuming?

Answer:

To gather the contaminant by sucking it from the surface and placing it in a container.Question 18: NFPA 1991 requires what in regards to Level A (Vapor-Protective Suits).

Answer:

The NFPA 1991, Standard on Vapor-Protective Suits for Hazardous Chemical Emergencies, requires the manufacturer to provide documentation on a garment's permeation resistance for 3 hours.Question 19: What equipment is required for Level A:

Answer:

1) Pressure-demand, full facepiece, SCBA, or pressure demand air line respirator with escape SCBA.

2) Vapor-protective suit: totally encapsulating chemical protective suit (TECPS).

3) All components of a TECP suit should be IAW NFPA 1991.

Question 20: What is a disadvantage of Chemical degradation?

Answer:

Requires sufficient time for the material to degrade. Weather conditions must be favourable.
