1

What are some reasons for direct contamination

  • Poor site management practices
  • Use of incompatible protective clothing
  • Failure to identify potential safety problems
  • Running out of breathing air in the hot zone
  • Failure to decontaminate
  • Fires in occupancies where hazardous materials may be stored or discarded
  • Fires in Clandestine drug labs

2

List the training for Awareness Level

  • Recognizing potential for a hazardous material release, identifying isolation locations and managing the scene to keep potential for injury to a minimum.
  • Who may be a resource that might be able to control or mitigate the event
  • Non-Intervention mode of response.

3

What are the functions of Control Zones

  • Keep bystanders and unauthorized personnel from interfering with first responders
  • Resgulate the movement of first responders within the zones
  • Minimize contamination

4

List the units who will respond to a clandestine drug lab

  • A Pump
  • Haz 1 + HazMat response team (Officer + 3 technicians)
  • Haz 3 (Decon) Hazardous Materials Officer + 1 technician

5

What is the minimum O Concentration for safe working conditions?

19.50%

6

What gas is used by EFRS to Test LEL?

Pentane

7

How do you clean MX4?

When necessary

  • Wipe with soft clean cloth
  • No Solvents or cleaning solutions
  • Sensor Difffusion membrane free from debris
  • Clean sensor openings wih sofe clean cloth or soft brush

8

Transportation of Dangerous Goods in Canada is regulated by whom?

Transport Canada

 

9

The Hazardous Materials Information System (HMIS) PPE systems are identfied by which Letters

  • A-K
  • X

10

What information is required on an MSDS

  1. Product Identifcation & Use
  2. Hazardous Ingredients
  3. Physical data (state, boiling point, specific gravity etc)
  4. Fire & Explosion data
  5. Reactivity data (stability of hte material)
  6. Toxicological data
  7. Preventative measures
  8. First aid measures
  9. Preparation Information (source of info, phone #, Date etc)

11

What is the Protective Action Distance?

The downwind distance from teh actual spill/ leak within which prodective actions could be iimplemented

12

How might cross-contamination occur?

  • Contaminated victim comes into physical contact with a clean person or other exposure such as an ambulance
  • A bystander or site worker crosses into the hazard area or comes into contact with a contaminated object within the hazard area
  • A decontaminated responder re-enters teh decon area or inner perimeter and comes into contact wih a conaminated person or object

13

List the indicators of a possible Chemical Incident

  • Dead animals/ fish/ birds
  • lack of insect life
  • unexplained odors
  • unusual #'s of dying or soc people (mass casualty)
  • pattern of casualties
  • blsters/ rashes
  • illness in confined areas
  • unusual liquid droplets
  • different looking areas
  • low-lying clouds
  • unusual metal debris

14

What is CBRNE

Terrorist activities will most likely accomplished using a CBRNE device

 

  • Chemical
  • Biological
  • Radiological
  • Nuclear
  • Explosive

15

What are the two categories of terrorism

  • Domestic based
  • Foreign based

16

Define Terrorism

An act that is committed for a political, religious, or ideological purpose, objective or cause with the intenton of intimidating the public, therefore jeopradizing security.

17

Explain the roles and responsibilities of operations level responders

  • Protect nearby persons, property or the environment from the release
  • Defensive fashion
  • Contain the release from a safe distance, keep it from spreading and prevent exposures

 

18

Basic Incident Command of a HazMat event nicludes on of 3 operational modes.

  • Offensive mode
  • Defensive mode
  • Non-Intervention

19

What is the formula for Dosage hazard

Dose = Chemcial + Concentration + Time exposed

20

What is an Acute health effect?

The type of chemcial that the body can flush out

Duration of effect:

  • Seconds to days

Effects

  • Immediate
  • mild to intermediate
  • recoverable

21

Explain Chronic health hazards

The slow build up of a toxic substance in the body from repeated exposures

Duration

  • Months to lifetime

Effects

  • Delayed
  • Severe
  • Permanent

 

22

What are the benefits of Emergency Decontamination?

  • Quick response time
  • Minimize injury

23

What are the limiitations of Emergency Decontamination?

  • Quick fix only
  • May not remove all contaminants
  • More thorough decontamination will have to follow
  • Damages the environment

24

What are the guidelines for Deontamination

  • Decon must be set up before anyone enters the hot zone,including rescue operations
  • Anyone in contact with the material or inside the hotzone must be decontaminated
  • Decon set up at different levels depending on material involved and the size of spill or release
  • @ larger incidents HazMat team may require FF to set up decon
  • Any one becomes contaminated they must stay in the hot zone and be decon before coming out
  • Msut dress one level below what you are decon-ing
