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


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.


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


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


What is the minimum O Concentration for safe working conditions?



What gas is used by EFRS to Test LEL?



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


Transportation of Dangerous Goods in Canada is regulated by whom?

Transport Canada



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

  • A-K
  • X


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)


What is the Protective Action Distance?

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


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


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


What is CBRNE

Terrorist activities will most likely accomplished using a CBRNE device


  • Chemical
  • Biological
  • Radiological
  • Nuclear
  • Explosive


What are the two categories of terrorism

  • Domestic based
  • Foreign based


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.


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



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

  • Offensive mode
  • Defensive mode
  • Non-Intervention


What is the formula for Dosage hazard

Dose = Chemcial + Concentration + Time exposed


What is an Acute health effect?

The type of chemcial that the body can flush out

Duration of effect:

  • Seconds to days


  • Immediate
  • mild to intermediate
  • recoverable


Explain Chronic health hazards

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


  • Months to lifetime


  • Delayed
  • Severe
  • Permanent



What are the benefits of Emergency Decontamination?

  • Quick response time
  • Minimize injury


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


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


What is involved in the T- Termination?

  • Decontamination
  • Rehabilitation
  • Post incident analysis
  • Medical screening


List some sources of A- Assistance

 What is usually the best protective action?



When is sheltering in place not effective?

  • Flammable vapors are present
  • The building cannot be closed tightly
  • Toxic gas will take a long time to clear


What types of Environmental damage can be experiencesd

  • Soil contamination and crop damage
  • Destruction of soil microorganizms
  • Damage to wildlife or domestic animals
  • Entry into the food chain of the chemical


What elements must be considered in a rescue strategy?
