Q

What are the different atmospheres?

A
  1. Safe Atmosphere: No Hazard
  2. Unsafe Atmosphere: Once a hazmat is released from its container, and unsafe condition or atmosphere exists. If one is exposed to material long enough time form of either acute or chronic injury will often occur.

As the first arriving IC what are the 3 most important things to do at a hazmat scene?

A
  1. Deny Entry

28
Q

Site management can be divided into six major tasks:

A
  1. Assume command
  2. Ensuring safe approach and positioning of resources
  3. Establishing staging as a method of controlling arriving units
  4. Establishing an isolation perimeter around the incident scene,
  5. Establishing Hazard Control Zones to ensure a safe work area
  6. Sizing up the need for immediate rescue and implementing initial public protective actions(PPA)
29
Q

What are the objectives of “Command and Control”?

A
  • Assuming command
  • Confirm Command
  • Select a stationary location for the ICP
  • Establish a staging area

What are the objectives of Approach and Positioning?

A

Approach from uphill and upwind.

Look for physical hazmat clues (vapor clouds, spilled materials, birds not flying through clouds)

31
Q

What are the objectives of the Staging Areas?

A

The ideal staging area is close enough to the isolation perimeter to reduce response time significantly, yet far enough away to allow units to remain highly mobile the tactical assignments

32
Q

What are the objectives of the Isolation Zone?

A

The isolation perimeter is the designated crowd control line surrounding the incident scent to maintain the safety and security of the spectators and the responders.

33
Q

What should Hazard control zones be based on?

A
  1. Flammability
  2. Oxygen: Enriched VS Deficient
  3. Toxicity
  4. Radioactivity
34
Q

What are the mail elements of the Identification process?

A
  • Recognition: Recognize the presence of hazardous materials
  • Identification: Identify the hazmat involved and the nature of the problem.
  • Classification: Determine the general hazard class or chemical family of the hazmat involved.
35
Q

Harm can be categorized in which forms?

A
  • Thermal
  • Toxicity/poisons
  • Radiation
  • Asphyxiation
  • Corrosivity
  • Etiologic (Biological materials ie bacteria viruses)
  • Mechanical ie Fragments from BLEVE
36
Q
