Q

What level must the safety officer be trained to on a HAZ mat incident

A

The level of operations

31
Q

What training must the IC of a HAZ mat incident have

A

Must have incident management training, and and be at the HAZ mat operational level

32
Q

Does a HAZ mat incident need an assistant safety officer

A

Yes

33
Q

What are the HAZ mat incident levels

A

Level 1, least serious and easy to handle, evacuation is limited to the area of the spill
Level 2, requires the service of a formal HAZ mat team example is a leaking tanker
Level 3, requires state and federal assistance, most serious incident, may require evacuation over large areas

34
Q

What release when a container fails

A

The product, energy, and the container

35
Q

What are the different levels of HAZ mat contact

A

Immediate, seconds
Short term, minutes or hours
Medium term, days or weeks or years
Long term, years or generations

36
Q

What are the three modes of operation when considering strategies on a HAZ mat incident

A

Non-intervention (awareness level), defensive (operational level), or offensive (technician level)

37
Q

What is the primary strategic goal for first responder at a HAZ mat incident

A

Isolation

38
Q

When does the erg table for initial isolation distances and protective action distance not apply

A

If the material is on fire, or has been leaking for longer than 30 minutes

39
Q

What is smallest isolation distance listed in the erg

A

100 feet

40
Q

What is the protection action zone?

A

The area immediately adjacent and downwind from the initial isolation zone

41
Q

What are the hazard control zones

A

Hot zone or exclusion zone, contaminated area or can become contaminated area (HAZ mat technicians)
Warm zone or contamination reduction area, area abutting the hot zone and extending to the cold zone and is considered safe for workers to enter without special protective clothing, Decon usually happens here
Cold zone or support zone, used to carry out all other support no PPE required, command post and staging located here

42
Q

What are the rescue risk classes based on in a HAZ mat incident

A

The hazard classifications

43
Q

What is adsorption

A

When a material sticks to the outside instead of being sucked into as is the case with absorption

44
Q

Where can you find which kind of foam should be used on a substance

A

In the orange guide number of the erg

45
Q

What are options for fire control

A

Controlled burn, exposure protection, withdrawal, extinguishment

46
Q

What do structural firefighting turnouts protect you from

Heat, moisture, and ordinary hazards associated with a structure fire

47
Q

What is permeation

A

When a chemical passes through a fabric on a molecular level

Q

What is Chemical degradation

A

When the characteristics of a material are altered through contact with a chemical

49
Q

What is penetration

A

When a substance enters an opening or a puncture in a protective material

50
Q

What is the highest level of protective clothing for HAZ mat responders?

A

Vapor protective clothing

51
Q

What does a closed circuit SCBA do

A

A material compound or system that holds by absorption or adsorption

56
Q

What are the EPA suit levels

A

Level A, highest level against vapors, mist, and particles,
Level B, requires SCBA and provides against splashes, provides little or no protection against chemical vapors or gases to the skin

58
Q

What is contamination

A

When people, animals or the environment are exposed to and come in contact with enough material to become a carrier

59
Q

When should a Decon plan be put in place

A

Before people enter the hot zone

60
Q

When should emergency Decon be conducted

A

Failure of PPE, accidental contamination of responders, heat illness suffered by responders in the hot zone, medical attention needed for other victims

61
Q

What does emergency Decon not take in to consideration

A

The impact on the environment or property.

62
Q

How does the DOT recommend that first responders attack fires involving explosives

A

Do not attack them, instead withdraw and let the fire burn.

63
Q

What does the erg recommend for most explosives

67
Q

Do you extinguish flames coming from a pressure relief valve?

A

Never.

68
Q

Where do you never direct hose streams in a gas leak

A

At the source of leak or safety device, icing may occur
