24
What do the colors indicate on the 704 diamond
Blue is health, red is flammability, yellow is instability, white is special hazards
25
What are the only two symbols authorized to be on the wet section of the 704 placard
Oxidizer symbol (OX) or the water reactivity(W with a line through it). Older placards may have the radiation symbol on them though.
26
What are the signal words and what do they mean
Caution, minor health effects Warning, moderate hazards Danger, highest degree of hazard, ca have deadly effects or explode when exposed to heat Poison, required in addition to danger when substance is highly toxic
27
What are the piping identification color codes
Yellow, high hazard material Green, low hazard liquid Blue, low hazard gases Red, fire suppression materials
28
Management priorities on a HAZ mat incident
Life safety, incident stabilization, protect environment and property
29
What is the most crucial aspect of controlling any incident
Implementation of ICS
30
What level must the safety officer be trained to on a HAZ mat incident
The level of operations
31
What training must the IC of a HAZ mat incident have
Must have incident management training, and and be at the HAZ mat operational level
32
Does a HAZ mat incident need an assistant safety officer
Yes
33
What are the HAZ mat incident levels
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
What release when a container fails
The product, energy, and the container
35
What are the different levels of HAZ mat contact
Immediate, seconds Short term, minutes or hours Medium term, days or weeks or years Long term, years or generations
36
What are the three modes of operation when considering strategies on a HAZ mat incident
Non-intervention (awareness level), defensive (operational level), or offensive (technician level)
37
What is the primary strategic goal for first responder at a HAZ mat incident
Isolation
38
When does the erg table for initial isolation distances and protective action distance not apply
If the material is on fire, or has been leaking for longer than 30 minutes
39
What is smallest isolation distance listed in the erg
100 feet
40
What is the protection action zone?
The area immediately adjacent and downwind from the initial isolation zone
41
What are the hazard control zones
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
What are the rescue risk classes based on in a HAZ mat incident
The hazard classifications
43
What is adsorption
When a material sticks to the outside instead of being sucked into as is the case with absorption
44
Where can you find which kind of foam should be used on a substance
In the orange guide number of the erg
45
What are options for fire control
Controlled burn, exposure protection, withdrawal, extinguishment
46
What do structural firefighting turnouts protect you from
Heat, moisture, and ordinary hazards associated with a structure fire
47
What is permeation
When a chemical passes through a fabric on a molecular level
48
What is Chemical degradation
When the characteristics of a material are altered through contact with a chemical
49
What is penetration
When a substance enters an opening or a puncture in a protective material
50
What is the highest level of protective clothing for HAZ mat responders?
Vapor protective clothing
51
What does a closed circuit SCBA do
Recycles the wearers exhaled gases
52
How far can a supplied air breathing apparatus go
300 feet
53
When do you wear an air purifying respirator
When the atmosphere is controlled and substances are completely understood, o2 levels are between 19.5 and 23.5, atmosphere is below IDLH conditions
54
What is a catalyst
A substance that influences a chemical reaction between or among other substances
55
What is a sorbent
A material compound or system that holds by absorption or adsorption
56
What are the EPA suit levels
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 Level C, splash protecting garment, and an air purifying device Level D, typical work uniform or street clothing
57
What is exposure
When people, animals or the environment come in contact with a hazardous material
58
What is contamination
When people, animals or the environment are exposed to and come in contact with enough material to become a carrier
59
When should a Decon plan be put in place
Before people enter the hot zone
60
When should emergency Decon be conducted
Failure of PPE, accidental contamination of responders, heat illness suffered by responders in the hot zone, medical attention needed for other victims
61
What does emergency Decon not take in to consideration
The impact on the environment or property.
62
How does the DOT recommend that first responders attack fires involving explosives
Do not attack them, instead withdraw and let the fire burn.
63
What does the erg recommend for most explosives
That all civilians and first responders evacuate a distance of 1 mile in all directions

How much can a handheld pressure vessel weigh
100 pounds
65
What is the primary objective in a flammable gas leak
Turn off the flow of gas
66
What do you need to attack a flammable gases or liquids fire
Continuous water supply
67
Do you extinguish flames coming from a pressure relief valve?
Never.
68
Where do you never direct hose streams in a gas leak
At the source of leak or safety device, icing may occur
69
What is the primary concern at combustible liquids fires
Protect exposure
70
What is the proffered method of transporting radioactive material
Rail car
71
What is volatility
A substances ability to become a vapor at a relatively low temperature
72
What is persistence
