What is TRACEMP and what does it stand for

It is the hazards faced at HAZ mat incidents, thermal, radiological, asphyxiation, chemical, etiological, mechanical, psychological

1

Alpha rays

Can be stopped by a sheet of paper, however can be dangerous if ingested or inhaled

2

Beta particles

Fast moving, can penetrate the skin, but are most dangerous when inhaled or ingested, can be reduced or stopped by a layer of clothing.

3

Gamma rays

High energy, very penetrating, can easily pass through the human body, several feet of concrete or a few inches of lead are required to stop.

4

X rays

Lower energy, single largest source of manufactured radiation exposure, less than an inch of lead can stop

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
