Q

storage drums

A

barrel-like, can hold anything depending on barrel material

32
Q

storage bags

A

store solids and powders

33
Q

signal words to indicate relative toxicity of material
danger-poison:
danger:
warning:
caution:

A

danger-poison: highly toxic all routes of entry
danger: severe eye damage/skin irritation
warning: moderately toxic
caution: minor toxicity/eye damage/skin irritation

34
Q

storage carboys

A

transport corrosives in glass surrounded by wood

35
Q

storage cylinders

A

hold liquids and gases

36
Q

3 zones on a hazmat scene

A

hot: contamination zone for properly trained rescuers
warm: decon
cold: another buffer zone “clean” for medics

37
Q

difference between evac, rescue, and shelter in place

A

evacuation: removing/relocating people who may be affected
rescue: removing/relocating people already affected
shelter-in-place: keeping people inside

38
Q

different levels of hazmat ensembles

A

Level A: fully encapsulating and SCBA (direct responders)
Level B: level B - for respiratory not skin protection, not fully-encapsulating but air supply (decon)
Level C: for known substance, minimal splash protection and air purifying respirator (receivers of exposed patients and officers providing perimeter control)
level D: dust mask (cold zone)

39
Q

how harm caused by a hazmat is affected (4)

A

route of exposure
dose and concentration
how long toxin was in contact with body
if it exhibits delayed or acute toxicity

40
Q

primary vs secondary contamination

A

primary: direct exposure of patient to hazmat
secondary: hazmat transferred person to person or object to person

41
Q

4 primary methods of exposure

A

inhalation, ingestion, injection, absorption

42
Q

local vs systemic effect of exposure

A

local: localized (redness, pain, blisters)
systemic: damage occuring inside body

43
Q

what is the dose effect principle

A

the greater the length of time or the greater the concentration of the material, the greater the effect on the human body will probably be

44
Q

will liquids with high vapor pressure evaporate slower or quicker than liquids with low vapor pressure

A

quicker

45
Q

what is vapor pressure

A

liquids held inside a closed container will build pressure in the inner space above the liquid

46
Q

what 5 things affect evaporation rate

A

temperature of air and pavement, wind speed, shade, humidity, surface area

47
Q

what is vapor density

A

compares hazmat gas to air

48
Q

what is air’s vapor density

A

1

49
Q

examples of gases heavier than air

A

propane, butane, carbon dioxide

50
Q

examples of gases lighter than air

A

ammonia, acetylene, methane, hydrogen

51
Q

what is flash point

A

temperature at which a liquid fuel giving off vapors will ignite if an ignition source is present

52
Q

flash point of gasoline vs diesel

A

gasoline: NEGATIVE 45 degrees
diesel: 100-160 degrees

53
Q

liquids with low flash point have ___ vapor pressures

A

high

54
Q

what is ignition temperature

A

when a liquid fuel is heated beyond its ignition temp, it will ignite without external ignition source

55
Q

what is a flammable range and what are the two limits

A

fuel-air mixture necessary for chemical to burn properly must be within lower and upper flammable limit

56
Q

what is specific gravity of a chemical

A

whether it will sink or float in water

57
Q

threshold limit value

A

aka: permissible exposure limit
concentration of toxin a person can be exposed to for a 40 hour work week

58
Q

short-term exposure limit

A

concentration of a toxin to which a person can be briefly exposed for a max of 15mins four times a day

59
Q

lethal dose

A

single dose of toxin likely to be fatal

60
Q

lethal concentration

A

concentration of a toxin likely to be fatal

61
Q

immediately dangerous to life and health (IDLH)

A

atmospheric concentration of toxin posing immediate danger

62
Q

4 types of decontamination methods in the field

A

dilution, absorption, neutralization, disposal

63
Q

type of decon method using fluid to flush skin and eyes

A

dilution

64
Q

type of decon method using large pads to soak up liquid

A

absorption

65
Q

type of decon method using chemical to neutralize other chemical

A

neutralization

66
Q

which decon methods is almost always contraindicated and why

A

neutralization because the by-profduct reaction of acid-base produces heat

67
Q

type of decon method where you remove as much of patient’s clothing as possible

A

disposal

68
Q

what is considered the universal decontamination solution

A

water from whatever source is available

69
Q

where does the triage process take place in mass decontamination

after the decontamination corridor

71
Q

solvents and their symptoms

A

substance that can dissolve another substance

Q

what do pesticides interfere with in body

A

enzyme acetylcholinesterase

A

any gas that displaces oxygen from atmosphere
symptoms: interferes with use of oxygen at cellular level

74
Q

what is toxic products of combustion
