landing zone info
- Landing Zone Officer should be designated; coordinates incoming aircraft operations with incident commander (IC) - selection of site: site prep, site protection and control, air-to-ground communications, updating IC on ETA
26
what does IC stand for?
incident commander
27
ideal condition of LZ
- ideally 100' by 100' w/ little to no slope - clear of visible debris or obstructions - if area is dusty, consider lightly watering area with fog pattern - don't point charged hose line at aircraft - mark LZ with cones (daytime) or strobes (nighttime) - avoid shining lights up towards aircraft - avoid using flares
28
strobes
"a light or lamp that flashes regularly and can make moving objects look like they're not moving or like they're moving very slowly"
29
flares

31
triage
"the preliminary assessment of patients or casualties in order to determine the urgency of their need for treatment and the nature of treatment required"
32
primary triage
used at the site to rapidly categorize patient conditions for treatment and transport needs
33
secondary triage
used at the treatment area where patients are triaged again - patients are labeled with tags to assign priorities
34
START triage
- 60 second assessment - assess ability to walk, respiratory effort, pulses/perfusion and neurological status
35
Step 1 of triage
ability to walk walk and understand basic commands = delayed
36
Step 2 of triage
respirations - absent respirations = dead - < 10 or > 30 = critical - normal respirations = delayed
37
Step 3 of triage
pulses/perfusion - absent pulse = dead - present at carotid and absent at radial = critical
38
Step 4 of triage
mental status alert and oriented? have patient perform motor task - patient who can perform both tasks = delayed
39
if patient does not have any serious injuries and is alert and oriented (triage)
hold
40
what color is delayed (triage)?
yellow
41
what color is dead (triage)?
black
42
what color is critical (triage)?
red
43
what color is hold (triage)?
green
44
hot zone (HazMat Zones)
site of contamination (marked in red)
45
warm zone (HazMat Zones)
contamination reduction zone (marked in yellow)
46
cold zone (HazMat Zones)
safe zone - no contaminants (marked in green)
47
what does LEL stand for (Tox terms)?
lower explosive limit
48
