Interesting way to train for small problems (that no one wants to do training for) using big scenarios:
School bus crash: scenario: bus rolled completely and is back on wheels (this way the bus is not damaged after training). have kids on floor, over seats, tangled up in each other. Have personnel untangle, package and get off bus, using door, emergency doors and windows. You can use 2-3 back boards at a time, and unpackage patients and use the same equipment for the next patients.
This type of scenario gie good training for multiple situations: Triage, Mass Casualty; and 1-2 patient accidents. (you just have 20-30 one to two patient groups at one time).
Everyone is trained in backboarding patients, and you get some good heavy training done (good for a couple of hours or all day.
Everyone is happy: those that want big scenarios and those that need little ones. at the debrief: tell everyone that participated that they all did 1-2 person accidents; and you will be surprised.
You can do the same type of thing with smoke inhalation, and carbon monoxide poisonings:
like an earlier poster said, use the high school students; or if you have a college in your response area use them: you can use them as patients, innocent bystanders, who always get in the way and drunk and annoying bystanders. Good training for how to deal with obnoxious family members or potentially threatening situations.
