"If something goes wrong inside of a building, then how can a fellow group of firefighters go in a rescue that team," says Captain Brad Burns with the Siloam Springs Fire Department.
But don't worry--it's all just a training exercise inside this house.
"We're using a smudge pot to smoke it up and we're using mayday drills and rapid intervention teams," says Burns.
Firefighters from all over Northwest Arkansas -- learning more about their job with a group called the Natural Fools.
"We hope they never have to use it. That's the objective of training--that they don't get caught in that scenario and have to use these skill sets."
And everything they learn Saturday is off the clock.
"Every person here is here of their own free will they're not getting reimbursed."
But simulations like these are getting harder and harder to come by.
"This kind of training here is first of all is invaluable because it's tough right now to get acquired structures."
Captain Brad Burns with the Siloam Springs Fire Department says about 80 percent of calls are medically related these days. So for new recruits, finding fires to fight is the hard part.
"It could be quite some time before they actually, outside of their basic training, get an actual fire."
So first responders without a lot of experience are thankful for the new opportunity.
"Firefighters have a sense of debt, even though they are servants, they do owe the community a certain level of readiness and preparedness so everybody sleeps better at night when the alarm goes off."
