A massive forest fire has been burning in the Tonto National Forest for over two weeks. Two fire jumpers team A radio to fire engine command truck B that they are behind the fire lines and trapped on the main hill by fire and smoke. Fire jumpers A advise they are being consumed by heavy white smoke and they are having difficulties breathing and are in desperate need of oxygen.
Team A tells command B they cannot last much longer and may succumb to smoke inhalation. Team A firemen also asks command B to tell their families they love them and goodbye. The command B incident commander looks on his GPS and map and asks A if they can walk 1,000 yards to the bottom of the mountain where there is a fork in the road. Fire jumpers A look through their binoculars and reply that they know where the fork in the road is but they cannot chance it because the fork is the main source of smoke which they have been trying to avoid.
Command B tells A the fork in the road is the only way to make a rescue attempt. B also says he is sending three additional fire jumpers in fire rescue truck C. He also tells A that rescue truck C is equipped with a 360-degree Anti-Carcinogenic Air Force- Field- Smoke System. B says that according to his GPS, truck C can reach them in 15 minutes. A says they are moving towards the smoke now and they should make it there in about 15 minutes but they will probably be unconscious or dead if rescue truck C is not on time.
Fire rescue truck C has a three-man crew. The truck captain tells his crew that at maximum PSI, truck C can push out air for about 8 minutes of continuous 360-degree AIR FORCE- FIELD COVERAGE. He also tells his crew they will conserve the air pressure and will only use it if necessary because they are all out of portable oxygen (*note - fire jumpers are not usually equipped with oxygen tanks).
Truck C and the rescue crew drive towards the fork in the road to rescue fire jumpers’ A. However, when they are about three minutes from the fork in the road a very thick wall of white smoke emerges and begins to engulf fire truck C. The captain who is driving truck C can’t see out the front or side windows of truck C.
To compensate, the captain only turns on the front vent export system, (below the front windshield) the two-side crew cabin vent export system, (below the side cab windows) and the top crew cabin vent export system (directly over the driver cabin roof) which forms a partial air Force-Field smoke barrier around the crew cab portion of the truck C. The captain also sets the PSI to 15% to conserve air which may be needed to rescue fire jumpers A.
After the system is activated, there is more visibility and rescue truck C makes it to the rendezvous point. Truck captain C is unable to reach fire jumpers A on the radio and they are not able to see well due to the smoke. However, because some of the smoke has been displaced by the thrust of the system, one crew member spots fire jumpers A who are both lying on the ground and appear to be unconscious. The two crew members exit truck C and are able to lift the two unconscious firemen aboard rescue truck C. As rescue truck C travels back down the mountainside a very heavy cloud of white smoke begins to cover the truck.
This smoke is about three times as thick as the first blanket of smoke and the GPS shows that rescue truck C is still five minutes away from command post B. Captain C is driving and cannot see anything in front of the truck. Due to the heavy smoke rescue truck C starts to stall and smoke begins to enter into the cab. Truck captain C radios command station B and tells them they are in extreme danger and they are now activating their 360-degree Anti-Carcinogenic Air-Force-Field Smoke System at maximum thrust. Once rescue truck C is activated at 100% PSI a 360-degree force field of air fully surrounds and protects the entire truck, causing the smoke to push away from rescue truck C and forming a clear sphere of clean air around, on top and beneath the truck. Rescue truck C is able to make it to the command area B and all of the fire heroes survive.
