I am interested in building a prop for an upcoming department wide Mayday training evolution. I am interested to see if anyone has any plans or experience in building the prop used to simulate a firefighter falling. I have seen this prop designed with a collapsible ledge and the firefighter falls down into a "pit" with safe materials to land upon. If anyone has any information, please let me know.

It's funny this comes up, we just did this for RIT training a month or two ago. We used a Tractor Supply Co. store that was vacant. We found a room in the store that was elevated about 4 feet off the cement floor. We cut a section out of the floor and attached a 2x4 to one side for extra support. We hinged the cut section on one side and attached a hinged support leg on the other side with an attached pull handle. This way when the crew began searching the room you could observe their progress, and pull the handle at the appropriate time dropping them through the floor. We found a mattress to soften the landing a little bit, and the prop was a success. Good luck with yours.

We have an "Entrapenator" built at our training facilities. It, like what you're looking for, is designed to make firefighters not only figure out how to get out of predicaments, but also the proper procedures to follow when doing so, such as proper mayday and LUNAR reports. One of the last obstacles in the Entrapenator is a collapse simulator. A firefighter crawls up an incline, and appears to be crawling on a level floor, when the floor he's on tilts and tumbles him down onto the ground. It's simply a cantilevered piece of plywood that only tilts once he's gone past a certain point.

Specs, no. We didn't have blueprints, we just built it out of plywood and 2x4's. To fit it into the space in the tower, it is U-shaped.
When you enter in, crawling and blacked out, you encounter a wall (a piece of plywood). The entrance through which you came is closed and locked, so you cannot get out of this space that is just barely long enough to fit in on hands and knees. Once you properly call a mayday, the wall in front of you slides up and you proceed.
The next obstacle is a crisscrossed mess of bungee cords and rope, with rafter-simulating studs on the floor. The object is to simulate an attic, with fallen duct work and wiring. You could easily substitute actual wire, which is cheap and easy to replace. This would have the added benefit of making firefighters use their tools to free themselves, and ensuring that guys will actually HAVE tools in the future. If you've ever been stuck in mattress springs or ductwork, you know how important a pair of cutters can be. Again, mayday is sounded, firefighter works to get free.
After this is a wall breach simulator, with household wiring and firestops. You could use whatever spacing is typical in your area for the studs, and could even put up drywall, since it's easy to screw on and off after each firefighter passes through.
Next is a collapse simulator that simulates a roof or floor collapse onto the firefighter. Basically, it's two pieces of plywood that hinge at the same point, so when they fall, they create a void. Mayday, plywood lifts, proceed.
The firefighter then climbs a set of stairs, hits a platform. The platform is a balanced piece of plywood that tips over after the firefighter proceeds far enough, dumping him down a couple feet onto a mattress. Mayday, and the wall at the end is lifted. The end.
