Loved the ideas that you have here.
Ok Chief i have s MAYDAY prop that i have built for our fire district. that you use the fire hoses to do a maze with. and fall intoo a pit full of foam? will that work? email me at firstname.lastname@example.org if you want he pics and measurments. i have taught 14 stations in and out of our county on this important class. i also have a maze to.
the first one is the maze, the 2nd one is the MAYDAY PROP I built.
best idea is to have the denver drill dimensions
You should be able to find the details you need in one of the fire training resources available online here.
