I have to ramp up to a height of around 36"-42" for a scene. This will not be a wheelchair accessible area. What kind of incline can I use that is still comfortable to most patrons? I may also make it narrow in parts on the way up to play on claustrophobia fears. On the way down I will probably hang stuff in the way to create darkness before the next scene. I was thinking about a 2/12 slope ramp? 1/12 seems flat and 3/12 might seem like your out for a hike. Has anyone ever used more lineal foot on the accent side of things and less on the descend or vice versa?
Well..that's one way to not pass your inspection.
Nationally, (although some get away with it) all ramps must be handicap accessible and have a 1 inch rise for every 12 inches. That's the regulation on a federal level.
Actors and chainsaws should scare patrons.
Steep ramps and the possibility of falling/injuries should not.
Stick with the 1/12 code to be safe and smart.
The only way you could get by without following code is if you have an alternate path around the obstacle or if it can be considered a piece of playground equipment that falls under the size specs that require inspection.
Stick to the code, and play it safe.
