Continuing in a series of strange things that I have seen while consulting at hospitals…
In a Type I or Type II construction type structure (which most hospitals are) you are not allowed to have any combustible structural supports, including wood coverings over floors.
Overhead lift equipment raises elevator equipment to this platform, which serves as an extended floor. Then they roll the equipment to the elevator machines. Wood platforms are not permitted.
Remember what I said… Equipment rooms are a huge source of non-compliance on safety issues. They are out-of-sight/out-of-mind and nobody is assigned to maintain them.
