Continuing in a series of strange things that I have seen while consulting at hospitals…
No… this picture is not an optical illusion. That step between the floor and the sill for the doorway is a doosey.
It definitely is more than the maximum 8-inches height for a riser for existing healthcare occupancy, or 9-inches in height for a riser in Industrial occupancy.
As I’ve said over and over… Mechanical rooms often have many non-compliant safety issues that an astute surveyor can find.
In a situation like this, steps with riser that do not exceed 7-inches (for new construction) need to be installed to access this doorway. And, the steps cannot be made of wood.
