Steam Generator Pressure Release Valve
Most relief valves are rated for temperature and pressure situations. Check the specifications on your valve to see what the specifics are. I have never seen a code that allows the discharge to be in an "inhabited" area. Many say the valve must have piping to a maximum of 6" above the floor. Some codes require the piping to exit the building and not be in a position to harm anyone. In Florida, where I lived, the T/P valve had to exit the house and dump into a french drain. Your current situation is dangerous and could be considered life threatening. Probably against code also.
If you have never made a mistake, you haven't done much.
