- No OSHA Compliance: The hydrotherapy room where the first victem attempts (and fails) to commit suicide by boiling himself alive has no safeguards against people being boiled alive in the hydrotherapy tank, has a bunch of weights just lying around on the floor, and neither any of this equipment or the room itself is secured or locked in any way when not in use. In fact, the door can only be locked from the inside using a sliding latch. The room is also much larger and much creepier than it needs to be.
