The wire is normally run above the box height.
A fire trap outlet used in motor homes. The wire self pierce romex conductors with a small contact friction contact. These should be replaced with quality screw terminal outlets in outlet boxes.
a shorted out outlet can cause a backfeed on the white wire, an open circuit on the white wire with and electrical appliance plugged in to an outlet can cause the same type of backfeed
The fan is probably a 115 VAC single phase fan and the outlet is probably a 230 VAC "two phase" outlet. The fan would then have the following wires: hot (black), neutral (white), and ground (green). The outlet would then have the following wires: hot #1 (black), hot #2 (red), neutral (white), and ground (green). Pick either of the two hot wires on the outlet and connect the hot wire of the fan to that (ignore the other hot wire on the outlet) and connect the neutral to neutral and ground to ground. If the wire colors are not as I described above you may have something else (e.g. 3-phase) and that would be wired differently, but those systems are usually used only in industrial settings not the home.
just leave the neutral wire as it is and connect the other two !!
it is Outlet that will work with 2 hot wire one black and white.

You don't.
See: "How can you re-wire a wall switch that controls an outlet to control a ceiling fan?" (Follow the link below.) The procedure is the same whether the new device is a light fixture or a ceiling fan.
Just make it a junction box. Remove the outlet, tie the blacks together under a wire nut. The the whites together under a wire nut. Tie the ground wires together under a wire nut. Push all the wires back into the outlet box and cover it with a blank cover. Paint the cover the same color as the wall. Do not sheet-rock over the outlet box. All junction boxes must be accessible.
If you are using proper authorised outlet boxes, they come with all the holes pre-cut. Holes to mount wire clamps and holes for mounting screws. If you don't use these you are not 'to code'

No, that is not unsafe.

They can be used if need be. But, know that all junction boxes must be covered and they must be accessible at all times. That can be placed above a drop ceiling with panels that can be removed but not above a permanent sheet rock or wood ceiling.
Ground wire is loose or disconnected somewhere in that circuit.
# 6 wire
You will need a receptacle that you can wire each outlet separately (not jumpered). You would then wire the switch in series on the line conductor with the outlet you want switchable. Wire the other outlet directly to the power source. You can jumper the neutral from one outlet to the other.
