⚠ MANDATE
AT LEAST 3 PERSONNEL MUST BE VIEWING SCP-173 AT ALL TIMES TO PREVENT A CONTAINMENT FAILURE.

SCP-173 has been relocated to Armed Research Area - Falcon in 20██. Its origin remains undisclosed at present. The entity is primarily composed of concrete and rebar, with detectable traces of Krylon brand spray paint. Notably, SCP-173 displays signs of animation and exhibits an exceedingly hostile disposition. It possesses the ability to move, but only when it is not within the direct line of sight of observers. Consequently, at no point should the line of sight be broken with SCP-173. Personnel assigned to interact with the containment chamber are strictly instructed to communicate with each other before blinking, to ensure continuous visual contact. The entity is known to employ two methods of attack: snapping the neck at the base of the skull or employing strangulation. In the event of an attack, personnel must diligently adhere to Class 4 hazardous object containment procedures for their safety and that of the facility.
