Arafed man in a white uniform and protective gear cleaning a hallway

Moved to Site-19 in 1993。The origin is still unknown。It is built of concrete and rebar，And there are traces of Krylon brand spray paint。SCP-173 is mobile and highly hostile。The object cannot move within direct line of sight。The line of sight with SCP-173 must not be interrupted at all times。People sent to the containment room should remind each other before blinking an eye。The object was reportedly attacked by breaking the neck at the base of the skull，Or strangulation。In an attack incident，Personnel should comply with Class 4 hazardous object containment measures。 Personnel report，When no one is present in the holding room，There will be the sound of scraping stones。This is considered normal，Any changes in this behaviour should be reported to the acting HMCL supervisor on duty。 The reddish-brown substance on the floor is a mixture of feces and blood。The origin of these items is unknown。The internal environment must be cleaned every two weeks。
