So I feel like the clinical tone is one of the main issues here with this piece. There are certain sections in the containment procedures and description that just feel off. I've listed them below. These can mostly be rectified by breaking up your sentences some with periods, and perhaps choosing an alternate method of phrasing.
Any staff affected by SCP-XXXX may transfer away from Site 11 with the permission of the Site Director.
SCP-XXXX is a Class-A nonharmful corporeal apparition that takes the form of Senior Researcher Richard Donaldson, who passed away on 9/12/1998.
SCP-XXXX is capable of phasing through solid matter, appearing to persons it chooses and eliciting a fearful response in most people that encounter it that is nonanomalous in nature.
The first incident, while short, does give a bit of personality to Donaldson's ghost, although I feel like it could be expanded upon greatly. This is the beginning of your narrative after all. From a literary perspective, this is where your inciting incident would occur and the beginnings of foreshadowing take place. Given Donaldson's motivations, you can make this pretty clear with some more symbolism. That's what I thought was going to happen with the fridge like Dr. Daniels ate Donaldson's sandwich once twenty some odd years ago and now he's come back to do the same thing to her. And then she dies? That part doesn't really fit in with the rest of the tone of this piece. It feels more lighthearted and somewhat silly, so the death doesn't really work for me.
The dialogue here feels a bit too heavy handed, and somewhat unprofessional mainly with Dr. Mubarak. I understand that laymen would refer to this entity as a ghost, but these people are Foundation researchers and would refer to the entity with something more scientific. Perhaps Mubarak uses the word 'corporeal apparition' with a sarcastic tone? Also the '*seen taking notes*' is generally implied given that this is an interview log after all. They are unneeded.
Further investigation into SCP-XXXX's reasons for manifesting should continue. If all of Donaldson's coworkers were massive pricks like him, I can get why he'd want to torment them in the afterlife. - Dr. Mubarak
This line is also very unprofessional. When conversing, surely they would call each other pricks and the like, but in-universe this is a professional report.
The ending is… okay, but the stuff leading up to it are what is really taking this away from being something impactful.
