SCP-187 only sees changes that are different than the norm in a given subject. The D-class personnel for instance are missing their legs, or have holes in their head for example. Containment door broken is different than the norm for a given SCP.

"Class D personnel are expendable personnel used to handle extremely hazardous anomalies and are not allowed to come into contact with Class A or Class B personnel. Class D personnel are typically drawn worldwide from the ranks of prison inmates convicted of violent crimes, especially those on death row. In times of duress, Protocol 12 may be enacted, which allows recruitment from other sources — such as political prisoners, refugee populations, and other civilian sources — that can be transferred into Foundation custody under plausibly deniable circumstances. Class D personnel are to be given regular mandatory psychiatric evaluations and are to be administered an amnestic of at least Class B strength or terminated at the end of the month at the discretion of on-site security or medical staff. In the event of a catastrophic site event, Class D personnel are to be terminated immediately except as deemed necessary by on-site security personnel."
