"by a set of air conditioners ,"
The comma should not be spaced, change this to:
"by a set of air conditioners,"
"Any spikes in temperature are immediately to be investigated and reported."
This sentence sounds a little off, here's my suggested change:
"Any sudden changes in the temperature of RPC-XXX's containment room is to be investigated and reported."
"automated fire extinguishers will switch on and put out the fire."
Switch does not sound very clinical, I suggest replacing 'switch' with 'activate'. If you make this change, remove the "on" right after it.
"should this fail, alarms and alerts are to be activated and MST Charlie-2 "Fire Fighters" mobilized."
Add a comma:
""should this fail, alarms and alerts are to be activated, and MST Charlie-2 "Fire Fighters" is to be mobilized."
"RPC-XXX may be accessed by all Level 2 Authority personnel (Excluding 2A personnel)"
Why only 2A personnel? I suggest adding a footnote elaborating on why only they cannot access it, unless you mean anyone below level 2A is not permitted to access RPC-XXX.
"Any attempt to extinguish the fire with water will only increase the size, strengthen the flame and extend its longevity."
Add a comma:
"Any attempt to extinguish the fire with water will only increase the size, strengthen the flame, and extend its longevity."
"RPC instances do spoil, but at a much slower rate than a regular Daucus carota"
Add a brief footnote saying "wild carrot" at "Daucus carota", and add //'s around it to indent it if you wish. Most articles do that.
"Discovery:RPC-XXX…"
Add a space between the discovery and RPC-XXX:
"Discovery: RPC-XXX"
"RPC XXX instances 1-12 were recovered by a Delta-4 "Garcas" field agent placed within the [REDACTED] Police Department."
Add a - at RPC XXX:
RPC-XXX instances 1-12 were recovered by a Delta-4 "Garcas" field agent placed within the [REDACTED] Police Department.
"A week after the discovery of RPC-XXX an explosion at a farm near [REDACTED], California occurred at around 6:30 pm, destroying the farmhouse and killing a family of six."
Add a comma:
"A week after the discovery of RPC-XXX, an explosion at a farm near [REDACTED], California occurred at around 6:30 pm, destroying the farmhouse and killing a family of six."
"After further investigation, four other instances of RPC-XXX were discovered in the destroyed house in the kitchen."
Replace 'discovered' with 'recovered', and replace "destroyed house in the kitchen" with "the decimated kitchen within the home."
I'm a person who really doesn't have super high standards, but these minor errors need to be fixed. I like this as it's one of those 'short and sweet' RPC / SCP articles, and takes me back to the classic days. Anyways, good luck with your future drafts and endeavors!
EDIT: The narrative is minimal, and I think a little more needs to be elaborated. How about an addendum listing all the incidents this RPC caused like in the discovery and Addendum 01?
