Transporter Biohazard Alarm — Unidentified Microbes in Riker

During an otherwise routine extraction, O'Brien's transporter console flashes a biohazard alarm: unidentified microbes have been detected in Commander Riker's tissue and the ship's biofilters cannot screen them. Geordi's precautionary retrieval request collides with an automated containment protocol, forcing the mission to pivot from a simple medevac to an urgent medical/containment problem. Riker downplays the injury, but the alert functions as a turning point—it escalates the stakes, notifies Dr. Pulaski, and sets up the experimental neural-diagnostic work to follow.

The narrative micro-steps within this event

3

Geordi orders an immediate beam-out, overriding Riker’s protest with first-contact caution. Safety protocol asserts control over Riker’s minimization.

dismissal to urgency

An alarm erupts at the transporter console as O’Brien reports unidentified microbes in Riker and confirms the biofilters can’t screen them. The expected extraction spirals into a biohazard threat.

Who Was There

Characters present in this moment

3

Alert, focused, and concerned about the implications of a contamination detection — prioritizing system protocols over haste.

O'Brien operates the transporter console in Transporter Room 4, inputs coordinates, reads diagnostics aloud when the alarm triggers, reports detection of unidentified microbes, and triggers the system's automatic notification to medical — professional and by-the-book while sounding the alarm.

Goals in this moment
  • Protect the ship and crew by preventing contaminated pattern transfer
  • Follow transporter safety procedures and diagnostic protocols
  • Inform medical and command so an appropriate containment/diagnostic response can occur
Active beliefs
  • Transporter diagnostics and biofilters exist to prevent biological contamination.
  • Ship systems and procedure must be trusted and followed even if it delays extraction.
  • A detected anomaly must be treated as a real threat until proven safe.
Character traits
procedural technically precise calm under pressure duty-bound
Follow Miles O'Brien's journey

Nonchalant on the surface, masking mild embarrassment and a stubborn reluctance to be removed from the mission.

Riker inspects a bloody calf wound, downplays the injury to Geordi, and reacts to the transporter's hold-up with light banter — minimizing the situation while remaining physically the subject of the diagnostic alarm.

Goals in this moment
  • Avoid being evacuated or made to feel like a liability
  • Return to the mission/continue the survey if possible
  • Maintain a calm, reassuring demeanor for the team
Active beliefs
  • The injury is minor and not worth interrupting the mission.
  • Crew members should not overreact to small wounds.
  • His presence on the surface is valuable and he can manage small injuries himself.
Character traits
stoic proud self-effacing resistant (to being fussed over)
Follow William Riker's journey

Controlled concern — outwardly calm and procedural but clearly anxious about infection risk and Riker's safety.

Geordi locates Riker, inspects the wound, and activates his handheld communicator to request an immediate beam-up; when the hold-up occurs he questions O'Brien and acknowledges the medical notification, maintaining protocol under pressure.

Goals in this moment
  • Secure immediate medical evacuation for Riker
  • Confirm the safety of the extraction and speed up the beam-up
  • Prevent further harm to his teammate by ensuring proper containment
Active beliefs
  • Unknown planetary hazards merit strict caution and protocol.
  • Prompt medical attention is the best course for an injured crewmember.
  • The transporter and ship systems can normally handle biohazards unless explicitly flagged otherwise.
Character traits
procedure-minded protective direct practical

Geordi's Portable Communicator (Handset)

Geordi's handheld communicator connects the planet surface to Transporter Room 4, carrying his beam-up request and allowing him to query O'Brien about the delay. The device is the dramatic bridge between the field and ship, making the transporter alarm audible to the away team and escalating the situation.

Before: In Geordi's hand, active and used for standard …
After: Still in Geordi's possession and in active use …
Before: In Geordi's hand, active and used for standard field communications.
After: Still in Geordi's possession and in active use as the conversation continues and the team acknowledges the medical notification.
Transporter Biofilter Module

The transporter biofilter module flags the unidentified microbes in Riker's pattern and fails to filter them out; its diagnostic reading is the technical trigger that converts a routine medevac into a containment and medical emergency, forcing pause and medical notification.

Before: Operational and monitoring the matter stream as a …
After: Shows anomalous diagnostics, unable to remove the detected …
Before: Operational and monitoring the matter stream as a background safety system within the transporter conduits.
After: Shows anomalous diagnostics, unable to remove the detected microbes, and has generated a biohazard alert requiring medical attention.
Transporter Control Console (Transporter Room)

The transporter control console is the locus of action: O'Brien inputs coordinates there, the alarm sounds from it, and it displays microbial detection readouts. Its alerts dictate procedure, inform the crew, and force a rapid reassessment of the beam-up.

Before: Energized, awaiting input, with normal operational indicators.
After: Active alarm state with red diagnostics displayed and …
Before: Energized, awaiting input, with normal operational indicators.
After: Active alarm state with red diagnostics displayed and the beam-up held pending medical direction.
Transporter Room Communication Panel

The nearby transporter room control panel flares and emits the alarm tone that punctuates the room, broadcasting the biohazard condition; it functions as the audible/visual confirmation of the biofilter's failure and drives immediate action from the technicians.

Before: Idle with normal lighted readouts and tactile switches …
After: Flashing red alarm state, emitting warning chimes and …
Before: Idle with normal lighted readouts and tactile switches in ready state.
After: Flashing red alarm state, emitting warning chimes and requiring technician acknowledgement and procedural response.

USS Enterprise Transporter Room 4

Transporter Room 4 serves as the extraction point and containment threshold where diagnostics are read and decisions are made; the room transforms from routine operational space to a focused control center managing a potential biological threat, crowding consoles and technicians around an alarming readout.

Atmosphere Tense, clinical, and alert — a procedural hush punctuated by alarms and terse, technical exchanges.
Function Operational hub and containment decision point for the attempted medevac and subsequent biohazard response.
