Triage Under Surge After a Chemical Spill
At 15:20 a truck overturns on the highway 2 km from the ED, releasing an unknown industrial liquid. Within 20 minutes, 11 people arrive on foot, several with coughing, eye irritation, and chemical burns on their forearms. The waiting room is filling, and two patients are already in the department for unrelated complaints. The hospital has one decontamination shower, two isolation-capable rooms, and 6 nurses on shift. The incident commander has not yet identified the chemical. One patient is in respiratory distress with stridor; another is asymptomatic but was soaked in the liquid. Staff are asking whether to bring patients straight inside.
1. Establish the immediate scene and triage plan. Who gets decontaminated first, and how do you protect the department?

Scene control before patient care.
- Stop the inflow: station security at the entrance, direct arriving patients to a controlled staging area outside, and prevent contaminated patients from entering the waiting room. Notify the incident commander and the hospital emergency management lead.
- Personal protective equipment: staff entering the staging area need chemical-appropriate PPE (impermeable gown, gloves, eye/face protection, and respiratory protection per policy). Do not improvise with standard gloves.
- Decontamination: remove clothing (this alone removes most contaminant), bag it as hazardous waste, and irrigate skin and eyes copiously with water. Use the single shower in sequence; set up a secondary gross-decon area with hoses if needed.
Triage priority with one shower:
- First: the patient in respiratory distress with stridor - airway threat is immediately life-threatening, but decontaminate while protecting the airway (suction, oxygen, prepare for intubation).
- Second: patients with chemical burns and eye involvement - time-critical for irrigation to limit tissue damage.
- Third: the asymptomatic soaked patient - high risk from ongoing absorption and secondary contamination; decontaminate even without symptoms.
- Last: ambulatory patients with mild irritation who can wait in a separate area.
Department protection:
- Designate a clean/dirty line and a contaminated corridor.
- Close the waiting room to new walk-ins until the chemical is identified.
- Notify the two in-house patients' nurses that entry is restricted.
- Track staff exposures and document PPE use.
- Call poison control for agent-specific guidance once identified.
2. The chemical is later identified as a strong acid. Two nurses report skin tingling after helping a patient. Outline the exposure response and the documentation and reporting obligations.

Staff exposure response:
- Immediate decontamination: remove affected clothing, irrigate skin with copious water for at least 15-20 minutes, and flush eyes at an eyewash station if involved. Do not neutralize with chemicals.
- Medical evaluation: have both nurses assessed by a physician, document symptoms and exposure duration, and arrange follow-up.
- Remove from duty until cleared; do not let exposed staff continue patient care in contaminated PPE.
- Identify the source: review whether PPE was inadequate, whether the clean/dirty line was crossed, or whether the patient was under-decontaminated.
Documentation and reporting obligations:
- Incident report for each exposure with time, agent, task performed, PPE worn, symptoms, and treatment.
- OSHA-style recordable injury entry if criteria are met, per hospital policy.
- Employee health notification and workers' compensation process.
- Hospital emergency management and safety officer notification, since this is a hazardous materials event with staff injury.
- Public health/poison control notification for the chemical release, coordinated by the incident commander.
Operational follow-up:
- Reassess PPE stock and decon capacity; the single shower is a bottleneck.
- Debrief the team, review the clean/dirty line, and update the surge plan.
- Ensure remaining patients are tracked and that the two unrelated in-house patients were not exposed.
