A catastrophic chemical leak at a nearby manufacturing plant has resulted in dozens of exposed workers who are currently self-transporting to the local community hospital. The triage nurse receives radio confirmation that these individuals have bypassed field decontamination. What is the correct chronological sequence of actions the nurse must take to manage this crisis? Arrange the following steps from first to last.
- 1Initiate the hospital's lockdown protocol to secure all entry points.
- 2Don specialized chemical-resistant personal protective equipment (PPE).
- 3Route the incoming vehicles and pedestrians to the external warm zone.
- 4Instruct the victims to remove all clothing and begin gross water decontamination.
- 5Perform disaster triage and provide stabilizing care in the internal cold zone.
Cevap
The correct sequence is to first secure the facility (lockdown), protect the staff (don PPE), manage the casualty flow (route to warm zone), neutralize the threat (decontamination), and finally provide medical care (triage in the cold zone).
In a hazardous materials (HazMat) mass casualty incident, the overriding principle is to prevent secondary contamination. The nurse must first prioritize facility protection by initiating a lockdown; if the hospital is contaminated, it becomes non-operational. Next, healthcare personnel must don proper PPE to protect themselves before interacting with the hazard. Once protected, staff route the contaminated victims to the warm zone, preventing them from entering clean areas. In the warm zone, physical decontamination (clothing removal and water irrigation) takes place. Only after victims are thoroughly decontaminated can they be safely moved to the cold zone for medical triage and stabilization.
