Decontamination Station

What Is Decontamination Station?

A decontamination station is a designated work point within a decontamination line where contaminated personnel, PPE, tools, or equipment undergo a specific step such as gross contaminant removal, washing, rinsing, monitoring, or controlled doffing. Stations progress from more contaminated toward cleaner areas. Staffing, spacing, water flow, cleaning method, and equipment depend on the contaminant, PPE, weather, site layout, and incident decontamination plan.

Why Decontamination Station Matters on the Fireground

Spacing stations too close together, using the wrong nozzle pressure (too high and you damage PPE or blast contaminant into the air; too low and you don't actually rinse), or staffing a station with untrained personnel are the most common reasons decon becomes a bottleneck or fails to actually remove contamination. Getting station setup and staffing right determines whether decon moves at the pace the incident needs.

Field Procedures & Tactical Steps

1. Determine the number of stations needed: typically one gross decon and one technical decon for incidents involving a few personnel, with a second line of each added for larger patient volumes.
2. Use a pressure and spray pattern appropriate for the contaminant, PPE, and equipment, following the incident plan and manufacturer guidance.
3. Assign 2–4 trained personnel per station: a primary nozzle operator, a backup/support person, and ideally someone managing runoff and contaminated equipment staging.
4. Separate stations sufficiently to prevent overspray, runoff, or personnel movement from transferring contamination into cleaner areas.
5. Stage brushes, buckets of decon solution, and PPE doffing assist supplies at each station before operations begin, and designate which personnel will work at gross vs. technical stations so roles are clear before the first person arrives.

Common Context & Application

Station setup is part of the decon footprint prep — once the corridor location is chosen, the crew stages hoses, nozzles, and buckets at each station, charges lines to the correct pressure, and assigns trained personnel to each station before the first contaminated person approaches.
