ResponderOS puts the tools that actually matter on scene, mid-shift, and at the end of a long day in your hands without waiting for a department rollout. The individual plan includes five kits. No agency account. No procurement cycle. SceneKit: Field Operations Reference The job aids responders reach for on actual calls. PumpOps and fire flow calculators, foam concentrations, water supply math, ladder and ventilation references, a full rope rigging suite, trench and confined space tools, collapse operations, LZ setup, and hazmat/ERG lookup. ICS forms when you need them. Built around the calls that require you to do the math right, fast, without hunting through a binder on the rig. MedKit: Clinical Tools for the Field Provider Active clinical support for EMS and fire-based providers. Drug and drip calculators, overdose and toxidrome decision support, cardiac arrest management, airway and RSI reference, pediatric and OB tools, a full medication lookup, and clinical pearls for the differential that doesn't fit neatly. Built for the medic managing a critical patient, or the firefighter who needs the right dose before medical control picks up. CommandKit Lite: Incident Management for the Single-Unit Officer Lightweight IC tools for the officer running a working incident without a full command post. Unit tracking, sector assignments, and a patient log built around the rhythm of small-to-medium incidents, like the structure fire where you're command and entry at the same time, or the multi-patient MVC before mutual aid arrives. Not a replacement for ICS at a major incident. The tool for every other call. PersonnelKit: The Leadership Paper Trail The documentation that should exist for every evaluation, counseling session, and mentoring touchpoint, and almost never does. Structured prompts for the things that matter, a timeline of every interaction, and probationary tracking that fires reminders before the deadline, not on it. The kind of record that protects you and the person you're developing. TaskKit: One List for Everything You're Accountable For Personal tasks, supervisor-assigned work, delegation to direct reports, subtasks, and acknowledgement tracking. Built around the shift, not the workweek. What needs to happen before you go home, what you delegated and whether it was acknowledged, and what carries over. Task management designed for the 24-hour rhythm. More kits, including WellnessKit, LeadershipKit, and PlannerKit, are being adapted for individual use and will be included in your existing subscription at no extra cost when they ship. Built between calls by an active EMS Captain. Used every shift.
