Safety Info

A.U.FIRE is built for controlled, instructor-led training. It uses arm-only electrical stimulation to create a temporary muscle contraction so officers can practice staying calm, thinking clearly, and adapting under pressure.

Why administrators are comfortable with A.U.FIRE

  • Instructor-controlled: nothing happens unless the instructor activates it.

  • Arm-only use: designed for the arm (not the neck, chest, or head).

  • Short, scenario-based use: brief, purposeful activations tied to training objectives.

  • Stop anytime: trainees can pause or stop immediately, for any reason.

Who should NOT use A.U.FIRE

AUFIRE is intended for healthy adults in training. A trainee should not participate if they have:

  • a pacemaker, ICD, or other implanted electronic cardiac device

  • a known seizure disorder (unless cleared by a medical provider)

  • a serious heart condition (unless cleared by a medical provider)

  • pregnancy

  • a recent major arm/shoulder surgery or injury that could be aggravated by strong muscle contraction

If there’s any uncertainty, the simplest policy is: get medical clearance or sit out and still participate in the learning.

What A.U.FIRE feels like

  • A strong, brief muscle contraction in the arm

  • Temporary impairment during the scenario (instructor-controlled)

  • Some trainees may feel muscle fatigue afterward, similar to a hard workout

How a session is run

  1. Briefing: what it does, what it feels like, and how to stop

  2. Intensity can be modulated by the instructor from a very light buzz feeling to full muscle contraction 

  3. Controlled scenario use: short, purposeful activations tied to training goals

  4. Quick check-in: trainees confirm they feel normal before moving on

Instructors can choose to stop immediately if they observe or the trainee indicates

  • the trainee asks to stop (no questions, no pressure)

  • there’s unusual dizziness, nausea, or faintness

  • there is sharp pain (not normal muscle contraction discomfort)

  • any symptom feels “off” or unsafe

Training reality

AUFIRE exists because real encounters don’t come with a reset button. Controlled training that includes realistic consequences helps officers build the mental grip to keep solving problems under extreme stress.
