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
Briefing: what it does, what it feels like, and how to stop
Intensity can be modulated by the instructor from a very light buzz feeling to full muscle contraction
Controlled scenario use: short, purposeful activations tied to training goals
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.
