Classify hazardous waste in the field.
Guided by EPA's RCRA characteristics —
ignitability, corrosivity, reactivity, toxicity.

02 / 03 · How a session works
One question at a time.
HazMind asks one question at a time. You answer what you observe, the tool handles the branching.
The flow
Describe the sample
Phase, color, and where it came from. Enough to pick the first test.
Run the test it asks for
pH paper, water solubility, flame, etc. One test, one answer, then the next question.
Get the classification
With every answer that led there, in order, kept as the record of the session.
The stop
Do not continue testing
An unsafe result ends the session. Everything answered so far is still kept.
- Liquid
- Non-aqueous
- pH 6
- Oxidizer: positive
What it screens for
Ignitability D001
Corrosivity D002
Reactivity D003
Toxicity D004–D043
03 / 03 · With an account
Keep every session you run.
A finished session is kept either way. Without an account there's no identity to look it back up by, so it only lives on the device that ran it. Signing in is what makes it yours.

Retrievable, not just stored
An account is the only way to pull a past session back up in the app.
On any device
Start on one phone, sign in on another, and your history is already there.
Your 250 most recent
Browsable in-app. Nothing past it is deleted — it's just not shown yet.
Your data, your call
Request a copy, request deletion, or opt out of research use.
Coming soon
AI voice assistant Soon
Ask and answer out loud. Run a whole session without taking your gloves off.
PDF & CSV export Soon
Take a session out of the app in a form someone else can file.
RCRA Codes & DOT Class labelling Soon
The codes and class that follow from your result, ready to carry onto your own label.
Unlimited history Soon
Every session you've ever run, not just the 250 most recent.
All of these land on the paid plan, voice included. Classification itself is never gated — every tier runs the same wizard and gets the same result.
