How it works
Three steps, seconds to a guide number.
-
1
Scan
Aim the camera at any placard. On-device text recognition reads the 4-digit UN number or hazard class in real time.
-
2
Identify
HazScan matches the number against the complete offline ERG 2024 database and pulls the correct guide.
-
3
Respond
Read isolation distances, hazards, and emergency response actions straight from the guide — on scene, no signal.
Features
Everything you need to identify and respond, built for the field.
Multi-scan mode
Capture multiple placards across several vehicles or containers in a single incident.
Placard class recognition
Identifies FLAMMABLE, CORROSIVE, OXIDIZER, EXPLOSIVE and other DOT hazard classes.
Complete offline ERG 2024
The full Emergency Response Guidebook ships on-device. Works without cell service.
Manual search
Look up any entry by UN number or material name when scanning isn't an option.
Scan history
Every scan is saved on-device so you can revisit prior identifications during an incident.
Built for the field
A tool that performs where the work happens — not where the signal is.
Works offline
The entire ERG 2024 database is on the device. Dead zones, tunnels, remote highways — it just works.
On-device processing
Camera recognition and lookups run locally. Nothing leaves your phone, nothing waits on a server.
No data collection
No accounts, no tracking, no analytics. Your scans and history stay on your device.
Built for speed
From placard to guide number in seconds, with a high-contrast dark interface made for fast reads.
