Overview#
The Chemical Register domain implements a hazmat lookup and first responder guidance system for PSAP dispatchers. It provides instant access to chemical identification, hazard assessment, response procedures, and dispersion modeling parameters from authoritative data sources including CAMEO Chemicals, PubChem, and ERG.
Key Features#
- Chemical search and autocomplete by name, CAS number, UN number, or common names with relevance scoring
- Firefighting procedure guidance with extinguishing agent recommendations and water reactivity checks
- Acute Exposure Guideline Levels (AEGL-1/2/3, IDLH) for dispersion modeling integration
- PPE requirements with exposure-level specific respiratory, skin, eye, and glove protection recommendations
- Chemical-aware plume modeling with evacuation zone generation and geofence integration
- Multi-chemical reactivity matrix and combined hazard assessment
- Role-specific DO/DON'T checklists and step-by-step standard operating procedures
- First aid instructions and spill response guidance with isolation distances
Use Cases#
- PSAP dispatchers providing immediate hazmat guidance to first responders
- Firefighters accessing real-time chemical safety data during hazmat incidents
- Emergency managers calculating evacuation zones using dispersion modeling parameters
- Multi-chemical incident assessment with reactivity and combined hazard analysis
Integration#
Integrates with dispatch, geofencing, and alert domains for end-to-end hazmat incident response. Supports dispersion modeling services for evacuation zone calculations.
