A specialized fine-tune of Gemma-3N focused on hazardous materials emergency response. This model combines ERG (Emergency Response Guidebook) protocols with atmospheric dispersion modeling capabilities similar to MARPLOT/ALOHA software.

Intended Use

Primary Applications:

Emergency response planning and training
Hazmat incident initial assessment
Chemical safety education
Plume dispersion estimation
UN dangerous goods classification assistance

NOT intended for:

Replacement of professional emergency response
Final decision-making in actual emergencies
Legal or regulatory compliance determinations

Training Data

Fine-tuned on:

ERG 2024 emergency response protocols
MARPLOT atmospheric dispersion models
UN dangerous goods classifications (UN1000-UN3500)
Chemical safety data sheets
Plume modeling scenarios

Dataset: Johnohhh1/erg_chemical_dataset (36,421 examples)

Capabilities

The model demonstrates knowledge in:

Chemical Identification: UN numbers, chemical properties, hazard classes
Emergency Response: Isolation distances, evacuation zones, PPE requirements
Atmospheric Modeling: Plume dispersion, dense gas behavior, stability classes
Complex Scenarios: BLEVEs, water-reactive chemicals, multi-chemical incidents
Decontamination: Procedures for various chemical exposures

Technical Specifications

Base Model: unsloth/gemma-3n-E4B-it (7.87B parameters)
Fine-tuned Parameters: 19.2M (0.24% of total)
Quantization: Q8_0 GGUF format (7.3GB)
Training: 1 epoch on 36,421 examples
Hardware: Trained on A100 GPU via Google Colab

Example Usage

With Ollama:

ollama run gemma-erg

Sample Prompts:

"What are the initial isolation distances for UN1005 (anhydrous ammonia)?"
"Calculate plume dispersion for 1000 gallons of chlorine in D stability conditions"
"What PPE is required for sulfuric acid decontamination?"

Performance

The model shows strong performance in:

Providing structured emergency response guidance
Calculating atmospheric dispersion estimates
Identifying chemical-specific hazards
Recommending appropriate PPE and decontamination

Limitations

Not a replacement for professional hazmat response
Atmospheric calculations are estimates requiring field validation
May not reflect latest regulatory changes post-training
Regional response protocols may vary from model recommendations

Safety & Ethics

⚠️ Critical Safety Notice: This model provides educational estimates only. Always defer to:

Local emergency response authorities
Professional hazmat teams
Official ERG documentation
Site-specific assessments
