# Safety Hazard Detection

## Overview
Computer vision-based detection of physical safety hazards on construction sites including open edges, unguarded openings, unshored excavations, blocked access routes, unsafe scaffolding, fire hazards, and hazardous material exposures. Primary agent: CV/IoT Integration Specialist.

## Steps
1. **Image Preprocessing** → Prepare camera frame or photo for analysis
2. **Scene Understanding** → Identify the environment type and current work activities
3. **Hazard Detection** → Analyse for hazards: open edges without protection, unguarded openings, unshored excavations, blocked access or egress routes, unsafe scaffolding, fire hazards, hazardous material exposures, falling object risks
4. **Severity Assessment** → Classify hazard severity: Low, Moderate, High, Critical
5. **Location Tagging** → Record hazard location relative to camera and coordinates if known
6. **Alert Generation** → Generate immediate alert for high or critical hazards
7. **Documentation** → Log hazard with evidence photograph for follow-up

## Success Criteria
- Hazard detection accuracy > 90% for defined hazard types
- Classification matches actual hazard severity
- Alerts generated for serious hazards without delay
- All detections documented with evidence

## Common Pitfalls
1. Similar objects → Temporary materials confused with hazards
2. Transient conditions → Temporary conditions detected as hazards
3. Camera coverage → Hazards in blind spots not detected
