Classification and rationale of predefined hazards included in the virtual inspection site
| Hazard | Hazard type | OSHA category | Justification for inclusion |
|---|---|---|---|
| Missing guardrails | Fall hazard | Fall protection | Represents One of the most cited OSHA violations; highly visible from elevated drone views; critical for perimeter safety |
| Tripping hazard (rebar) | Trip hazard | Housekeeping | Simulates poor housekeeping – a common real-world hazard; easily observed in drone flyovers |
| Suspended load | Struck-by hazard | Material handling | Demonstrates critical awareness of crane operations; drone view offers effective hazard assessment of load movement |
| Electrocution risk | Electrical hazard | Electrical safety | Highlights proximity to energized equipment; supports visual risk detection in power zones |
| Rolling barrels | Caught-in hazard | Material storage | Represents unsecured material hazards that pose risks when rolled; relevant for area scanning |
| Missing rebar caps | Impalement hazard | Site preparation | Frequently overlooked hazard; excellent test of visual attentiveness from aerial angles |
| Continuous hammering | Ergonomic hazard | Overexertion ergonomic | Simulates prolonged vibration exposure; useful for assessing noise-related and ergonomic risks |
| Kickback (tool use) | Struck-by motion risk | Tool Use-PPE | Represents common tool-related accidents; visible operator animation aids hazard recognition |
| Heavy load lifting | Manual handling | Ergonomics-Lifting | Represents musculoskeletal risk; used to test participants’ interpretation of lifting scenarios |
