## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: How does a laser safety scanner protect machinery operators?
**A**: The scanner projects laser beams to create invisible protective fields around hazardous machinery areas. When an intrusion is detected, it immediately triggers safety responses like machine shutdown or alarms to prevent accidents.

### Q: What are the key components in a laser safety scanner BOM?
**A**: The bill of materials includes a control unit for processing signals, a laser emitter to create the safety field, a protective housing (typically aluminum), and a receiver sensor that detects beam interruptions.

### Q: Why use optical glass lenses in laser safety scanners?
**A**: Optical glass lenses provide superior clarity and durability for precise laser beam projection and reception. They maintain accuracy in industrial environments with dust, vibrations, and temperature variations common in machinery manufacturing.
