- **Caution**: 

### Q: What are the main safety features of industrial observation windows?
**A**: Our observation windows feature tempered safety glass or impact-resistant polycarbonate panels, safety interlocks that prevent operation when open, and secure mounting frames with sealing gaskets for environmental protection.

### Q: Which material is best for high-impact industrial environments?
**A**: Polycarbonate observation windows offer the highest impact resistance, making them ideal for heavy machinery applications. Tempered glass provides excellent clarity and scratch resistance, while acrylic (PMMA) offers good chemical resistance at a lower cost.

### Q: How are observation windows installed in control cabins?
**A**: Observation windows are installed using mounting frames secured to the cabin structure, with sealing gaskets to prevent dust and moisture ingress. Safety interlocks connect to machinery controls to ensure safe operation during maintenance.
