Working safely with hydrogen gas during the synthesis of carbon nanotubes (CNTs) involves several precautions and best practices due to hydrogen's highly flammable nature and its potential health hazards. Here are some key safety measures:
### 1. **Proper Ventilation:**
- Ensure that the work area is well-ventilated to prevent the accumulation of hydrogen gas.
- Use fume hoods or gas cabinets where hydrogen is used or stored to allow for
