Hot Work Safety
Master hot work safety: soldering and brazing temperatures, ventilation in confined spaces, fire watch responsibility, acetylene cylinder handling, oxygen equipment safety.
Key Takeaways
- Soldering: 600–900°F; brazing: 1,100–2,200°F; third-degree burns occur above 156°F
- Fire extinguisher must be within 35 feet of hot work, charged and accessible

The exam expects you to recognize fire hazards, understand ventilation requirements, handle equipment safely (especially acetylene), and know the fire watch responsibility. These are not abstract concepts—they're about protecting lives and property.
