Working with molten bronze requires strict safety measures due to its extreme heat (around 1,700°F/930°C) and potential hazards. Here are critical precautions:

1. Protective Gear: Wear heat-resistant gloves, a full-face shield, and flame-retardant clothing. Leather aprons and steel-toe boots provide additional protection.

2. Ventilation: Ensure proper ventilation to avoid inhaling toxic fumes released during melting, especially when using fluxes or alloys containing zinc.

3. Workspace Setup: Keep the area clear of flammable materials. Use a sand-covered floor to prevent molten metal splashes from spreading.

4. Proper Tools: Use dry, preheated tongs and crucibles to handle molten bronze—moisture can cause explosive steam reactions.

5. Emergency Preparedness: Keep a Class D fire extinguisher nearby for metal fires and a first-aid kit for burns. Never use water on molten bronze spills.

6. Training: Only experienced personnel should handle molten bronze. Beginners must work under supervision.

By following these precautions, you can minimize risks and ensure a safe bronze-casting environment.
