What safety consideration is crucial when performing brazing with torches?

Proper ventilation is a crucial safety consideration when performing brazing with torches. When heat is applied, various gases and fumes can be released from the materials being joined. These fumes can be hazardous to health, potentially causing respiratory issues or other health problems if inhaled in considerable amounts. Ensuring adequate ventilation helps to disperse these potentially harmful fumes, creating a safer working environment.

While wearing gloves and a face shield are important safety measures, they primarily protect against burns and eye injuries, respectively, rather than the inhalation of harmful substances. Controlling the flame is essential for preventing accidents and managing the brazing process itself, but it does not address the air quality issues that arise during brazing. Therefore, ensuring proper ventilation stands out as the most critical aspect of safety in this context.
