Which additional safety precaution is essential when working with gas torches?

Ensuring proper ventilation is crucial when working with gas torches because gas torches can produce toxic fumes or heat that can accumulate quickly in enclosed spaces. Adequate ventilation helps to dissipate these fumes, reducing the risk of inhalation and preventing the buildup of flammable gases in the environment. This safety measure minimizes the risk of fire hazards and respiratory issues, making it a fundamental practice when using any form of gas-powered equipment.

While wearing gloves and masks may offer some level of protection, they are not substitutes for proper airflow, which addresses the core risks associated with gas torches. Additionally, using torches only indoors is unsafe, as it does not account for the potential hazards that can arise without proper ventilation. Thus, prioritizing ventilation is the most effective precaution to ensure a safe working environment while using gas torches.
