What is the purpose of using exhaust fans during torch operations?

Using exhaust fans during torch operations is crucial for maintaining a safe working environment by effectively drawing away harmful fumes and gases generated during the process. When torches are used, various toxic fumes can be released, including those from burning materials or off-gassing. The primary purpose of the exhaust fans is to mitigate these risks by ventilating the area, ensuring that dangerous concentrations of fumes do not accumulate. This helps protect workers from potential inhalation hazards that could lead to health issues.

Additionally, while improving visibility, providing air conditioning, or increasing temperature might be considerations in other contexts, they do not address the primary safety concern of air quality during torch operations. Hence, focusing on the removal of hazardous fumes is paramount, making the correct choice essential for safe torch operation protocols.
