FDNY CoF – Torch Operations (G-60) Practice Exam

In torch operations, the term "backfire" specifically refers to a sudden flame that blows back into the torch tip. This situation can occur when there is a disruption in the flow of fuel or oxygen, causing the flame to move in the opposite direction from where it is intended to go. This can be dangerous, as it may lead to burns or other injuries for the operator and may also necessitate immediate corrective actions to avoid further incidents.

Understanding backfire is crucial for safe operations, as it highlights the importance of maintaining proper torch operation and fuel flow. Recognizing and responding to the signs of a potential backfire can prevent accidents and ensure the safety of all personnel involved in torch operations, making it essential training for those handling such equipment.
