Which of the following is a disadvantage of using cutting torches?

The choice that highlights a disadvantage of using cutting torches is significant because cutting torches indeed produce a considerable amount of slag during the cutting process. Slag is the molten material that is ejected when the metal is heated and cut by the torch. This can create additional cleanup work and can pose hazards on the scene, such as slipping risks or obstructing access. The presence of slag can complicate the rescue operation, making it more difficult for responders to maneuver around the area and increasing the time needed to complete a cut effectively.

In contrast, while cutting torches can be relatively slow in some applications and may require skilled operators for safe and efficient use, the accumulated slag is a specific and clear operational concern that can significantly impact the effectiveness of the rescue operation. Maintenance costs for cutting torches can vary, but they are generally not as pronounced as the operational challenges posed by slag production. Therefore, the excessive slag generated is a noteworthy disadvantage in the context of vehicle rescue scenarios.
