What does the term "live saw" refer to?

The term "live saw" refers to a saw that is running, indicating that the saw is operational and actively engaged in cutting. This terminology is commonly used in firefighting and rescue operations, particularly when dealing with tasks that involve cutting materials such as wood or metal during emergencies. Recognizing a "live saw" is crucial for safety, as it signifies an active tool that can pose a risk of injury if not handled properly. Understanding this context helps ensure that firefighters maintain appropriate safety measures when using power tools during rescue operations or firefighting activities, as a running saw can be hazardous if approached without caution.
