Should a firefighter snip MC cable or Romex wires?

The most prudent approach when dealing with MC cable or Romex wires is to ensure the power is off before cutting or snipping these types of electrical wires. When firefighters encounter these wires during emergency operations, safety is of paramount importance.

Cutting into live wires can result in severe electrical shock, fires, or equipment damage. Only after verifying that the electrical system is de-energized can firefighters safely snip these wires, reducing the risk of harm to themselves and others on the scene. This practice underscores the importance of assessing the circumstances and ensuring that safety protocols are followed before taking any action involving electrical components.

In addition, while there might be situations that justify cutting wires (such as when they pose an immediate threat), those situations still require confirmation that power is off to avoid unnecessary risks. This rationale aligns with the training and recommendations provided to emergency responders regarding handling electrical hazards effectively.
