What should be done if a manhole cover is smoking and possibly energized?

In the scenario of a smoking and possibly energized manhole cover, the most appropriate action is to leave it alone. This is due to the potential electrical hazards associated with an energized manhole cover. Attempting to remove it can lead to severe electric shock or injury, as there may be live wires underneath the cover that could cause a fatal current to pass through anyone who touches it.

Additionally, covering it with a blanket may obstruct visibility and may not effectively neutralize the hazard; in fact, it could potentially trap heat and exacerbate the situation. Pouring water on the cover is also highly inadvisable, as water is a conductor of electricity, which could further increase the risk of electric shock.

By leaving the manhole cover alone, firefighters or relevant authorities can approach the situation from a safe distance and enable trained professionals, such as utility workers, to assess and address the electrical issue appropriately. Understanding the risks and prioritizing safety is crucial in emergency scenarios involving electrical hazards.
