If smoke is seen coming from an electric control device, what is the first action to take?

When smoke is observed coming from an electric control device, the immediate and most critical action is to shut off the power to it. This step is essential for several reasons. First, cutting the power prevents further electrical flow, which could inadvertently increase the risk of a fire or damage to equipment. It also safeguards personnel from potential electrical hazards that could arise if they attempt to address the issue without first ensuring that the device is de-energized.

Dealing with smoke emanating from electrical equipment can indicate overheating, short circuits, or other failures that can pose serious safety risks. By shutting off the power, workers enhance their safety and create a controlled environment for any further assessment or repairs that might need to be conducted once the device is safely deactivated.

The other options, such as calling for advice, looking for a wiring diagram, or throwing water on it, are not suitable as initial responses. Calling for assistance delays the necessary action and might not provide immediate resolution to a potentially hazardous situation. Looking for a wiring diagram doesn’t address the immediate danger and could lead to further hazards if the device is not turned off. Throwing water onto electrical equipment is extremely dangerous and could result in electrical shock or worsen the situation. Therefore, shutting off the power is the
