What is the primary safety concern when working with electric furnaces?

When working with electric furnaces, the primary safety concern is electrical shock. Electric furnaces operate using high voltage electricity to generate heat, which means there is an inherent risk of electrical shock if proper safety precautions are not taken. This risk is particularly important in the context of HVAC work, where technicians may be required to handle wires, connections, and components that can carry significant electrical current.

To mitigate the risk of electrical shock, it is crucial for technicians to follow safety protocols, including turning off the power at the main service panel before servicing the unit, using insulated tools, and wearing appropriate personal protective equipment.

While noise levels, heat dissipation, and carbon monoxide leaks are issues that may be associated with various heating systems, they do not present as immediate a safety risk as electrical shock does in the context of electric furnaces. Electric furnaces do not produce carbon monoxide since they do not rely on combustion, and while heat dissipation is a factor to consider, it does not carry the same direct danger of bodily harm as electrical shock.
