This configuration causes most ground currents to cancel, reducing shock hazards and interference with communication lines.

The wiring in some of them may be improperly located, allowing the handle tube to cut it, and lead to an electric shock hazard.

This would disconnect when the radio was opened, and so prevent a shock hazard.

An exposed banana plug can present a shock hazard if connected to an energized source.

However, because third rail systems present electric shock hazards located close to the ground, higher system voltages (above 1,500 V) are not considered safe.

This condition can create a shock hazard if the defects are not corrected at the factory.

These imperfections may seem minor but they could bleed electricity from the wire and cause a shock hazard.

This is known as the "let go threshold" and is a criterion for shock hazard in electrical regulations.

However, the shock hazard of having only one end of the shield grounded must be evaluated for the risk.

Such a situation poses an electrical shock hazard and potential fire danger; an electrician should be consulted immediately.
