What hazards could be produced when a hydrovac is used to expose an electric cable?

Hazards of using a hydrovac to expose an electric cable include the risk of damaging the cable leading to electrical shock or power outage, potential for water seeping into the cable causing short circuits, and the risk of the hydrovac operator coming into contact with the electrified cable resulting in injury or fatality. It is essential to follow proper safety protocols when using a hydrovac near electrical cables to mitigate these hazards.
