Yes…You can loose your shirt if you cut thru a cable…especially fiber optic cable. And I’ve seen power cables take the teeth right off an excavator bucket. Calling before you dig don’t guarantee you’ll not hit a cable, but will C.Y.A. (cover yer arse) if you hit one in an unmarked area.
You know one of the strangest one’s I’ve seen was when our plow crew hit a city water main while doing a road bore. Maps showed the main down at the 4’ depth…they hit it at 17”. Filled the manhole so fast everyone got wet. Came up thru the street and lifted a car off the tires. Amazing stuff water.
