San Diego Gas & Electric said Thursday gas-line breaks are on the the rise and warned contracts to call before they dig.

In the third-quarter of 2014, SDG&E crews repaired damage to 50 natural gas lines, compared to 36 in the second quarter and 15 in the first quarter.

On Wednesday a construction crew accidentally ruptured an underground pipeline while digging at the intersection of India and West Date streets in Little Italy, forcing evacuations that lasted several hours.

“This increase in natural gas pipeline damage is a significant area of concern for SDG&E,” said Jimmie I. Cho, senior vice president of gas operations and system integrity. “This risk can be avoided by contractors — and homeowners — making the quick call to 8-1-1 to have the utility-owned lines marked for free.”

Contractors should call two business days in advance of their planned work, the utility said.

SDG&E also said that if you suspect a gas emergency, or have questions regarding a gas odor or carbon monoxide, immediately call 800-411-7343. Natural gas is flammable and even a spark can serve as an ignition source.
