Facts

Decedent died when her house exploded after natural gas leaked from a failed Cobra brand flexible brass connector attached to her kitchen range. The record showed that sulfur compounds in natural gas corrode the phosphorous brazing used in such connectors, eventually causing separation and gas leakage. NI-Gas had actual knowledge for years that brazed Cobra connectors were hazardous because of this interaction and had warned some customers generally about pre-1968 connectors. Plaintiff alleged NI-Gas negligently failed to warn decedent of the danger posed by the connector in her home.

Issue

Whether NI-Gas owed decedent a common law duty to warn about the danger posed by a customer-owned brazed Cobra gas connector when NI-Gas had actual knowledge that sulfur compounds in its gas would corrode such connectors and eventually cause leaks. Also, whether NI-Gas' filed tariff eliminated or barred that duty-based tort claim.

Rule

Although a gas company ordinarily has no duty regarding customer-owned pipes, fittings, or appliances, that rule yields when the company has knowledge or notice of a leak, defect, or unsafe condition. Where a gas utility has actual knowledge that its gas, interacting with a customer's brazed connector, creates a danger not normally associated with the product and the utility has superior knowledge of that hazard, the utility owes a common law duty of reasonable care, which may include warning customers. A utility tariff controls only when it speaks to the specific duty or claim at issue and does not automatically abolish unrelated common law tort duties.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

In Joliet, Meadow Vale Gas supplies odorized natural gas to homes. For years, its engineers have known that sulfur compounds in the gas corrode a particular brand of customer-owned brass stove connector made with phosphorous brazing, eventually causing separation and leaks, but the company never notified customers using that connector. After one fails in Dana Ruiz's kitchen and causes an explosion, her estate sues for negligent failure to warn.

Which is the strongest argument that Meadow Vale Gas owed Dana a duty?

Explanation. The majority recognized a limited common law duty of reasonable care where a gas utility has actual knowledge that its gas interacts with customer-owned brazed connectors to create a hidden danger not normally associated with the product, and the utility has superior knowledge of that hazard. In that circumstance, reasonable care may include warning customers. The court rejected any notion that the utility is an insurer, and it did not impose a general duty to inspect or replace all customer equipment. (Derived from Adams v. Northern Illinois Gas Co.
