What is the difference between an accident and an incident?
As used in pipeline safety regulations, an incident is an event occurring on a natural gas pipeline for which the operator must make a report to the Office of Pipeline Safety. Events of similar magnitude affecting hazardous liquid pipelines are considered accidents. (Reference 49CFR 191.3, 49CFR 195.50).
