In CPCU 500, commercial liability exposures are often categorized bywhenandhowthe injury-causing event arises in relation to the insured's work. For contractors, a key distinction is between liability arising fromongoing workversus liability arisingafter the work has been finishedand put to its intended use. That distinction maps directly to "premises and operations" versus "completed operations." Here, the fire started because offaulty work recently completedby the contractor, and John's injury results from that completed work. Once the contractor has finished the job and left the site, injuries or property damage caused by the defective workmanship fall undercompleted operations liability. This is commonly addressed in a Commercial General Liability framework under the "products-completed operations hazard," which is designed for losses occurring away from the contractor's active operations and after completion.
The other options do not fit the facts.Products liabilitytypically involves injury or damage caused by a product that is manufactured, sold, or distributed (even though completed operations is conceptually similar, the prompt focuses on a contractor's completed work rather than a manufactured product).Employers liabilityrelates to employee injuries arising out of employment, which is not indicated here.Premises and operations liabilityapplies while work is in progress or tied to active operations at the site; the question explicitly says the faulty work was recently completed, pointing to completed operations rather than ongoing operations.
