CPCU 500 explains liability loss exposures by focusing on when and where the injury occurs and what activity caused it. Premises and operations liability arises from conditions on the insured's premises or from the insured's ongoing business operations. The key idea is that the alleged negligence is tied to what the business is doing right now, such as maintaining safe walkways, conducting demonstrations, moving inventory, or interacting with customers.

In this scenario, the customer is injured on the nursery's premises after tripping over equipment left in an aisle. The hazard is a temporary unsafe condition created during normal business activity, and the injury occurs while the nursery is open and operating. That is the classic pattern of premises and operations exposure: a third party bodily injury claim arising from unsafe premises conditions or ongoing operations.

The other options do not fit CPCU 500's definitions. Completed operations involves injury or damage that occurs after the business has finished its work away from the premises or after the work has been completed, such as a contractor's faulty installation causing injury later. Products liability involves injury or damage caused by a product after it has been sold or distributed, typically away from the seller's premises. Employers liability relates to employee injury claims connected to employment, which is not the case here because the injured person is a customer, not an employee.
