Which of the following equipment types is specifically excluded from boiler and machinery covered equipment?

Vending machines are specifically excluded from the coverage typically afforded under boiler and machinery insurance policies. These policies are designed to cover equipment that is primarily related to the operation of boilers and machinery, such as pressure vessels and electric generators, which are integral to the functioning of industrial or commercial processes involving heat and pressure.

Communication and computer equipment, while also excluded, is often thought to have a different relationship to boiler and machinery operations as they are mainly used for information processing rather than for mechanical functions. Pressure vessels and electric generators, in contrast, are explicitly included in such policies because they are recognized as necessary components for operations that involve significant risk and require specialized coverage due to the potential hazards associated with their functioning.

Vending machines, which are essentially retail devices, do not fit this category. Their sole purpose is to dispense products, and they do not present the same operational risks as machinery or devices involved in high-pressure or high-heat applications, making their exclusion understandable in the context of boiler and machinery insurance.
