What type of properties are covered under boiler and machinery insurance?

Boiler and machinery insurance specifically covers machinery and equipment that are integral to the operations of a business, particularly those that involve steam, pressure, or mechanical systems. This includes items like boilers, generators, pumps, compressors, and turbines, all of which are critical for various industrial operations. The coverage protects against breakdowns, malfunctions, and other risks that could lead to costly repairs and business interruptions.

The other options, while they mention different types of equipment, do not align with the specific coverage that boiler and machinery insurance provides. Tools and office equipment may be covered under general property insurance or specialized policies, but they do not fall under the category of boiler and machinery. Similarly, vehicles and aircraft are covered under other types of insurance, such as automobile or aviation insurance, which are separate from the scope of boiler and machinery insurance.
