What is property and casualty insurance?  Honestly, before I was involved in the industry, I had very little knowledge of the many types of insurance included under the property/casualty category.  Technically, property insurance protects a person or business with an interest in physical property against its loss or the loss of its income-producing abilities.  Casualty insurance mainly protects a person or business against legal liability for losses caused by injury to other people or damage to the property of others. 

Many commercial lines of insurance include coverage for automobile, liability for business owners, equipment breakdown, farm, market segments, medical professional liability, property, and workers compensation.

Personal lines include coverage for automobile, property, homeowners, personal liability, and watercraft. 

Anything that could run a risk of a lawsuit against yourself or your business should be considered in seeking out property and casualty insurance.  Also, anything you own that is essential in your ability to produce income should definitely be insured as well.
