“Open-Perils Coverage” is a form that shows that commercial property insurance has exclusions to the insurance policy.  When the peril is open, the insurer proves that there is an exclusion, but if the peril is specific then the insured must prove and give evidence about loss coverage for proximate cause.  The picture illustrates this point by giving bullet points about property exclusions that include the idea of open perils and examples of what they would be in insurance company policies.
